NHA Patient Care Technician (CPCT) — All Questions

A patient care technician counts a resting adult patient's radial pulse and gets 78 beats per minute. How should this finding be classified?

• a.Below normal, indicating possible shock
• b.Bradycardia requiring immediate provider notification
• c.Tachycardia requiring immediate provider notification
• d.Within the normal adult range of 60-100 beats per minute✓

The normal resting heart rate for an adult is 60 to 100 beats per minute, so 78 bpm is normal. Bradycardia is a rate below 60 bpm and tachycardia is a rate above 100 bpm. No urgent notification is needed for a normal reading.

What is the normal respiratory rate range for a resting adult?

• a.6 to 10 breaths per minute
• b.30 to 40 breaths per minute
• c.12 to 20 breaths per minute✓
• d.24 to 30 breaths per minute

A normal adult resting respiratory rate is 12 to 20 breaths per minute. Rates below 12 indicate bradypnea and rates above 20 indicate tachypnea. Count respirations for a full minute for the most accurate result when the rate is irregular.

According to widely accepted guidelines, a normal adult blood pressure reading is closest to which value?

• a.140 over 90 mm Hg or higher
• b.120 to 129 over less than 80 mm Hg
• c.Less than 120 over less than 80✓
• d.About 90 over 50 mm Hg at rest

Under the 2017 ACC/AHA categories, normal adult blood pressure is a systolic below 120 mm Hg AND a diastolic below 80 mm Hg. The closest competitor, 120 to 129 over less than 80, is a real category but it is called elevated, not normal. Stage 1 hypertension begins at 130 to 139 systolic or 80 to 89 diastolic, and 140 over 90 or higher is stage 2. A reading around 90 over 50 is low and may represent hypotension in a symptomatic patient.

A technician takes an oral temperature and records 98.6°F. Which statement about this reading is correct?

• a.It is the accepted normal average oral body temperature✓
• b.Oral temperature is always 1 degree higher than rectal
• c.It is below normal and suggests hypothermia
• d.It indicates a low-grade fever

98.6°F (37°C) is the accepted average normal oral body temperature. Rectal temperatures typically run about 1°F higher than oral, and axillary temperatures run about 1°F lower. A fever is generally defined as an oral temperature of 100.4°F or higher.

A technician is checking a patient for orthostatic hypotension. After measuring blood pressure while the patient is lying down, what is the correct next step?

• a.Measure the pulse only and not the blood pressure
• b.Wait 30 minutes before taking the next reading
• c.Have the patient stand and re-measure pressure and pulse✓
• d.Give the patient fluids before any further readings

Orthostatic, or postural, vital signs are taken with the patient lying down, then repeated after the patient sits or stands, and both the blood pressure and the pulse are recorded at each position. A drop of 20 mm Hg systolic or 10 mm Hg diastolic, or a rise in pulse of about 20 beats per minute, suggests orthostatic hypotension. Recording only the pulse loses the measurement the test is built around, and waiting half an hour lets the pressure re-equilibrate so the change is missed. Fluids are a treatment decision, not part of taking the readings. Guard the patient against falling during the position change.

A pulse oximeter reads 97% on room air for a stable adult. How should the technician interpret this value?

• a.Normal only for patients receiving oxygen
• b.Abnormally high, remove the sensor
• c.Within the normal range of 95-100%✓
• d.Critically low, apply oxygen immediately

A normal oxygen saturation (SpO2) for a healthy adult on room air is 95% to 100%. Readings below 90% generally indicate hypoxemia and require prompt attention. Cold fingers, nail polish, and poor perfusion can produce falsely low readings.

A patient with difficulty breathing is most likely to be positioned in which way to ease respiration?

• a.Trendelenburg, with the head positioned lower than the feet and hips
• b.High-Fowler's, with the head of the bed at 60 to 90 degrees✓
• c.Prone, with the face turned to one side and the arms down
• d.Flat supine with no pillow under the head or the knees

High-Fowler's position raises the head of the bed to roughly 60 to 90 degrees, which lets the diaphragm drop and the lungs expand, easing the work of breathing. Semi-Fowler's, at about 30 to 45 degrees, is the milder version of the same idea. Lying flat, prone, or in Trendelenburg pushes the abdominal contents against the diaphragm and makes dyspnea worse.

Before transferring a weak but weight-bearing patient from bed to a wheelchair, the technician applies a gait belt. Where should the belt be positioned?

• a.Loosely fastened around the neck and both shoulders
• b.High under the armpits and across the chest
• c.Around the patient's thighs, just above both knees
• d.Snugly around the patient's waist over clothing✓

A gait belt, also called a transfer belt, goes snugly around the patient's waist over clothing so the technician can grasp it with an underhand grip and control the transfer. Placing it under the arms puts the lifting force on the rib cage and shoulder joints, and around the neck it can strangle. A belt around the thighs gives no control over the trunk, which is where the patient's balance is lost. Clothing under the belt protects the skin.

A technician is assisting a patient to ambulate with a cane. On which side should the patient hold the cane?

• a.In whichever hand feels most comfortable
• b.Directly in front of the body, centered
• c.On the weaker side, next to the weak leg
• d.On the stronger side, opposite the weak leg✓

A cane is held on the strong side of the body, opposite the affected leg, and the cane and the weak leg move forward together so that support arrives at the same moment the weak leg takes weight. Holding it on the weak side crowds the leg it is meant to help and narrows the base of support. Holding it in front or in whichever hand feels natural gives no consistent support and is a common cause of falls.

When providing oral care to an unconscious patient, which action best prevents aspiration?

• a.Lay the patient flat on the back during care
• b.Pour a full cup of water into the mouth to rinse
• c.Position the patient side-lying with the head turned✓
• d.Use large amounts of toothpaste and foam

An unconscious patient cannot protect the airway, so oral care is given side-lying with the head turned to the side, which lets fluid drain out of the mouth instead of pooling in the throat. Only small amounts of moisture are used, with suction available. Lying flat pools fluid at the back of the throat, and flooding the mouth with water or foam gives the patient more to aspirate rather than less.

When performing perineal care on a female patient, in which direction should the technician cleanse?

• a.From side to side repeatedly with the same cloth
• b.From back to front, toward the urethra
• c.In a circular scrubbing motion
• d.From front to back, away from the urethra✓

Perineal care on a female patient is performed front to back, moving away from the urethra toward the rectum. This prevents transferring bacteria from the anal area to the urethra, reducing the risk of urinary tract infection. A clean section of the washcloth is used with each stroke.

A technician is measuring fluid intake and output (I&O). Which of the following is counted as output?

• a.Urine and emesis (vomit)✓
• b.Intravenous fluids infused
• c.Gelatin eaten at lunch
• d.Water consumed with medications

Output includes measurable fluids leaving the body such as urine, emesis, liquid stool, and wound drainage. Intake includes oral fluids, IV fluids, and foods that are liquid at room temperature like gelatin and ice cream. Accurate I&O helps monitor a patient's fluid balance.

A patient drank 240 mL of juice, 120 mL of water, and a 180 mL cup of broth. What is the total recorded intake?

• a.360 mL
• b.600 mL
• c.420 mL
• d.540 mL✓

Adding the fluids: 240 + 120 + 180 = 540 mL. Broth is a liquid and is counted as intake. Accurate addition of all consumed fluids is essential for reliable I&O documentation.

To reduce the risk of catheter-associated urinary tract infection, how should the technician position the urinary drainage bag?

• a.Below the level of the bladder at all times✓
• b.On the bed beside the patient's legs
• c.Hooked to the movable upper side rail
• d.Level with the bladder on the bed frame

The drainage bag is kept below the level of the bladder at all times so urine flows away by gravity and cannot run back into the bladder, which is how bacteria are carried upward. Hanging it level with the bladder stops the downhill flow, and hooking it to a movable side rail means the bag rises above the bladder every time the rail goes up. Putting the bag on the bed places it above bladder level and on a contaminated surface. The bag must also never touch the floor, and the tubing is kept free of kinks.

A bedbound patient is at risk for pressure injuries. How often should the technician typically reposition the patient?

• a.Only when the patient asks
• b.Once per shift
• c.At least every 2 hours✓
• d.Every 6 hours

Repositioning an immobile patient at least every 2 hours relieves prolonged pressure over bony prominences and helps prevent pressure injuries. A turning schedule and pressure-relieving surfaces support skin integrity. Frequently at-risk areas include the sacrum, heels, and hips.

A technician notices an area of intact skin over the sacrum that is reddened and does not blanch (turn white) when pressed. This finding is most consistent with which stage of pressure injury?

• a.Stage 1✓
• b.Unstageable
• c.Stage 4
• d.Stage 3

A Stage 1 pressure injury is intact skin with non-blanchable redness, usually over a bony prominence. In darker skin, it may appear as a change in color or temperature rather than redness. It should be reported and pressure relieved immediately to prevent progression.

While assisting with a dressing change, a technician observes that the patient's wound has increased redness, warmth, swelling, and yellow-green drainage with odor. What is the most appropriate action?

• a.Cover it and say nothing, since drainage is expected
• b.Report the findings to the nurse as possible infection✓
• c.Apply a warm heating pad to the area for comfort
• d.Cleanse the wound with alcohol independently

Increased redness, warmth, swelling, purulent yellow-green drainage, and odor together are classic signs of a wound infection, and the technician reports them promptly to the nurse. Some drainage can be expected from some wounds, which is what makes the do-nothing answer tempting, but purulent drainage with odor and spreading warmth is not the expected kind. Assessing a wound, applying heat, and choosing a cleansing agent are all outside the technician's scope.

Restorative care focuses primarily on which goal for the patient?

• a.Helping the patient regain the highest possible independence✓
• b.Completing every task for the patient so that the unit saves time
• c.Discouraging self-care so that the patient avoids fatigue
• d.Keeping the patient in bed to prevent any risk of injury

Restorative care aims at restoring and maintaining function, mobility, and dignity by having the patient do as much as they safely can for themselves. Doing everything for a capable patient is faster in the moment and is the answer that feels kind, but it produces dependence and deconditioning. Bed rest and discouraged self-care accelerate the same decline, costing muscle strength and balance within days.

A technician performs passive range-of-motion (ROM) exercises on a patient who cannot move a joint independently. What defines this type of exercise?

• a.The technician moves the joint through its normal range✓
• b.Weights are added to the joint to increase resistance
• c.The patient moves the joint without any assistance
• d.The joint is moved quickly past the resistance point

Passive range of motion means the technician moves the patient's joint through its normal range because the patient cannot do it independently. The movements are slow and gentle and stop at the point of pain or resistance, which is what prevents injury to a joint that cannot signal well. A patient moving the joint alone is active range of motion, and adding resistance is strengthening exercise. Passive range of motion helps prevent contractures and maintains joint mobility.

When feeding a patient who has had a stroke with left-sided weakness, which action promotes safe swallowing?

• a.Have the patient lie down flat while eating and drinking slowly
• b.Tilt the head back so that the food goes down more easily
• c.Feed at a quick pace to finish before the patient gets tired
• d.Place food on the stronger side and sit the patient upright✓

Food is placed on the unaffected, stronger side of the mouth and the patient sits upright at about 90 degrees, which reduces pocketing of food in the weak cheek and lowers aspiration risk. The chin is slightly tucked, not tilted back: tilting the head back opens the airway and makes aspiration more likely, even though it feels like it helps gravity. Eating flat is unsafe for the same reason, and rushing removes the time the patient needs to clear each bite.

Before assisting a patient into a tub bath, what is the safest water temperature range?

• a.About 80-85°F (cool)
• b.Whatever temperature the patient prefers, without checking
• c.About 100-105°F (comfortably warm)✓
• d.About 120-130°F (very warm)

Bath water should be about 100 to 105°F, comfortably warm but not hot enough to burn fragile skin. The technician should always check the temperature with a thermometer or the inner wrist before the patient enters. Older adults and those with reduced sensation are especially vulnerable to scald burns.

When making an occupied bed, which action best protects the technician's back and the patient's safety?

• a.Raise the bed to hip height and keep the far rail raised✓
• b.Lower the bed fully and bend at the waist to work
• c.Work alone no matter how large the patient is
• d.Keep the far side rail lowered while turning

Raising the bed to about hip height lets the technician work with a straight back instead of bending, and keeping the far side rail up stops the patient from rolling off the far edge during the turn. The bed is returned to its lowest position once care is finished. Working at a low bed forces sustained forward flexion, which is how back injuries happen, and turning a patient toward a lowered rail removes the only barrier on that side.

Where is the apical pulse best auscultated with a stethoscope?

• a.Fifth intercostal space, left midclavicular line✓
• b.At the wrist, on the thumb side of the forearm
• c.Over the carotid artery in the neck
• d.At the antecubital fossa of the inner arm

The apical pulse is heard over the apex of the heart at the fifth intercostal space in the left midclavicular line, and it is counted with a stethoscope for a full 60 seconds. It is the most accurate site when the rhythm is irregular, because irregular beats that are too weak to reach the wrist are still heard at the chest. The radial site at the wrist, the carotid in the neck, and the brachial site at the antecubital fossa are palpated or used for blood pressure rather than for an apical count.

A technician palpates a patient's radial pulse and notes it is regular. For how long may the pulse be counted, and what is done with the result?

• a.Count for 15 seconds and multiply by 3
• b.Count for 30 seconds and multiply by 2✓
• c.Count for 10 seconds and multiply by 4
• d.Estimate without counting

A regular radial pulse may be counted for 30 seconds and multiplied by 2 to obtain the rate per minute. If the pulse is irregular, it must be counted for a full 60 seconds for accuracy. The radial pulse is palpated with the fingertips, never the thumb, which has its own pulse.

A patient states they feel dizzy and unsteady while walking in the hallway. What should the technician do first?

• a.Have the patient bend forward and keep moving
• b.Leave the patient to go and get the nurse
• c.Tell the patient to keep walking to the room
• d.Ease the patient to the floor or a chair and stay✓

A patient who becomes dizzy while walking is eased to the floor or into a nearby chair, using the gait belt and protecting the head, and the technician stays with the patient and calls for help. Trying to hold a falling adult fully upright injures both people. Leaving an unsteady patient alone to fetch help is the answer that sounds responsible and is the one that produces an unwitnessed fall.

The Sims' position is most commonly used for which purpose?

• a.Administering an enema or rectal care✓
• b.Measuring blood pressure accurately
• c.Feeding a patient an entire meal
• d.Promoting maximal lung expansion

Sims' position is a left side-lying position with the upper knee flexed toward the chest, used for enemas, rectal examinations, and rectal care, because it gives access to the rectal area and follows the natural curve of the sigmoid colon. Lung expansion is promoted by Fowler's positions, and a patient is fed sitting upright. Pillows are used to support the upper arm and leg so the patient stays comfortable and aligned.

A patient lying flat on the back facing upward is in which position?

• a.Fowler's
• b.Lateral
• c.Supine✓
• d.Prone

Supine is lying flat on the back facing upward. Prone is lying on the abdomen facing downward, and lateral is side-lying. Knowing standard positioning terms ensures clear communication and correct patient care.

When a patient is in the lateral (side-lying) position, which bony areas require padding to prevent pressure injuries?

• a.The greater trochanter, the shoulder, and the ankles✓
• b.The abdomen and the entire front surface of the chest wall
• c.The sacrum, the heels, and the back of the head and ears
• d.The elbows and the back of the head alone

Side-lying puts the body weight on the greater trochanter of the hip, the shoulder, the ear, and the ankles, so those are the points that need padding. The sacrum, heels, and back of the head are the pressure points of the supine position, which is why that answer is close but describes a different position. Pillows placed between the knees and behind the back hold the alignment and take load off the bony points.

A patient with dysphagia (difficulty swallowing) is about to eat. Which position best reduces the risk of aspiration during and after the meal?

• a.Lying flat on the back with the head turned to one side
• b.Upright at 90 degrees, and upright 30 minutes after✓
• c.Reclined at about 30 degrees throughout the entire meal
• d.Lying on the left side during and after the whole meal

A patient with dysphagia sits fully upright at about 90 degrees to eat and stays upright for at least 30 minutes afterward, so gravity carries food and fluid down and reflux does not reach the airway. Reclining part way is the near-miss: it is better than flat but still allows pooling and reflux in a patient who cannot protect the airway. Thickened liquids, small bites, and a slow pace may also be ordered by the care team.

A patient drank 4 ounces of water. How many milliliters should the technician record, knowing that 1 ounce equals approximately 30 mL?

• a.90 mL
• b.60 mL
• c.40 mL
• d.120 mL✓

Multiplying 4 ounces by 30 mL per ounce gives 120 mL. Converting household measures to milliliters ensures consistent I&O documentation. One ounce is roughly 30 mL, one cup (8 oz) is about 240 mL.

A patient's chart states 'NPO after midnight' for a scheduled procedure. In the morning the patient asks for water. What should the technician do?

• a.Offer ice chips freely, because ice is not counted as fluid
• b.Provide the full breakfast tray, since the patient is hungry
• c.Withhold food and fluids and tell the nurse of the request✓
• d.Give a small glass of water, because water is not really food

NPO means nothing by mouth, and that includes water and ice chips, which melt into fluid in the stomach exactly like a drink. The technician explains the reason kindly and tells the nurse that the patient is asking, so the team can decide whether anything may be given. Giving fluid can force the procedure to be cancelled or, under anesthesia, cause aspiration of stomach contents into the lungs.

A patient reports constipation. Which intervention, within the technician's role, generally supports normal bowel elimination?

• a.Discourage movement until the constipation resolves
• b.Encourage fluids, fiber, and activity as allowed✓
• c.Restrict all oral fluids until the bowel moves again
• d.Encourage prolonged bed rest until the problem resolves

Adequate fluid intake, fiber-rich foods, and as much activity as the patient is allowed all promote normal bowel function, and all three are within the technician's role. Immobility and dehydration are two of the most common causes of constipation in a hospitalized patient, so restricting fluids or enforcing rest makes the problem worse. Laxatives and enemas require an order and are given per facility policy.

To obtain the most accurate and consistent daily weight for a patient, the technician should weigh them:

• a.At the same time daily, before breakfast, similar clothing✓
• b.At different times each day, whenever the unit happens to be quiet
• c.Only when the patient reports feeling bloated or newly swollen
• d.Immediately after the patient finishes drinking fluids

Daily weights are taken at the same time each day, usually in the morning before breakfast, on the same scale and in similar clothing, and the patient voids first when possible. That consistency is the whole point: a two-pound change only means something if nothing else changed. Weighing at scattered times, or right after a drink, buries a real trend under normal daily variation, and weighing only when the patient feels swollen produces no trend at all.

Before ambulating a patient who has been on bed rest, the technician has the patient sit on the edge of the bed and dangle the legs for a few minutes. What is the main purpose of dangling?

• a.To count the patient’s respiratory rate before standing up
• b.To measure the patient’s leg strength before walking
• c.To give the patient’s feet time to warm up first
• d.To let the body adjust and avoid a dizzy spell✓

Dangling lets the patient sit with the legs over the side of the bed so the cardiovascular system can adjust to being upright, which is what prevents the orthostatic drop in pressure that causes dizziness and falls. The technician uses the time to ask about lightheadedness and to watch the patient's color before assisting to stand. Checking leg strength is a reasonable thing to notice but is not why the patient dangles, and respirations and warmth are not the purpose at all.

According to CDC guidance, which practice is considered the single most effective way to prevent the spread of infection in healthcare settings?

• a.Using a face mask during all care
• b.Performing proper hand hygiene✓
• c.Wearing a gown for every patient
• d.Wearing gloves at all times

Hand hygiene is recognized by the CDC as the single most effective measure to prevent the spread of healthcare-associated infections. It should be performed before and after patient contact, after glove removal, and after touching contaminated surfaces. Gloves and gowns supplement, but never replace, hand hygiene.CDC

A technician has cared for a patient with Clostridioides difficile (C. diff), whose spores are not killed by alcohol. What is the correct hand hygiene method after this care?

• a.A quick water rinse
• b.No hand hygiene is needed if gloves were worn
• c.Alcohol-based hand rub only
• d.Wash hands with soap and running water✓

C. diff spores are resistant to alcohol-based hand rubs, so hands must be washed with soap and running water to physically remove them. The friction and rinsing action mechanically removes spores that alcohol cannot destroy. Alcohol rubs are appropriate for most other organisms when hands are not visibly soiled.CDC

Standard precautions are applied to which patients?

• a.Only patients known to have an infection
• b.Only patients who are actively bleeding
• c.Only patients placed in isolation rooms
• d.All patients, regardless of diagnosis or status✓

Standard precautions are used for every patient at all times, because a patient who is infectious is often not yet known to be. They treat blood and all body fluids as potentially infectious and include hand hygiene, appropriate personal protective equipment, and safe handling of sharps and contaminated equipment. Transmission-based precautions, including isolation, are added on top for specific known or suspected infections.CDC

A patient is placed on contact precautions for a multidrug-resistant organism. What PPE should the technician don before entering the room to provide direct care?

• a.Surgical mask and goggles only
• b.No PPE is required
• c.Gown and gloves✓
• d.N95 respirator only

Contact precautions require a gown and gloves for direct patient contact or contact with the patient's environment. This prevents transfer of organisms spread by touch, such as MRSA and VRE. Dedicated or disposable equipment is also used and cleaned between patients.CDC

Droplet precautions are used for organisms spread by respiratory droplets. How far do these large droplets typically travel?

• a.Roughly 20 feet, carried on air currents
• b.Roughly 30 feet, throughout the room
• c.They stay suspended and travel building-wide
• d.Roughly 3 to 6 feet before falling✓

Large respiratory droplets are heavy enough that gravity pulls them out of the air within about 3 to 6 feet, which is why droplet precautions call for a surgical mask when working within that distance of the patient. Influenza and pertussis are the standard examples. The longer distances describe airborne transmission, where droplet nuclei are small enough to stay suspended and travel on air currents through a room or a ventilation system, and those organisms need an N95 respirator and a negative-pressure room instead.CDC

A technician must enter the room of a patient with active pulmonary tuberculosis, which spreads by airborne transmission. Which respiratory protection is required?

• a.No mask if staying near the door
• b.A standard surgical procedure mask
• c.A fit-tested N95 respirator or higher✓
• d.A cloth face covering worn snugly

Airborne precautions for tuberculosis require a fit-tested N95 or higher-level respirator, because the infectious particles are small enough to stay suspended in the room air and travel on air currents. A surgical mask is designed to catch large droplets and to protect the patient from the wearer, so it does not filter these particles; a cloth covering does even less. The patient is also placed in an airborne infection isolation room with the door kept closed, and distance from the patient does not substitute for a respirator.CDC

What is the correct sequence for donning (putting on) personal protective equipment?

• a.Mask or respirator, then gown, goggles, gloves
• b.Gown, mask or respirator, goggles, gloves✓
• c.Gown, gloves, then mask and goggles last
• d.Goggles, gown, gloves, then mask last

The donning order is gown first, then mask or respirator, then goggles or face shield, and gloves last, so the gloves can be pulled over the gown cuffs and seal them. Any order that puts gloves on before the mask and eye protection means touching the face with gloved hands, and any order that starts with the mask leaves the gown to be tied afterward over already-protected equipment. Doffing runs in a different order, with gloves removed first.CDC

When doffing (removing) PPE after patient care, which item is generally removed first?

• a.The goggles, before anything else
• b.The gown, with the gloves still on
• c.The mask or respirator, at the doorway
• d.The gloves, still at the bedside✓

Gloves come off first because they are the most contaminated item and everything they touch afterward becomes contaminated too. The usual sequence is gloves, then goggles or face shield, then gown, and the mask or respirator last, removed outside the room so the wearer is still protected while inside it. The gown-before-gloves answer is the near miss: gown and gloves may be peeled off together as one bundle, but the gown is not removed while gloved hands are still bare to the room. Hand hygiene follows immediately.CDC

Under the OSHA Bloodborne Pathogens Standard, what is the correct way to handle a contaminated needle after use?

• a.Place it in the regular trash can at the bedside
• b.Do not recap it; use the sharps container✓
• c.Bend the needle before placing it in the trash
• d.Recap it by hand and set it aside for later

The OSHA Bloodborne Pathogens Standard prohibits recapping, bending, or breaking contaminated needles by hand and requires immediate disposal into a labeled, puncture-resistant, leak-proof sharps container. Most needlesticks happen in the seconds between use and disposal, which is why the needle goes straight into the container rather than onto a tray. Regular trash exposes housekeeping staff, and hand-recapping points the needle back at the technician's own fingers.OSHA 29 CFR 1910.1030

A sharps container is about three-quarters full. What is the appropriate action?

• a.Continue filling it until it overflows
• b.Empty it into the regular trash and reuse it
• c.Close and replace it before it becomes overfilled✓
• d.Push the contents down to make more room

Sharps containers should be replaced when they reach the fill line, generally about two-thirds to three-quarters full, and never overfilled. Overfilling increases the risk of needlestick injury when adding or removing items. Containers must never be emptied by hand or reused, per OSHA requirements.OSHA 29 CFR 1910.1030

Using proper body mechanics, how should a technician lift a heavy object from the floor?

• a.Keep the legs straight and twist the trunk while lifting
• b.Bend at the waist and lift with the back muscles
• c.Bend at the knees and hips and lift with the legs✓
• d.Hold the object away from the body while lifting

Proper lifting means bending at the knees and hips with the back straight and letting the strong leg muscles do the work, with the object held close to the body and the feet about shoulder-width apart for a stable base. Holding a load away from the body multiplies the force on the lower back even when the knees are bent, which is what makes that answer tempting and still wrong. Twisting while loaded is a common mechanism of back injury; the whole body is turned instead.

A technician enters a room and finds a patient's call light out of reach and the bed in a high position. Which action reduces this patient's fall risk?

• a.Leave the bed raised so that care access is easier
• b.Lower the bed and put the call light within reach✓
• c.Keep the room dimly lit throughout the day and night
• d.Remove the patient's non-slip footwear

Both problems in the scenario are fixed by the same action: the bed goes to its lowest position so a patient who does get up has a short distance to the floor, and the call light goes within reach so the patient can ask for help instead of climbing out. A raised bed is genuinely easier for staff to work at, which is why it is left up, and that is exactly the habit that causes falls when the room is left. Adequate lighting, non-slip footwear, and clear pathways are the rest of the fall-prevention package.

During a fire, the acronym RACE guides the response. What does RACE stand for?

• a.Rescue, Alarm, Confine, Evacuate in reverse order
• b.Report, Assist, Cover, Exit
• c.Rescue, Alarm, Contain, Extinguish✓
• d.Run, Alert, Contain, Escape

RACE stands for Rescue anyone in immediate danger, Alarm by activating the fire alarm and calling for help, Confine the fire by closing doors, and Extinguish the fire if small and safe or Evacuate. Following RACE provides an organized response that protects patients and staff. Staff should know the location of alarms and extinguishers.

When using a fire extinguisher, the acronym PASS is followed. What does PASS stand for?

• a.Point, Alarm, Squeeze, Stop
• b.Pull, Aim, Squeeze, Sweep✓
• c.Pull, Alert, Spray, Signal
• d.Push, Aim, Slide, Sweep

PASS stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side. Aiming at the base rather than the flames targets the fuel source. This technique should be used only on small, contained fires when it is safe to do so.

A technician finds a patient unresponsive and not breathing. After ensuring scene safety, what is the immediate priority action?

• a.Offer the patient a sip of water and try to rouse him
• b.Activate the emergency response and start CPR✓
• c.Leave the room to document the finding before anything else
• d.Wait ten minutes to see whether the patient recovers alone

An unresponsive patient who is not breathing is in cardiac arrest until proven otherwise, so the emergency response system is activated at once and CPR is started if the technician is trained and it is within scope. Survival falls with every minute without compressions. Nothing is given by mouth to an unresponsive patient, and leaving to document or waiting to see what happens spends the only minutes that matter.

