NHA Medical Assistant (CCMA) — All Questions

Which description matches purulent wound drainage?

• a.Thin and clear or straw coloured, which is the drainage expected from a clean healing wound
• b.Thick and opaque, often yellow, green or brown, which suggests infection✓
• c.Bright red and free flowing, which indicates fresh bleeding from a vessel in the wound bed
• d.Pale pink and watery, which is a mixture of clear fluid and a small amount of blood

Purulent drainage is thick, opaque and coloured, and it is the appearance that prompts a report to the provider along with any spreading redness, warmth, swelling, odour or fever. Serous drainage is thin and clear, sanguineous is bright red and serosanguineous is the pale pink mixture of the two.

A provider orders a cold pack for an ankle injured an hour ago. What effect is intended?

• a.Vasoconstriction, which limits the swelling and bleeding into the tissue✓
• b.Vasodilation, which brings extra blood to the area to speed the healing process
• c.Softening of the tissue, which makes the joint easier to move during the examination
• d.A rise in local metabolism, which clears the products of injury out of the joint faster

Cold narrows the vessels, which reduces bleeding, swelling and pain in the first day or so after an injury, and it also slows local metabolism rather than raising it. Heat produces the vasodilation that increases blood flow and is used later for stiffness and chronic pain. A barrier is placed between the pack and the skin and the time is limited.

A patient is asked to collect a first morning urine specimen. Why is that specimen preferred for some tests?

• a.Because urine formed overnight contains no bacteria at all and needs no clean-catch technique
• b.Because the bladder is emptied during sleep, so the morning sample is the freshest available
• c.Because morning urine is warmer, which keeps any cells in it intact until it reaches the laboratory
• d.Because it is the most concentrated of the day, so small quantities are easier to detect✓

Urine that has been in the bladder overnight is the most concentrated of the day, which makes it the best specimen for detecting small amounts of protein, cells, casts or the hormone in a pregnancy test. It is not sterile, so a clean-catch technique still applies when culture or a clean sample is needed.

An adult in the waiting room clutches the throat, cannot speak and is not moving any air. What should the medical assistant do?

• a.Wait and watch
• b.Give abdominal thrusts until the object comes out or the patient becomes unresponsive✓
• c.Reach a finger into the mouth and sweep blindly to hook the object out of the airway and remove it
• d.Give the patient a glass of water so the object can be washed down into the stomach

A complete obstruction in a conscious adult is treated with abdominal thrusts, delivered until the object is expelled or the patient collapses, at which point cardiopulmonary resuscitation is started and emergency services are already on the way. A blind finger sweep can push the object deeper, water cannot pass an obstructed airway, and waiting costs the minutes that matter.

Which technique is used for a choking infant under one year of age?

• a.Standing abdominal thrusts, exactly as they would be delivered to a choking adult patient instead
• b.Chest compressions at the rate used for cardiopulmonary resuscitation of an infant
• c.Five back blows followed by five chest thrusts, repeated while the infant is responsive✓
• d.Holding the infant upside down by the ankles and shaking until the object falls out

An infant is supported face down along the forearm for five back blows between the shoulder blades, then turned face up for five chest thrusts over the lower sternum, and the cycle repeats while the infant is responsive. Abdominal thrusts are avoided in infants because of the risk of organ injury, and shaking an infant by the ankles causes serious harm.

What compression rate is used for adult cardiopulmonary resuscitation?

• a.Around sixty compressions per minute, matching the resting heart rate of an adult
• b.As fast as the rescuer can physically manage, since more compressions move more blood
• c.Around forty compressions per minute, which allows the chest to refill completely
• d.One hundred to one hundred and twenty compressions per minute✓

The rate is one hundred to one hundred and twenty per minute, with a depth of at least two inches in an adult and full recoil of the chest between compressions. Slower rates do not generate enough flow, and pushing faster than the upper limit shortens the filling time so each compression moves less blood. Certification training is required to perform it.

An automated external defibrillator says to stand clear before it analyses the rhythm. Why does that matter?

• a.Contact with the patient can distort the analysis and puts the rescuer at risk of the shock✓
• b.The device needs complete quiet in order to hear the patient's breathing during the analysis phase
• c.Any movement resets the machine, so the pads have to be repositioned from the beginning
• d.The instruction is a formality that most rescuers ignore without any consequence at all

The device reads the electrical rhythm through the pads, and anyone touching the patient adds signal that can lead to a wrong decision, so everyone stands clear during analysis and again before the shock is delivered. It is not a formality; a rescuer in contact when the shock is given receives part of it. The device does not listen for breathing.

