Question 1Certification content area (not enumerated in source)

A client asks the nurse aide to help them walk to the bathroom. Which action should the nurse aide take first?

  1. Ask another aide to walk behind the client
  2. Place the client's shoes on and begin walking
  3. Check the care plan and the client's mobility status Correct answer.
  4. Grab the gait belt and pull the client upright

Explanation

Before any transfer or ambulation, the aide must review the care plan and confirm the client's current mobility orders and any weight-bearing limits. Acting before checking this information risks injury to both the client and the aide.

Question 2Certification content area (not enumerated in source)

Which finding should the nurse aide report to the nurse immediately?

  1. A client reports sudden shortness of breath Correct answer.
  2. A client's hair is uncombed after sleeping
  3. A client prefers to eat lunch alone
  4. A client's toenails are slightly long

Explanation

Sudden shortness of breath can signal a serious change such as a clot, heart problem, or respiratory decline and must be reported at once. Routine grooming and social preferences are not urgent findings.

Question 3Certification content area (not enumerated in source)

The nurse aide is measuring a client's blood pressure. How should the cuff be positioned?

  1. At the level of the heart with the arm supported Correct answer.
  2. Above the shoulder with the arm raised overhead
  3. Over the elbow joint with the arm hanging down
  4. Over the sleeve of a thick sweater

Explanation

The cuff should sit on the bare upper arm at heart level, with the arm supported and relaxed, so the reading reflects true arterial pressure. Poor positioning produces inaccurate values that can mislead the care team.

Question 4Certification content area (not enumerated in source)

A client is on aspiration precautions. Which action best reduces the risk of choking during meals?

  1. Having the client sit upright and eat slowly Correct answer.
  2. Encouraging the client to talk while eating
  3. Offering thin liquids with a straw
  4. Leaving the client alone to eat quickly

Explanation

An upright position and a slow, unhurried pace reduce the chance that food or liquid enters the airway. Supervision and proper positioning are core parts of aspiration precautions.

Question 5Certification content area (not enumerated in source)

Which statement describes proper hand hygiene for the nurse aide?

  1. Wash with soap and water when hands are visibly soiled Correct answer.
  2. Wear gloves instead of washing hands between tasks
  3. Use alcohol rub after contact with visible blood
  4. Rinse hands with water only between clients

Explanation

Soap and water are required when hands are visibly dirty or contaminated with body fluids, because alcohol rub does not remove visible material. Gloves never replace hand hygiene.

Question 6Certification content area (not enumerated in source)

A client who uses a wheelchair must be left in the chair for a while. What should the nurse aide do?

  1. Leave the wheels unlocked for easy movement
  2. Lock the wheels and place the chair near a wall Correct answer.
  3. Remove the footrests while the client sits
  4. Tip the chair back against a table

Explanation

Locking the wheels and positioning the chair against a stable surface prevents rolling or tipping when the client is unattended. Unlocked wheels are a common cause of falls.

Question 7Certification content area (not enumerated in source)

The nurse aide notices a small fire in a trash can. Which action should be taken first?

  1. Wait to see whether the fire goes out
  2. Throw water on the flames
  3. Open a window to clear the smoke
  4. Rescue anyone in danger and sound the alarm Correct answer.

Explanation

Fire response begins with protecting people: remove anyone in danger, activate the alarm, and contain the fire if trained. Water and open windows can worsen certain fires or spread smoke.

Question 8Certification content area (not enumerated in source)

A client is confused and keeps trying to get out of bed. Which approach is most appropriate?

  1. Ask another client to watch the confused client
  2. Place the bed low with the call light within reach Correct answer.
  3. Apply a vest restraint without an order
  4. Raise the bed and leave the side rails down

Explanation

A low bed, a call light in reach, and frequent checks reduce fall risk without restricting the client. Restraints require a specific order and are used only as a last resort.

Question 9Certification content area (not enumerated in source)

When providing a bed bath, which action protects the client's privacy and dignity?