A confused patient keeps trying to climb out of bed. According to safe practice, restraints should be:

• a.Used as a last resort, with a provider's order✓
• b.Applied whenever the unit happens to be short of staff
• c.Applied right away for any confused patient
• d.Tied to the movable side rail for quick release

Restraints are a last resort used only after less restrictive alternatives such as a bed alarm, closer observation, and frequent toileting have been tried, and they require a provider's order. They are never applied for staff convenience or as discipline, and confusion alone is not an indication. When one is used it is secured to the non-movable part of the bed frame with a quick-release knot, because a restraint tied to a side rail is pulled and tightened every time the rail is raised or lowered.

A patient is in a physical restraint. How often should the technician typically check the patient and release the restraint for circulation, toileting, and repositioning?

• a.Every 4 hours, according to the provider's order
• b.Only at the end of the day, before the night shift
• c.Once during each shift, at the change of shift
• d.At least every 2 hours, per facility policy✓

A restrained patient is monitored frequently and the restraint is typically released at least every two hours for repositioning, range of motion, toileting, and skin and circulation checks, with facility policy and the provider's order setting the exact interval. Longer intervals allow pressure injury, impaired circulation, and the loss of dignity that restraint use is meant to minimize. Every check and the patient's response are documented.

When removing a contaminated isolation gown, which part is considered the most contaminated and should not touch the technician's clothing?

• a.The inside of the back of the gown
• b.The inner surface of the sleeves
• c.The front and the sleeves of the gown✓
• d.The neck ties and the waist ties

The front and the sleeves of an isolation gown are treated as the most contaminated surfaces, because they face the patient and the environment throughout care, and they must not touch the technician's uniform during removal. The gown is unfastened at the neck and waist and then peeled away and rolled inward so the contaminated surface ends up on the inside of the bundle. The inside back of the gown is considered clean, which is why it is the surface that touches the technician. Hand hygiene is performed immediately after removal.CDC

According to the standard order of draw, which specimen is collected first when a blood culture is ordered along with other tests?

• a.Lavender (EDTA) hematology tube
• b.Blood culture (sterile) tubes or bottles✓
• c.Light blue (sodium citrate) tube
• d.Red top (no additive) serum tube

Blood cultures are drawn first so the sterile bottles are filled before the needle and the site have any chance to pick up contamination from another tube's stopper. A single skin organism carried into a culture bottle can produce a false positive that costs the patient days of antibiotics. The CLSI order then runs light blue, serum tubes, green, lavender, and gray, which prevents additive carryover between tubes.

In the CLSI order of draw, which tube is collected immediately after blood culture bottles?

• a.Light blue (sodium citrate) tube✓
• b.Lavender (EDTA) hematology tube
• c.Gray (sodium fluoride) tube
• d.Green (lithium heparin) tube

The light blue sodium citrate tube for coagulation studies is drawn immediately after the blood culture bottles. It comes early because carryover of EDTA or heparin from another stopper would alter clotting results, and citrate results are the most sensitive to contamination of any tube in the sequence. The order then continues with serum tubes, green, lavender, and gray.

A lavender-top (purple) tube is required for a complete blood count (CBC). Which additive does it contain?

• a.EDTA, which chelates calcium✓
• b.Sodium citrate, a reversible chelator
• c.Sodium fluoride, an antiglycolytic
• d.Lithium heparin, a thrombin inhibitor

The lavender-top tube contains EDTA, which binds calcium irreversibly and preserves cell shape and size, which is what a complete blood count depends on. Sodium citrate is the near miss worth knowing: it also works by binding calcium, but it does so reversibly and at a fixed 9-to-1 ratio for coagulation testing, so mechanism alone does not tell the two apart, only the tube and the test do. Fluoride preserves glucose rather than preventing clotting outright, and heparin inhibits thrombin and is used for plasma chemistry. Every additive tube is gently inverted after collection or it clots and the sample is lost.

A green-top tube is used for many chemistry (plasma) tests. Which additive does it contain?

• a.A silica clot activator with gel
• b.EDTA, used for hematology
• c.Sodium citrate, for coagulation
• d.Heparin, lithium or sodium✓

The green-top tube contains heparin, most often as the lithium or sodium salt, which inhibits thrombin and so yields plasma for chemistry testing without waiting for a clot. The cation matters in practice: a lithium level is never drawn into lithium heparin, and a sodium level is never drawn into sodium heparin. A silica clot activator with a separator gel is the serum separator tube, which is the opposite intent, and EDTA and citrate are the hematology and coagulation anticoagulants.

A gray-top tube containing sodium fluoride is most appropriate for which test?

• a.Glucose or lactate levels✓
• b.Coagulation studies (PT/INR)
• c.Blood typing
• d.Complete blood count

The gray-top tube contains sodium fluoride, an antiglycolytic agent that preserves glucose by preventing cells from metabolizing it, making it ideal for glucose and lactate testing. Potassium oxalate is often included as an anticoagulant. It is drawn last in the standard order of draw.

A plain red-top tube (no additive or with clot activator only) is typically used to collect which specimen type?

• a.A sterile blood culture
• b.Plasma requiring immediate anticoagulation
• c.Whole blood with anticoagulant
• d.Serum, after the blood clots✓

A plain red-top tube has no anticoagulant, so the blood is allowed to clot and then centrifuged to yield serum. Serum is used for many chemistry, serology, and blood bank tests. Because it contains no additive, a plain red tube does not require inversion to mix, though clot-activator tubes are inverted.

At what angle should the needle be inserted during a routine venipuncture?

• a.Parallel to the skin at 5 degrees
• b.45 to 60 degrees
• c.Straight down at 90 degrees
• d.15 to 30 degrees, bevel up✓

The needle is inserted at a 15 to 30 degree angle with the bevel facing up during venipuncture. A shallow angle follows the path of the vein and reduces the risk of passing through it. Too steep an angle can puncture the back wall of the vein.

To avoid hemoconcentration and inaccurate results, a tourniquet should not remain in place longer than:

• a.3 minutes
• b.4 minutes
• c.1 minute✓
• d.5 minutes

A tourniquet should be left on for no longer than 1 minute to prevent hemoconcentration, which can falsely elevate certain results such as potassium and protein. If more time is needed to find a vein, the tourniquet is released and reapplied after two minutes. It is loosened as soon as blood flow is established.

Which vein is generally the preferred first choice for routine venipuncture in the antecubital area?

• a.Basilic vein
• b.A vein on the underside of the wrist
• c.Median cubital vein✓
• d.Cephalic vein of the wrist

The median cubital vein is usually the first choice for venipuncture because it is large, well-anchored, and located away from major nerves and arteries. The cephalic vein is a second choice, and the basilic vein is used with caution due to its proximity to the brachial artery and nerves. Veins on the underside of the wrist are avoided due to injury risk.

When performing a capillary (heel) puncture on an infant, which area of the heel should be used?

• a.The very center of the plantar surface
• b.The arch of the foot, behind the toes
• c.The medial or lateral plantar heel✓
• d.The posterior curve of the heel itself

Infant heel sticks are performed on the medial or lateral plantar surface of the heel, at the sides, because the calcaneus lies close to the skin at the center and at the back curve of the heel. Puncturing over bone can cause bruising, injury to the bone, or infection. The arch is avoided because nerves, tendons, and blood vessels run through it. Puncture depth is also limited for the same reason.

The order of draw for capillary (skin puncture) collection differs from venipuncture. Which specimen is generally collected first from a capillary stick?

• a.Coagulation tubes first, then EDTA, then the serum tubes
• b.Blood gases, then EDTA, then additives, then serum✓
• c.Serum tubes first, then EDTA tubes, then the blood gases
• d.Chemistry tubes first, then the EDTA and blood gas tubes

In capillary collection the order is blood gases first, then EDTA hematology tubes, then other additive tubes, and serum last. EDTA comes early so an adequate, well-mixed hematology sample is obtained before platelets begin clumping at the puncture site and the drop starts to clot. This is not the venipuncture order, where the light blue coagulation tube comes near the beginning and serum tubes come before the additive tubes.

Immediately after filling an additive tube, what must the technician do to properly handle the specimen?

• a.Shake it hard so the additive mixes in faster
• b.Place it on ice regardless of the test ordered
• c.Gently invert it the recommended number of times✓
• d.Spin it in a centrifuge immediately at the bedside

An additive tube is inverted gently the number of times the manufacturer specifies, immediately after it is filled, so the blood mixes with the additive before it can clot or clump. Vigorous shaking mixes it too, which is why that answer is tempting, but the shear force ruptures red cells and the resulting hemolysis makes many results unusable. Only certain tests require chilling, and specimens are centrifuged in the laboratory after the required clotting time, not at the bedside.

A technician receives a report that a specimen was hemolyzed. Which action during collection most likely caused the hemolysis?

• a.Gently inverting the tube five times
• b.Filling the tube completely
• c.Vigorously shaking the tube after collection✓
• d.Using an appropriately sized needle

Vigorous shaking of a tube ruptures red blood cells and causes hemolysis, which can falsely elevate results such as potassium. Other causes include using too small a needle, drawing too forcefully, or leaving the tourniquet on too long. Proper gentle mixing and technique prevent hemolysis.

A serum separator tube (SST), often gold or tiger-topped, contains which components?

• a.Sodium fluoride to preserve glucose
• b.An anticoagulant to prevent clotting
• c.EDTA for hematology testing
• d.A clot activator and a gel separator✓

An SST contains a clot activator to speed clotting and a thixotropic gel that forms a barrier between serum and cells after centrifugation. This yields a clean serum sample for many chemistry and serology tests. It is inverted five times after collection and allowed to clot before spinning.

A test requires a fasting specimen. A patient scheduled for a fasting glucose reports eating breakfast an hour ago. What should the technician do?

• a.Tell the patient to fast for one more hour, then draw
• b.Tell the nurse and document that the patient ate✓
• c.Draw the specimen anyway and say nothing to anyone
• d.Cancel the test permanently and remove it from the orders

A fasting specimen typically requires 8 to 12 hours with no food or caloric intake, so a breakfast an hour ago invalidates a fasting glucose. The technician reports the situation to the nurse or provider and documents the non-fasting status so someone with the authority to decide can reschedule the draw or accept a non-fasting result. One more hour does not restore a fasting state. Drawing without comment sends a result that will be read as fasting, and cancelling an order outright is not the technician's decision.

When should specimen tubes be labeled during the blood collection process?

• a.The next day, while charting the previous day's results
• b.At the bedside right after the draw, with patient✓
• c.Only when the specimen looks abnormal inside the tube
• d.Before the patient arrives, to save time during the draw

Tubes are labeled at the bedside immediately after collection, while the technician is still with the patient whose identity was just verified with two identifiers. Pre-labeling before the patient arrives is the dangerous near-miss: it feels efficient and it is how a tube ends up carrying the wrong patient's name, which is one of the most serious errors in the laboratory. The label carries the patient's name and identifiers, the date, the time, and the collector's initials.

When placing precordial (chest) leads for a 12-lead EKG, where is lead V1 positioned?

• a.Fourth intercostal space at the right sternal border✓
• b.Fourth intercostal space at the left sternal border
• c.Fifth intercostal space at the anterior axillary line
• d.Fifth intercostal space at the midclavicular line

Lead V1 is placed in the fourth intercostal space at the right sternal border. Accurate placement of V1 is critical because the other chest leads are positioned relative to it. Misplacement produces inaccurate waveforms and can lead to misinterpretation.

Where is lead V2 placed during a 12-lead EKG?

• a.Fourth intercostal space at the right sternal border
• b.Fifth intercostal space at the midaxillary line
• c.Fourth intercostal space at the left sternal border✓
• d.Fifth intercostal space at the midclavicular line

Lead V2 is placed in the fourth intercostal space at the left sternal border, directly across from V1. V1 and V2 straddle the sternum in the same intercostal space. Correct placement ensures reliable recording of the heart's electrical activity.

Lead V4 of a 12-lead EKG is correctly positioned at:

• a.The fifth intercostal space at the left midclavicular line✓
• b.The fourth intercostal space at the right sternal border
• c.The left midaxillary line level with V4
• d.The fourth intercostal space at the left sternal border

Lead V4 is placed in the fifth intercostal space at the left midclavicular line. V4 is generally positioned before V3, and V3 is placed midway between V2 and V4. Correct V4 placement anchors the horizontal plane of the remaining chest leads.

When applying limb electrodes for a 12-lead EKG, where should they generally be placed?

• a.On the chest near the heart, just under the collarbones
• b.On the fingertips and the toes, one on each side
• c.Over bony areas such as the wrist bone and ankle bone
• d.On fleshy areas of the arms and legs, off the bone✓

Limb electrodes go on fleshy areas of the arms and legs, away from bony prominences and heavy muscle, and they are placed symmetrically on both sides so the frontal-plane leads stay accurate. Bone conducts poorly and gives a weak, unstable signal, and muscle over a joint produces tremor artifact. Moving limb electrodes onto the torso changes the recorded leads and is done only under a specific protocol that is then documented.

A monitored patient has a regular rhythm with a rate of 76, a P wave before each QRS, and normal intervals. This rhythm is best described as:

• a.Ventricular tachycardia
• b.Normal sinus rhythm✓
• c.Atrial fibrillation
• d.Sinus bradycardia

Normal sinus rhythm has a regular rate of 60 to 100 beats per minute with a P wave preceding each QRS complex and normal intervals. A rate of 76 with these features is normal. Recognizing normal rhythm helps the technician identify deviations quickly.

A cardiac monitor shows a regular rhythm with a P wave before each QRS at a rate of 48 beats per minute. This is best described as:

• a.Sinus tachycardia
• b.Sinus bradycardia✓
• c.Atrial fibrillation
• d.Normal sinus rhythm

Sinus bradycardia is a regular sinus rhythm with a rate below 60 beats per minute, so a rate of 48 with normal P waves fits. It may be normal in athletes or during sleep but can cause symptoms if the rate is too slow. Symptomatic bradycardia should be reported to the nurse promptly.

A monitored patient's rhythm is regular with a normal-appearing complex and P waves, at a rate of 120 beats per minute. This is best described as:

• a.Sinus bradycardia
• b.Sinus tachycardia✓
• c.Asystole
• d.Normal sinus rhythm

Sinus tachycardia is a regular sinus rhythm with a rate above 100 beats per minute, so 120 with normal P waves fits. It can result from fever, pain, anxiety, dehydration, or exertion. The underlying cause should be identified and reported as appropriate.

An EKG tracing shows fuzzy, erratic spikes in the baseline caused by the patient shivering. What is the most likely cause of this artifact?

• a.Wandering baseline from breathing
• b.60-cycle electrical interference
• c.Somatic (muscle) tremor artifact✓
• d.A loose electrode

Somatic tremor artifact is caused by muscle movement such as shivering, tremors, or tension, producing fuzzy, erratic spikes on the tracing. Warming the patient and helping them relax can reduce it. Distinguishing artifact from true rhythm prevents misinterpretation.

An EKG shows a baseline that gradually drifts up and down across the tracing. This wandering baseline is most often caused by:

• a.An unrecognized run of ventricular fibrillation
• b.A normal variation seen in a healthy adult heart
• c.Movement, respiration, or loose electrodes✓
• d.Sixty-cycle interference from equipment

A wandering baseline is a slow up-and-down drift of the whole tracing, caused by patient movement or respiration or by loose, dried, or poorly attached electrodes. Sixty-cycle interference is the answer worth ruling out and looks completely different: a fine, fast, uniform fuzz rather than a slow roll. Good skin preparation and secure electrode contact correct the drift. Recognizing it as artifact is what keeps it from being reported as a rhythm abnormality.

A tracing shows a uniform, thick, fuzzy line with small regular spikes about 60 times per second. This artifact is most consistent with:

• a.Normal sinus rhythm at a very fast rate
• b.Somatic tremor caused by patient shivering
• c.A slowly wandering and drifting baseline
• d.Sixty-cycle AC electrical interference✓

Sixty-cycle interference produces a uniform band of small, perfectly regular spikes picked up from nearby electrical equipment, cords, or faulty grounding, and the giveaway is that the spikes repeat at exactly 60 per second. No physiologic source is that regular: muscle tremor from shivering is irregular and varies in size, and a wandering baseline is a slow roll rather than fine spikes. Unplugging non-essential devices and checking cables and the ground electrode reduces it.

An EKG shows an irregularly irregular rhythm with no clearly identifiable P waves. This is most consistent with:

• a.First-degree heart block
• b.Sinus bradycardia
• c.Atrial fibrillation✓
• d.Normal sinus rhythm

Atrial fibrillation appears as an irregularly irregular rhythm with no discernible P waves, replaced by a chaotic, wavy baseline. It results from disorganized electrical activity in the atria. The technician should document the finding and notify the nurse, especially if the rate is rapid or the patient is symptomatic.

A cardiac monitor suddenly shows a flat line and the patient is unresponsive with no pulse. After confirming the patient and checking leads, what does this rhythm represent and what is the priority?

• a.Normal rhythm; continue monitoring
• b.Sinus bradycardia; recheck in an hour
• c.Artifact; ignore it and reset alarms
• d.Asystole; call for help and start CPR now✓

A flat line in a patient who is unresponsive and pulseless is asystole, a cardiac arrest. The technician confirms the patient rather than the monitor first, which also rules out a disconnected lead, then activates the emergency response and begins CPR if trained. A lead that has come off produces the same flat line in a patient who is awake, which is why the patient is checked before the alarm is dismissed as artifact and why it must never be dismissed in a pulseless patient.

Lead V6 of a 12-lead EKG is placed at:

• a.The fourth space at the right sternal border
• b.The second intercostal space at the sternum
• c.The left midclavicular line, fourth space
• d.Fifth intercostal space at the left midaxillary line✓

V6 is placed at the fifth intercostal space in the left midaxillary line, horizontally level with V4 and V5, completing the lateral view. V5 sits between them at the anterior axillary line. The fourth intercostal space at the right sternal border is V1, and keeping V4, V5, and V6 on one horizontal plane rather than following the rib line is what makes the lateral leads comparable.

To obtain a clear EKG tracing, how should the technician prepare the skin before applying electrodes?

• a.Apply the electrodes over body lotion for better adhesion
• b.Place the electrodes directly over the thick chest hair
• c.Wet the skin thoroughly just before applying them
• d.Clean the site, clip excess hair, and abrade lightly✓

Good skin preparation means cleaning the site, clipping excess hair only where an electrode will sit, and lightly abrading dry or oily skin so the electrode makes solid contact with a low-resistance surface. Lotions and oils insulate the skin and are a frequent cause of wandering baseline. Hair holds the electrode off the skin, and wet skin lets the electrode slide and lift. Secure contact is what produces a clean, interpretable tracing.

A visitor asks a technician to confirm whether their neighbor is a patient and what condition they have. What is the correct response under HIPAA?

• a.Give general details but not the exact diagnosis
• b.Confirm the room number so the visitor can go up
• c.Politely decline and refer the request to staff✓
• d.Share the diagnosis, since they are neighbors

Under HIPAA a technician may not confirm that a person is a patient, let alone describe their condition, to someone who is not authorized. The technician politely declines and directs the request to the nurse or to whoever handles such requests under facility policy. Confirming a room number confirms that the person is here, which is protected information on its own, and giving general details still discloses health information.HIPAA

A competent patient refuses a bath that the technician planned to give. What is the appropriate response respecting patient rights?

• a.Respect the refusal, explain the benefits, and report it✓
• b.Give the bath anyway, because it is on the daily care schedule
• c.Wait until the patient is asleep and then proceed quietly
• d.Tell the patient that there is no choice about the bath

A competent patient has the right to refuse care, and bathing someone over that refusal can constitute battery. The technician respects the decision, explains the benefits so the patient can reconsider with good information, and reports and documents the refusal for the nurse. Waiting until the patient is asleep is not a workaround; it removes even the chance to refuse. A scheduled task does not override the patient's decision.

Which of the following is an example of objective data that a technician would document?

• a.A blood pressure reading of 128/82 mmHg✓
• b.The patient saying they slept poorly
• c.The patient's statement 'I feel nauseous'
• d.A report of a headache described by the patient

Objective data are measurable, observable facts such as a blood pressure reading, temperature, or visible wound drainage. Subjective data are what the patient reports, such as pain, nausea, or feelings. Documentation should clearly distinguish measured findings from patient statements.

A technician makes an error while charting on a paper record. What is the correct way to correct it?

• a.Use correction fluid to cover over the wrong entry
• b.Erase the mistake completely and then rewrite it
• c.Draw one line through it, initial and date it✓
• d.Scribble it out heavily so that it cannot be read

A paper charting error is corrected by drawing a single line through it so the original stays legible, marking it as an error, adding initials and the date, and then writing the correct entry. The record is a legal document, and anything that hides what was originally written, whether correction fluid, erasing, or scribbling, raises the question of what was being concealed. Leaving the original readable is what protects the technician as much as the patient.

A patient's family member asks the technician to adjust the dose of the patient's IV medication because the patient seems uncomfortable. What is the appropriate action within scope of practice?

• a.Turn off the IV pump to be on the safe side for now
• b.Tell the family it is fine to change it themselves
• c.Adjust the IV rate as the family requests
• d.Explain it is outside scope and tell the nurse✓

Adjusting a medication or an IV rate is outside a patient care technician's scope and belongs to a licensed nurse. The technician acknowledges the family's concern, explains the limit honestly, and reports the discomfort to the nurse promptly so it is actually addressed. Stopping the pump feels cautious but is also an unauthorized change to therapy, and telling the family to adjust it themselves hands the same problem to someone with even less training.

A patient appears anxious before a procedure. Which response by the technician is an example of therapeutic communication?

• a.’There is really no reason at all to be nervous.’
• b.'Do not worry, everything will be just fine.'
• c.Changing the subject to steer the patient away from the topic
• d.'You seem worried. Would you like to tell me about it?'✓

Therapeutic communication names what the technician observes and then invites the patient to say more, which keeps the conversation open and often reveals the specific fear. False reassurance and telling a patient not to feel what they feel are blocks: they end the conversation and leave the worry in place, even though they are meant kindly. Changing the subject does the same thing more obviously. Active listening builds trust and surfaces needs the team can act on.

A patient from a different cultural background declines to make direct eye contact and prefers a family member present during care. How should the technician respond with cultural competence?

• a.Insist that the patient make direct eye contact anyway
• b.Assume that the patient is being uncooperative today
• c.Respect the cultural preferences and adapt the care✓
• d.Ask the family member to leave the room

Cultural competence means recognizing that behavior carries different meanings in different cultures and adapting care accordingly. Avoiding direct eye contact is a sign of respect or deference in many cultures rather than disinterest or evasion, and family presence during care is expected in many others. Reading either as uncooperativeness leads to care that the patient will resist or refuse. Individualized, respectful care improves both trust and outcomes.

Who is responsible for obtaining a patient's informed consent for a medical procedure?

• a.The receptionist at the front check-in desk
• b.The provider performing the procedure✓
• c.The patient care technician on the unit
• d.Any staff member who happens to be available

Informed consent is obtained by the provider who will perform the procedure, because only that person can explain the risks, the benefits, and the alternatives and answer the patient's questions. Other staff may witness a signature, which is often mistaken for obtaining consent, but witnessing only attests that the person signed. If a patient asks a technician a question about the procedure, the question goes back to the provider.

A patient has an advance directive on file. What does this document primarily do?

• a.States the patient's wishes if they cannot speak✓
• b.Replaces the need for any provider orders
• c.Guarantees that the patient will refuse all treatment
• d.Authorizes the technician to decide about care

An advance directive records what treatment a patient does and does not want if they become unable to speak for themselves, and it may name a healthcare proxy to decide on their behalf. It guides the team but does not replace provider orders, and it is not a blanket refusal: many directives request full treatment. No directive gives a technician decision-making authority over a patient's care.

A technician monitoring telemetry notices a patient's rhythm has changed to a fast, abnormal pattern and the patient reports chest discomfort. What is the appropriate action?

• a.Silence the alarm and take no further action
• b.Wait until the end of the shift to report it
• c.Notify the nurse at once and stay with the patient✓
• d.Document it only, without telling anyone else

A rhythm change accompanied by chest discomfort is reported to the nurse immediately so that assessment and treatment can begin, and the technician keeps watching the patient and the monitor in the meantime. Silencing the alarm removes the warning without removing the problem, and documenting alone records an emergency that no one is responding to. The technician monitors and communicates changes but does not diagnose or treat.

When entering patient data into the electronic health record, which practice best supports accuracy and safety?

• a.Enter the data from memory several hours afterward
• b.Round the values to whatever number seems easiest
• c.Use another staff member's login for convenience
• d.Verify identifiers and review before saving✓

Accurate entry means confirming the correct patient record with two identifiers, entering measured values exactly and promptly, and re-reading the entry before it is saved. Charting from memory hours later and rounding values both introduce errors that the next clinician will treat as measurements. Every user signs in under their own credentials, because the record has to show who entered what.

A technician fails to raise the side rails as ordered, and the patient falls and is injured. This failure to provide reasonable care that a prudent technician would provide is an example of:

• a.Defamation
• b.Slander
• c.Negligence✓
• d.Assault

Negligence is the failure to provide the standard of care that a reasonably prudent person would provide, resulting in harm to the patient. Following orders and safety measures such as raising ordered side rails is part of that standard. Documentation and adherence to policy help prevent negligence and protect both patient and technician.

A technician overhears coworkers discussing a celebrity patient's diagnosis in the cafeteria. What is the ethical and legal concern here?

• a.There is no concern; staff may discuss patients here
• b.It breaches confidentiality to discuss this in public✓
• c.It is acceptable because the patient is a public figure
• d.It is only a problem if a visitor then complains

Discussing a patient's protected health information in a cafeteria breaches confidentiality and violates HIPAA whether or not anyone is listening and whether or not the patient is famous; a well-known patient is if anything at higher risk. Staff may discuss a patient only when they are involved in that patient's care and only in a private setting. The violation is the disclosure itself, not a complaint about it.HIPAA

A technician notices unexplained bruises and signs that suggest a vulnerable patient may be abused. What is the appropriate action?

• a.Ignore it unless the patient complains about someone
• b.Report what was seen to the nurse or supervisor✓
• c.Confront the person suspected of the abuse directly
• d.Wait to see whether any more bruises appear later

Healthcare workers are generally mandated reporters and must pass suspected abuse or neglect up the proper channel, usually the nurse or supervisor under facility policy, and the exact reporting duties are set by state law. The technician reports the objective observations and does not investigate or confront anyone, which could destroy evidence or put the patient at greater risk. Waiting for confirmation leaves a vulnerable patient in the situation.

When communicating with a patient who is hard of hearing but does not use sign language, which technique is most helpful?

• a.Keep your hand over your mouth while you are speaking
• b.Speak quickly to get through the explanation faster
• c.Shout loudly and directly into the patient's better ear
• d.Face the patient, speak clearly, reduce noise✓

Facing the patient lets them use lip movement and expression, speaking clearly at a normal to slightly slower pace keeps the sounds distinct, and reducing background noise removes the competition that hearing loss makes hardest to filter. Shouting is the intuitive answer and it distorts speech and raises pitch, which is usually the range already lost. Covering the mouth removes the visual cues. Making sure hearing aids are in and working, and writing things down, also help.

A technician is unsure whether a task assigned to them is within their scope. What is the appropriate first step following the chain of command?