A patient becomes pale, cool, clammy and confused with a rapid weak pulse. What should the medical assistant do while help is coming?

• a.Sit the patient upright
• b.Lay the patient flat, keep them warm, and elevate the legs unless injury makes that unsafe✓
• c.Give the patient a large drink of water to replace the fluid that has been lost
• d.Walk the patient slowly around the room so that the circulation is encouraged to recover on its own

Those signs describe shock, and lying flat with the legs raised helps blood reach the brain while a blanket limits further heat loss. Leg elevation is avoided with a suspected head, spine or leg injury or when it worsens breathing. Nothing is given by mouth to a patient who may deteriorate, and walking a patient in shock risks a collapse.

A patient has a generalised seizure in the office. What should the medical assistant do during it?

• a.Place a padded object between the teeth to stop the patient biting the tongue
• b.Hold the arms and legs still so that no furniture nearby can be struck
• c.Move furniture away, protect the head, note the time, and do not restrain the patient✓
• d.Splash cold water on the face to shorten the seizure and bring the patient round faster

Care during a seizure is protective rather than corrective: clear the space, cushion the head, loosen anything tight at the neck, time the event and stay until it ends, then turn the patient onto the side. Restraint causes injury, nothing is placed in the mouth, and cold water does nothing except add to the confusion afterwards.

A patient has a nosebleed in the waiting area. What is the correct first aid?

• a.Tilt the head back so the blood runs backward and the bleeding stops more quickly
• b.Pack the nostril tightly with gauze and leave the packing in place until the next clinic visit
• c.Lie the patient flat with a cold pack on the forehead until the bleeding has stopped
• d.Sit the patient upright leaning forward and pinch the soft part of the nose for ten minutes✓

Sitting up and leaning forward keeps blood out of the throat, and steady pressure on the soft part of the nose, held without peeking for about ten to fifteen minutes, lets a clot form. Tilting the head back sends blood into the stomach and can cause vomiting or choking, lying flat does the same, and packing is a clinician's procedure.

A patient spills a cleaning chemical into one eye. What is the immediate action?

• a.Irrigate the eye with water or saline from the inner corner outward for a prolonged period✓
• b.Cover the eye with a dry sterile pad and send the patient straight to the emergency department
• c.Apply a soothing ophthalmic ointment from the treatment room stock to relieve the burning
• d.Ask the patient to blink rapidly for several minutes so that tears wash the chemical away

Prolonged irrigation, usually at least fifteen to twenty minutes, is what limits the injury, and the flow runs from the inner corner outward so the chemical is not carried into the other eye. The provider is alerted and the product name and the safety data sheet are found while irrigation continues. Covering, ointment and blinking all leave the chemical in place.

A patient with diabetes is shaky, sweating and confused, and can still swallow safely. What is the usual first response?

• a.Give a large protein snack
• b.Have the patient lie down in a dark room until the symptoms settle on their own, without giving anything
• c.Give a long-acting insulin dose from the clinic stock to bring the reading back to normal
• d.Give about fifteen grams of a fast-acting carbohydrate and recheck the glucose in fifteen minutes✓

Those symptoms suggest a low blood glucose, and the usual approach for a conscious patient who can swallow is about fifteen grams of fast-acting carbohydrate, such as glucose tablets or juice, followed by a repeat measurement about fifteen minutes later. Protein acts too slowly, insulin would drive the glucose lower still, and doing nothing lets it fall further.

A caller describes sudden facial drooping, one weak arm and slurred speech that began twenty minutes ago. What does this pattern suggest?

• a.A migraine that should be managed at home with the patient's usual medication and rest
• b.A panic attack that will settle if the caller is coached through slow breathing on the phone
• c.A possible stroke, which needs emergency services now because treatment is time limited✓
• d.A pinched nerve in the neck that can wait for the next available appointment in the clinic

Face, arm and speech changes of sudden onset are the recognised warning signs of stroke, and the time the symptoms began is the fact that decides which treatments remain possible, so the call becomes an emergency call rather than an appointment. Nothing about this pattern fits a migraine, a panic attack or a pinched nerve.

How should a small thermal burn be cooled as first aid?