  1. Wash the entire body at once with the covers off
  2. Leave the door open for ventilation
  3. Expose only the body part being washed and cover the rest Correct answer.
  4. Discuss the client's care with visitors in the room

Explanation

Keeping the client covered except for the area being washed preserves privacy, warmth, and dignity. This technique is standard practice during bathing and personal care.

Question 10Certification content area (not enumerated in source)

The nurse aide is asked to obtain a stool specimen. Which action is correct?

  1. Collect the specimen from the toilet bowl water
  2. Mix the specimen with urine to increase the sample
  3. Place the specimen in a clean container and label it Correct answer.
  4. Store the specimen at room temperature for a day

Explanation

Stool specimens are collected in a clean container, labeled with client information, and sent promptly per policy. Contamination with toilet water or urine invalidates the sample.

Question 11Certification content area (not enumerated in source)

A client with an indwelling urinary catheter has a drainage bag. Where should the bag be kept?

  1. Hanging above the level of the bladder
  2. Below the level of the bladder, off the floor Correct answer.
  3. Resting on the floor beside the bed
  4. Pinned to the client's clothing at waist height

Explanation

Gravity drainage requires the bag to stay below the bladder, and keeping it off the floor prevents contamination. Raising the bag allows urine to flow back and cause infection.

Question 12Certification content area (not enumerated in source)

A client refuses a prescribed medication. What should the nurse aide do?

  1. Discard the medication and say nothing
  2. Report the refusal to the nurse and document it Correct answer.
  3. Hide the medication in the client's food
  4. Persuade the client by threatening consequences

Explanation

Clients have the right to refuse treatment, and the aide must report the refusal and document it accurately. Concealing medication or coercing the client violates rights and safety.

Question 13Certification content area (not enumerated in source)

Which action best protects a client's confidentiality?

  1. Sharing updates with the client's neighbors
  2. Posting care details on social media
  3. Leaving the medical record open in the hallway
  4. Discussing the client only with the care team Correct answer.

Explanation

Health information may be shared only with those who need it for care. Discussing residents outside the care team or leaving records exposed breaches confidentiality.

Question 14Certification content area (not enumerated in source)

A client has a stage 2 pressure injury on the heel. Which action supports healing?

  1. Massage the reddened area firmly
  2. Keep the heel off the mattress with a positioning device Correct answer.
  3. Rub the area with alcohol each shift
  4. Apply tight bandages around the heel

Explanation

Relieving pressure from the injured area allows blood flow and healing; positioning devices float the heel off the surface. Massage, alcohol, and tight wraps further damage fragile tissue.

Question 15Certification content area (not enumerated in source)

The nurse aide is feeding a client who has had a stroke. Which sign may indicate swallowing difficulty?

  1. The client chews slowly and swallows well
  2. The client coughs or has a wet voice after swallowing Correct answer.
  3. The client asks for more water
  4. The client finishes the meal in twenty minutes

Explanation

Coughing, choking, or a gurgly voice after swallowing suggests food or liquid is entering the airway. The aide should stop feeding and report the finding to the nurse.

Question 16Certification content area (not enumerated in source)

A client reports pain rated 7 out of 10. What should the nurse aide do?

  1. Wait until the next scheduled medication round
  2. Report the pain to the nurse and note it in the record Correct answer.
  3. Tell the client the pain will pass and continue care
  4. Give the client an over-the-counter pain pill

Explanation

Pain is reported to the nurse so it can be assessed and treated, and the aide documents what the client described. Aides do not decide on or administer medication.

Question 17Certification content area (not enumerated in source)

Which technique is correct when moving a client up in bed?

  1. Bend at the waist and pull with the arms
  2. Twist the torso while lifting
  3. Hold the client under the arms and drag
  4. Keep the feet wide, bend the knees, and use the legs Correct answer.

Explanation

Good body mechanics means a wide base, bent knees, and lifting with the legs close to the body. Bending at the waist, twisting, or dragging a client strains the aide and can injure the client.