• a.Ask a visitor in the hallway what they would do
• b.Perform the task and hope that it is allowed later
• c.Clarify with the supervising nurse before acting✓
• d.Refuse the task and say nothing to anyone

When a technician is unsure whether an assigned task is within scope, the chain of command says to ask the supervising nurse before doing anything. Performing first and asking later risks patient harm and the technician's certification, and silently refusing leaves the task undone with no one aware that it still needs to be covered. Asking for clarification is a mark of professional accountability rather than a failure.

Under the HIPAA 'minimum necessary' principle, how should a technician access and share patient information?

• a.Only the information needed for the specific job task✓
• b.Share full records with anyone who asks for them
• c.Access all records freely, out of curiosity
• d.Post updates on social media for the family

The HIPAA minimum necessary standard limits both access and disclosure to the protected health information actually required for the task at hand. It applies to reading as well as to sharing, so opening a record out of curiosity is a violation even if nothing is repeated. Limiting access protects the patient and reduces the number of records exposed in any single breach.HIPAA

After a patient falls, in addition to notifying the nurse, the technician should complete which document?

• a.A personal note kept at home for later reference
• b.A short account posted on the unit's social media
• c.An incident report documenting the facts✓
• d.Nothing further, since the nurse handles all of it

An incident or occurrence report is completed after an event such as a fall, recording the facts, the actions taken, and the patient's condition objectively and without opinion or blame. It is used for risk management and quality improvement and is kept separate from the medical record; the clinical facts of the fall are also charted in the record itself. Personal notes and anything posted publicly create privacy exposure and are never a substitute.

A technician records a rectal temperature of 100.4°F on an adult patient. How does a rectal reading typically compare with an oral reading taken on the same patient?

• a.It runs about 1°F lower, because the probe sits away from the body core
• b.It matches the oral reading, so the site does not have to be charted
• c.It runs about 1°F higher than the oral reading at the same moment✓
• d.It runs about 2°F lower and is charted as an axillary value

Rectal temperature is measured closest to the body core, and it reads roughly 1°F above an oral reading taken at the same time, so 100.4°F rectally corresponds to about 99.4°F by mouth. Axillary is the site that reads about 1°F below oral, which is why the answer that reverses the offset and the answer that shifts it to 2°F both describe the wrong site. Sites are not interchangeable, so the route must be documented beside the value or the next reading cannot be compared with this one. A technician reports the number and the site and lets the nurse interpret the difference.

A patient cannot hold a probe in the mouth, and the technician is directed to use the axillary route. Which statement about that site is correct?

• a.It reads about 1°F above the oral route and is the preferred adult site
• b.It reads the same as the tympanic route and needs no site notation
• c.It reads about 1°F below the oral route and is the least accurate site✓
• d.It reads about 1°F below the rectal route and suits confused patients

The axilla is a surface site with no enclosed cavity, so it reads roughly 1°F below the same patient's oral temperature and is considered the least accurate of the common routes. Raising rather than lowering the offset inverts the relationship; the rectal route is the one that reads above oral. Axillary sits about 2°F below rectal, not 1°F, so the answer pairing it with the rectal route understates the gap. The probe must stay in skin-to-skin contact with the arm held down against the chest for the full measuring time, and the site is charted with the value.

A patient finishes a glass of ice water just as the technician arrives to take an oral temperature. What should the technician do?

• a.Take the reading now and note that the patient drank cold water first
• b.Wait about 15 minutes before placing the probe under the tongue✓
• c.Take the reading now and add one degree to the recorded result
• d.Switch to the axillary route because the mouth is now unusable

Cold or hot fluids, smoking, and chewing gum change the temperature of the oral cavity, so an oral reading taken immediately is not a measure of the patient. Waiting about 15 minutes lets the mouth return to body temperature and gives a value that can be trusted and trended. Charting the reading with a note about the ice water still leaves an inaccurate number in the record, and adding a fixed degree invents a correction that no one can verify. Switching sites is unnecessary here because the mouth becomes usable again after a short wait, and a changed site would break the comparison with earlier oral readings.

A technician is taking a tympanic temperature on a 40-year-old patient. How should the ear be handled before the probe is inserted?

• a.Pull the outer ear straight down before inserting
• b.Pull the outer ear up and back to straighten the canal✓
• c.Leave the ear untouched and insert the probe gently
• d.Pull the outer ear down and back before inserting the probe

An adult ear canal curves, so the pinna is pulled up and back to straighten it and aim the sensor at the tympanic membrane instead of the canal wall. Pulling down and back is the maneuver used on a child under about three years old; on an adult it tilts the probe away from the membrane and tends to read low. Pulling straight down does not open the adult canal either. Inserting the probe without repositioning the ear risks an off-target reading and discomfort. Probe depth and technique vary by device, so the manufacturer's instructions for the thermometer in use govern the details.

After counting a patient's radial pulse, the technician needs a respiratory rate. Which technique gives the most accurate count?

• a.Explain that breathing will now be counted, then watch the chest for a full minute
• b.Ask the patient to count breaths aloud so the two totals can be compared
• c.Place a hand on the abdomen and say that breathing is being counted
• d.Keep the fingers on the wrist as if still taking the pulse and count chest rises✓

Breathing is partly under voluntary control, so a patient who knows the breaths are being counted will usually slow down, speed up, or breathe more deeply. Leaving the fingers on the radial site after the pulse count keeps the patient unaware and yields a natural rate; one rise and one fall together count as one respiration. Announcing the count, whether by explaining it first or by placing a hand on the abdomen and saying so, produces the very change the technique is designed to avoid. Having the patient count aloud makes the problem worse, because speaking itself alters the breathing pattern.

A nurse asks a technician to help obtain a pulse deficit on a patient with an irregular heartbeat. How is that measurement made?

• a.One person counts the radial pulse twice and averages the two totals
• b.One person counts the apical rate, then the radial rate an hour later
• c.Two people count the radial pulse at both wrists and add the counts
• d.Two people count the apical and radial rates at once, and the radial is subtracted✓

A pulse deficit is the difference between the heart rate heard at the apex and the rate felt at the radial artery, and it exists because some contractions are too weak to send a palpable wave to the wrist. Both rates must be counted during the same full minute, which normally takes two people and one shared start signal; the radial count is then subtracted from the apical count. Counting the two sites an hour apart compares different minutes and can only produce a meaningless number. Averaging radial counts or adding the two wrists never involves the apical rate, so no deficit can be derived from either.

A technician counts an apical rate of 44 beats per minute on an adult whose rate has been in the 70s and who now says the room is spinning. What should the technician do?

• a.Chart the rate, finish the remaining vital signs, and hand off at shift change
• b.Report the rate to the nurse or supervisor before leaving the bedside✓
• c.Recount for a full minute and chart the lower of the two counts
• d.Chart the rate and recheck it at the next scheduled round of vital signs

An adult resting pulse below 60 beats per minute is outside the 60 to 100 range, and 44 beats per minute together with new dizziness is a finding that has to reach a licensed nurse immediately rather than sit in a chart. Charting is documentation; escalating is communication, and an abnormal value paired with a symptom requires both, in that order of urgency. Recounting for accuracy is reasonable practice, and it is the strongest wrong answer here, but confirming a number the technician already believes must not delay the report, and charting the lower of two counts is not a real verification rule. Waiting for the next round or for shift change leaves a symptomatic patient unmonitored.

A technician documents that a patient's radial pulse feels thready. Which description matches that term?

• a.A pulse that feels strong and full and bounds against the fingertips
• b.A pulse that is weak and rapid and disappears under light pressure✓
• c.A pulse that can be felt only with a stethoscope at the apex
• d.A pulse that alternates between strong and weak beats in a regular pattern

Thready describes pulse quality, not rate or rhythm: the wave is weak and often rapid, feels thin under the fingers, and is easily obliterated by slight pressure, which is why it is commonly seen with low blood volume or poor perfusion. A strong, full, forceful wave that pushes back against the fingertips is called bounding, the opposite quality. A pulse audible only at the apex describes a site, and a regular alternation of strong and weak beats describes a distinct finding rather than thready quality. Quality is charted alongside the rate, and a newly thready pulse is reported to the nurse.

A patient returns from surgery with a cast on the right lower leg, and the nurse asks the technician to check circulation to that foot. Which pulse site is used?

• a.The dorsalis pedis pulse on the top of the affected foot✓
• b.The brachial pulse at the inner bend of the elbow on that side
• c.The carotid pulse at the side of the neck, counted for a full minute
• d.The apical pulse heard over the left side of the chest

Circulation below a cast is checked at a pulse site distal to the injury, and the dorsalis pedis on the dorsum of the foot is the standard pedal site; the posterior tibial behind the medial ankle is the usual alternative. The site is often marked so that every shift palpates the same spot, and it is compared with the other foot for strength, color, warmth, and capillary refill. The brachial site lies in the arm and reports nothing about a leg. The carotid and apical sites measure how fast the heart is beating overall, which can be perfectly normal while blood flow past a tight cast is compromised.

A technician cannot palpate a radial pulse on an adult who is pale, cool, and barely responsive. Which action is correct?

• a.Palpate both carotid arteries at the same time to compare the sides
• b.Rub the carotid area firmly until a pulse becomes easy to feel
• c.Palpate one carotid artery gently and get help for the patient right away✓
• d.Wait ten minutes and try the radial site on the other wrist

When peripheral perfusion drops, the carotid is the last pulse to be lost, so it is the site checked on an adult who is pale and barely responsive. Only one side is palpated, with light pressure, because compressing both carotids at once can reduce blood flow to the brain, and firm rubbing over the artery can slow the heart further. A patient in that condition needs immediate help at the same time the pulse is being assessed, not a ten-minute wait; the other wrist will be just as difficult to palpate if perfusion is poor. The technician stays with the patient and calls out for the nurse rather than leaving the room to look for one.

A technician is applying a manual blood pressure cuff to an adult's upper arm. Where do the cuff bladder and the stethoscope belong?

• a.The bladder over the outer arm, with the stethoscope at the radial artery of the wrist
• b.The bladder centered over the brachial artery, about 1 inch above the elbow crease✓
• c.The bladder over the brachial artery, with the lower edge touching the elbow crease
• d.The bladder over the inner arm, with the stethoscope tucked under the cuff edge

The bladder is centered over the brachial artery on the inner aspect of the upper arm, and its lower edge sits roughly 1 inch above the antecubital crease so the stethoscope can rest flat on the artery without touching the cuff. Bringing the lower edge down to the crease is the closest wrong answer, because the diaphragm then has no clear skin to sit on and rubs the cuff, adding noise that mimics or masks Korotkoff sounds. Tucking the diaphragm under the cuff produces the same artifact. Listening at the radial artery is wrong for auscultation; the wrist is used for palpating a systolic estimate, not for hearing sounds.

A patient has an arteriovenous fistula for dialysis in the left arm and an IV infusing in the right arm. The technician is asked for a blood pressure. What should the technician do?

• a.Use the left arm, because a fistula is not affected by cuff pressure
• b.Ask the supervisor or nurse which site to use, since both arms are restricted✓
• c.Use the right arm and pause the IV pump while the cuff inflates
• d.Use a wrist cuff on the fistula side and chart the site used

A cuff is not applied over a dialysis access, an arm on the side of a mastectomy with lymph node removal, an arm with an infusing IV, or an injured limb, and this patient has a restriction on each side. When every usual site is excluded, the technician does not improvise a site; the nurse or supervisor decides whether a thigh or forearm measurement is appropriate under facility policy. Inflating over a fistula can damage the access the patient depends on for dialysis, and a wrist cuff on that same arm still compresses the limb. Stopping an infusion to free the other arm changes the patient's therapy, which is outside the technician's scope.

A technician uses a standard adult cuff on a patient whose upper arm is far larger than the cuff bladder. How does the mismatch affect the reading?

• a.It produces a falsely low reading, because a small bladder under-compresses
• b.It produces a falsely low diastolic number with an accurate systolic value
• c.It has little effect if the arm is supported at heart level
• d.It produces a falsely high reading of both the systolic and diastolic✓

A cuff that is too narrow or too short for the arm must be pumped to a higher pressure before it compresses the brachial artery, so both numbers come out higher than the patient's true pressure; a cuff that is too large has the opposite effect and reads low. The bladder width should cover roughly 40 percent of the arm circumference and its length should wrap about 80 percent of the way around. Assigning the error to the diastolic alone is wrong, since the whole compression curve shifts. Supporting the arm at heart level is good technique but does not correct a sizing error, and mis-sizing is the most common reason a patient is labeled hypertensive in error.

A technician takes a blood pressure while the patient's arm hangs unsupported at the side, well below heart level. What effect does that arm position have on the result?

• a.Gravity makes both numbers come out low
• b.The numbers come out falsely high✓
• c.The systolic falls but the diastolic holds
• d.Only the diastolic number is affected

Hydrostatic pressure adds to the measured pressure when the cuff sits below the level of the heart, so a dependent arm raises both the systolic and the diastolic, often by several mm Hg for every inch of drop. An arm held above heart level does the reverse and reads low, which is the misconception behind the answer that blames gravity for a low result. Holding the arm up without support adds isometric muscle work, another source of error. Correct technique seats the patient with feet flat, back supported, and the mid-arm resting at the level of the heart, and both numbers are affected together rather than one alone.

While inflating the cuff, a technician palpates the radial pulse and finds that it disappears at 130 mm Hg. To what pressure should the cuff then be inflated for the auscultated reading?

• a.To 130 mm Hg, which is the point where the pulse disappeared
• b.To about 160 mm Hg, or 30 mm Hg above that point✓
• c.To 200 mm Hg for an adult, then deflate slowly
• d.To about 145 mm Hg, which is 15 mm Hg above that point

The palpated systolic estimate tells the technician where the sounds will begin, and the cuff is inflated about 30 mm Hg above that point so the first Korotkoff sound is not missed and an auscultatory gap cannot be mistaken for the systolic. Here 130 plus 30 gives 160 mm Hg. Stopping at the palpated point or only 15 mm Hg above it risks starting to listen after the true first sound, particularly in an older patient with a wide gap. Routinely pumping every adult to 200 mm Hg is unnecessarily uncomfortable and can itself alter the reading, which is why the palpated estimate is obtained first.

Deflating the cuff on an adult, a technician hears clear tapping begin at 138 mm Hg, the sounds become muffled at 112 mm Hg, and all sound disappear at 86 mm Hg. What is recorded?

• a.112/86 mm Hg, taking the midpoint of the sounds as the systolic
• b.138/86 mm Hg, the first clear tapping over the last sound✓
• c.138/112 mm Hg, taking the muffling point as the true diastolic
• d.86/138 mm Hg, with the diastolic written first

The first clear tapping heard as the cuff deflates is Korotkoff phase I and marks the systolic pressure, and in adults the point where sound disappears, phase V, is charted as the diastolic, giving 138/86 mm Hg. Muffling is phase IV, and using it as the diastolic is the strongest wrong answer because phase IV is in fact used in some pediatric measurement and is recorded as a third number when the gap between muffling and disappearance is wide. Treating the muffling point as a systolic ignores the sounds already heard at 138 mm Hg. Blood pressure is always written systolic over diastolic, so reversing the two numbers misreports the value.

A technician records 44 breaths per minute and a pulse of 138 beats per minute on a 2-day-old newborn who is sleeping quietly. How should these values be handled?

• a.Report both values, because a rate above 20 breaths is too fast
• b.Report the pulse alone, because 138 exceeds the adult upper limit
• c.Recount both values after waking the newborn for accuracy
• d.Chart both values, which fall inside the expected ranges for a newborn✓

A newborn breathes roughly 30 to 60 times a minute and carries a pulse of roughly 100 to 160 beats per minute, so 44 and 138 are both ordinary findings in a quiet infant and are simply charted. Applying adult limits of 12 to 20 breaths and 60 to 100 beats is the classic error, and it generates false alarms that pull a nurse away from a patient who needs one. Vital signs are counted for a full minute in an infant because the rhythm is normally irregular. Waking the newborn would raise both rates and give a less useful baseline than the resting values already obtained.

A technician counts an apical pulse of 118 beats per minute on a calm, playing 2-year-old. Which interpretation is correct?

• a.It is above normal, since 100 is the upper limit at any age
• b.It should be rechecked, because a toddler's rate rarely passes 90
• c.It falls inside the range expected for a toddler and is charted as such✓
• d.It is too slow for a 2-year-old and should be reported

A toddler's resting heart rate runs roughly 90 to 140 beats per minute, well above the adult range, so 118 in a calm 2-year-old is an expected finding rather than tachycardia. Heart rate falls gradually with age, and only in adolescence does it approach the adult 60 to 100 range, which is why treating 100 as a ceiling at every age produces unnecessary reports. Ninety is near the lower edge of the toddler range, not a maximum, so a recheck for a rate above it is not indicated. Calling 118 slow inverts the relationship between age and heart rate entirely.

A pulse oximeter on the index finger reads 86 percent for a patient who is alert, speaking in full sentences, and breathing 16 times a minute. The hand is cold and the nails carry dark polish. What should the technician do first?

• a.Report the 86 percent to the nurse or supervisor and chart it as a true value
• b.Warm the hand and move the probe to a clean, polish-free finger✓
• c.Start oxygen at 2 liters per minute and recheck in ten minutes
• d.Chart 86 percent and recheck it on the next round of vitals

A pulse oximeter reads the percentage of hemoglobin saturated with oxygen by shining light through tissue, so a cold, poorly perfused finger, dark nail polish, motion, or a loose probe all corrupt the signal. When the number contradicts a patient who is alert and speaking comfortably at 16 breaths a minute, the technique is corrected first: warm the hand, remove the polish or use an unpolished digit, an earlobe, or a toe, then read again. Charting or reporting an artifact as a true value passes bad data to the nurse and can trigger an unneeded intervention. Starting or titrating oxygen is outside the technician's scope, and a saturation that stays low after the probe is corrected is reported immediately.

A technician wraps an automatic cuff over a patient's thick sweater sleeve, using the only cuff on the cart that will fasten over the bulky sleeve. The machine reports 156/94 mm Hg for a patient whose readings have all been near 120/70. What should the technician do first?

• a.Chart 156/94 now and tell the supervisor the pressure has climbed sharply
• b.Wait ten minutes and repeat the reading over the sleeve
• c.Repeat the measurement on the bare arm with a properly sized cuff✓
• d.Let the patient rest quietly for an hour and recheck

Bulky clothing under a cuff keeps the bladder from lying flat against the artery and typically inflates the result, so this number describes the technique rather than the patient. A value obtained with faulty technique is repeated correctly before it is charted or passed on, since reporting it as a real change can prompt a medication decision built on an artifact: the arm is bared and a cuff whose bladder fits that arm is used. Waiting ten minutes or an hour and measuring over the sleeve again repeats the same error and reproduces the same inflated result. If the corrected reading is still 156/94 it is charted and reported, and under the 2017 ACC and AHA thresholds a reading at or above 140/90 mm Hg falls in the stage 2 category, with any diagnosis resting on the provider's review of repeated measurements.

A patient with advanced dementia cannot report pain in words. During morning care the patient grimaces, moans, and guards the right hip whenever it is moved. What should the technician do?

• a.Record that the patient denies pain, since no number was given
• b.Ask the patient to rate the pain from zero to ten until an answer comes
• c.Document the specific behaviors observed and report them to the nurse✓
• d.Wait for the next shift to try the pain scale again

Pain is treated as the fifth vital sign, and a patient who cannot self-report is assessed through behavior: facial grimacing, moaning or crying out, guarding or bracing a body part, restlessness, and changes in appetite or sleep. The technician charts what was seen and what triggered it, in objective terms, and reports it so the nurse can complete an assessment. Recording that the patient denies pain is a false entry, because no denial was made, and absence of a number is not absence of pain. Repeating a numeric scale the patient cannot use, or postponing the concern to another shift, leaves observed pain untreated.

A patient who is laughing with visitors rates the pain as 8 on a 0-to-10 scale when the technician asks. What pain score should be charted and passed on?

• a.A 3, to match how comfortable the patient appears
• b.No pain, since the patient is laughing with guests
• c.The 8 exactly as the patient reported it✓
• d.An 8, with a note that the patient may be exaggerating

A numeric pain rating is a self-report measurement, and the value charted is the number the patient states; behavior is not a substitute for it, because people distract themselves from pain with conversation, laughter, and visitors. Substituting a lower number, or charting no pain at all, alters a vital sign to match an observation and can delay treatment. Adding a comment that the patient may be exaggerating is the closest wrong answer, since it does preserve the 8, but it inserts a judgment the technician is not licensed to make and colors how the nurse reads the record. Objective observations, such as the patient laughing and moving freely, may be charted separately as observations.

A patient weighs 165 pounds. Using the conversion 1 kg equals 2.2 lb, what weight should the technician record in kilograms?

• a.363 kg
• b.75 kg✓
• c.82.5 kg
• d.165 kg

Pounds are converted to kilograms by dividing by 2.2, so 165 divided by 2.2 equals 75 kg. Multiplying instead of dividing gives 165 times 2.2, or 363 kg, a weight no adult carries, which is why the direction of the operation should be sanity-checked against the fact that a kilogram is heavier than a pound. Dividing by 2 rather than 2.2 gives 82.5 kg, a small enough error to slip through and large enough to matter when a weight-based dose is calculated from it. Recording the same number in both units treats the units as equal and more than doubles the true value.

A patient on daily weights measured 168 lb yesterday and 173 lb this morning, on the same scale, at the same hour, in the same gown. What should the technician do?

• a.Chart 173 lb and note that daily weights vary by a few pounds
• b.Chart yesterday's weight again, since a 5 lb gain overnight is impossible
• c.Chart 173 lb and report the 5 lb overnight gain to the nurse or supervisor✓
• d.Reweigh the patient after breakfast and chart the lower number

Daily weights exist to reveal a trend, and because a liter of retained fluid weighs about 2.2 lb, a 5 lb gain in 24 hours points to roughly 2 liters of fluid rather than to body mass; that pattern matters in heart failure, kidney disease, and any patient on a fluid restriction. The conditions described rule out the usual technical explanations, so the value is charted and the change is reported the same shift instead of being left in the record for someone to notice later. Dismissing the jump as normal variation, or copying forward yesterday's number, destroys the trend the measurement was ordered to capture. Reweighing after a meal adds the weight of food and fluid and biases the comparison further.

A technician is giving a complete bed bath and starts with the patient's face. How should the eyes be washed?

• a.From the inner corner outward, with a clean area of the cloth for each eye✓
• b.From the outer corner inward, using the same soapy corner of the cloth for both eyes
• c.With mild soap lathered over the closed lids, then rinsed and patted dry
• d.With a cotton ball moistened in the basin water used later for the perineum

The eyes are washed with plain water from the inner canthus toward the outer canthus, and a different part of the washcloth is used for the second eye, so that drainage and organisms are not carried into the tear duct or across to the other eye. Wiping toward the nose pushes debris into the duct, and reusing the same soiled corner of the cloth carries organisms from one eye to the other. Soap stings and dries the lids and is not used on the eyes. Water that will later be used for the perineal area is the most contaminated water on the tray and is never the water an eye is washed with.

A technician is shaving a patient's face with a safety razor after softening the beard with a warm, moist towel. Which technique is correct?

• a.Hold the skin taut and shave in the direction the hair grows✓
• b.Shave against the direction of growth to leave the skin smoother for longer
• c.Apply the razor to dry skin without soap so the strokes are easier to see
• d.Let the skin stay loose and use long strokes without rinsing the blade

Holding the skin taut gives a flat surface and shaving with the grain reduces nicks, razor burn, and ingrown hairs, which matters most in a patient who bleeds easily or takes an anticoagulant. Shaving against the grain does cut closer, which is why candidates pick it, but it lifts and cuts the hair below the skin line and irritates the follicle. A dry shave without lather drags on the skin and abrades it. Loose skin folds into the blade, and a blade clogged with hair and lather pulls rather than cuts.

A technician is giving foot care to a patient who has diabetes. Which action is appropriate?

• a.Dry gently between the toes and leave nail cutting to the nurse✓
• b.Trim the toenails straight across with clippers once they have softened
• c.Soak the feet in hot water for 20 minutes to loosen thickened calluses
• d.Rub a thick layer of lotion between the toes to keep the skin from cracking

Diabetes brings reduced sensation and reduced circulation, so a small cut heals poorly and can become a serious infection; most facilities restrict nail cutting for these patients to a nurse or podiatrist, and the technician's job is washing, careful drying, and inspecting for redness, cracks, or breaks in the skin. Straight-across trimming is the right technique in general, which is what makes it tempting here, but the restriction is on who cuts the nails, not on how. Hot soaks are a burn risk in a foot with neuropathy and also macerate the skin. Lotion is applied to the tops and soles but not between the toes, where trapped moisture promotes skin breakdown and fungal growth.

A patient has an intravenous line running in the left arm and needs a clean gown put on. How should the technician manage the sleeve on that side?

• a.Slide the right arm in first and drape the gown loosely over the left shoulder
• b.Disconnect the tubing at the hub, dress the left arm, then reconnect the line
• c.Have the patient hold the bag below the arm while the sleeve is pulled up
• d.Pass the bag and tubing through the sleeve first, then the left arm✓

The affected side is dressed first: the technician takes the sleeve of the clean gown, passes the IV bag and tubing through it from the inside out, rehangs the bag, and then guides the arm into the sleeve, so the line is never pulled or disconnected. Dressing the free arm first and leaving the IV side draped is a common shortcut but leaves the patient uncovered and the line unsupported. Disconnecting the tubing breaks a closed sterile system and is outside the technician's scope. Lowering the bag below the insertion site allows blood to back up into the tubing.

A technician finds a patient lying on linens that are soaked with urine. What should the technician do first?

• a.Ask the supervisor whether an incontinence brief may be started
• b.Wash and dry the skin, then put on dry linens and clothing✓
• c.Spread barrier cream over the wet skin and recheck in an hour
• d.Chart the episode and finish the morning rounds

Urine on the skin raises the surface pH and softens the stratum corneum, and pressure or friction on wet, macerated skin causes breakdown within hours, so the first action is to clean the skin with a mild cleanser, dry it thoroughly, and replace the wet linen and clothing. Barrier products belong on skin that is already clean and dry; applying them over wet skin seals the moisture in. Asking about a brief is a reasonable conversation later, but it is not what the patient needs while lying in urine. Documenting the episode is required, and so is telling the nurse about any redness found, but neither comes before getting the patient clean and dry.

A technician is shampooing the hair of a patient who must remain in bed. Which action is part of the correct procedure?

• a.Put a shampoo trough under the head and cover the eyes with a washcloth✓
• b.Raise the head of the bed as high as it goes so the water drains toward the back
• c.Use water as hot as the patient can tolerate to help loosen scalp oil and flakes
• d.Comb the hair only after it dries fully so that the wet strands do not break off

A shampoo trough or inflatable basin channels the water into a collection container and keeps the bed dry, and a folded washcloth over the eyes keeps shampoo and water out of them. Raising the head of the bed sends water down the neck and back instead of into the trough; the head is supported and slightly extended over the trough with the bed flat or nearly flat. Water temperature is checked the same way as for a bath, at about 105°F, since a patient with reduced sensation can be scalded before saying so. Wet hair is combed out from the ends upward while it is still damp, because dried tangles are harder on the hair and the scalp.

A technician takes a patient's dentures to the sink to clean them. Which action protects the dentures from damage?

• a.Line the sink with a towel and run a little water in it before starting✓
• b.Rinse and then store the dentures in hot water so that the heat kills bacteria
• c.Scrub the dentures with abrasive scouring powder to lift stains
• d.Wrap the dentures in a dry paper towel at the bedside between meals

Dentures are slippery when wet and crack or chip easily, so the sink is padded with a towel and partly filled with water to cushion a drop, and they are held firmly over that surface while being brushed. Hot water warps the acrylic base and changes the fit, so cool or tepid water is used for both cleaning and storage. Abrasive powders scratch the surface, and the scratches then collect stain and organisms. Dentures left in a dry paper towel dry out, warp, and are thrown away with the trash more often than any other patient belonging; they belong in a labeled denture cup with water or solution.