• a.With ice held directly against the skin until the pain has completely disappeared
• b.With butter or an oil-based ointment, which seals the surface and keeps out the air
• c.With cool running water for a sustained period, then a clean non-adherent dressing✓
• d.With a dry dressing only, since any moisture on a burn increases the risk of infection

Cool running water for a sustained period, commonly quoted as ten to twenty minutes, removes heat from the tissue and limits how deep the injury becomes. Ice causes further tissue damage, and butter or ointment traps heat and has to be removed before the burn can be assessed. Jewellery is taken off early, before swelling begins.

A patient arrives with a deformed forearm after a fall. What should the medical assistant do while waiting for the provider?

• a.Support the arm in the position found, apply cold, and avoid straightening the limb✓
• b.Straighten the arm gently so that the bones return toward their normal alignment
• c.Apply a warm pack to the deformity so the muscles relax before the examination
• d.Ask the patient to move the wrist and fingers repeatedly to check that nothing is broken

A suspected fracture is immobilised as it lies, supported with padding or a sling, with cold applied over a barrier to limit swelling, and the fingers checked for colour, warmth and sensation. Attempting to straighten a deformity can damage vessels and nerves, heat increases swelling, and repeated movement is painful and diagnoses nothing.

How should a patient be instructed to produce a sputum specimen?

• a.Spit saliva into the container
• b.Rinse the mouth with water, then cough deeply from the chest into the sterile container✓
• c.Gargle with an antiseptic mouthwash first so that the specimen is not contaminated by mouth flora
• d.Collect whatever accumulates in the container over the course of the whole following day

Sputum comes from the lower airway, so the patient rinses with plain water to reduce mouth flora, takes several deep breaths and coughs from deep in the chest, usually first thing in the morning. Saliva is rejected. Antiseptic mouthwash can kill the organism being looked for, and an all-day collection at room temperature overgrows.

A wound culture is ordered from an open leg ulcer. Which technique gives the most useful specimen?

• a.Swab the dry skin surrounding the ulcer, where the organism spreads outward from the wound
• b.Swab the crust on the surface, since that is where the infecting organism concentrates
• c.Clean the surrounding skin, then swab the base of the wound without touching the edges✓
• d.Squeeze the ulcer until fluid appears on the skin and collect that fluid on the swab tip

A culture is meant to identify what is growing in the wound, so the swab samples the wound bed after the surrounding skin has been cleaned, avoiding contact with intact skin and crust that carry ordinary flora. Sampling the skin, the crust or fluid squeezed onto the skin returns colonisers and can send the patient home on the wrong antibiotic.

A patient is given a home stool test kit. What should the medical assistant say about diet restrictions?

• a.No test of this kind has any dietary restriction, so the patient may eat normally throughout
• b.Every stool test requires three days without any meat, fruit or vegetable of any kind
• c.The patient should fast completely for twelve hours before each of the three samples
• d.Follow the instructions for that specific kit, since guaiac and immunochemical tests differ✓

Older guaiac based tests commonly ask the patient to avoid red meat, some raw vegetables, vitamin C supplements and certain medications for a few days, while the fecal immunochemical tests in wide use generally need no dietary restriction. Because the requirement depends on the kit, the instructions supplied with it govern, and a blanket rule is wrong either way.

A urine specimen is needed from an infant who is not toilet trained. What is the usual method?

• a.Clean the area and apply a paediatric adhesive collection bag, then check it frequently✓
• b.Wring out the wet diaper into a specimen container once the infant has passed urine
• c.Wait for the infant to void into a clean nappy and send the nappy itself to the laboratory
• d.Ask the parent to hold a cup in position for as long as it takes the infant to pass urine

The perineum is cleaned and dried, an adhesive bag is applied over the urethral opening, and the infant is checked every fifteen minutes or so because a bag left in place too long is uncomfortable and easily contaminated. Diaper material absorbs urine and adds fibres and gel, and neither a wrung out diaper nor a nappy is an acceptable specimen.

What does the teach-back method ask a patient to do at the end of an instruction?

• a.Sign a form confirming it
• b.Explain the instruction back in their own words so gaps can be found and corrected✓
• c.Repeat the instruction word for word so the assistant knows they were listening closely
• d.Take home a printed handout and read it before the next scheduled appointment date

Teach-back tests the explanation rather than the patient: asking someone to say it back in their own words reveals what did not land, and the assistant then re-explains that part and checks again. A signature and a handout record that information was given, and word for word repetition can be done without any understanding at all.