Question 18Certification content area (not enumerated in source)

A client is receiving oxygen through a nasal cannula. Which safety rule applies?

  1. Increase the oxygen flow without an order
  2. Post no-smoking signs and keep flames away Correct answer.
  3. Keep the cannula tubing kinked to save oxygen
  4. Apply petroleum jelly to the nostrils

Explanation

Oxygen supports combustion, so open flames and smoking must be kept away from the client and equipment. Only the prescribed flow rate is used.

Question 19Certification content area (not enumerated in source)

A client becomes angry and raises a fist at the nurse aide. What is the best first response?

  1. Raise your voice to show authority
  2. Turn your back and continue the task
  3. Grab the client's arm to restrain it
  4. Step back, keep a safe distance, and call for help Correct answer.

Explanation

Creating distance protects the aide and gives the client space to calm down; help should be summoned according to facility policy. Escalating the conflict or turning away increases danger.

Question 20Certification content area (not enumerated in source)

Which observation suggests a client may be dehydrated?

  1. Moist mucous membranes and pale urine
  2. Warm skin and a steady appetite
  3. Clear urine and regular thirst
  4. Dark concentrated urine and dry mouth Correct answer.

Explanation

Dark, concentrated urine and a dry mouth are common signs of inadequate fluid intake and should be reported. Clear urine and moist tissues suggest adequate hydration.

Question 21Certification content area (not enumerated in source)

A client has an order for a clear liquid diet. Which item is appropriate?

  1. Clear broth and gelatin Correct answer.
  2. Cream of tomato soup
  3. Oatmeal with milk
  4. Vanilla milkshake

Explanation

A clear liquid diet includes items that are transparent at room temperature, such as broth, gelatin, and clear juice. Milk products, cream soups, and cereals are not allowed.

Question 22Certification content area (not enumerated in source)

A client's daughter demands to see the medical record. What should the nurse aide do?

  1. Refer the request to the nurse or privacy officer Correct answer.
  2. Refuse and argue with the daughter about the law
  3. Show the record because family members have full access
  4. Read the record aloud but keep the chart closed

Explanation

Access to health information follows privacy rules and client authorization, so the request is routed to the nurse or privacy officer. The aide should not release or discuss records independently.

Question 23Certification content area (not enumerated in source)

The nurse aide finds a client on the floor after a fall. Which action comes first?

  1. Move the client back into bed alone
  2. Ask the client to walk to a chair to test strength
  3. Help the client stand up quickly
  4. Check responsiveness and stay with the client while calling for help Correct answer.

Explanation

After a fall, the aide stays with the client, checks responsiveness, and calls for help so the nurse can assess for injury before any movement. Moving a client who may have fractures or head injury can cause harm.

Question 24Certification content area (not enumerated in source)

Two clients call for help at the same time. One is short of breath and the other needs a blanket. How should the nurse aide prioritize?

  1. Deliver the blanket first because it is quick
  2. Ask both clients to wait until rounds
  3. Delegate both tasks to a housekeeping worker
  4. Respond to the client with breathing difficulty first Correct answer.

Explanation

Care is prioritized by urgency, and breathing difficulty can indicate a life-threatening change, so that client is seen first. Comfort requests are addressed after immediate needs are met.

Question 25Certification content area (not enumerated in source)

A client with dementia repeatedly asks where a deceased spouse is. Which response best supports the client?

  1. Correct the client firmly and explain the spouse has died
  2. Ignore the question until the client forgets it
  3. Tell the client to stop asking the same question
  4. Redirect gently to a comforting activity and acknowledge feelings Correct answer.

Explanation

For a client with dementia, acknowledging the emotion and gently redirecting reduces distress without repeated confrontation about the loss. Firm correction can cause fresh grief and agitation each time.

Question 26Certification content area (not enumerated in source)

A nurse aide is preparing to wash their hands with soap and water. Which step should be performed first?