A patient's family asks a technician to take out the patient's indwelling urinary catheter because it is uncomfortable. What is the appropriate response?

• a.Report the request to the nurse or supervisor, since removal needs an order✓
• b.Remove the catheter after deflating the balloon, because the patient is uncomfortable
• c.Clamp the drainage tubing for an hour and see whether the discomfort settles down
• d.Tell the family that only a physician may take out a catheter at the bedside

Discontinuing an indwelling catheter requires a provider's order; whether a technician may then perform the removal depends on state rules, facility policy, and the certification held, so the request goes to the nurse or supervisor rather than being acted on at the bedside. Deflating the balloon and pulling the catheter on a family's request removes a device that no one has ordered discontinued. Clamping the tubing obstructs drainage, raises the risk of infection and bladder distention, and is not done without an order. Saying that a physician must do it is wrong on the facts, because in many facilities a nurse, or a technician under policy, carries out the removal once it is ordered.

While changing an ostomy pouch, a technician sees that the stoma, pink and moist the day before, now looks dusky purple. What should the technician do?

• a.Apply the new pouch and note the color change in the chart at the end of the shift
• b.Rub the stoma gently with a warm cloth to bring the circulation back
• c.Stop and report the color change to the nurse or supervisor before going on✓
• d.Leave the pouch off and cover the stoma with a dry gauze square

A healthy stoma is beefy red or pink and moist; a dusky, purple, or black stoma suggests that its blood supply is compromised, which is an urgent finding and is reported immediately rather than at the end of the shift. Finishing the pouch change and charting it later is the trap, because the pouch change itself is a normal technician task and the color is easy to write off as bruising. Rubbing the stoma will not restore perfusion and can injure the fragile mucosa, which bleeds readily. Leaving the stoma open under gauze lets output soil the skin and the bed and does nothing about the cause.

A technician is teaching a patient how to collect a clean-catch midstream urine specimen. Which instruction is correct?

• a.Cleanse first, void briefly into the toilet, then collect the middle of the stream✓
• b.Void the first portion into the cup and the rest of the stream into the toilet
• c.Collect the entire voiding in the sterile cup from start to finish
• d.Wipe with plain dry tissue and collect the last drops of the voiding

Only the middle portion of the stream is kept. The first portion flushes organisms out of the distal urethra and the perineum into the toilet, which is what makes the specimen usable for culture, and cleansing with the supplied antiseptic wipes comes before any of it. Catching the first portion gathers exactly the contamination the technique is designed to wash away. A complete voiding is what a routine or a timed collection wants, not a midstream culture specimen. Plain dry tissue does not clean the meatal area, and the last drops are the smallest and least useful part of the voiding.

A 24-hour urine collection is ordered to begin at 0700. How should the collection be started and ended?

• a.Discard the 0700 voiding and note the start time, then save all urine through 0700 the next day✓
• b.Save the 0700 voiding as the first specimen and stop collecting at 0700 the next morning
• c.Start saving urine after breakfast and end the collection at bedtime on the same day
• d.Save only the first and the last voiding of the 24 hours and discard everything between

The bladder has to be empty when the clock starts, so the voiding at the start time is discarded, the time is recorded, and every voiding afterward is saved, including one final voiding at the end of the 24 hours. Saving the first voiding adds urine the kidneys produced before the collection period and makes the result too high. A collection that runs from after breakfast to bedtime is not 24 hours and misses the overnight portion entirely. Saving only two voidings loses the rest of the period, and if any voiding is discarded by accident the whole collection is restarted.

A technician is collecting a stool specimen from a patient who uses the bathroom. Which action keeps the specimen usable?

• a.Collect the sample out of the toilet bowl water after the patient has flushed once
• b.Have the patient pass urine and stool into the container together
• c.Wrap the specimen in toilet tissue before it is placed into the container
• d.Have the patient void first, then pass the stool into a clean collection hat✓

Urine, toilet water, and toilet paper all invalidate a stool specimen, so the patient voids first, the bladder is empty, and the stool is passed into a clean collection container or a hat set in the toilet and then transferred with the tongue blade in the kit. Bowl water dilutes the sample and adds organisms and disinfectant residue. Urine mixed into the container is the single most common reason a stool specimen is rejected. Toilet tissue absorbs the specimen and introduces fibers and chemicals that interfere with occult blood and culture testing.

A patient receiving a continuous tube feeding tells the technician that he feels nauseated, and the feeding pump is alarming. What should the technician do?

• a.Leave the pump settings alone, keep the head of the bed up, and report both to the supervisor✓
• b.Turn the feeding rate down until the nausea settles and mention it at the next rounds
• c.Stop the pump, lay the head of the bed flat, and offer the patient small sips of water
• d.Silence the alarm and flush the tube with warm water to clear the obstruction

Rate changes, tube flushes, and troubleshooting a feeding pump belong to licensed staff; the technician keeps the patient safe by leaving the settings untouched, maintaining the elevated head of the bed that protects against aspiration, and reporting the nausea and the alarm right away. Turning the rate down is an adjustment to a therapy the technician did not order and cannot order. Lying the patient flat while formula is in the stomach increases the aspiration risk, and oral fluids are not given to a patient whose tolerance is in question. Flushing the tube assumes an obstruction that has not been confirmed and is a licensed task in most facilities.

A patient has an order for a clear liquid diet. Which tray item is consistent with that order?

• a.A bowl of cream of chicken soup, which is thin enough to pour
• b.A half pint of skim milk, since the fat has been taken out of it
• c.Plain gelatin with a cup of beef broth and a glass of apple juice✓
• d.A carton of orange juice with pulp and a cup of hot cocoa

A clear liquid diet is made up of items that are liquid at body temperature and that a light can be seen through, such as clear broth, plain gelatin, tea, black coffee, ice pops without pulp, and clear juices like apple or white grape. Cream soup is the closest distractor because it pours like a liquid, but the dairy and the puree make it opaque and put it on the full liquid diet instead. Milk is likewise a full liquid, not a clear one. Pulp makes orange juice opaque, and cocoa is a milk drink.

A tray arrives for a patient whose diet order reads pureed. Checking the tray against the order, which item should the technician question before it is served?

• a.Pureed peaches served in a dish beside the main course
• b.A soft dinner roll with butter set on the side of the plate✓
• c.Whipped potatoes blended smooth with a little warm gravy over them
• d.Strained cream soup thickened to a smooth and lump-free consistency

A pureed diet is limited to foods blended to a smooth, pudding-like texture that need no chewing, which is why it is ordered for patients with dysphagia or with no ability to chew. A dinner roll keeps its bread texture, forms a bolus in the mouth, and does not belong on the tray, so the technician holds it and checks the order with the nurse rather than serving it. Pureed fruit, smooth whipped potatoes, and strained thickened soup all meet the texture requirement. Comparing the diet card with the order on every tray before it reaches the patient is part of the technician's routine, and the same check catches salt on a low-sodium tray.

A technician is restocking a supply cart when a call light comes on and the patient states over the intercom that she needs the urinal now. What should the technician do?

• a.Ask the supervisor which of the waiting call lights should be taken first
• b.Finish restocking the cart and answer the light on the way back down
• c.Tell her over the intercom that someone will come soon
• d.Go to the room now, screen the patient, and hand her the urinal✓

A call light is answered promptly, and a request to void is answered promptly for a reason beyond courtesy: a patient who waits is the patient who climbs over the rail unassisted, and falls and incontinence episodes both track with slow call light response. Restocking a cart is not time-critical and waits. Telling the patient over the intercom to wait leaves her alone with the same choice between waiting and getting up. Asking the supervisor how to prioritize turns a task the technician can complete in under a minute into a delay, and the supervisor is not the person holding the urinal.

A patient is on a 1,200 mL daily fluid restriction and tells the technician that his mouth feels dry. Which action is appropriate?

• a.Fill the water pitcher as usual and record whatever the patient drinks
• b.Hold all fluids until the provider reviews the restriction in the morning
• c.Offer a large glass of water now and give nothing more this evening
• d.Give frequent mouth care and space the allowed fluid across the three shifts✓

The allowance is divided across the day, commonly with the largest share on the day shift and the smallest overnight, and dry mouth is managed with frequent oral care, lip moisturizer, and rinses that are not swallowed, so the patient is comfortable without exceeding the limit. Leaving a full pitcher at the bedside makes it nearly impossible to keep the total at 1,200 mL. Withholding fluids altogether is not what the order says and pushes the patient toward dehydration. Giving a large glass at once uses up much of the day's allowance in a single serving and leaves nothing for the hours that follow.

Which set of findings should a technician report as possible dehydration?

• a.A bounding pulse, moist skin, and urine that is pale and nearly colorless
• b.Dark scant urine, a dry mouth, and skin that tents when pinched✓
• c.Puffy ankles, a moist cough, and a weight gain of 2 pounds since yesterday
• d.Warm flushed cheeks, a full pulse, and frequent large voidings

Fluid loss concentrates the urine so it turns dark and small in amount, dries the mucous membranes, and reduces skin elasticity, so a pinched fold over the sternum or forearm stays tented instead of falling back; a rapid weak pulse and sudden weight loss go with the same picture. Puffy ankles with a moist cough and an overnight weight gain point the other way, toward fluid overload, and that pairing is the one candidates most often confuse with dehydration because both are fluid problems that must be reported. Pale, plentiful urine with moist skin is the picture of adequate hydration. Frequent large voidings are not a sign of fluid deficit.

A patient eats about half of the solid food on the lunch tray and drinks part of the beverage. How should the technician record the meal?

• a.Record the meal as refused, since the tray came back unfinished
• b.Record the percentage of the meal eaten and enter fluids in mL on the I&O sheet✓
• c.Record the weight of the food left on the tray in the intake column
• d.Record half of the tray's calorie count in the intake total for the shift

Meal intake is charted as the portion of the served food consumed, usually as a percentage or in fourths, while liquids are measured separately in milliliters on the intake and output record, since only fluids belong in the I&O total. Charting the meal as refused is inaccurate and can trigger a nutrition consult the patient does not need. Leftover food is not weighed on a routine tray, and weight is not what the intake column asks for. Calorie counts are calculated by dietary staff from the recorded portions, not estimated by the technician at the bedside.

A patient on strict intake and output finishes a 240 mL cup that was filled with ice chips. How much intake should be recorded?

• a.240 mL, because the cup held that volume when it was filled
• b.480 mL, since melting roughly doubles the volume of the chips
• c.0 mL, because ice chips are counted as a solid on the record
• d.120 mL, because ice chips are recorded as about half their volume✓

Ice chips do not fill a container completely; air occupies the spaces between them, so the melted volume is about half the volume of the cup, and 240 mL of chips is charted as roughly 120 mL. Recording the full 240 mL is the most common error and overstates intake by about double. Melting does not increase volume, so a figure above the cup size cannot be right. Ice chips are fluid once melted and are counted on the intake side rather than ignored.

At the end of the shift a technician empties a patient's urinary drainage bag. Which action is correct?

• a.Rest the drain spout on the rim of the graduate to hold the stream steady
• b.Use a graduate kept for that patient and keep the spout from touching it✓
• c.Take the bag off the catheter tubing so that it can drain completely
• d.Empty the bag into the toilet and estimate the amount for the record

Each patient has a dedicated graduated container, and the drain spout is wiped, opened without contact with the graduate or the floor, and re-clamped and wiped again afterward, which keeps organisms from traveling up the spout into a closed system. Letting the spout rest on the rim contaminates it against the very surface urine has been sitting in. Separating the bag from the catheter tubing breaks the closed system and is a leading cause of catheter-associated infection. Emptying into the toilet destroys the measurement, and an estimated volume is of no use on an output record.

A technician is assisting with postmortem care shortly after a patient's death. Which action is part of the technician's role?

• a.Remove the wedding ring and put it into the drawer of the bedside stand
• b.Lay the body flat and turn it face down to slow the color change
• c.Position the body in normal alignment with the head slightly raised✓
• d.Open the curtain so that family can be seen from the hallway

The body is straightened into normal alignment before rigor mortis sets in, and the head and shoulders are raised on a pillow so that blood settling in the face does not discolor it. Personal belongings and valuables are inventoried and released according to facility policy, usually with a second person as witness and documentation of who received them, rather than being slipped into a drawer. Turning the body face down is not done and would worsen the discoloration of the face. Privacy and dignity continue after death exactly as before it, so the curtain and the door stay closed while care is given and while the family is at the bedside.

During a stand-pivot transfer from the bed to a chair, a patient's knees buckle and the patient begins to slide toward the floor. What should the technician do?

• a.Grip the patient under both arms and lift back onto the bed
• b.Hold the patient upright and call the supervisor to the room
• c.Ease the patient down to the floor, protecting the head✓
• d.Step away quickly so the technician is not pulled down too

A falling adult cannot be held up safely, and trying to hold or lift the patient is how both the patient and the technician get hurt. The technician widens the stance, brings the patient close to the body, and slides the patient down the technician's leg to the floor while supporting and protecting the head, then stays with the patient and calls for help. Lifting a buckling patient under the arms risks shoulder injury to the patient and a back injury to the technician. Standing there holding the patient while calling for help only delays the controlled descent, and stepping away leaves the patient to fall unprotected.

A technician is assigned to move a patient with a full-body mechanical lift, a model the technician has not been trained to operate. The patient is waiting to be moved into the chair. What is the best action?

• a.Ask the supervisor for training on this lift before using it with a patient✓
• b.Read the instruction label on the lift and then operate it with a second aide
• c.Do a stand-pivot transfer with a gait belt instead of the lift
• d.Tell the patient the transfer is delayed and go to another task

Mechanical lifts are only safe in the hands of staff trained on that specific model, and a patient in a sling is entirely dependent on correct sling selection, hook placement, and boom control. Asking the supervisor for training keeps the task inside the technician's competence and still gets the patient moved. Reading the label is not training and does not cover sling sizing or the facility's two-person rule. Substituting a stand-pivot transfer overrides the care plan for a patient the plan says cannot bear weight. Simply walking away leaves the patient waiting with no plan and no one informed.

A technician must move a heavy loaded linen cart down a corridor. Which technique best protects the technician's back?

• a.Pull the cart while walking backward, keeping the arms straight
• b.Lift the front wheels slightly and pivot at the waist to steer the cart
• c.Push the cart, keeping it close to the body and using the leg muscles✓
• d.Twist at the waist to start the cart moving, then walk forward

Pushing lets the technician use body weight and the large muscles of the legs and hips, and it keeps the load close and in view; pulling shifts the work onto the back and shoulders and means walking backward into whatever is behind. Bending or lifting the cart adds unnecessary load to the lumbar spine. Twisting at the waist under load is one of the most common mechanisms of back injury in health care; the technician should pivot with the feet instead. Keeping the back straight, the knees slightly bent, and the feet about shoulder-width apart completes safe body mechanics.

A patient with right-sided weakness after a stroke is being transferred from the bed to a wheelchair. Where should the technician place the chair?

• a.At the foot of the bed facing the patient, with the brakes released
• b.On the patient's right side, so the weaker leg leads into the chair
• c.On either side of the bed, because a gait belt is used for the move
• d.On the patient's left side, which is the stronger side✓

The chair goes on the stronger side so the patient stands and pivots toward the leg and arm that can bear weight and can help push off; here the left side is the strong side. Placing the chair on the weak right side forces the pivot onto the leg that may give way. A chair at the foot of the bed is out of reach for a short pivot, and leaving the brakes off lets the chair roll away as the patient sits. A gait belt gives the technician a hold on the patient but it does not make the direction of the pivot unimportant.

A rolled towel is tucked alongside a supine patient's hip and thigh as a trochanter roll. What is this device intended to prevent?

• a.Plantar flexion of the ankle, which leads to foot drop over time
• b.Flexion contracture of the knee in a patient confined to bed
• c.A pressure injury forming over the greater trochanter of the hip
• d.External rotation of the hip while the patient is lying supine✓

A trochanter roll is a firm roll placed from the top of the iliac crest to mid-thigh; it blocks the leg from rolling outward, keeping the hip in neutral alignment. Its name comes from where it sits, not from what it protects, so choosing pressure relief over the greater trochanter is a natural trap; pressure over that bony point is relieved by turning schedules and side-lying support, not by a roll wedged against it. Foot drop is prevented by a footboard or ankle support, and knee contracture by limiting how long the knee is left flexed over a pillow.

A footboard is placed against the soles of a supine patient's feet. Which complication is this intended to prevent?

• a.External rotation of the hips while the patient is lying flat
• b.Foot drop from plantar flexion contracture✓
• c.Pressure injury on both heels from resting on the mattress
• d.Swelling of the feet and ankles during prolonged bed rest

Left unsupported, the weight of the bedding pulls the feet into plantar flexion, and over weeks the calf muscles and Achilles tendon shorten into a fixed contracture called foot drop that prevents a normal heel-to-toe gait. A footboard, or high-top shoes, holds the ankles near 90 degrees. Heel pressure injuries are prevented by floating the heels off the mattress with a pillow under the calves, not by pushing the soles against a board. External hip rotation is controlled by trochanter rolls, and dependent swelling by elevation and position changes.

A patient with left-leg weakness is learning to walk with a standard pickup walker. Which sequence should the technician reinforce?

• a.Step forward with the right leg, then lift the walker ahead
• b.Move the walker ahead, step with the weaker left leg, then the right✓
• c.Move the walker and both legs forward together in one smooth motion
• d.Step with the weaker left leg, then lift the walker ahead of both feet

With a pickup walker the device is placed first, about an arm's length ahead with all four legs on the floor, and only then does the patient step in: weaker leg first into the frame, then the stronger leg. The weak leg moves while the walker and the strong leg are both stable, which is where the support is needed. Stepping with the strong leg first leaves the weak leg to carry the body alone at the end of the step. Moving the walker while stepping, or moving the walker after the weak leg, means the patient is unsupported at the least stable moment. The patient should stay inside the frame and not step past the front legs.

A patient using crutches with a non-weight-bearing left leg is going up a flight of stairs. What should move up onto the step first?

• a.Both crutches move up onto the step, and the right leg follows
• b.The left leg is lifted up onto the step with the crutches held clear
• c.The stronger right leg steps up to the next step first✓
• d.The crutches and the left leg move up onto the step at the same time

The teaching phrase is up with the good, down with the bad: going up, the stronger leg leads onto the step while the crutches and the affected leg stay on the lower step to bear the load, and the crutches then come up. Going down, the crutches and the weaker leg go down first, and the stronger leg follows. Leading with the crutches or with the affected leg on the way up forces the weak side to lift the body's weight. The technician stands behind and slightly to the affected side going up, and one step below the patient going down.

A patient with severe shortness of breath is helped into the orthopneic position. How is this patient positioned?

• a.Sitting upright and leaning forward onto an overbed table, arms resting on it✓
• b.Lying flat on the back with a pillow under the head and under both knees
• c.Side-lying with the lower arm behind the back and the upper knee flexed
• d.Flat on the back with the whole bed tilted so the head is lower

In the orthopneic position the patient sits and leans forward over a padded overbed table, which lets the chest expand fully and lets the arms and shoulders anchor the accessory muscles of breathing, so it is often chosen by patients with COPD or heart failure who cannot breathe lying down. Lying flat with a pillow under the knees is dorsal recumbent positioning and worsens dyspnea. The side-lying description with the lower arm behind the back is Sims' position. Tilting the whole bed head-down is Trendelenburg, which pushes the abdominal organs against the diaphragm and makes breathing harder.

While repositioning a patient, a technician finds a 3 cm area of intact, deep purple skin on the left heel that does not blanch. What should the technician do?

• a.Massage the discolored area with lotion to restore circulation to the heel
• b.Cover the heel with a dressing and document it at end of shift
• c.Chart the heel as a stage 2 pressure injury and continue the turn schedule
• d.Keep pressure off the heel and report it to the nurse or supervisor now✓

Intact skin that is deep purple or maroon and non-blanchable suggests a deep tissue pressure injury, meaning damage has already occurred in the tissue under the surface, and such an area can deteriorate quickly even with treatment. Relieving pressure by floating the heel and reporting the finding promptly are both required, and staging or charting a diagnosis is the nurse's assessment, not the technician's. Massaging discolored skin over a bony point is an old practice now avoided because it can worsen the underlying tissue damage. Waiting until the end of shift to document delays the nursing assessment on a lesion that can open within hours. A stage 2 injury involves partial-thickness skin loss, which this intact area does not show.

The head of a patient's bed is raised to 45 degrees and the patient slowly slides toward the foot of the bed. The skin over the sacrum stays against the sheet while the deeper tissue and bone move downward. Which mechanism does this describe?

• a.Friction, the rubbing of the skin surface against the bed linens
• b.Moisture damage from perspiration trapped under the patient's body
• c.Direct pressure from body weight on skin over a bony prominence
• d.Shear, in which deeper tissue slides while the surface skin holds still✓

Shear happens when two layers move in opposite directions: the sacral skin is held by the sheet while the skeleton slides down, so the blood vessels between the layers stretch and kink and the tissue under intact skin loses its supply. Friction is the surface injury from skin dragging across linen, which scrapes the epidermis but does not distort the deeper layers. Direct pressure describes the load itself rather than this sliding motion, and moisture softens skin and makes it more vulnerable but is not what the scenario shows. Keeping the head of the bed at 30 degrees or lower when the condition allows, and lifting rather than dragging the patient, are the main defenses.

A nurse is completing a Braden Scale score for a newly admitted patient. Which action is the technician's appropriate contribution?

• a.Assign the sensory perception and moisture subscores from the shift's care
• b.Decide which pressure-redistribution mattress the patient needs
• c.Repeat the Braden score at end of shift and chart the total
• d.Report observations of moisture, meal intake, and mobility to the nurse✓

The Braden Scale is a nursing assessment with six subscales, and scoring it, repeating it, and acting on the total are nursing responsibilities. The technician is at the bedside for the care that generates the raw information, so accurate reporting of how much of the meal was eaten, how often the patient was incontinent or diaphoretic, and how much the patient moved is a genuine and valuable contribution. Assigning subscores or repeating the total is scoring the tool. Selecting a support surface is a clinical decision made by the nurse or the provider based on the score and the patient's condition.

A patient is placed in the prone position for a short period. Which sites should the technician check most closely for pressure?

• a.The cheek and ear, the chest, the knees, and the toes✓
• b.The sacrum, both heels, and the back of the head
• c.The greater trochanter, the down-side ear, and the outer ankle
• d.The ischial tuberosities and the backs of the patient's thighs

Pressure points follow whatever bone is nearest the mattress. Face down, the load falls on the cheek and ear, the chest, the iliac crests, the knees, and the dorsal surface of the toes, so a small pillow under the lower legs to lift the toes clear and a flat pillow under the abdomen are standard. The sacrum, heels, and occiput are the supine points. The trochanter, the down-side ear, and the lateral ankle are the side-lying points. The ischial tuberosities carry the load when a patient is sitting up in a chair, which is why chair time is limited and weight shifts are encouraged.

A patient recovering from a shoulder injury starts to raise the arm but cannot finish the movement, so the technician supports the elbow through the rest of the arc. This exercise is best described as:

• a.Active-assisted range of motion, since the patient starts the motion and the technician completes it✓
• b.Passive range of motion, because the technician's hands are on the joint during the movement
• c.Resistive exercise, because the support the technician gives opposes the patient's movement
• d.Active range of motion, since the patient begins the movement without any help

Active-assisted range of motion is the middle category: the patient supplies as much of the movement as possible and the caregiver or a device supplies the rest, which is exactly what happens when the technician carries the arm through the last part of the arc. Passive range of motion means the patient contributes no muscle effort at all, and active range of motion means the patient completes the movement unaided. Resistive exercise means the patient works against an opposing force to build strength, while here the technician is helping rather than opposing. Movements are carried out slowly, to the point of resistance and no further.

During range-of-motion exercises the technician turns a patient's forearm so that the palm faces upward. Which movement is this?

• a.Pronation, the rotation that turns the palm face down
• b.Supination, rotation of the forearm to a palm-up position✓
• c.External rotation, turning the whole arm out at the shoulder
• d.Radial deviation, bending the wrist toward the thumb

Supination is the forearm rotation that carries the palm to face up, the position in which a bowl of soup could be held in the hand; pronation is the opposite rotation, palm down, and the two words are easy to reverse under time pressure. External rotation occurs at the shoulder and turns the whole arm outward, so a palm can end up facing forward without the forearm rotating at all, which makes it a close competitor here. Radial deviation is a wrist movement toward the thumb side. During passive range of motion the technician supports the joint above and below, stops at resistance or at the patient's report of pain, and works within the plan set by the nurse or therapist.

Under a typical facility policy, which patient is the best candidate for a transfer performed with a slide board?

• a.A patient who cannot bear weight but has strong arms✓
• b.A patient who can stand briefly and take small pivot steps to the chair
• c.A patient who is unresponsive and cannot assist with the transfer at all
• d.A patient who walks with a walker but tires after a short distance

A slide board bridges the gap between two surfaces so the patient can scoot across without standing; it depends on the patient having enough upper body strength and trunk control to push and shift weight, which is the classic picture of a patient with a spinal cord injury or bilateral lower extremity weakness. A patient who can stand and pivot does not need a board and should use that remaining strength. An unresponsive patient who cannot help at all needs a full-body mechanical lift and at least two staff. A patient who ambulates with a walker transfers by standing, with the walker or a gait belt for support.

The bed has been lowered and a patient in non-skid footwear is sitting on the edge of the bed. The technician has just rolled the wheelchair up to the patient's stronger side. What should the technician do next?

• a.Apply the gait belt and have the patient stand on the count of three
• b.Lock the wheel brakes and move the footrests aside✓
• c.Ask the patient to rest both hands on the technician's shoulders
• d.Raise the bed slightly so the patient can push up off the mattress

Securing the chair comes before the patient is anywhere near it: an unlocked chair rolls backward at the moment the patient's weight arrives, and footrests left down are the classic tripping and shin-injury hazard during a pivot. The gait belt is applied next, and it is the right action, only not the first one here. A patient should hold the technician's forearms or the chair rather than the shoulders, because pulling on the shoulders or neck destabilizes both people. The bed is left low enough that the patient's feet are flat on the floor, so raising it again removes that stable base.

As a technician settles a patient into a chair, the patient's peripheral IV catheter is pulled out by the tubing and the site begins to bleed steadily. What should the technician do first?

• a.Ask the supervisor whether the catheter may go back into the same vein
• b.Wipe the blood away and cover the site with a large adhesive bandage
• c.Raise the patient's arm overhead and wait for the bleeding to stop
• d.Hold direct pressure on the site with clean gauze✓

Active bleeding is controlled first, with gloves on and firm direct pressure over the puncture site until it stops, and only then is the nurse notified and the event documented. Restarting an IV is outside the technician's role and is not a first action while the site is bleeding, so the escalation here delays the one thing that has to happen immediately. Covering a bleeding site with a bandage without pressure lets blood collect under the dressing and hides how much is being lost. Raising the arm alone does not close a punctured vein. Elevation may be added after pressure is applied.

A technician is ambulating a patient who has left-sided weakness, using a gait belt. Where should the technician walk?