Which instruction sheet is most likely to be understood by a patient with limited health literacy?

• a.One that uses the correct clinical terms throughout, since precision prevents misunderstanding
• b.One that packs the information into dense paragraphs so nothing has to be left out of it
• c.One in plain everyday language with short sentences and the key action stated first✓
• d.One that lists every possible side effect first so the patient can weigh the risks properly

Plain words, short sentences, one idea at a time and the action the patient must take stated up front are what carry across a range of reading abilities, and pictures help. Clinical vocabulary, dense text and a list of every rare side effect ahead of the instruction all obscure what the patient actually has to do.

A patient is taught the three-point crutch gait. Which pattern is correct?

• a.Both crutches and both legs move forward together in a single co-ordinated movement
• b.The right crutch moves with the right leg, then the left crutch with the left leg in turn
• c.The crutches are carried under one arm while the patient hops on the unaffected leg
• d.Both crutches and the affected leg move forward, then the unaffected leg swings through✓

The three-point gait keeps weight off one limb: both crutches and the affected leg advance together as one point, then the stronger leg comes through. The crutch handgrips take the weight rather than the armpits, which is checked before the patient leaves. Moving a crutch with the leg on the same side is a two-point pattern, and hopping is unsafe.

A patient is placed in an arm sling after a shoulder injury. How should the sling sit?

• a.Supporting the forearm with the hand slightly above the elbow and the knot off the spine✓
• b.Holding the arm completely straight down at the side so the shoulder joint is stretched out fully
• c.With the hand hanging lower than the elbow, which lets gravity reduce the swelling
• d.Tied tightly across the front of the throat so the weight is carried by both shoulders

A sling supports the forearm with the hand a little higher than the elbow, which limits swelling in the hand, and the knot is placed to the side of the neck rather than over the spine where it presses. Letting the hand hang low causes swelling, a straight arm gives no support, and a knot across the throat is dangerous.

A patient with a new low-sodium diet asks which change will help most. What is the most useful advice?

• a.Stop adding salt at the table
• b.Read labels on packaged and restaurant foods, which carry most of the sodium people eat✓
• c.Replace all cooking salt with sea salt, which contains far less sodium than table salt does
• d.Drink much more water each day so that the extra sodium is flushed out by the kidneys

Most dietary sodium comes from processed, packaged and restaurant food rather than the salt shaker, so learning to read labels changes more than table habits do. Sea salt is chemically sodium chloride like any other salt. Extra water does not remove a sodium load, and specific dietary counselling belongs to the provider or a dietitian.

Why is passive range of motion performed on a patient who cannot move a limb?

• a.To build muscle strength in the limb so the patient can begin walking again more quickly
• b.To warm the joint before an examination so the provider can assess it more comfortably
• c.To keep the joint mobile and limit the contractures that follow prolonged immobility✓
• d.To measure how much pain the patient can tolerate before the next dose is given

Moving a joint through its range when the patient cannot do it maintains flexibility and slows the shortening of muscles and tendons that turns into a fixed contracture. It is done gently, within a comfortable range, and stopped if it causes pain. Passive movement does not build strength, which requires the patient's own muscle effort.

A patient with severe bleeding from a forearm laceration arrives at the front desk. What is the first action?

• a.Apply a tourniquet above the elbow before anything else is attempted on the wound
• b.Wash the wound thoroughly under running water to see how deep the laceration goes
• c.Apply an antiseptic and a small adhesive dressing while the provider is being located
• d.Apply firm direct pressure with gloved hands and a clean dressing, and call for help✓

Direct pressure over the wound with a dressing, held firmly and continuously with gloves on, controls most external bleeding, and more dressings are added on top rather than lifting the first to look. A tourniquet is reserved for bleeding that direct pressure cannot control, and washing or dressing a heavily bleeding wound delays the one thing that works.

A patient calls having swallowed an unknown quantity of a household cleaner. What should the medical assistant do?

• a.Get the product name and the time, and connect the caller to poison control or emergency services✓
• b.Tell the caller to induce vomiting at once so the chemical leaves the stomach quickly
• c.Advise a large glass of milk, which neutralises any household chemical in the stomach
• d.Book the earliest available appointment and ask the caller to bring the product container along with them

The product, the amount and the time are the facts an expert needs, and the call goes straight to poison control or emergency services rather than into an appointment book. Inducing vomiting is no longer advised and causes further injury with a corrosive, and no household drink reliably neutralises an unknown chemical.