  1. Wet the hands with warm running water Correct answer.
  2. Turn off the faucet using a dry paper towel
  3. Dry the hands with a clean paper towel
  4. Apply soap and scrub for at least 20 seconds

Explanation

Handwashing begins by wetting the hands with warm running water before soap is applied. Soap works best when the hands are already wet, and warm water is more comfortable and effective than cold. Drying and turning off the faucet come at the end of the procedure.

Question 27Certification content area (not enumerated in source)

A nurse aide is counting a client's radial pulse. Where should the aide place the fingers?

  1. On the side of the neck beside the windpipe
  2. In the groove behind the knee
  3. On the thumb side of the wrist, below the crease Correct answer.
  4. At the inner bend of the elbow

Explanation

The radial pulse is felt on the thumb side of the wrist, just below the wrist crease, using two or three fingertips. The thumb should not be used because it has its own pulse and may confuse the count. Pressure should be light until the beat is felt clearly.

Question 28Certification content area (not enumerated in source)

A client is on bed rest and cannot turn independently. How often should the nurse aide reposition this client?

  1. Once each shift
  2. Every eight hours
  3. At least every two hours Correct answer.
  4. Only when the client asks

Explanation

Clients who cannot move themselves should be repositioned at least every two hours to relieve pressure on bony areas. Regular turning supports circulation and helps prevent pressure injuries. Waiting longer or relying on the client's request allows prolonged pressure on the skin.

Question 29Certification content area (not enumerated in source)

A nurse aide is measuring a client's blood pressure. Which action supports an accurate reading?

  1. Let the client talk during the measurement
  2. Place the cuff on the bare upper arm at heart level Correct answer.
  3. Have the client stand during the reading
  4. Place the cuff over the client's long sleeve

Explanation

The cuff should go on bare skin with the bladder centered over the brachial artery and the arm supported at heart level. Clothing under the cuff or an unsupported arm can distort the reading. The client should rest quietly and avoid talking during the measurement.

Question 30Certification content area (not enumerated in source)

A client is on intake and output monitoring. Which item should the nurse aide record as intake?

  1. Ice chips eaten by the client Correct answer.
  2. Vomit collected in an emesis basin
  3. Fluid from a wound dressing
  4. Urine emptied from a bedpan

Explanation

Intake includes anything the client takes by mouth, including ice chips, which are counted as fluid. Output includes urine, vomit, wound drainage, and other fluids leaving the body. Recording the two categories separately keeps the balance accurate.

Question 31Certification content area (not enumerated in source)

A nurse aide is told a client has a latex allergy. Which action is most appropriate?

  1. Use non-latex gloves for the client's care Correct answer.
  2. Ask the client to confirm the allergy each shift
  3. Wear latex gloves but wash hands afterward
  4. Use latex gloves only for brief tasks

Explanation

For a client with a latex allergy, latex-containing products should be avoided entirely and non-latex gloves used. Brief contact or handwashing after use does not prevent a reaction. The allergy should already be documented and communicated, not re-confirmed each shift.

Question 32Certification content area (not enumerated in source)

A nurse aide is caring for a client with an intravenous line in the arm. Which action is appropriate during routine care?

  1. Cover the insertion site with a thick blanket
  2. Loosen the tubing connection to check the flow
  3. Keep the tubing free of kinks and the site visible Correct answer.
  4. Move the arm rapidly during repositioning

Explanation

The nurse aide should protect the IV by keeping tubing unkinked and the site visible so problems can be noticed. The aide should not adjust connections or the rate, which are the nurse's responsibility. Hiding the site or jerking the arm risks dislodging the catheter.

Question 33Certification content area (not enumerated in source)

A nurse aide is assisting a client to walk with a gait belt. Where should the belt be placed?

  1. Around the client's thighs
  2. Loose around the client's chest
  3. Under the client's arms
  4. Snug around the client's waist Correct answer.

Explanation

A gait belt is fastened snugly around the waist so the aide can steady the client without pulling on the arms or clothing. It should be tight enough not to slide but not so tight that breathing is restricted. Placing it elsewhere reduces control and safety.