• a.In front of the patient, holding both of the patient's hands
• b.Slightly behind and on the patient's weaker left side✓
• c.On the patient's right side, holding the belt with one hand
• d.Beside the patient at arm's length, ready to catch a fall

The technician walks slightly behind and to the weaker side, holding the gait belt underhand at the back, because that is the side the patient will drift or fall toward and that position lets the technician control the descent to the floor. Walking on the strong side leaves the weak side unguarded. Walking backward in front of the patient blocks the path, prevents the technician from seeing where either of them is going, and gives no way to lower a falling patient. Staying an arm's length away is too far to control a fall that starts without warning.

During passive range-of-motion exercises the technician meets firm resistance in a patient's shoulder, and the patient grimaces and says it hurts. What should the technician do?

• a.Move the joint a little further with each repetition to stretch the tissue
• b.Hold the stretch at the painful point for a slow count of ten, then let go
• c.Stop at that point and report the pain to the supervisor✓
• d.Finish the remaining shoulder movements faster to shorten the discomfort

Range-of-motion exercises are carried out slowly to the point of resistance or the first sign of pain, and no further; forcing past that point can tear soft tissue, dislocate a joint, or fracture a bone in a patient with osteoporosis or spasticity. New pain or new resistance is a change in condition, so exercise stops and the finding goes to the nurse or supervisor before it is repeated. Pushing further each repetition and holding a painful stretch both continue the very force that caused the pain. Moving faster increases the risk rather than reducing it, because momentum takes the joint past its safe limit.

A resident recovering from a stroke is relearning to put on a shirt and takes several minutes to work the weaker arm into the sleeve. Which approach best supports restorative care?

• a.Allow the extra time and cue the resident through each step of the task✓
• b.Dress the resident quickly now and practice on another day
• c.Slide the shirt onto the stronger arm first so the task takes less effort
• d.Complete the sleeve for the resident after the first attempt fails

Restorative care is built on the resident doing the task at the resident's own pace, with verbal cues, adaptive equipment, and setup rather than hands-on completion, because every repetition maintains the function that was regained. Taking over the task, whether at the start or after one failed attempt, is faster for the shift and costs the resident the skill. Dressing the weaker arm first is the correct technique and dressing the stronger arm first makes the task harder, since the weak arm then has to be pushed through a sleeve that is already anchored. Progress is reported so the plan of care can be updated.

Two technicians need to move a patient who has slid toward the foot of the bed back up toward the head of the bed. Which method best protects the patient's skin and the technicians' backs?

• a.Use a friction-reducing lift sheet with one technician on each side✓
• b.Grasp the patient under both arms and pull toward the headboard
• c.Raise the head of the bed and have the patient pull up on the side rails
• d.One technician lifts the shoulders and the other the hips

A lift sheet or friction-reducing slide sheet lets two people move the patient as one unit without dragging skin across the linen, and it keeps the load close to each technician's center of gravity. The bed is flattened first and raised to waist height, the technicians face the head of the bed with feet apart and knees bent, and they move on a count. Pulling under the arms puts traction on the shoulder joints and can injure the brachial plexus. Raising the head of the bed works against the move and increases shear. Lifting a patient by the shoulders and hips by hand strains both backs and grinds the skin along the sheet.

A technician cleans and disinfects a shared glucose meter after each patient use. Which link in the chain of infection does this practice break?

• a.The mode of transmission, because a shared device carries organisms✓
• b.The reservoir, because the meter is where the organisms live and multiply
• c.The portal of entry, because organisms enter through the fingertip puncture
• d.The susceptible host, because the next patient stays well

A shared device that moves organisms from one patient to the next is a fomite, and a fomite is a vehicle for indirect contact transmission. Disinfecting it between patients removes the organisms from that route, so the link being broken is the mode of transmission. A reservoir is where an organism naturally lives and multiplies, such as an infected person, contaminated water, or a colonized wound, and bacteria do not multiply on a dry meter surface. The portal of entry is the puncture site itself, which is controlled by skin antisepsis, and the susceptible host link is addressed by measures such as immunization and good nutrition rather than by equipment cleaning.

Several patients on one unit develop gastrointestinal illness after eating from a food cart that was contaminated during preparation. Which mode of transmission does this describe?

• a.Indirect contact, because a contaminated surface touched the patients
• b.Droplet spread from staff standing close to the patients
• c.Vector transmission, because an insect carried organisms onto the food
• d.Common vehicle transmission through a contaminated food source✓

Food, water, medications, blood products, and intravenous fluids are common vehicles: one contaminated source reaches many people at once, which is why several patients became ill together. Indirect contact also involves an object, but it describes a single contaminated item passing organisms from one person to another, not a batch source distributed to a group. Droplet spread requires large respiratory droplets traveling a short distance from a coughing or sneezing person, and nothing in this outbreak points to respiratory contact. Vector transmission requires a living carrier such as a mosquito, tick, or flea.

Which patient on a medical unit is the most susceptible host for a healthcare-associated infection?

• a.A 78-year-old receiving chemotherapy with a low white blood cell count✓
• b.A 44-year-old admitted overnight for observation after a fall
• c.A 70-year-old with a short-term urinary catheter and no other health problems
• d.A 25-year-old with a healing laceration who walks in the hallway each day

Susceptibility depends on how well the host can defend itself, and chemotherapy that drops the white blood cell count removes the cells that fight organisms off; advanced age adds a weaker immune response and thinner skin. An indwelling urinary catheter is a real risk because it creates a portal of entry, but a patient whose immune defenses are intact can still clear organisms that get past that portal, so the neutropenic patient is more susceptible. A short observation stay after a fall involves little device exposure and no immune impairment. A healing laceration in a young, mobile patient shows intact defenses at work.

A patient with an indwelling urinary catheter needs the drainage bag emptied at the end of the shift. Which action protects the closed drainage system?

• a.Disconnect the tubing at the catheter and drain it into the toilet bowl
• b.Empty through the drain port into a container used for this patient✓
• c.Raise the bag above the bladder briefly so the tubing drains fully
• d.Open the drain port and let it touch the rim of the shared hopper

An indwelling catheter and its tubing form a closed system, and every break in that system gives bacteria a direct route to the bladder, so the bag is emptied through its own drain port and the port is not allowed to touch anything. Each patient has a dedicated collection container, because a container carried between rooms moves organisms with it. Disconnecting the tubing at the catheter breaks the closed system outright, and lifting the bag above the bladder sends urine that has been sitting in the bag back toward the patient. Hand hygiene and gloves are performed before and after, and the drain port is disinfected before it is reclosed.

A technician puts on clean gloves to change a patient's brief and removes the gloves when the task is finished. When is hand hygiene indicated for this task?

• a.Before putting the gloves on and again immediately after taking them off✓
• b.Only after the gloves are removed, since the hands were clean before
• c.Only if a glove tears or the hands are visibly soiled
• d.Once at the start of the shift and once when leaving the unit

Gloves are an addition to hand hygiene, not a replacement for it, so hands are cleaned before donning and again after doffing. Gloves have microscopic defects and hands are readily contaminated during removal, which is why hand hygiene after glove removal is required even when the gloves stayed intact. Cleaning only afterward ignores the organisms already on the hands that can be transferred to the inside of the gloves and to any supplies handled on the way in. Waiting for a visible tear or visible soil misses the ordinary contamination that gloves are meant to contain, and hand hygiene done twice a shift ignores every moment of care in between.

While assisting a coughing patient who is on droplet precautions, a technician's surgical mask becomes damp from the patient's secretions. What should the technician do?

• a.Continue the task and change the mask when care is finished for the shift
• b.Notify the supervisor and wait for direction before continuing care
• c.Cover the damp mask with a second surgical mask and finish the task
• d.Step out of the room, remove the mask, perform hand hygiene, and put on a dry one✓

A mask filters by trapping droplets in dry fibers; once it is damp it no longer forms a barrier and the moisture itself wicks organisms through to the face, so it is removed and replaced before care continues. Hand hygiene belongs between removing the wet mask and handling the clean one, because the front of the used mask is contaminated. Finishing the task first leaves the technician working without effective protection during exactly the exposure that wet the mask. Layering a second mask over a wet one does not restore filtration and worsens the seal, and waiting for direction delays a correction the technician is trained and expected to make immediately.

A technician who has been fit-tested for an N95 respirator is about to enter an airborne infection isolation room. What must be done each time the respirator is put on?

• a.Repeat the fit test with the respiratory protection program manager
• b.Perform a user seal check by covering the respirator and breathing in and out✓
• c.Pinch the metal nosepiece with one hand after the straps are in place
• d.Tie a surgical mask over the respirator to keep its outside clean

A user seal check is done every single time the respirator is donned: the wearer covers the facepiece and inhales and exhales to confirm that it collapses slightly inward and that no air leaks around the edges. Fit testing is a separate, formal procedure done before first use and repeated at least annually or when the face changes, so it does not substitute for the check at the door. Molding the nosepiece with one hand tends to crease it and create a leak, so it is shaped with the fingers of both hands. Placing a surgical mask over the respirator interferes with the seal that the respirator depends on.

A technician is assigned to a patient receiving mechanical ventilation. Which routine measure helps prevent ventilator-associated pneumonia?

• a.Keep the bed flat during care so that oral secretions drain from the airway
• b.Suction the endotracheal tube hourly whether or not secretions are heard
• c.Keep the head of the bed raised 30 to 45 degrees unless contraindicated✓
• d.Let condensate in the circuit tubing drain back toward the patient

Elevating the head of the bed 30 to 45 degrees uses gravity to keep secretions from the mouth and stomach out of the lower airway, which is the route most ventilator-associated pneumonia takes; the technician reports when a position change or a procedure requires the head to be lowered. A flat bed does the opposite and lets pooled secretions run toward the tube. Suctioning on a clock rather than on assessment traumatizes the airway and introduces organisms with each pass. Condensate in the circuit is contaminated fluid, so it is drained away from the patient and discarded rather than allowed to run back down the tubing.

A patient is admitted with disseminated varicella (chickenpox). Which transmission-based precautions are required in addition to standard precautions?

• a.Contact precautions with a gown and gloves for anyone entering the room
• b.Droplet precautions with a surgical mask worn within 3 to 6 feet
• c.Airborne precautions in a negative-pressure room plus contact precautions✓
• d.Protective isolation with the door kept closed and visitors screened

Varicella-zoster spreads two ways at once: the virus travels in small airborne particles that stay suspended and move on air currents, and the fluid in the vesicles is infectious on contact. Both precautions are therefore combined, with an airborne infection isolation room and a fitted respirator plus a gown and gloves. Using contact precautions alone leaves the airborne route open, which is how this virus reaches people who never touched the patient. Droplet precautions cover only large droplets that fall within a few feet and would not contain suspended particles, and protective isolation is designed to keep organisms away from an immunocompromised patient rather than to contain them.

A patient on airborne precautions for pulmonary tuberculosis must be taken to the radiology department. What protects others along the route?

• a.The patient wears a surgical mask and the trip is kept as brief as possible✓
• b.The patient wears an N95 respirator that was fit-tested for the unit's staff
• c.The technician wears a gown and gloves for the length of the transport
• d.The hallway is cleared of visitors before the stretcher leaves the room

When the source of the organisms leaves the isolation room, the control moves onto the patient: a surgical mask worn by the patient contains the particles at their origin, and limiting time outside the room limits the exposure. A respirator is designed to protect the wearer from inhaled particles and is fit-tested to one individual face, so putting someone else's N95 on the patient offers no proven fit and adds breathing resistance for a patient who may be short of breath. A gown and gloves address contact spread and do nothing about particles carried in the air. Clearing the corridor cannot control air the patient exhales along the whole route and in the department.

A patient with severe neutropenia after a stem cell transplant is placed in protective (reverse) isolation. Which action fits the purpose of this precaution?

• a.Place all used linen in a red biohazard bag before it leaves the room
• b.Wear a gown and gloves to keep the patient's organisms off the uniform
• c.Keep the room door open so staff can watch the patient more closely
• d.Keep fresh flowers, potted plants, and standing water out of the patient's room✓

Protective isolation runs in the opposite direction from the other precautions: it shields a patient with almost no immune defense from organisms in the environment. Standing water and the soil of flowers and plants harbor molds and gram-negative bacteria that a neutropenic patient cannot fight off, so they are kept out, and staff or visitors with any respiratory infection stay away. Bagging linen as regulated waste addresses spread from the patient, which is not the concern here. A gown and gloves are worn to protect this patient rather than the uniform, and the door is kept closed because the room is kept under positive pressure so filtered air flows outward.

A nurse asks a technician to open a sterile tray and set up a sterile field for a central line dressing change. The technician has never been trained or checked off on setting up a sterile field. What should the technician do?

• a.Ask the supervisor whether this task is within the technician's role✓
• b.Open the tray, since the nurse will handle the sterile portion anyway
• c.Open the tray while wearing sterile gloves so the field stays untouched
• d.Refuse the request and document the refusal in the patient's chart

Setting up a sterile field is a trained skill whose steps are invisible once the field is contaminated, and whether a technician may perform it depends on state rules, facility policy, and documented training. Clarifying the assignment with the supervisor before acting protects the patient from a silently contaminated field and protects the technician from working outside a defined role. Opening the tray on the assumption that someone else owns the sterile part still puts the untrained person in charge of the moment the field is created. Sterile gloves do not make an untrained setup safe, and a flat refusal without clarification leaves the nurse without help and the scope question unanswered.

A technician sustains a needlestick from a used lancet and has already washed the site thoroughly with soap and running water. What should be done next?

• a.Squeeze the puncture site to force out as much blood as possible
• b.Apply an antiseptic, finish the shift, and report the stick in the morning
• c.Ask the patient whether they carry a bloodborne infection before reporting
• d.Report the exposure to the supervisor now so evaluation can begin✓

After washing, the next step is immediate reporting through the facility's exposure control plan, because post-exposure evaluation is time-sensitive: source-patient testing, baseline labs, and any prophylaxis for HIV or hepatitis B work best when they start within hours. Waiting until the end of the shift throws away that window and weakens the record of a work-related injury. Squeezing or milking the wound damages tissue and has not been shown to reduce infection risk. Source testing is arranged through the exposure protocol with consent handled by the facility, so it is not something the injured technician negotiates at the bedside.

A technician finds a small spill of blood on the floor of a patient's room and facility policy assigns small spills to clinical staff. What should the technician do?

• a.Wipe the spill with dry paper towels and then mop the area with water
• b.Notify the supervisor and leave the spill uncovered until help arrives
• c.Put on gloves, absorb the spill, then disinfect the area per policy✓
• d.Pour disinfectant over the spill and let it air dry without wiping

A blood spill is cleaned in that order: gloves and any other protection needed against splashing, absorbent material to lift the visible blood, then an EPA-registered hospital disinfectant effective against bloodborne pathogens, or freshly diluted bleach, left on the surface for the contact time on the label. Mopping with water after a dry wipe spreads organisms rather than killing them and leaves no contact time at all. Disinfectant poured over pooled blood is diluted by the blood and cannot reach the surface underneath. Leaving a wet blood spill uncovered while waiting creates a slip hazard and an exposure hazard in a task the technician is assigned and equipped to complete.

Which task requires surgical asepsis rather than medical asepsis?

• a.Wiping a shared blood pressure cuff with a disinfectant wipe
• b.Washing the hands before helping a patient with a meal tray
• c.Opening a sterile urinary catheter insertion tray✓
• d.Bagging soiled linen in a leak-resistant bag in the room

Surgical asepsis means every organism is absent from the item and the field, and it is required whenever something enters a normally sterile body area; a urinary catheter enters the bladder through the urethra, so its tray is opened by sterile technique. Medical asepsis, or clean technique, aims to reduce the number of organisms and keep them from spreading, which is the standard for handwashing before meal assistance, for disinfecting shared equipment between patients, and for bagging soiled linen. Disinfecting a cuff kills most organisms on an intact surface but leaves spores, so it is clean rather than sterile. Confusing the two levels usually shows up as treating a sterile procedure as merely clean, which is how organisms are introduced into the urinary tract.

A technician is helping a nurse who has set up a sterile field at the bedside. Which action by the technician would contaminate the field?

• a.Reaching across the top of the field to place an item on the far side✓
• b.Opening the flap of a sterile wrapper farthest from the body first
• c.Holding a wrapped sterile package above waist level while it is opened
• d.Standing so the field stays in view and not turning away from it

Anything passing over a sterile field can shed skin scales, lint, or droplets onto it, so supplies are added from the side or dropped from the edge rather than by reaching across the top. The outer flap of a wrapper is opened away from the body first so the hand never crosses the contents that are already exposed. Sterile items are kept above waist level and in continuous view because anything below the waist or out of sight is considered contaminated whether or not it was touched. The one-inch border of a sterile drape is also treated as contaminated, which is why items are placed toward the center.

A technician is removing soiled bed linen from a patient's bed. Which technique is correct?

• a.Shake the linen out over the bed to loosen debris before bagging it
• b.Hold the linen away from the uniform and bag it in the room✓
• c.Carry the linen against the chest to the hamper in the hallway
• d.Set the linen on the floor beside the bed until a hamper is brought in

Soiled linen is rolled inward with the dirty surface toward the center, held away from the body, and placed in the hamper or bag inside the patient's room so contaminated fabric is not carried through the unit. Shaking or fanning linen releases skin scales and organisms into the air and onto every surface nearby, which is why linen is never agitated. Pressing it against the chest transfers organisms to the uniform, which then travels to the next patient. The floor is considered contaminated, so linen placed there can no longer be handled as merely soiled and adds a tripping hazard in an occupied room.

Which item must be discarded in a red biohazard bag rather than in regular trash?

• a.An empty IV bag with no visible blood
• b.A dressing saturated with blood✓
• c.A gown worn to feed a patient in isolation
• d.A paper towel used after handwashing

Regulated medical waste is material soaked or saturated with blood or other potentially infectious material, items that would release that material if compressed, and items caked with dried blood; a saturated dressing meets that definition and goes in the labeled red bag. An isolation gown that is merely worn, a paper towel from handwashing, and tubing or bags with no visible blood are handled as regular waste under most facility policies, even though they came from a precaution room. Treating every item from an isolation room as regulated waste raises disposal cost sharply without adding protection. When there is doubt about a specific item, facility policy and the labeling on the container settle it.

A technician is wheeling a portable vital signs monitor toward a room and notices that the insulation on its power cord is cracked open and bare wire shows through. What should the technician do?

• a.Wrap the damaged section with tape and finish the shift's vital sign rounds
• b.Plug the monitor into a different wall outlet and watch it for sparking
• c.Take the monitor out of service and tell the supervisor✓
• d.Return the monitor to the equipment room for the next shift to use

Exposed conductors are a shock and fire hazard, so the device is pulled from use immediately and the problem goes to the person who can have it repaired or replaced. Tape over damaged insulation is not a repair; it hides live wire under a layer that peels in a warm room. Moving the plug to another outlet changes nothing, because the defect is in the cord itself. Setting the monitor back on the equipment shelf without tagging it simply hands the hazard to whoever grabs it next.

A visitor becomes loud and threatening, steps between a technician and the doorway of a patient's room, and demands that someone come at once. What should the technician do first?

• a.Take hold of the visitor's arm and guide him out into the hallway
• b.Keep the doorway clear, step out, and notify the supervisor and security✓
• c.Continue providing care quietly so the visitor has nothing more to argue with
• d.Warn the visitor that the police will be called if he does not step aside

In a threatening encounter the first move is to protect an escape route and bring in people trained and authorized to handle it, rather than to stay in a room with someone escalating. Putting hands on an agitated visitor invites a physical fight and is outside the technician's role. Carrying on with care as though nothing is happening leaves the technician cornered with a patient who also cannot leave. Threatening the visitor with police raises the emotional temperature at the exact moment it needs to come down.

Four patients on a medical unit walk with standby assistance. Which one carries the highest fall risk today?

• a.A patient who has used the same rolling walker at home for the past three years
• b.A patient started on a diuretic yesterday who feels dizzy on standing up✓
• c.A patient with an indwelling catheter and an IV pole who walks to the window daily
• d.A patient in his own eyeglasses who walks to the bathroom each morning

A drug started yesterday plus dizziness on rising describes orthostatic hypotension, an acute and modifiable cause of falls that shows up on the first few steps out of bed. Tethers such as a drainage bag and an IV pole do raise risk and are worth a second look, but that patient is at his baseline and ambulates daily, while the newly medicated patient's balance changed overnight. A walker used for years at home is familiar equipment rather than a new hazard. Wearing his own corrective lenses lowers rather than raises this patient's risk.

A unit adopts purposeful hourly rounding as a fall-reduction program. Which set of actions during those rounds does the most to lower fall rates?

• a.Dimming the room lights and drawing the door most of the way shut for quiet rest
• b.Recording a full set of vital signs on every patient at the top of each hour
• c.Offering the toilet, easing pain, repositioning, and placing items in reach✓
• d.Reminding each patient at the door to press the call light before rising

Purposeful rounding works by removing the reasons a patient gets up alone, summarized as the four Ps: potty, pain, position, and possessions. Reminders to use the call light help, but a patient with a full bladder who has waited ten minutes will still stand up, which is why anticipating the need beats instructing the patient about it. Hourly vital signs generate data without meeting any of the needs that put a patient on the floor. Dimming lights and closing the door reduces stimulation but also reduces the visibility and observation that protect a patient at risk.

A technician removes a dressing and finds a venipuncture site on the forearm bleeding steadily and soaking the gauze. The patient is alert and talking. What should the technician do first?

• a.Leave the room to report the bleeding to the supervisor before touching the site
• b.Apply a tourniquet above the elbow and loosen it every few minutes
• c.Wipe the site with alcohol and tape a light dressing so the clot is not disturbed
• d.Hold firm, steady direct pressure over the site with clean gauze✓

Direct pressure over the bleeding point is the first and most effective control of external bleeding, and the technician applies it immediately while calling out for help rather than walking away from an actively bleeding patient. Reporting matters, but it happens with the hand still on the site or through someone else, because blood loss continues the entire time the room is empty. A tourniquet is reserved for life-threatening limb hemorrhage that pressure cannot control and is not used on a venipuncture site. Alcohol and a loose dressing do nothing to stop flow, and alcohol interferes with clotting at the puncture.

A seated patient begins a generalized convulsion with stiffening and jerking of all four limbs. What should the technician do?

• a.Ease him to the floor, cushion his head, turn him onto his side, and note the time✓
• b.Hold his arms and legs still so he does not strike the bed rails or the wall
• c.Slide a padded tongue blade between his teeth to keep the airway open
• d.Offer sips of water as soon as the jerking movements have stopped completely

Seizure care is protective, not corrective: lower the patient so he cannot fall, pad the head, clear hard objects away, position him on his side so secretions drain, and time the event, because duration drives what the team does next. Holding the limbs down does not shorten the seizure and can dislocate a shoulder or break a bone. Nothing goes into the mouth of a seizing patient; the tongue cannot be swallowed, and a blade between clenched teeth chips them or ends up in the airway. Fluids are withheld until the patient is fully alert and swallowing, since a postictal patient aspirates easily.

A technician walks into a room and finds a patient sitting on the floor next to her bed. She is awake and says she slipped. No one saw it happen. What should the technician do first?

• a.Help her back into bed and then take a full set of vital signs
• b.Ask her to stand and take a few steps to show whether anything hurts
• c.Get a second technician and lift her into the chair before checking her
• d.Stay with her, check her for injury, and call for help without moving her✓

An unwitnessed fall is treated as a fall with an unknown mechanism, so the patient is assessed for injury where she lies and is not moved until someone qualified has cleared her; moving a patient with a hip fracture or a head injury can turn a bad outcome into a worse one. Getting a second person is the right idea for the lift itself, but the lift comes after the assessment, not before it. Helping her up first and taking vital signs afterward reverses that order. Asking an injured patient to bear weight as a test risks a second fall and tells the team nothing reliable.

A visibly pregnant woman in the lobby suddenly clutches her throat, cannot speak, and cannot cough. She is standing and awake. Which technique should the technician use?

• a.Abdominal thrusts delivered just above the navel with both fists
• b.Chest thrusts delivered at the center of the breastbone from behind✓
• c.Repeated back blows between the shoulder blades until the object comes out
• d.Lower her to the floor at once and begin chest compressions

For a choking adult who is pregnant, or whose abdomen the rescuer cannot get her arms around, the thrusts are moved up to the center of the sternum, which generates the same pressure spike without compressing the uterus. Abdominal thrusts are correct for most choking adults, and that is exactly the trap here: the technique changes with the late-pregnancy abdomen. Back blows may be used along with thrusts, but the answer that stops at back blows leaves out the thrusts that actually relieve the obstruction. Chest compressions on the floor belong to the moment the victim becomes unresponsive, not while she is standing and awake.

A 6-month-old infant in a clinic waiting area is choking on a piece of food, is awake, and can neither cry nor cough. What should the technician do?

• a.Sweep a finger through the mouth to locate and hook the object out
• b.Deliver abdominal thrusts with two fingers just above the navel
• c.Give five back blows, then five chest thrusts, and repeat the cycle✓
• d.Hold the infant up by the ankles and pat firmly between the shoulders

For a responsive choking infant the sequence is five back blows with the infant face down and head lower than the chest, then five chest thrusts with two fingers on the sternum, repeated until the object comes out or the infant becomes unresponsive. Abdominal thrusts are not used under one year of age because the liver sits low and unprotected and tears easily. A blind finger sweep is contraindicated at any age; it usually pushes the object deeper into the airway. Suspending an infant by the ankles offers no useful force and risks dropping the child.

A patient collapses on the wet tile of a shower room, is unresponsive, and is not breathing normally. His chest is soaked. An AED is brought to the scene. What should be done about the water?

• a.Lay a folded towel over the skin and place the pads on top of the towel
• b.Hold the AED and give compressions only until the skin has air dried
• c.Move him off the wet floor, wipe the chest dry, and then attach the pads✓
• d.Wait for the nurse to confirm an AED may be used on a wet patient

Water on the chest lets current track across the skin between the pads instead of through the heart, and standing water under the patient is a hazard to rescuers, so the fix is to drag him clear of the puddle and towel the chest dry, which takes seconds. Defibrillation is not withheld for wetness; every minute without a shock in a shockable rhythm costs survival, so drying is done fast rather than thoroughly. Pads must adhere to bare skin, so placing them over a towel guarantees they will not work. Nothing about this situation calls for pausing resuscitation to seek permission.

A technician enters a room where oxygen is running at 3 L/min by nasal cannula and finds a visitor holding a lighter to a cigarette by the window. What should the technician do?

• a.Ask the visitor to put it out right away, take it out of the room, and report it✓
• b.Turn the oxygen off at the flowmeter until the visitor finishes smoking
• c.Step out and ask the supervisor how the facility handles smoking in rooms
• d.Open the window wide and draw the privacy curtain while care continues

Oxygen does not burn but it makes everything around it burn faster and hotter, so an open flame in an oxygen-enriched room is an immediate fire emergency that the technician stops on the spot before doing anything else. Leaving to ask how the policy reads leaves a lit flame beside flowing oxygen. Shutting off the flowmeter takes therapy away from a patient who needs it and does not remove the oxygen already saturating the bedding and curtains. Ventilating the room does not clear that saturation quickly enough to matter while the cigarette is still burning.

A confused patient is seated in a reclining geriatric chair with a locked tray table across the front that she cannot remove or get past on her own. This arrangement is best described as:

• a.a supportive positioning device rather than a restraint
• b.a physical restraint, whatever the intent✓
• c.a fall-prevention aid that sits outside restraint rules
• d.a restraint only if the patient objects to the tray table

Any manual method or device attached to or next to the body that the patient cannot remove easily, and that restricts free movement or normal access to the body, meets the definition of a physical restraint. The definition turns on the effect on the patient, not on what the staff meant by it, so calling the tray a positioning aid or a fall-prevention device does not exempt it from restraint requirements such as an order, monitoring, and documentation. A patient's silence is not consent either; a compliant or confused patient who cannot object is still restrained. Labeling matters because the protections attach to the label.