Which observation about a patient's ability to manage at home belongs in the record?

• a.The assistant's impression that the patient's home is probably untidy and poorly organised
• b.That the patient reports being unable to climb the stairs to the bathroom without resting✓
• c.A conclusion that the patient can no longer live alone and needs residential care arranged
• d.A judgement that the family is not doing enough to help the patient at home each day

What the patient reports and what the assistant directly observes belong in the record, in the patient's words where possible, because they are facts another clinician can act on. Impressions about a home nobody has seen, judgements about a family and conclusions about where someone should live are neither observations nor the assistant's to make.

A patient is booked for a hearing screening with an audiometer. What should the medical assistant do before the test?

• a.Explain the signal the patient must give and test in a quiet room away from equipment noise✓
• b.Ask the patient to remove all clothing above the waist and put on an examination gown
• c.Irrigate both ear canals with warm water so no wax can interfere with the tones being heard
• d.Tell the patient to answer only for the louder tones so the results are not confused by guessing

The patient needs to know how to signal that a tone was heard, and the room has to be quiet enough that ambient noise does not mask the quietest tones being tested. Irrigation is a separate ordered procedure and is not a routine preparation. Instructing a patient to ignore quiet tones would defeat the purpose of measuring the threshold.

A patient's chart lists an allergy to shellfish and the assistant is preparing the room for a minor procedure. What is the relevant action?

• a.No action, since shellfish allergy has no bearing on anything used in a treatment room
• b.Substitute an antiseptic of the assistant's own choosing without telling the provider
• c.Flag the allergy to the provider, who decides which antiseptic and materials are used✓
• d.Ask the patient whether the reaction was severe enough to justify changing the plan

An allergy noted in the record is brought to the provider's attention so that products and materials can be chosen with it in mind, and the allergy is verified with the patient at the visit. Choosing a substitute unilaterally is outside the role, doing nothing ignores a documented allergy, and asking a patient to judge whether their own allergy counts is not an assessment.

Which patient should be brought back to a room ahead of the others waiting?

• a.A patient who arrived first and has been waiting patiently in the reception area since then
• b.A patient with chest pain and shortness of breath who has just walked through the door✓
• c.A patient who has a long appointment booked and will otherwise run past the lunch break
• d.A patient who is a long-standing member of the practice and knows the staff well by name

Triage orders patients by clinical urgency rather than by arrival time, appointment length or familiarity, and chest pain with breathlessness is the presentation that cannot wait. The provider is told immediately. Arrival order governs when nobody in the room is urgent, which is most of the time but not this time.

A patient who uses a wheelchair arrives for an examination that requires the table. What is the correct approach?

• a.Perform the whole examination in the wheelchair, since transferring a patient is always unsafe
• b.Ask the patient's companion to lift the patient onto the table without any equipment
• c.Reschedule the visit for a clinic that has different examination furniture available
• d.Ask the patient how they transfer, use the height-adjustable table or a lift, and get help✓

The patient usually knows the safest way to move, so the transfer starts with asking, then uses a low or height-adjustable table, a transfer board or a lift, with enough staff to do it safely. Examining in the chair is a fallback when a proper transfer is not possible, an untrained companion lifting is how people are dropped, and rescheduling denies care.

Which finding on a routine visit should be reported to the provider before the patient leaves?

• a.A patient who mentions that a family member has recently started the same medication
• b.A blood pressure of 190/115 mmHg recorded on two readings a few minutes apart✓
• c.A patient who says the waiting room was colder than usual on this particular visit
• d.A weight that is two pounds higher than the weight recorded at the last routine visit

A reading in that range is a hypertensive crisis and is reported at once rather than filed for the provider to notice later, because the patient may need immediate assessment. A two pound weight change, a comment about the room and a relative's prescription are all recorded where relevant but none of them needs an interruption.

How should a medical assistant document that a patient declined a recommended screening test?

• a.Record the assistant's opinion about why the patient is unlikely to have needed the test
• b.Leave the record blank so the recommendation can be made again at the next appointment
• c.Record that the test was recommended, that the patient declined, and who was informed✓
• d.Record only that the test was recommended, since a decision belongs to the patient alone

The record shows that the recommendation was made, that the patient declined and who was told, which is what protects both the patient and the practice if the question is asked later. Leaving it blank makes it look as though the subject never came up, recording only the recommendation is half the event, and the assistant's opinion is not documentation.
