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.

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.