A limb restraint has been ordered, and a technician trained on the device is applying it. How should the strap be secured?

• a.To the bed frame, using a knot that releases with a single pull✓
• b.To the side rail, so the strap travels with the rail when it is lowered
• c.With a double square knot the patient cannot work loose over time
• d.Under the mattress beneath the patient, out of reach

Restraint straps are tied to the bed frame with a quick-release knot so that one pull frees the limb in a fire, a code, or an episode of vomiting, when seconds spent picking at a knot are seconds the patient does not have. Tying to a side rail is the classic error: when the rail is lowered the strap drags the limb with it and can injure the arm or compress the chest. A double square knot is exactly what a quick-release knot is meant to replace, and scissors are not a substitute for a knot that opens by hand. Anchoring under the mattress gives no control over slack and puts the release point where no one can reach it.

A patient's face suddenly droops on one side and his speech becomes slurred. The technician calls for the nurse immediately. Which additional information is most important to report?

• a.The time the patient was last known to be well✓
• b.The time of the patient's last meal and how much he ate
• c.Whether anyone in the patient's family has had a stroke
• d.The blood pressure that was recorded on the previous shift

Stroke treatment is time-limited: the therapies that reopen a blocked vessel are only options within a narrow window measured from the moment the patient was last seen normal, so that timestamp drives every decision the team makes. Family history may explain why a stroke happened but changes nothing about what is done in the next hour. A previous shift's blood pressure is stale, and a current reading will be taken as part of the response anyway. When the patient last ate matters for some procedures but is far down the list against a clock that started the moment symptoms began.

A patient with diabetes is shaky and sweaty and says he feels low. He is alert and swallowing normally, and facility policy permits a technician to give oral carbohydrate for hypoglycemia. What should the technician give?

• a.Nothing by mouth, with the bed raised, until the nurse gets there
• b.A peanut butter sandwich and a glass of milk to hold the level up
• c.About 4 ounces (120 mL) of juice, then a recheck in 15 minutes✓
• d.A diet soft drink and crackers so the sugar does not spike

The standard response to hypoglycemia in an alert patient who can swallow is roughly 15 grams of fast-acting carbohydrate followed by a repeat glucose check about 15 minutes later, and 4 ounces of juice is about 15 grams. Fat and protein slow absorption, so peanut butter and milk raise the glucose too slowly for a patient who is symptomatic now, although they may follow later as a snack to hold the level. A diet drink contains no sugar at all and treats nothing. Withholding oral intake is correct only when the patient cannot swallow safely or is not alert, which is not the case here.

A charge nurse tells a technician to put a vest restraint on a confused patient who is resting quietly in bed. The technician has never been trained on that device, and no restraint order appears in the record. What should the technician do?

• a.Apply the vest, since a licensed nurse gave the instruction directly
• b.Ask the supervisor to confirm the order and arrange training first✓
• c.Apply the vest now and document it after the order has been entered
• d.Raise all four side rails instead until the paperwork is done

Two things are missing here, and neither is optional: a restraint needs a provider order, and the person applying it must be trained on that specific device, so the technician stops and gets both settled while the patient, who is resting quietly, is in no immediate danger. A direct instruction from a nurse does not create an order or supply training, and an untrained application is how patients are strangled by vest restraints. Documenting after the fact does not cure an application that had no authorization at the time. Raising all four side rails is not a workaround, because that is itself a restraint and needs the same order.

While walking in the hallway, a patient stops, grips his chest, and reports crushing pressure spreading into his jaw. What should the technician do first?

• a.Walk him back to his room at a slower pace and then take vital signs
• b.Offer the antacid at his bedside and look in on him again in ten minutes
• c.Stop the walk, help him sit down, stay with him, and call out for the nurse✓
• d.Coach him to breathe slowly and finish the ordered walking distance

Crushing chest pressure radiating to the jaw is treated as cardiac until proven otherwise, so exertion stops instantly, the patient is helped into a safe position where a collapse would not injure him, and help is summoned while the technician stays at his side. Walking him back to the room, even slowly, keeps demanding work from a heart that may not be getting enough blood, and it leaves him upright in a corridor. Giving any medication, including something as ordinary as an antacid, is outside the technician's scope and delays recognition. Breathing exercises and completing the distance treat this as anxiety, a judgment no technician is in a position to make.

Under the OSHA Bloodborne Pathogens Standard, which measure is an engineering control for preventing needlestick injuries?

• a.Recapping a needle by the one-handed scoop technique
• b.A syringe whose needle retracts into the barrel after use✓
• c.Wearing two pairs of gloves for every venipuncture drawn
• d.Annual bloodborne pathogens training for all clinical staff

Engineering controls are the devices themselves, redesigned so the hazard is isolated or removed from the workplace: retractable needles, self-sheathing lancets, blunting devices, needleless connectors, and sharps containers. The one-handed scoop is the closest competitor here and is genuinely protective, but it is a work practice control, because it changes how a person performs a task rather than changing the device. Training is an administrative control, and gloves are personal protective equipment, which is the last line of defense rather than the first. Ranking these correctly matters because the standard requires employers to use engineering controls first where they exist.

A technician is called away from a hallway workstation where a patient's electronic record is open on the screen, and visitors are seated within view of the monitor. What should the technician do before stepping away?

• a.Turn the monitor so that the screen faces the corridor wall
• b.Ask the visitors seated nearby to move to the waiting area
• c.Minimize the record window and leave the session signed in
• d.Log off the workstation before leaving it✓

A workstation in a patient care area must be logged off or locked whenever it is left unattended, because an open record is reachable by anyone who walks up to it. Minimizing the window or turning the monitor hides the display for a moment but leaves the session running under the technician's own credentials, so the record can be reopened and anything typed there is attributed to the technician. Moving the visitors addresses two people at one moment rather than the exposure itself. Logging off is the step that closes the record to everyone who passes the station.

A technician tells an alert adult patient that a blood pressure reading will be taken. Without speaking, the patient pushes up a sleeve and holds out an arm. What type of consent has the patient given?

• a.Informed consent, because the procedure was explained beforehand
• b.Written consent, because the admission paperwork was already signed
• c.Implied consent, shown by the patient's cooperative action✓
• d.Proxy consent, because a family member is present at the bedside

Consent is implied when a patient's voluntary action shows agreement to a routine, low-risk task that has been explained, such as offering an arm for a cuff. Informed consent is a documented disclosure of risks, benefits, and alternatives obtained by the provider who will perform an invasive or risky procedure, and a routine vital sign does not meet that threshold. The admission paperwork is a general consent to treatment, not the agreement being given at this bedside. Proxy consent applies only when a legally authorized person decides for a patient who cannot decide, which does not describe an alert adult.

A technician finds a printed shift report listing patient names, room numbers, and diagnoses lying on a bench in the public lobby. What should the technician do first?

• a.Report the discovery to a supervisor before handling the printed pages
• b.Leave the report in place so the unit can trace who lost it
• c.Put the report into the recycling bin by the lobby entrance
• d.Pick the report up at once and keep it secured out of public view✓

Information left in a public area keeps being disclosed for as long as it lies there, so the first act is to end the exposure by retrieving the pages and securing them. Notifying the privacy officer or the supervisor follows immediately, but making that call while the report stays on the bench allows the disclosure to continue. Leaving it in place to identify the owner exposes every name on the page to everyone who walks by. A recycling bin is not secure destruction, since the pages remain readable and reachable.

A patient keeps pulling an arm away during a blood pressure check, and the technician says, "Hold still or I will tie your arms to the bed." The technician does not touch the patient. Which term describes this conduct?

• a.Assault, because the threat put the patient in fear of harmful contact✓
• b.Battery, because harmful contact was intended by the threat
• c.False imprisonment, because the patient's movement was being restricted
• d.Negligence, because the patient did not receive reasonable care

Assault is a threat or act that places a person in reasonable fear of harmful or offensive contact, and no touching is required for it, so the threat to tie the patient down is enough on its own. Battery requires that the contact actually occur, which did not happen in this scene. False imprisonment requires that the patient be confined or restrained, and this patient remained free to move. Negligence is a breach of the duty of care that causes harm, which describes a failure to act rather than a spoken threat.

Midway through a 12-lead ECG, a patient who signed the consent form says, "Stop, I have changed my mind, take these off me." What should the technician do?

• a.Stop the tracing and tell the nurse or supervisor✓
• b.Finish the tracing quickly, since the consent form was already signed
• c.Explain that the recording cannot be interrupted once it has started
• d.Continue and ask the family at the bedside to talk with the patient

Consent may be withdrawn at any point, including partway through a procedure, and a signed form does not bind a patient who says stop. The technician removes the electrodes, keeps the patient covered and comfortable, and passes the refusal to the nurse or supervisor so it is documented and the ordering provider is informed. Continuing after consent is withdrawn is unconsented contact and can be charged as battery. Telling the patient that a recording cannot be interrupted is untrue, and having relatives press the patient to go on produces pressure rather than consent.

A 9-year-old child is brought to an outpatient department by an adult neighbor for a procedure that requires consent. Absent an emergency or a specific state-law exception, who may give that consent?

• a.A parent of the child, or a court-appointed legal guardian✓
• b.The neighbor, who brought the child to the appointment
• c.The child, if the child can say what is going to be done
• d.The department physician, acting in the child's best interest

A minor generally cannot give legal consent, and the authority rests with a parent or a court-appointed legal guardian unless the minor is emancipated or a state law lets a minor consent to a specific category of care. An adult who merely accompanies the child gains no legal authority by doing so. A 9-year-old should receive an age-appropriate explanation and may assent to what is about to happen, but assent from a child is not legal consent. A physician may proceed without consent only in a true emergency, when delay would threaten the child's life or health.

A technician posts on a public social media page that a named patient "fakes pain to get drugs," which is untrue. Which term names the false written statement itself?

• a.Slander, because the statement injured the patient's reputation
• b.Fraud, because the statement misrepresented the care that was given
• c.Invasion of privacy, because private facts were made public
• d.Libel, because a false and damaging statement was written and published✓

Libel is defamation in written, printed, or otherwise published form, and a social media post naming a patient that is false and injures reputation meets that definition. Slander is the spoken form of the same tort, so it does not describe a post. Fraud involves deception for gain, such as charting care that was never delivered. Publishing a patient's information is also an invasion of privacy and a privacy-rule violation, but that term names the disclosure rather than the false statement this question asks about.

A technician notices that a coworker on the same shift smells of alcohol and is unsteady while helping transfer a patient from a bed to a chair. What should the technician do?

• a.Take over the transfer and let the coworker rest in the break room
• b.Report the observation to the charge nurse or supervisor✓
• c.Say nothing unless a patient is actually harmed
• d.File a complaint with the state certifying board after the shift

An impaired coworker is an immediate hazard to every patient in that assignment, so the observation goes to the supervisor at once and the coworker is removed from patient care by someone with the authority to do it. Quietly covering the work and sending the coworker to rest leaves an impaired person on the unit and makes the technician part of the risk. Waiting for actual harm abandons the patients being handled right now, and an unsteady transfer can injure a patient in seconds. A certifying board reviews conduct long after the fact and is not the route for a hazard unfolding on the floor.

A competent patient who has no activity restriction says he is going to walk down to the lobby. The technician raises all four side rails and tells him he may not get out of bed. Which term describes this?

• a.False imprisonment, because the patient was confined without an order✓
• b.Battery, because the raised side rails made contact with the patient
• c.Negligence, because the patient's safety needs were not assessed beforehand
• d.Assault, because the patient was told that he could not get up

Confining a competent patient who has no order restricting movement is false imprisonment, and four raised side rails function as a physical restraint whether or not force is used. Battery requires harmful or offensive contact with the patient's body, and raising a rail is not contact with the patient. Assault requires a threat of harm, which is more than a statement that the patient may not get up. Negligence is a failure to provide reasonable care that causes harm, which does not describe movement that was deliberately blocked.

A patient becomes unresponsive after surgery. The chart contains a durable power of attorney for health care naming the patient's sister, and the patient's adult son is at the bedside asking to make the decisions. Who speaks for the patient?

• a.The son, because he is the closest relative present at the bedside
• b.The physician, until the family reaches agreement about the care
• c.The sister and the son jointly, since both are immediate family
• d.The sister, because the patient appointed her to decide when he could not✓

A durable power of attorney for health care names the person the patient chose to decide once the patient can no longer speak, and that appointment controls over the informal standing of relatives at the bedside. The son may be a closer relative, but a health care agent is selected by the patient and takes precedence over the usual surrogate order. A physician recommends treatment and does not become the decision maker while a valid agent is available. Dividing the decision between two relatives has no legal basis, and disagreement is worked through with the agent, the care team, and if needed the ethics committee.

A patient with a valid do-not-resuscitate order in the chart is found unresponsive, pulseless, and not breathing. What should the technician do?

• a.Begin chest compressions until the code team reaches the room
• b.Give rescue breaths only, since the order applies to compressions
• c.Summon the nurse at once and withhold resuscitation✓
• d.Ask the relatives at the bedside whether they want CPR started

A valid do-not-resuscitate order directs that resuscitation, including chest compressions, rescue breathing, defibrillation, and intubation, not be started when the heart or breathing stops. The technician still calls the nurse immediately so the patient is assessed, the event documented, and comfort measures and family support provided, because the order stops resuscitation rather than care. Starting compressions or rescue breaths would act against the order and against the wishes the patient recorded. Relatives at the bedside cannot set aside a valid order in the moment; a change is made through the provider who wrote it.

A technician's personal beliefs conflict with an assignment to assist with a procedure scheduled later in the shift. What is the appropriate action?

• a.Assist with the procedure and tell the patient it violates those beliefs
• b.Tell the supervisor in advance so the assignment can be reassigned✓
• c.Leave the unit at the time the procedure is set to begin
• d.Trade the assignment with a coworker without informing anyone

A conflict of conscience is raised with the supervisor in advance, while there is still time to assign another staff member, so the patient's care goes forward without interruption. Voicing disapproval at the bedside burdens the patient with the technician's beliefs and breaches the code of conduct. Walking off the unit when the procedure is due is abandonment and puts every patient in that assignment at risk. Swapping privately with a coworker leaves the supervisor holding an assignment sheet that does not match who is actually delivering the care.

At discharge, a grateful patient presses a fifty-dollar bill into a technician's hand as thanks for the care given during the stay. What should the technician do?

• a.Accept the money and divide it among the staff on the unit
• b.Accept the money so the patient does not feel that thanks were refused
• c.Decline politely and explain that facility policy forbids it✓
• d.Accept the money and report it to the billing office

Facilities bar staff from accepting money or valuable gifts from patients because such a payment creates a conflict of interest and the appearance that attention can be bought. The technician declines warmly, explains the policy, and can name the routes the facility does allow, such as a note of thanks to management. Sharing the cash with the unit or routing it to billing does not cure the conflict, since the payment was still handed to a caregiver for care. Accepting it to spare the patient's feelings puts the technician's comfort ahead of a policy that protects every patient on the unit.

A technician sees another staff member slap the hand of a resident who is reaching for the call light, then walk out of the room. What should the technician do first?

• a.Stay with the resident and check for injury✓
• b.Tell the supervisor about the incident at the end of the shift
• c.Ask the staff member privately to explain what happened
• d.Chart the observation before taking any other step

Striking a patient is abuse, and the first duty runs to the resident: stay in the room, look for injury, and provide reassurance before anything else is done. Reporting is mandatory and follows immediately, but holding the report until the shift ends leaves an unassessed injury and keeps the staff member in patient care areas for hours. Questioning the staff member is an investigation, which belongs to the facility and the state agency rather than to the technician, and it gives the account time to change. Documenting matters, but a chart entry does nothing for a resident who may be hurt at this moment.

A patient asks a technician for a copy of the notes in her own medical record. What should the technician do?

• a.Explain that only the treating physician may release the record
• b.Print the notes at the unit workstation and hand them to her
• c.Direct the request to the medical records department✓
• d.Explain that the record is facility property and stays in the chart

Patients have a right of access to their own records, and the request is met through the health information management or medical records department, which verifies identity, logs the disclosure, and releases the material within the required time frame. Printing pages at a unit workstation bypasses that process, leaves the disclosure unlogged, and may hand over material the technician has no authority to release. Saying that only the physician may release a record is a common misconception, since the right of access does not depend on the physician's approval. The physical chart is facility property, but the information belongs to the patient, who may inspect it and obtain a copy.

A patient tells a technician that he wants to file a formal complaint about the care he received during the night shift. What should the technician do?

• a.Ask the patient to wait until discharge so the matter can be reviewed then
• b.Explain that concerns like this must go to the physician first
• c.Enter the complaint in the chart and take no further step on it
• d.Explain the facility's grievance process and pass the complaint on✓

Patients have the right to voice a grievance without fear of consequences, so the technician listens, explains how the facility's grievance process works, and routes the concern to the nurse or patient advocate who logs it formally. Asking the patient to hold the complaint until discharge discourages him and delays review of care that is still being delivered. Requiring the concern to go to the physician first invents a barrier the grievance process does not contain. A chart entry alone records that the patient spoke but does not start the review he asked for.

A patient asks a technician to fax a copy of her laboratory results to her attorney. What is required before those results may be released?

• a.Nothing further, because the patient is asking for her own information
• b.The general consent for treatment that the patient signed at admission
• c.A written statement from the attorney confirming that he represents her
• d.A signed authorization from the patient for the release✓

Disclosure to a third party such as an attorney requires the patient's signed authorization, which names who may receive the information, what is being released, and when the permission expires. A spoken request is not enough for a disclosure outside treatment, payment, and health care operations, even though the information concerns the patient herself. The general consent signed at admission covers treatment and routine operations, not release to an outside party. A confirmation letter from the attorney establishes who he is but never substitutes for the patient's own written permission, and the release itself is handled by medical records rather than at the bedside.

A technician realizes that a discharge summary belonging to one patient was handed to a different patient, who has already read part of it. Within the facility, to whom should this be reported?

• a.The information technology help desk that maintains the record system
• b.The federal Office for Civil Rights, which enforces the privacy rule
• c.The unit clerk who printed the discharge paperwork
• d.The facility's privacy officer, as facility policy directs✓

A staff member who discovers that protected health information reached the wrong person reports it internally, to the privacy officer or through the channel facility policy names, so the event is investigated and a breach risk assessment is completed. The facility, not the individual technician, is the party that notifies the Office for Civil Rights and the affected patient when notification is required. The help desk resolves system faults and has no role in a paper disclosure or its analysis. Telling only the clerk who printed the paperwork keeps the event off the record the facility is obligated to maintain.

A technician wants a patient to describe how he has been sleeping since he was admitted. Which question is open-ended?

• a.What has your sleep been like since you came into the hospital?✓
• b.What time did you finally fall asleep here last night?
• c.Which would help more tonight, a blanket or a fan?
• d.How many times did the hallway noise wake you last night?

An open-ended question cannot be closed out with a word or a number, so it invites the patient to describe the problem in his own terms and often brings out what no checklist would ask about, such as pain, worry, or a roommate's television. Asking what his sleep has been like since admission leaves the whole answer to him. A question that asks what time he fell asleep, or how many times he woke, still asks for one fact and ends there. Offering a choice between a blanket and a fan hands the patient two ready-made answers instead of collecting his own. Beginning with a question word therefore does not by itself make a question open-ended.

A patient who has just learned she will be discharged to a nursing home stops talking and stares out the window. Which response by the technician best uses therapeutic silence?

• a.Ask the patient why the move upsets her this much
• b.Sit quietly with the patient and wait for her✓
• c.Say that most people settle in within a week or two
• d.Move on to what the patient chose for her lunch

Silence is an active technique: staying present without speaking gives the patient time to organize a painful thought and signals that the technician is willing to hear it. Asking her why she is upset demands that she justify a feeling and usually makes her defend herself instead of talk. Predicting that she will settle in is false reassurance, which closes the subject by answering a worry the patient has not yet described. Turning to the lunch order changes the subject and tells her the topic is unwelcome.

A patient becomes tearful and says that her husband died on this same unit last year. Which response by the technician shows empathy rather than sympathy?

• a.Being back on this unit must bring a great deal of that up for you✓
• b.I felt the same way when my own father died here two years ago
• c.I am so sorry for you; that is a terrible thing to go through
• d.Try not to dwell on it; today is about getting you well

Empathy names what the patient appears to be feeling and leaves the door open for her to say more, keeping the focus on her experience. Sympathy expresses the technician's own pity, and the statement of sorrow does that; it is kind, but it tends to end the conversation rather than open it. Recounting the technician's father moves the subject to the technician and quietly asks the patient to listen. Telling her not to dwell on the loss minimizes it and teaches her that grief is not welcome here.

A patient recovering from a stroke has expressive aphasia: he understands what is said to him but cannot find the words to answer. Which approach should the technician use?

• a.Speak in a much louder voice and exaggerate each word
• b.Finish his sentences for him so he is not frustrated
• c.Ask questions he can answer yes or no, and give him time to reply✓
• d.Direct the questions to the family member at the bedside

Expressive aphasia is a problem producing language, not hearing or understanding it, so questions with a short yes or no answer plus unhurried waiting let the patient succeed at communicating. Raising the volume treats him as though he were deaf and can read as anger. Finishing his sentences is meant kindly but takes the work of speech away from him and often guesses wrong. Redirecting questions to the family bypasses a patient who understands everything being said about him.

A patient whose discharge has been delayed is standing beside his bed shouting and pointing at the technician. He has made no threat, and the path to the door is clear. What should the technician do first?

• a.Step into the hall and ask the supervisor to come speak with him
• b.Move in close and put a hand on his shoulder to settle him
• c.Speak in a calm, even voice and let him say what is wrong✓
• d.Explain that shouting at the staff is not allowed here

A patient who is venting anger but has not threatened anyone is still reachable, and a calm voice, an unhurried pace, and permission to finish the complaint are what lower the intensity. Leaving to bring the supervisor abandons the escalation at the point where it is easiest to defuse, and the technician can call for help afterward if the behavior changes. Touching an agitated person, even gently, is frequently read as restraint and raises the risk of a strike. Quoting the unit rule turns the exchange into an argument the technician cannot win.

Which notation in a patient's record appears on the Joint Commission 'Do Not Use' list because it is easily misread?

• a.0.5 mg written with a zero in front of the decimal point
• b.A dose written as 1.0 mg with a zero after the decimal✓
• c.mL written as the abbreviation for milliliters
• d.bid written for an entry charted twice a day

A trailing zero is prohibited because a faint or smudged decimal point turns 1.0 mg into 10 mg, a ten-fold error. The leading zero is the opposite case: it is required, since .5 mg read without the point becomes 5 mg. Writing out mL is standard and is not restricted. The abbreviation bid is in ordinary use; the daily-frequency abbreviations on the prohibited list are the ones built on q.d. and q.o.d., which are confused with each other and with qid.

A provider telephones the unit and begins giving the technician a telephone order to change a patient's IV rate. What should the technician do?

• a.Write the order down and ask the supervisor to sign it
• b.Ask the provider to hold for the nurse✓
• c.Repeat the order back and enter it in the chart
• d.Tell the provider to call again at shift change

Accepting a telephone or verbal order requires a license, so the technician's job is to get the licensed nurse on the line without delay. Writing the order down and having it signed later still means an unlicensed person received and transcribed it, and the signature does not repair that. Reading the order back is the correct read-back step for whoever is permitted to take it, but it does not make the technician permitted. Sending the provider away until shift change delays a change to an infusion the patient is receiving now.

Late in the afternoon a patient with moderate dementia becomes tearful and insists that she has to go home and cook supper for her small children. What should the technician do?

• a.Remind her that her children are grown and that she lives here now
• b.Tell her she sounds like a busy mother and offer to fold towels together✓
• c.Tell her that the children are safe and that the bus will come later
• d.Leave her alone in her room until the restlessness passes

Validation accepts the emotion behind the statement rather than the facts of it, and pairing it with a familiar, purposeful task redirects the restlessness that often builds in the late afternoon. Correcting her about her children makes her hear that her family is gone, and she is likely to grieve it again the next time she asks. Inventing a bus is a lie that buys ten minutes, then fails when no bus arrives and she has one more reason to distrust the staff. Leaving her alone removes supervision from a tearful patient at exactly the hour she is most likely to try to leave.

A nurse is deciding whether a particular task may be delegated to a technician. Which of the following is one of the five rights of delegation?

• a.The right diagnosis, so that the task fits the medical problem
• b.The right documentation, so that the entry matches the order
• c.The right dose, so that the amount is checked before the task
• d.The right direction and communication about the task✓

The five rights of delegation are the right task, the right circumstance, the right person, the right direction and communication, and the right supervision and evaluation. Direction and communication is the step where the nurse states exactly what is to be done, what to report back, and when. Diagnosis is not a delegation right at all, since diagnosing is outside the technician's role in every setting. Dose belongs to medication administration, and documentation is a separate duty that follows the task rather than governing whether it may be handed off.

Walking past a room, a technician sees a confused patient who is on fall precautions swinging one leg over the side rail. No one else is in the room. What should the technician do first?

• a.Go down the hall and tell the supervisor what the patient is doing
• b.Raise the remaining side rails so the patient cannot get out
• c.Offer to bring him a drink and step out to fetch it
• d.Stay at the bedside, guide his leg back in, and call out for help✓

The patient is seconds away from a fall, so the technician stays within arm's reach, guides the leg back onto the bed, and calls out so that help comes to the room instead of leaving to go find it. Walking down the hall to report the behavior leaves the fall unattended, and a report made after the patient is on the floor is a report about an injury. Raising all of the side rails to hold a patient in bed is a restraint that requires a provider's order under federal hospital and long-term care rules, and a confused patient determined to get up climbs over the rails and falls from a greater height. Leaving to fetch a drink is the same abandonment dressed up as care. Once help is at the bedside, the event and the patient's condition are reported to the nurse and documented according to facility policy.

A technician reads the word 'dysphagia' in a patient's care plan. What does that term describe?

• a.Difficulty producing or understanding speech
• b.Difficult or labored breathing when at rest
• c.Difficulty swallowing foods or liquids✓
• d.Painful or difficult passing of urine

The prefix dys- means difficult or painful, and the suffix -phagia refers to eating and swallowing, so dysphagia is trouble swallowing and is the reason a patient may be on thickened liquids or need to sit fully upright to eat. The near-twin is dysphasia, with -phasia for speech, which is why the two are so often confused on a care plan. Labored breathing is dyspnea, from -pnea for breathing. Painful urination is dysuria, from -uria for urine.

A patient returns to the unit after a colostomy. Based on the suffix in that word, what was done?

• a.An opening was created into the colon✓
• b.A section of the colon was cut into and then repaired
• c.A section of the colon was surgically removed
• d.The inside of the colon was examined with a scope

The suffix -ostomy means a surgically created opening, or stoma, so a colostomy brings the colon to the surface of the abdomen and stool drains into an appliance the technician may be asked to empty and measure. The suffix -otomy means only an incision into something, as in tracheotomy. The suffix -ectomy means excision, so a colectomy is removal of part or all of the colon. Visual examination carries -oscopy, as in colonoscopy, and involves no permanent opening.

A nurse asks a technician to discontinue a patient's peripheral IV catheter. The technician did this routinely for an employer in another state but has not been checked off on it at this facility. What should the technician do?

• a.Remove it, because the nurse's license covers a task she delegates
• b.Remove it, since he was trained on the procedure at his last job
• c.Refuse the task and document the refusal in the patient's chart
• d.Ask the supervisor whether this task is within his scope at this facility✓

What a technician may do is set by the state, by facility policy, and by the certification and competency verification he actually holds, and none of those transfer with him from another employer. Verifying with the supervisor settles the question in a minute and produces either a competency check or a different assignment. Prior training elsewhere establishes skill, not authorization. The idea that the delegating nurse's license extends over the technician is a common misreading: the nurse remains accountable for the delegation, but she cannot delegate a task the technician is not permitted to perform. Flatly refusing without asking leaves the patient's IV in and puts a staffing dispute into a record that is meant for patient care.

A technician who is leaving at the end of her shift asks a coworker to chart the bath and linen change that she performed. What should the coworker do?

• a.Decline, since each person charts the care she gave✓
• b.Chart it and note that the other technician did the care
• c.Chart it under the other technician's login before leaving
• d.Chart it as a late entry once the details are confirmed

The record is a legal account of who did what and who observed it, so the only person who can document that bath is the technician who gave it, and she should complete it before she leaves. Entering it under a coworker's login is falsification and destroys the audit trail, which records the login rather than the hands. A late entry is a legitimate tool, but it belongs to the person who provided the care and is used when her own documentation was delayed. Adding a note that names the other technician still puts care the writer did not perform or witness into the writer's entry.

A technician finishes a round of vital signs and observations at 1500. Which finding should be reported to the nurse right away rather than saved for the end-of-shift report?

• a.A patient reports new shortness of breath while at rest✓
• b.A patient's blood pressure reads 134/86 mm Hg on a second check
• c.A patient walked half of the hallway instead of the whole hall
• d.A patient's oral temperature is 99.1°F at rest

New shortness of breath at rest is a change in condition that the nurse has to assess now, because the causes range from anxiety to a pulmonary embolus and the technician cannot tell them apart. A reading of 134/86 mm Hg is stage 1 hypertension under the 2017 ACC/AHA categories, which begin stage 1 at 130-139 systolic or 80-89 diastolic; it is abnormal and must be recorded and passed on, but it is not an emergency on its own. An oral temperature of 99.1°F sits inside the usual range of about 97.6-99.6°F. A shortened walk is documented and reported at the end of the shift.

For several shifts a technician has seen the same coworker leave call lights ringing while patients wait for help. The technician has already raised it with the coworker directly and nothing has changed. What should the technician do next?

• a.Report the pattern to the charge nurse or supervisor✓
• b.Write a note about each unanswered light in the patients' charts
• c.Ask the other technicians whether they have noticed the same thing
• d.Answer those call lights herself and let the matter drop

A direct conversation is the right first move and it has been tried, so the next step in the chain of command is the person responsible for the assignment and for the patients who are waiting. The patient record documents that patient's care, not a coworker's performance, and putting staffing complaints in it exposes the chart in ways that help no one. Polling other technicians spreads the story sideways to people with no authority to correct it. Quietly covering the lights protects the coworker, hides the pattern from the one person who can fix it, and leaves the next patient waiting.

A patient who speaks limited English is being prepared for a procedure, and his 12-year-old daughter offers to interpret for him. What should the technician do?

• a.Ask the supervisor whether the daughter may interpret today
• b.Let the daughter interpret, since she knows his history
• c.Use simple English and hand gestures with the patient
• d.Arrange a qualified interpreter through the facility✓

Facility policy and federal language-access requirements expect a trained interpreter, in person or by phone or video, because clinical terms have to survive translation, the patient's information stays confidential, and a child is not made responsible for delivering frightening news to a parent. A minor who is fluent is still not qualified, and she may soften or edit what she hears. Routing the question through the supervisor delays care and cannot turn an untrained child into a qualified interpreter. Gestures and simple English cannot carry what a patient needs to know before a procedure.

A technician is walking a patient who is blind from her room to the shower room down the hall. What is the correct technique?

• a.Take hold of her upper arm and steer her from behind down the hall
• b.Speak loudly as they walk so that she can follow his voice
• c.Push her in a wheelchair because the hallway is crowded
• d.Offer his arm for her to hold and walk half a step ahead of her✓

In sighted-guide technique the patient holds the technician's arm just above the elbow and follows about half a step behind, so she feels every turn, slope, and stop through his arm before she reaches it. Taking her arm and pushing her from behind reverses that: she gets no advance warning and loses control of her own pace. Volume is not the barrier, and shouting at a blind patient in a hallway is undignified and announces her business to everyone. Putting an ambulatory patient in a wheelchair for the staff's convenience takes away mobility she has and did not ask to give up.

A technician draws the lavender-top tube before the green-top tube on a patient whose electrolytes were ordered. Which chemistry result is most likely to be falsely elevated by carryover of the lavender tube's additive?

• a.Calcium, because carryover EDTA releases calcium bound to plasma proteins
• b.Potassium, because the tube's own additive is a potassium salt of EDTA✓
• c.Sodium, because the EDTA in a lavender tube is supplied as a sodium salt
• d.Chloride, because EDTA contributes chloride ions to the plasma

Lavender-top tubes in United States laboratories are filled with dipotassium or tripotassium EDTA, so even a trace of additive dragged from one stopper to the next on the needle adds potassium to the chemistry specimen and can push a normal result into the critical range. EDTA moves calcium and magnesium the other way: it chelates those ions inside the tube, which lowers the measured value, and it does not free calcium that is bound to plasma proteins. Sodium EDTA formulations exist but are not what is packaged in a routine lavender tube, and EDTA contributes no chloride at all. This carryover risk is the reason the EDTA tube sits near the end of the CLSI order of draw, after the heparin tube, rather than near the front.

A technician is using a winged (butterfly) collection set, and the only tube ordered is a light blue sodium citrate tube for a PT/INR. What should the technician do first?

• a.Draw the citrate tube first and then draw a second citrate tube to make up any missing volume
• b.Choose a smaller-volume citrate tube so that the short fill from the tubing still meets the ratio
• c.Draw a discard tube first to fill the air space in the tubing, then draw the citrate tube✓
• d.Draw the citrate tube and reseat it on the holder to finish the fill

The tubing of a winged set holds a column of air, and the first tube on the line loses that much of its vacuum draw, so a citrate tube collected first fills short. Drawing a discard tube first, which does not need to be filled completely, primes the tubing so the citrate tube reaches its fill line and holds the required nine parts blood to one part citrate. Splitting the volume between two citrate tubes does not fix anything, because each tube then holds a full dose of citrate for a partial blood volume. Switching to a smaller tube does not help either, since every citrate tube is calibrated to its own fill line, and pulling a partly filled tube off and reseating it wastes the remaining vacuum instead of restoring it.

A light blue sodium citrate tube collected for a PT and aPTT is filled only about two-thirds of the way to its fill line. Why does the laboratory reject it?

• a.Citrate is in excess for the plasma present, so it binds extra calcium and falsely prolongs clotting✓
• b.The lower fill lets the specimen clot inside the tube, because trapped air dilutes the citrate present
• c.The short draw concentrates the platelets, which falsely shortens the measured clotting times
• d.The reduced volume leaves too little plasma for the analyzer to aspirate at all

A light blue tube is manufactured for a fixed 9:1 ratio of blood to 3.2 percent sodium citrate, and the citrate works by binding the calcium a specimen needs to clot. When the tube is only about two-thirds full, the same dose of citrate is spread across less plasma, so more calcium stays bound when the laboratory adds calcium back to start the test, and the PT and aPTT read longer than the patient's true values. That is a falsely abnormal result that can lead to a real change in anticoagulant dosing, which is why underfilled citrate tubes are rejected rather than run. Air does not dilute citrate, extra citrate lengthens rather than shortens clotting times, and analyzers can usually aspirate the small volume present, so volume alone is not the reason for rejection.

By what mechanism does the additive in a lavender-top tube keep the specimen from clotting?

• a.It neutralizes thrombin directly, in the way an antithrombin agent interrupts the clotting cascade
• b.It coats the cells with a thin film that keeps the platelets from sticking to one another
• c.It chelates calcium, removing the ion that the coagulation cascade needs in order to proceed✓
• d.It blocks the enzymes red cells use to break down glucose, which also stops clotting

EDTA is a chelating agent: it binds free calcium ions in the specimen, and without calcium several steps of the coagulation cascade cannot proceed, so the blood stays liquid. Because EDTA preserves cell size and shape well, it is the additive of choice for a complete blood count and a manual differential. Neutralizing thrombin is how heparin works through antithrombin, not how EDTA works, and no routine additive coats cells in a film to block platelet adhesion. Blocking the enzymes of glycolysis describes sodium fluoride in a gray-top tube, which preserves glucose but is not what keeps an EDTA specimen from clotting.

A chemistry test must be performed on plasma rather than serum. How does plasma differ from serum?

• a.Plasma comes from an anticoagulated tube and still contains fibrinogen and the clotting factors✓
• b.Plasma is the fluid left after a tube has clotted fully and then been spun in a centrifuge
• c.Plasma still contains the red cells and white cells, and serum has had those cells removed
• d.Plasma can be obtained only from arterial blood, while serum is obtained from venous blood

Plasma is the liquid portion of blood collected into an anticoagulant tube and spun before it can clot, so fibrinogen and the other clotting factors remain in it. Serum is what is left after blood in a nonadditive or clot activator tube has clotted, which consumes fibrinogen and leaves it behind in the clot, so serum is the fluid after clotting rather than plasma. Because no volume is lost to a clot, an anticoagulated tube also yields more plasma than an equal draw yields serum, which matters when several tests share one tube. Neither fluid contains red or white cells once the tube is centrifuged, and both plasma and serum are routinely obtained from ordinary venous draws.

A prescriber orders a lithium level on a patient taking lithium carbonate. Which collection tube is unacceptable for this specimen?

• a.A green-top tube containing lithium heparin, because that additive is itself a lithium salt✓
• b.A gold-top serum separator tube, because the gel barrier absorbs lithium during centrifugation
• c.A plain red-top tube with no additive, because serum cannot be used for drug levels
• d.A green-top tube containing sodium heparin, which is not a true anticoagulant

Lithium heparin adds lithium to the specimen, so a level drawn into that tube can read far above the patient's real concentration and prompt a dose change the patient does not need. A lithium level is collected in a plain red-top serum tube or, where the laboratory specifies plasma, in sodium heparin, so both of those choices are acceptable rather than unacceptable. The same logic runs the other way for electrolytes: a sodium level should not be drawn in sodium heparin, and lithium heparin is preferred there. The gel in a serum separator tube does not strip lithium from the sample, and sodium heparin is a genuine anticoagulant that works through antithrombin.

A technician collects a total and direct bilirubin on a newborn who is receiving phototherapy. What should the technician do with the tube immediately after the collection?

• a.Place the capped tube upright in a slurry of ice and water and walk it to the laboratory
• b.Wrap the tube in foil or place it in an amber transport tube, then send it to the laboratory promptly✓
• c.Ask the supervisor to have the tube warmed to 37 degrees Celsius for transport
• d.Leave the tube at the nurses' station for the next scheduled courier pickup round

Bilirubin breaks down when it is exposed to light, and a specimen left under room lighting or a phototherapy lamp can lose a clinically meaningful amount of its measurable bilirubin within an hour. Shielding the tube in foil or an amber transport container and delivering it without delay preserves the value the provider will use to decide whether this newborn needs more aggressive treatment. Chilling in an ice slurry is the handling requirement for specimens such as ammonia and lactic acid, and holding a specimen at 37 degrees Celsius is what cold agglutinin and cryoglobulin testing requires; neither one protects bilirubin from light, and warming offers it no protection at all. Holding the tube for a routine courier run adds exactly the delay that degrades it. Light protection for bilirubin is standard documented handling, with the specific transport container set by facility procedure.

Which specimen must be transported to the laboratory chilled in a slurry of ice and water?

• a.A potassium level, because cooling keeps the cells from releasing their potassium into the plasma
• b.A CBC in a lavender tube, because cooling preserves the cells for the differential
• c.An ammonia level, because cells keep generating ammonia in the tube at room temperature✓
• d.A glucose in a gray tube, because the fluoride works only at refrigerator temperature

Ammonia rises in a collected specimen as blood cells continue to metabolize, so the tube goes into an ice and water slurry and travels to the laboratory immediately; lactic acid and blood gases are handled the same way. Potassium is the trap in this group, because chilling does the opposite of what the tempting answer claims: cold blocks the cell membrane pump, potassium leaks out of the red cells, and the reported value comes back falsely high, so a potassium specimen is kept at room temperature. A CBC is also held at room temperature, since chilling distorts the cells the analyzer is counting and sizing. Sodium fluoride inhibits glycolysis at room temperature and needs no ice to do its job.

A gold-top serum separator tube has just been collected for a chemistry panel. What must happen before that tube is placed in the centrifuge?

• a.The specimen has to clot undisturbed at room temperature for about 30 minutes after mixing✓
• b.The stopper has to come off so that pressure cannot build inside the tube as it spins
• c.The tube has to be chilled so the gel barrier can form completely during the spin
• d.The tube has to be balanced against a second tube ordered for the same test

A serum tube must clot completely before it is spun, which takes roughly 30 minutes at room temperature for a gold-top tube with a clot activator; spinning early leaves fibrin strands that form a latent clot in the serum and can foul the analyzer or force a redraw. Stoppers stay on during centrifugation, because removing them creates an aerosol of blood and lets the specimen evaporate. Chilling is not part of forming the gel barrier and would slow the clotting the tube depends on. Tubes are balanced by matching size and volume across from one another, not by matching the test that was ordered, and a technician never opens a centrifuge lid until the rotor has stopped on its own.

What role does the sodium fluoride in a gray-top tube play in the specimen?

• a.It serves as the anticoagulant, binding calcium so that the specimen stays liquid in the tube
• b.It preserves the sample by killing the bacteria that would otherwise consume the glucose
• c.It inhibits glycolysis, so that the cells in the tube cannot go on consuming the glucose present✓
• d.It separates the plasma from the cells during the spin, the way a gel barrier does

Sodium fluoride is an antiglycolytic agent: it blocks an enzyme step in glycolysis so that the red cells and white cells in the tube stop consuming glucose after the draw, which preserves the value the laboratory reports. Without it, glucose in a collected specimen falls measurably every hour at room temperature, so a delayed sample can read low enough to look like a normal result in a diabetic patient. The anticoagulant work in that tube is done by the potassium oxalate paired with the fluoride, which is what binds the calcium, so crediting the fluoride with keeping the specimen liquid confuses the two additives. Fluoride is not an antibacterial preservative in this setting, and only centrifugation and a gel barrier separate plasma from cells.

The date of birth printed on a requisition does not match the date of birth on the inpatient's armband. What should the technician do?

• a.Correct the requisition at the bedside once the patient has confirmed the right birth date
• b.Draw the specimen and label the tubes with the date of birth printed on the requisition
• c.Draw the specimen and label the tubes using the birth date shown on the armband
• d.Stop and report the discrepancy to the nurse or supervisor before collecting anything✓

Two identifiers must agree across the requisition, the armband, and the label before any tube is filled, and a mismatch means the technician cannot yet prove which patient the order belongs to. Collecting anyway and choosing one source over the other simply moves the error onto the specimen, where it can put one patient's results in another patient's chart, and correcting a requisition from what a patient says is outside the technician's role and does not resolve where the error came from. The right move is to leave the order uncollected, report the discrepancy so nursing or the ordering area can reconcile the record, and draw only after the two identifiers match. Nothing about this delay harms the patient, which is what separates it from a situation that demands immediate action.

Which set of elements must appear on a blood specimen label before the tubes leave the bedside?

• a.The patient's full name and identification number, the room number, and the ordering provider's full name
• b.The patient's full name and date of birth, the name of the test, and the courier's pickup time
• c.The patient's full name and record number, the date and time of collection, and the collector's initials✓
• d.The patient's full name, the diagnosis being investigated, and the tube's expiration date

A specimen label has to carry the patient's full name, a unique identification number such as the medical record number, the date and time the specimen was collected, and the initials or identification of the person who collected it. Those four elements let the laboratory tie the tube to one patient and let anyone reviewing a result know when the sample was taken and who is accountable for it, which is why they are checked at the bedside rather than at the workstation. A room number changes when a patient is moved and identifies a bed rather than a person, so it can never stand in for the identification number. The courier's pickup time, the working diagnosis, and the tube's expiration date belong to other records and have no place on the label.

An inpatient is confused and cannot state a name or a date of birth. How should the technician confirm identity before drawing the specimen?

• a.Ask the patient's roommate to confirm the name and then compare it with the requisition
• b.Use the room and bed assignment on the printed collection label to identify the patient
• c.Match the armband to the requisition and have the nurse confirm the identity✓
• d.Draw the specimen first and have the nurse verify identity when the labels are applied

When a patient cannot participate in identification, the attached armband becomes the primary identifier and it must be compared element by element against the requisition, with a caregiver such as the assigned nurse or a family member at the bedside confirming that this is the right patient. A roommate is not an authorized source of another patient's identity, and a room and bed assignment is not an identifier at all, since patients are moved and beds are reassigned during a stay. Labeling after the fact, away from the bedside, is how specimens get switched, so the tubes are labeled at the bedside once identity is settled. The verification and the draw happen in that order, not the reverse.

A blood specimen is collected for a pre-employment drug screen. Which handling requirement applies here that does not apply to a routine chemistry specimen?

• a.The specimen has to be divided into two tubes so a second laboratory can repeat the test
• b.The specimen has to be centrifuged at the collection site before it leaves the room
• c.A chain-of-custody form has to record every person who handles the specimen and each transfer✓
• d.The specimen has to be labeled with the employer's account name in place of the patient's

Forensic and employment testing is defensible only if the specimen can be tracked from the donor to the analyzer with no unexplained gap, so a chain-of-custody form travels with it and each person who takes possession signs and dates the transfer. The specimen is sealed with tamper-evident tape in the donor's presence and is never left unattended, and the technician's signature on that form is a legal statement about what was collected. Splitting the sample and spinning it at the collection site are not what makes a specimen forensic, and neither one preserves the custody record. The label still carries the donor's own identifiers, since replacing them with an employer's account name would destroy the identification the chain of custody exists to protect.

A requisition lists a test code the technician does not recognize, and the department's collection manual shows no tube for that code. What should the technician do?

• a.Draw a gold-top serum tube, since the large majority of chemistry tests are run on serum
• b.Draw one tube of every stopper color available so the laboratory can pick the right one
• c.Collect nothing and send the requisition back to the unit clerk to be entered again later
• d.Ask the laboratory or the supervisor which tube this test requires before drawing✓

The tube a test requires is a laboratory specification, and when the requisition and the collection manual do not settle it, the technician confirms the requirement before the needle goes in rather than guessing at it. Choosing a serum tube because most chemistry runs on serum sends the patient for a second stick whenever the assay turns out to need plasma or whole blood. Drawing a tube of every color takes blood the patient does not need to give and still may miss a specimen with a special container or handling requirement. Returning the requisition without collecting delays care for an order that is probably valid and simply needs a tube identified, which one telephone call accomplishes.

The laboratory reports that a lavender-top tube sent for a CBC contains a clot. What should the technician do?

• a.Recollect the specimen in a new lavender tube and mix it right after the draw✓
• b.Ask the laboratory to report the platelet count alone, since a clot will not change it
• c.Invert the original tube ten more times to break the clot up and resend the specimen
• d.Send a green-top heparin tube instead so that this specimen cannot clot a second time

A clot in an EDTA tube traps platelets and white cells, so every cell count from that specimen reads falsely low and the laboratory cannot correct for it; the only remedy is a fresh draw into a new lavender tube, mixed by gentle inversion immediately after collection so the additive reaches the blood before clotting starts. The platelet count is in fact the value most damaged by a clot, since platelets are consumed first, so reporting it alone would be worse than reporting nothing. Breaking up a clot after the fact does not return the trapped cells to suspension and adds hemolysis on top of the original problem. Heparin is not an acceptable substitute for a CBC, because it distorts the white cell and platelet appearance on the stained smear.

A technician is sent to collect a CBC. The patient's left arm has an arteriovenous fistula used for dialysis, and an IV is infusing in the right forearm. The requisition gives no site instruction. What should the technician do?

• a.Ask the nurse or the supervisor how to proceed before choosing a site✓
• b.Draw from a hand vein below the running IV after stopping the infusion
• c.Apply the tourniquet above the fistula and use the cephalic vein there
• d.Use the fistula arm, since the vessels there fill quickly and stay firm

Both arms carry a restriction the technician cannot lift alone, so the draw stops until someone with the authority to decide is involved. A dialysis fistula is off limits for venipuncture anywhere in that limb, above or below it, because a puncture can damage the access the patient's dialysis depends on and can bleed heavily. Drawing distal to an infusion after it has been stopped for two minutes is a real technique, but stopping an IV is the nurse's action and not the collector's. Using the fistula because it fills well is exactly the reasoning that destroys an access.

The basilic vein is ranked as the last choice among the antecubital veins for a routine venipuncture. Which anatomy explains that ranking?

• a.It runs directly over the radial artery and a branch of the ulnar nerve
• b.It rolls away from the needle far more readily than the other antecubital veins
• c.The brachial artery and the median nerve lie immediately beneath it✓
• d.It sits deeper than the cephalic vein and can rarely be palpated at all

The basilic vein lies on the medial, little-finger side of the antecubital fossa, and the brachial artery and the median nerve run close underneath it, so a needle that goes too deep or wanders can strike an artery or a nerve. That injury risk, not technical difficulty, is what puts it behind the median cubital and the cephalic. The basilic does tend to roll, but rolling alone would only make it harder to hit, not dangerous. The radial artery runs on the thumb side of the wrist, nowhere near it, and the basilic is often easy to see and palpate, which is precisely why inexperienced collectors reach for it.

A technician inserts the needle and engages the tube, but no blood appears. Palpating above the needle finds the vein lying clearly to the side of the needle shaft. What should the technician do?

• a.Redirect the needle sideways beneath the skin until it enters the vein
• b.Remove the needle and restart at another site with fresh equipment✓
• c.Advance the needle further along its present path to reach the vessel
• d.Seat a fresh tube on the holder, since the first tube may have no vacuum

Palpation has already answered the question: the needle is beside the vein rather than in it, so this attempt is over and the next one begins with a new needle and a new site. Moving the needle laterally under the skin is probing, which is painful and can lacerate the vein or contact a nerve, and it is outside accepted technique. Pushing straight ahead only drives the needle deeper alongside the vessel. A tube that has lost its vacuum is a genuine cause of no flow and changing tubes is worth doing when the needle is seated in a vein, but that is not the situation here.

During a fingerstick the technician wipes away the first drop of blood with clean gauze before beginning to collect. What is the reason for discarding that drop?

• a.It is the richest drop in red cells and would falsely raise the hemoglobin
• b.It is diluted by tissue fluid and by any alcohol left on the skin✓
• c.It carries skin bacteria that would contaminate the microcollection tube
• d.It has begun to clot already and would leave fibrin strands in the sample

The first drop out of a skin puncture is a mixture of blood and interstitial fluid, and it may pick up residual alcohol from the prep, so it is wiped away and collection begins with the second drop. Discarding it is about dilution and contamination by fluid, not about cell concentration; the first drop is not richer in red cells. Skin flora is a concern when blood cultures are collected, which is a venous procedure and not what a microcollection tube is for. Clotting has not had time to occur in the first seconds, although squeezing the finger hard will cause both hemolysis and tissue-fluid contamination and must be avoided.

Veins of the foot and the ankle may be used for venipuncture only after permission is obtained from the patient's physician. What is the main reason for that restriction?

• a.Puncture there carries a raised risk of thrombosis and of poor healing✓
• b.Foot veins are too narrow to accept any standard multisample needle
• c.Blood from the lower extremities cannot be used for coagulation testing
• d.A tourniquet cannot be positioned correctly anywhere above an ankle vein

The lower extremities are the site most prone to clot formation and to slow, complicated healing, and patients with diabetes, peripheral vascular disease, or heart failure are at real risk of thrombophlebitis or a deep vein thrombosis from a foot puncture. That is why facility policy generally requires physician authorization before the site is used. Equipment is not the barrier: a small-gauge or winged needle fits a foot vein and a tourniquet sits above the ankle without difficulty. Blood drawn from the foot is valid for routine testing, including coagulation studies, so the objection is to harming the patient rather than to spoiling the specimen.

Where should the tourniquet be applied for a venipuncture in the antecubital fossa?

• a.Three to four inches above the intended puncture site✓
• b.Directly over the antecubital crease so the vein bulges below it
• c.One inch above the site so that the vein fills as fast as possible
• d.At the wrist, below the site, to trap blood in the forearm veins

A tourniquet placed three to four inches, roughly 7.5 to 10 cm, proximal to the site slows venous return without cutting off arterial inflow, so the veins below it distend and can be felt. Placed on the crease itself it covers the very skin that must be cleaned and punctured and it sits where the needle and holder need to be. One inch above is close enough to interfere with the equipment and with the angle of insertion. At the wrist it is distal to the antecubital veins and cannot fill them, because a tourniquet only distends the vessels downstream of it.

A patient who takes warfarin has just had blood drawn from the antecubital fossa. How should the technician manage the puncture site?

• a.Bandage the site at once and have the patient raise the arm above the head
• b.Hold firm pressure with the arm held straight until the bleeding has stopped✓
• c.Press for about fifteen seconds and then let the patient hold the gauze
• d.Have the patient bend the elbow over the gauze and hold it there five minutes

A patient on an anticoagulant bleeds for longer, so the technician holds direct pressure over the puncture with the arm extended and inspects the site before any bandage goes on; five minutes or more is ordinary and the dressing is applied only once bleeding has stopped. Bandaging immediately traps continued oozing under the dressing and produces a hematoma that nobody sees until later. Fifteen seconds is too short even for a patient on no medication at all. Bending the elbow over the gauze is a habit many patients bring with them, but it reopens the puncture about as often as it seals it and does not replace direct pressure.

A technician cleanses a venipuncture site with 70 percent isopropyl alcohol. What must happen next, before the needle is inserted?

• a.The site is dried with a sterile gauze pad to take up the excess alcohol
• b.The site is wiped a second time with alcohol, working in a circle outward
• c.The alcohol is left to air-dry completely, with no fanning or blowing on it✓
• d.The site is covered with dry gauze for thirty seconds while the alcohol acts

Alcohol has to evaporate on its own before the skin is punctured. A wet site stings sharply on insertion, and alcohol carried into the tube hemolyzes red cells and distorts results. Fanning the area or blowing on it puts organisms from the air and from the technician's breath straight back onto skin that was just disinfected. Wiping the site with gauze drags resident skin flora back across the cleaned area and undoes the antisepsis. A second alcohol pass or a gauze cover changes nothing about the drying time the technique depends on.

An 82-year-old patient needs a CBC. Her antecubital veins cannot be palpated, and the only accessible vessels are small, fragile veins on the back of the hand. Which equipment is the best choice?

• a.A 21-gauge multisample needle and holder used in the antecubital fossa
• b.A 25-gauge needle on a 10 mL syringe, with the plunger drawn back briskly
• c.A 16-gauge needle and holder, so the tube fills before the vein collapses
• d.A 23-gauge winged collection set with a holder and a small-volume tube✓

A winged, or butterfly, set with a 23-gauge needle and short flexible tubing is made for small, fragile vessels such as the dorsal hand veins, and pairing it with a small-volume tube keeps the vacuum from pulling the vein flat. The 21-gauge multisample needle is the routine choice for an antecubital draw, which makes it tempting here, but this patient has no palpable antecubital vein for it to enter. A 25-gauge needle is narrower than blood collection allows and shears red cells, and yanking a syringe plunger hemolyzes the sample as well. A 16-gauge needle is an infusion size that would tear a hand vein rather than preserve it.

During a multiple-tube venipuncture, at what point must the tourniquet be released?

• a.After the needle is out and the gauze is pressed down
• b.Before the needle is withdrawn from the vein✓
• c.Once the bandage has been placed over the puncture
• d.Just before the needle is inserted into the vein

The tourniquet comes off before the needle does. Usual practice is to release it as soon as blood begins to flow into the first tube, and it must be off in every case before withdrawal, because a needle pulled out of a vein still under tourniquet pressure lets blood escape into the surrounding tissue. Releasing it only after the needle is out, or after the bandage is on, is the exact sequence that produces a hematoma and prolonged bleeding at the site. Releasing it just before insertion collapses the vein that was distended for the stick and the attempt fails.

A technician has attempted a venipuncture on the same patient twice and has not obtained blood either time. What should the technician do next?

• a.Attempt a third stick in the opposite arm with a larger-gauge needle
• b.Ask another technician or the supervisor to make the next attempt✓
• c.Reinsert the used needle at the second site and search for the vein
• d.Document that no specimen could be obtained and cancel the order

Two unsuccessful sticks is the customary limit, after which the patient is handed to a second collector who brings fresh eyes and may find a vein the first person could not. A third attempt by the same technician adds pain and bruising without improving the odds, and a wider needle does nothing to locate a vein that has not been found. Reinserting a needle that has already been in the skin is a contamination and injury hazard and has no place in the technique. Cancelling an ordered test is a decision for the provider who ordered it, not for the person collecting.

As the needle enters the arm the patient cries out and describes a sharp, shooting, electric pain running down the forearm into the hand. What should the technician do?

• a.Withdraw the needle slightly and redirect it toward the median cubital vein
• b.Remove the needle immediately and discontinue the draw✓
• c.Loosen the tourniquet and pause until the pain settles, then continue
• d.Finish the collection quickly using the smallest tube available

Shooting, electric pain that radiates toward the hand is the classic sign of needle contact with a nerve, and the only acceptable response is immediate withdrawal; every extra second of contact adds to the risk of lasting injury. Redirecting the needle drags it across the injured nerve again. Waiting for the pain to settle with the needle still in the arm keeps the source of the injury in place. Finishing quickly with a small tube treats the specimen as more important than the patient. After withdrawal the technician holds pressure, records what the patient described in the patient's own words, and reports the incident.

A requisition asks for a basic metabolic panel on a patient who had a right mastectomy with axillary lymph node removal. Why is the right arm avoided for the draw?

• a.Surgical scarring has hardened the veins in that arm so a needle cannot enter cleanly
• b.Blood from the operated side clots faster and would gel inside a chemistry tube
• c.The operated arm carries weaker arterial pressure, so the tubes fill too slowly to use
• d.Lymph node removal impairs drainage, so the arm risks infection and skewed results✓

Taking out the axillary lymph nodes leaves that arm without normal lymphatic drainage, so it swells easily, clears infection poorly, and the fluid changes in the tissue can alter test values; the restriction lasts indefinitely unless the physician specifically authorizes the limb. Scarring is a genuine reason to avoid one patch of skin, but it is local and it is not what makes an entire post-mastectomy arm off limits. A mastectomy does not change how quickly blood clots or how hard the artery pushes, so the tubes would fill and behave normally. With one arm restricted, the unaffected arm is used.

Midway through a venipuncture the technician sees the area around the needle swelling rapidly and the skin starting to discolor. What should the technician do?

• a.Leave the needle in and ask the supervisor to look at the swelling
• b.Stop the draw and hold firm pressure over the site✓
• c.Continue the draw and ice the arm once the tubes are filled
• d.Advance the needle deeper and fill the remaining tubes

Rapid swelling with discoloration at the needle means a hematoma is forming: blood is leaking into the tissue, and the response belongs to the person already at the bedside. The tourniquet is released, the needle is withdrawn, and firm pressure is held over the site for several minutes. Waiting for someone else to come and look leaves a needle in a leaking vessel while the hematoma grows, and this is a situation the technician is trained to manage without delay. Ice may be offered after bleeding is controlled, but collecting more tubes while the tissue fills with blood is not acceptable, and pushing the needle deeper only enlarges the tear.

Before a routine draw, a patient tells the technician that she has fainted at every blood collection she has ever had. What is the best action?

• a.Seat her upright in the drawing chair and talk her through each step of the draw
• b.Have her sip a cup of juice while the tubes are being collected
• c.Hold an ammonia inhalant open near her face throughout the collection
• d.Position her reclined or lying flat for the draw and observe her afterward✓

A patient with a history of syncope at every draw is positioned reclined or supine before the needle goes in, so that losing consciousness cannot become a fall, and she is watched for several minutes after the collection. Talking an anxious patient through the steps is good practice and worth doing, but it does not protect someone who faints regardless of how calm she feels. Anything to eat or drink during the collection becomes a choking hazard the moment she loses consciousness. Ammonia inhalants are no longer recommended, because they can provoke bronchospasm in a patient with asthma and can cause a sudden head jerk that injures the neck.

A technician is performing a capillary puncture on an adult patient. Which site and lancet orientation are correct?

• a.The very center of the fingertip of the index finger, along the fingerprint lines
• b.The pad of the thumb, angled across the print lines toward the nail bed
• c.Slightly off center on the fleshy pad of the middle finger, across the prints✓
• d.The side of the tip of the fifth finger, running along the print lines

An adult skin puncture is taken from the palmar surface of the last segment of the middle or the ring finger, just off the center of the pad, with the lancet placed across the lines of the fingerprint so the blood beads up rather than running down a groove. The center of the fingertip is the most sensitive point and the bone sits closest to the surface there, and the index finger is more calloused and more sensitive than its neighbors. The thumb is calloused and has a palpable pulse. The fifth finger has too little tissue over the bone, which makes bone injury a real risk.

The small rounded wave that appears just before each QRS complex on an EKG tracing represents which event?

• a.The mechanical contraction of the atria pushing blood forward
• b.The spread of electrical depolarization across both atria✓
• c.The electrical recovery of the ventricles after a beat
• d.The impulse pausing at the AV node before the ventricles

The P wave is produced by electrical depolarization moving across the right and left atria, and the atria squeeze a moment later, so the tracing shows the signal rather than the mechanical event. An EKG records electrical activity only, which is why describing the atria physically pushing blood forward is wrong even though the two events are linked in time. Ventricular recovery produces the T wave, and the delay at the AV node appears as the flat segment after the P wave rather than as the wave itself.

The PR interval on a 12-lead tracing measures the time from:

• a.the start of the P wave to the peak of that same P wave
• b.the end of the QRS complex to the start of the T wave
• c.the beginning of the P wave to the start of the QRS complex✓
• d.the start of one QRS complex to the start of the next

The PR interval runs from the onset of the P wave to the onset of the QRS complex, so it measures how long the impulse takes to travel from the atria through the AV node to the ventricles. Measuring within the P wave alone gives atrial depolarization time, not conduction time down to the ventricles. The stretch from the end of the QRS to the start of the T wave is the ST segment, and the distance from one QRS to the next is the R-R interval, which is used to calculate rate.

EKG paper is running at the standard speed of 25 mm/sec. One small box on that paper represents:

• a.0.20 second, one large box wide
• b.0.10 second, two large boxes
• c.0.02 second, half a small box
• d.0.04 second, or 1 mm wide✓

At 25 mm/sec each small box is 1 mm wide, so 25 mm of paper passes in one second and one small box equals 1 divided by 25, or 0.04 second. Five small boxes make one large box, which is 5 mm wide and represents 0.20 second. A small box measures 0.02 second only when the paper speed has been doubled to 50 mm/sec. A span of 0.10 second is two and a half small boxes, not one.

A monitored rhythm is regular, and the technician counts 4 large boxes between two R waves. Using the 300 method, the rate is about:

• a.60 beats per minute (300 divided by 5)
• b.100 beats per minute (300 divided by 3)
• c.150 beats per minute (300 divided by 2)
• d.75 beats per minute, from 300 over 4✓

The 300 method divides 300 by the number of large boxes between two consecutive R waves, so 300 over 4 gives about 75 beats per minute. Five large boxes would give 60, three would give 100, and two would give 150, so each of those answers counts the wrong number of boxes. The method works because one large box is 0.20 second and 300 large boxes pass in a minute. It applies only to a regular rhythm; an irregular one is counted with the six-second method instead.

A technician checks the standardization mark printed at the beginning of a 12-lead tracing. On a machine set to normal calibration, that mark is:

• a.5 mm tall, marking half a millivolt
• b.10 mm tall, marking one millivolt✓
• c.20 mm tall, marking two millivolts
• d.25 mm tall, matching paper speed

Standard calibration is 10 mm per millivolt, so a correctly set machine prints a mark two large boxes tall at the start of the tracing. Half standardization prints a 5 mm mark and is used when complexes are so tall they overlap, while double standardization prints 20 mm for very small complexes; either change alters the height of everything on the strip and has to be noted. The 25 mm figure belongs to paper speed, which is a horizontal setting and has no effect on the height of the calibration mark.

A technician has placed the V1, V2, and V4 electrodes on a patient's chest. Where does the V3 electrode go?

• a.Midway between the V2 and V4 electrodes, on a line between them✓
• b.In the fifth intercostal space at the left sternal border
• c.Midway between V1 and V2 in the fourth intercostal space
• d.On the left anterior axillary line at the level of V4

V3 sits midway between V2 and V4, which is why those two electrodes are applied first and V3 is positioned only after both landmarks are on the chest. V2 already sits at the left sternal border in the fourth intercostal space, so placing V3 beside the sternum one space lower is far too medial. Putting it between V1 and V2 crowds two electrodes that are only a few centimeters apart across the sternum. The left anterior axillary line at the level of V4 is where V5 belongs, well lateral to the gap V3 has to fill, so an electrode there leaves the anterior wall unrecorded. Misplaced precordial electrodes change what the tracing shows without producing any obvious artifact.

A technician cannot get the chest electrodes to stick to a patient with dense chest hair. Where facility policy permits, the technician should:

• a.Move each chest electrode to the nearest hairless patch of skin
• b.Clip the hair at each site, then apply the electrodes✓
• c.Ask the supervisor whether this tracing can be rescheduled
• d.Tape the electrodes down firmly over the hair

Hair holds the adhesive sensor away from the skin, so clipping a small patch at each site is the accepted fix and it takes only a moment. Moving the sites to hairless skin changes the anatomic landmarks, which changes what each chest lead is looking at, so it is not an acceptable substitute. Taping over hair still leaves an air gap and usually produces a noisy or wandering tracing. Escalating is not called for either, because the obstacle is one the technician can correct at the bedside right now.

A technician is applying the V4 through V6 electrodes to a woman with large breasts. Those electrodes should be placed:

• a.over the top of the breast tissue at the same intercostal spaces
• b.under the breast, on the chest wall at the usual landmarks✓
• c.closer to the sternum, medial to the breast tissue itself
• d.one rib space lower than usual to clear the breast

The accepted practice is to lift or displace the breast and place the electrodes on the chest wall underneath it at the standard landmarks, because tissue between the sensor and the chest wall weakens the recorded signal. Recording over the top of the breast keeps the rib space correct but adds distance and lowers the voltage the machine sees. Shifting the sites toward the sternum or down a rib space moves the electrode off the anatomy it is meant to view and can imitate an abnormal finding. Draping the patient and exposing one site at a time protects privacy while the electrodes go on.

Before starting a 12-lead EKG on an inpatient, the technician confirms identity with two identifiers. Which pair meets that requirement?

• a.The patient's room number and the name on the door
• b.The patient's first name and the room number
• c.The patient's stated name and the assigned bed number
• d.The patient's full name and date of birth✓

Both identifiers must belong to the person rather than to a place, and the standard pair is the full name with the date of birth, checked against the wristband and the order. A room number, a bed number, or a name posted on a door identifies a location, and patients get moved between rooms during a shift. A first name alone is not unique on a unit where two patients may share it. Confirming identity before any electrode is applied keeps the tracing from being filed under the wrong record.

A new technician uses the words electrode and lead as if they mean the same thing. Which statement states the difference correctly?

• a.An electrode is the wire from the machine; a lead is the sticky disc
• b.An electrode is a single tracing on the paper; a lead is the cable
• c.An electrode is the sensor on the skin; a lead is a view between electrodes✓
• d.An electrode measures voltage; a lead is the printed rhythm strip

An electrode is the adhesive sensor stuck to the skin, and a lead is the electrical picture of the heart obtained by comparing the signals from two or more electrodes. That is why a 12-lead EKG needs only 10 electrodes: the machine derives 12 views from those 10 points of contact, so leads and electrodes cannot be counted as the same thing. Calling the cable itself a lead is common on the unit, but the wire is properly a lead wire and is not what the term means on the exam. The paper coming out of the machine is the recording of those views, and one tracing on it is a lead's worth of signal rather than the sensor that produced it.

A patient scheduled for a 12-lead EKG has a below-the-knee amputation of the left leg. Where should the left leg electrode be placed?

• a.On the remaining part of the left limb, with the right leg electrode moved to match✓
• b.On the lower left abdomen, with the other three electrodes left in place
• c.On the left shoulder, just below the left arm electrode site
• d.On the left hip, paired with the electrode on the left arm

The electrode goes on the residual limb, and the electrode on the intact leg is moved to the same level so the two sides stay symmetric and the frontal-plane leads remain comparable. Moving one electrode onto the trunk while the others stay on the limbs makes the sides unequal and shifts the tracing. The shoulder and the hip are not limb-lead positions, and the shoulder site would sit close enough to the arm electrode to distort the recording. Whatever placement is used must be written on the tracing so the provider who reads it knows the electrodes were not in standard positions.

A patient with shortness of breath cannot tolerate lying flat while a 12-lead EKG is recorded. What should the technician do?

• a.Lower the head of the bed to flat for the few seconds needed
• b.Record with the head of the bed up and note the position✓
• c.Seat the patient upright on the edge of the bed with feet down
• d.Wait for the breathing to improve before recording

The tracing may be recorded with the head of the bed elevated when a patient cannot lie flat, and the position is written on the strip so the provider knows the leads were not recorded supine. Forcing the patient flat even briefly worsens the breathing and usually fills the tracing with motion artifact, which defeats the purpose. Sitting on the edge of the bed leaves the arms and legs unsupported and adds muscle noise to the limb leads. Waiting for the breathing to improve delays a test that was very likely ordered because of that breathing.

A technician finds a surgical dressing covering the skin where the V4 electrode belongs. What should the technician do?

• a.Ask the nurse or supervisor how to proceed before recording✓
• b.Take the dressing off, place the electrode, and redress the site
• c.Press the V4 electrode onto the surface of the dressing itself
• d.Move V4 below the dressing and label the strip as usual

A technician does not remove or disturb a surgical dressing, so the nurse responsible for the wound decides whether the site can be uncovered or whether the tracing is taken with a documented adjustment. An electrode pressed onto a dressing has no skin contact and records nothing usable. Shifting the site to another rib space and labeling the strip as a standard tracing hides a change that alters what that lead is looking at. Any departure from the standard landmarks has to be documented on the tracing itself.

A technician has finished a 12-lead EKG and is about to hand the tracing off. What must appear on the tracing first?

• a.The rhythm the technician identified and the name of the physician
• b.The patient's name and ID number, the date, and the time✓
• c.The patient's vital signs and the medications given that morning
• d.The patient's name and the room where it was recorded

A tracing is identified by the patient's name and identification number together with the date and time it was recorded, plus the initials of the person who ran it and a note about any nonstandard placement or changed setting. Writing an interpretation on the strip is outside the technician's role, since reading the tracing belongs to the provider who ordered it. Vital signs and medications are charted elsewhere and do not identify the strip. A room number does not identify the patient, because the patient can be moved before anyone reads it.

A monitored patient's rhythm changes to a wide, regular complex at about 180 beats per minute, and the technician finds the patient unresponsive with no palpable pulse. What should the technician do first?

• a.Silence the monitor alarm and print a rhythm strip for the nurse to review
• b.Report the rhythm to the nurse or the shift supervisor before touching him
• c.Reattach the chest electrodes and watch the tracing for another minute
• d.Call for help, activate the emergency response, and start chest compressions✓

A wide, regular complex near 180 beats per minute in a pulseless patient is ventricular tachycardia without a pulse, one of the lethal rhythms; survival depends on immediate compressions and early defibrillation, so the technician shouts for help, activates the code, and begins CPR. The patient has already been checked, so stepping away to route the finding up the chain of command only delays the response. Silencing the alarm to print a strip and reworking the electrodes both treat the monitor at a moment when the patient needs hands on the chest. Once the team arrives, the technician assists as directed and does not interpret the rhythm or direct treatment.

During continuous monitoring, a technician sees that an alert, comfortable patient has begun having six or more early, wide beats each minute where there had been none an hour ago. What is the appropriate action?

• a.Continue monitoring and mention the change in the end-of-shift handoff report
• b.Widen the alarm limits so the early beats stop setting off the monitor alarm
• c.Obtain a fresh 12-lead tracing to compare with the admission strip
• d.Report the new frequent early beats to the nurse or supervisor promptly✓

Early, wide beats with no P wave in front of them are premature ventricular contractions, and a new increase in their frequency can precede ventricular tachycardia, so the finding goes to the nurse now rather than at the end of the shift. Holding the change for handoff leaves several hours in which the pattern could worsen unseen. Widening the alarm limits hides the very beats the monitor was set to catch. Running a new 12-lead is a procedure done on an order, not something the technician initiates, and it would not replace telling the nurse.

A monitor shows chaotic, irregular waves of constantly changing height with no identifiable P waves, QRS complexes, or T waves. This tracing is most consistent with:

• a.atrial fibrillation conducting at a rapid ventricular rate
• b.coarse artifact from the patient turning himself in bed
• c.asystole showing a few widely spaced complexes
• d.ventricular fibrillation, which is a pulseless emergency rhythm✓

Ventricular fibrillation is chaotic quivering of the ventricles, and the tracing shows disorganized waves of varying size with nothing that can be measured as a complex; the patient has no pulse and needs CPR and defibrillation at once. Atrial fibrillation has a wavy baseline but still produces recognizable QRS complexes, which this tracing lacks. Asystole is a flat or nearly flat line rather than large chaotic waves. Movement artifact is the trap here, and the technician settles it the same way every time, by going to the patient: someone in true ventricular fibrillation is unresponsive within seconds.

A telemetry technician sees a flat line in one lead while the remaining leads show a normal rhythm, and the patient is sitting up talking with a visitor. The most likely cause is:

• a.a broken lead wire or an electrode that has come loose from the skin✓
• b.asystole that is showing in the affected lead before it reaches the others
• c.static from an electrical device running next to the bed
• d.a failing battery in the patient's telemetry transmitter

A flat line confined to a single lead while every other lead traces normally points to a mechanical problem in that channel, so the technician goes to the room, checks the electrode and its wire, and replaces whichever has failed. True asystole is a whole-heart event that flattens all leads at the same moment and leaves the patient unresponsive, which rules it out in a patient who is talking. Static from nearby equipment and a weakening transmitter battery both degrade the entire tracing rather than one lead. The rule the technician works by is to look at the patient before believing the monitor.

A monitored patient's tracing shows repeating sawtooth waves between the QRS complexes, with an atrial rate of about 300 per minute. This pattern is best described as:

• a.atrial flutter, an organized rapid atrial rhythm✓
• b.sinus tachycardia with tall, peaked T waves
• c.atrial fibrillation with an irregular baseline
• d.a paced atrial rhythm with pacing spikes

Repeating sawtooth flutter waves at roughly 250 to 350 per minute, with the ventricles responding at a fraction of that rate, are the signature of atrial flutter. Atrial fibrillation produces a chaotic wavy baseline with no repeating wave shape and an irregularly irregular ventricular response. Sinus tachycardia shows one upright P wave for every QRS rather than several waves between complexes, and tall T waves do not repeat across the baseline. Pacing spikes are thin vertical marks, so a run of them looks nothing like a rolling sawtooth. Because interpreting a rhythm is outside the technician's scope in most facilities, the finding is described and reported to the nurse promptly rather than charted as a diagnosis.

A tracing shows a narrow vertical spike immediately in front of each wide QRS complex, at a regular rate. The technician should recognize this as:

• a.a premature ventricular contraction following each beat
• b.artifact from static electricity building up near the electrodes
• c.a tall, narrow P wave in front of every wide complex
• d.an artificial pacemaker rhythm, seen as regular pacing spikes✓

A pacemaker fires a small electrical impulse that the machine records as a thin vertical spike, and a ventricular paced beat produces a wide QRS immediately after the spike, so a regular spike-then-wide-complex pattern is a paced rhythm. A premature ventricular contraction comes early, has no spike and no P wave, and interrupts the underlying rhythm instead of repeating regularly. Static artifact is random and would not land in the same position before every complex. A P wave is a small rounded deflection, not a hairline spike. What the technician watches for and reports is a spike that is not followed by a complex.

On a monitored strip the rhythm is regular at 72, every P wave is followed by a QRS complex, and the PR interval is a constant 0.28 second. This is most consistent with:

• a.first-degree AV block, reported routinely rather than urgently✓
• b.complete heart block, with the atria and ventricles beating independently
• c.normal sinus rhythm with a PR interval at the long end
• d.a premature atrial contraction after each conducted beat

A PR interval that stays constant and longer than 0.20 second while every P wave still conducts to a QRS defines first-degree AV block; at 0.28 second this tracing is outside the normal range, so calling it normal sinus rhythm is the near miss a candidate has to reject. In complete heart block the P waves and the QRS complexes march at their own separate rates with no fixed relationship, which is not what a constant PR interval shows. A premature atrial contraction is an early beat, and this rhythm is regular. First-degree block is usually asymptomatic, so the technician documents it and reports it in the normal course rather than as an emergency.

A telemetry alarm announces ventricular fibrillation on a patient who was last seen standing at the sink brushing his teeth. What should the technician do first?

• a.Document the alarm and reset the monitor from the central station
• b.Print the strip and compare it with the patient's earlier tracings
• c.Call the emergency response team without leaving the station
• d.Go to the bedside and check the patient at once✓

Brushing teeth produces rapid, jagged motion artifact that can imitate ventricular fibrillation on a single-lead telemetry screen, and the only way to separate artifact from a lethal rhythm is to look at the patient, who in true ventricular fibrillation is unresponsive within seconds. Summoning the emergency team is exactly right the moment the patient is found unresponsive, but summoning it from the station before anyone has laid eyes on him sends a resuscitation team to a man who may be standing at the sink. Printing strips and documenting the alarm treat the monitor instead of the person. From the bedside the technician either calls out for help and starts the facility's response or corrects the artifact, then reports what happened.

A monitor alarms repeatedly during a busy shift on a telemetry unit. Which action is appropriate for the technician?

• a.Turn the alarm volume off until the nurse has time to look at the tracing
• b.Widen the heart rate alarm limits far enough that the alarm stops sounding
• c.Log each alarm and review the pattern at the end of the shift
• d.Check the patient and the electrodes each time the alarm sounds✓

Alarm limits are set according to the order and facility policy, and every alarm is answered by looking at the patient and then at the electrodes and lead wires, with true rhythm changes reported to the nurse. Turning the volume off can leave a lethal rhythm sounding into an empty room. Widening the limits until the noise stops disables the very range the alarm exists to catch, which is the reasoning behind the rule that a technician does not silence or shut off alarms to reduce nuisance. Logging alarms for later review is useful record keeping but does nothing for the patient whose alarm is sounding now.

A patient on continuous telemetry is scheduled for an imaging study, and a transport aide arrives to take him off the unit. Under typical facility policy, what should the technician do?

• a.Switch the transmitter off to save its battery until the patient returns
• b.Notify the nurse before the patient leaves so monitoring coverage is arranged✓
• c.Take the electrodes off and apply a fresh set when the patient comes back
• d.Note the departure in the log and resume watching the bed on his return

Monitoring is ordered by a provider, so a patient does not go off a monitored unit until the nurse knows and coverage during the trip has been arranged; the technician tells the nurse before the aide leaves. Recording the time monitoring stops and restarts is required, but it is documentation of a decision the nurse makes, not a substitute for making the call. Switching off the transmitter or pulling the electrodes ends the ordered monitoring on the technician's own initiative and leaves the screen blank with no one knowing why.

A completed 12-lead tracing contains a stretch of artifact running through two of the leads. What should the technician do with that tracing?

• a.Erase the artifact from the printout before the tracing is filed in the chart
• b.Cut the clean complexes out and tape them onto a fresh strip for the chart
• c.Write a note on the tracing stating that the machine was malfunctioning
• d.Correct the cause of the artifact and record the tracing again✓

A tracing is part of the permanent medical record, so nothing on it is erased, cut apart, redrawn, or explained away; the technician finds the cause, whether that is a loose electrode, dried gel, movement, or a lead wire pulled tight, corrects it, and runs a new tracing labeled with the patient's identifiers, the date, and the time. Erasing and re-taping alter a legal document and destroy the evidence a clinician needs to judge whether the tracing is trustworthy. Writing that the machine malfunctioned records a cause the technician has not established and still leaves an unreadable tracing in the chart.

A technician gets a noisy tracing on a patient who is lying still and relaxed, with the lead wires slack and firmly connected at both ends. What should the technician check next?

• a.Whether the tracing improves when the patient is asked to hold his breath
• b.Whether the electrode gel has dried out or the electrodes have expired✓
• c.Whether the room is cool enough to be making the patient tense his arms
• d.Whether the machine is due for its scheduled maintenance check

Electrode gel dries out once a package has been opened or the expiration date has passed, and a dry electrode makes poor contact with the skin, which shows up as a noisy, unstable tracing; fresh electrodes from a sealed package are the next thing to try after the patient and the cables have been ruled out. A cold, tense patient is a genuine cause of muscle noise, but this patient is described as relaxed and still. Breath holding is used for a baseline that swings with respiration, not for a noisy signal. Machine maintenance matters, but it does not explain a tracing that a new set of electrodes will usually fix.

While a technician applies telemetry electrodes, the patient looks at the monitor and asks whether his heart rhythm is dangerous. What is the best response?

• a.Explain that the nurse or physician will go over the tracing with him✓
• b.Reassure him that the rhythm looks normal and that there is nothing to worry about
• c.Show him the strip and point out the places where the complexes look regular
• d.Tell him not to worry about anything he sees on the screen

Reading a tracing for a patient is interpretation, which belongs to the nurse and the physician, so the technician acknowledges the question, tells the patient who will answer it, and passes it along at once. Saying the rhythm looks normal is an interpretation as well, and a comforting one that turns out to be wrong is worse than no answer. Pointing out regular complexes on the strip is the same interpretation delivered in pictures. Brushing the question aside by telling him not to think about the screen dismisses a real concern and leaves an anxious patient more worried, not less; scope of practice bars the technician from interpreting the tracing, not from listening and relaying the question.

A healthy 19-year-old is monitored with an upright P wave before every QRS, but the R-R interval shortens as she breathes in and lengthens as she breathes out. This rhythm is best described as:

• a.sinus arrhythmia, a normal variant that follows the breathing cycle✓
• b.wandering baseline artifact created by the patient's breathing
• c.frequent premature atrial contractions breaking up the rhythm
• d.sinus bradycardia with occasional dropped beats

Sinus arrhythmia is a sinus rhythm whose rate rises with inspiration and falls with expiration, and it is a common, harmless finding in children and young adults; the P waves stay upright and uniform and each one conducts, which is what this strip shows. A wandering baseline moves the tracing up and down on the paper but leaves the spacing between beats alone, so it cannot explain a changing R-R interval. Premature atrial contractions are early beats with an odd-looking P wave rather than a smooth cyclic speeding and slowing. Sinus bradycardia runs slow and steady and does not drop beats.