Question 34Certification content area (not enumerated in source)

A client who has difficulty swallowing is eating. Which position is safest for this client during the meal?

  1. Sitting upright in a chair or high in bed Correct answer.
  2. Reclining at a 15-degree angle
  3. Lying on the left side
  4. Lying flat on the back

Explanation

An upright position, ideally seated in a chair or with the head of the bed raised high, helps food move safely down the throat. Lying flat or reclining increases the risk of choking and aspiration. The client should remain upright for a period after eating as well.

Question 35Certification content area (not enumerated in source)

A nurse aide notices a client's urine is dark amber and has a strong odor. Which action is most appropriate?

  1. Restrict the client's fluids
  2. Report the observation to the nurse Correct answer.
  3. Ignore it because urine color varies
  4. Apply a moisture barrier cream

Explanation

Dark, strong-smelling urine may signal dehydration or infection and should be reported to the nurse. The aide does not diagnose but communicates changes in the client's condition. Restricting fluids could worsen dehydration, and barrier cream does not address the cause.

Question 36Certification content area (not enumerated in source)

A nurse aide is caring for a client who has just returned from surgery. Which finding should be reported to the nurse right away?

  1. A gradual increase in drainage on the dressing Correct answer.
  2. A temperature of 98.6 F (37 C)
  3. A pulse of 72 beats per minute
  4. A desire to sleep after the procedure

Explanation

Increasing drainage on a surgical dressing may indicate bleeding and should be reported promptly. Stable vital signs and a wish to rest after surgery are expected findings. The aide reports changes rather than waiting for them to worsen.

Question 37Certification content area (not enumerated in source)

A nurse aide is assigned to collect a sputum specimen. Which action supports a good sample?

  1. Collect saliva from the mouth
  2. Collect the specimen early in the morning before breakfast Correct answer.
  3. Collect the specimen after the client eats
  4. Collect the specimen in a dry, unlabeled cup

Explanation

Sputum specimens are best collected in the morning before eating, when secretions have pooled. The client should cough deeply to bring up material from the lungs rather than spitting saliva. The container must be clean and labeled with the client's information.

Question 38Certification content area (not enumerated in source)

A client has an order for a low-sodium diet. Which food choice best follows this diet?

  1. Canned soup with crackers
  2. Salted pretzels
  3. Pickled vegetables
  4. Fresh fruit salad with no added salt Correct answer.

Explanation

A low-sodium diet limits salt, so fresh foods without added salt are the best choice. Canned, pickled, and salted snack foods are typically high in sodium. Reading labels and choosing fresh items helps the client stay within the restriction.

Question 39Certification content area (not enumerated in source)

A nurse aide is providing mouth care for a client who is unconscious. Which action is correct?

  1. Turn the client's head to the side and use small amounts of fluid Correct answer.
  2. Use a hard toothbrush with full-strength mouthwash
  3. Leave the mouth open without cleaning the inside
  4. Place the client flat on the back and use plenty of water

Explanation

For an unconscious client, the head is turned to the side and only small amounts of fluid are used to prevent choking. The mouth should be cleaned gently with a soft swab or brush. The client cannot swallow or protect the airway, so caution is essential.

Question 40Certification content area (not enumerated in source)

A client is at risk for falls and uses a walker. Which action best reduces the client's risk?

  1. Keep the call light and personal items within reach Correct answer.
  2. Place the walker far from the bed
  3. Raise all four side rails on the bed
  4. Keep the room dim to encourage rest

Explanation

Keeping the call light and needed items within reach reduces the chance that the client will try to get up unsafely. The environment should be well lit and free of clutter. The walker should be close at hand so the client can use it correctly.

Question 41Certification content area (not enumerated in source)

A client who is terminally ill says, "I don't want any more treatments." What should the nurse aide do?

  1. Listen respectfully and report the statement to the nurse Correct answer.
  2. Promise the client that treatments will stop
  3. Share the statement with other clients
  4. Tell the client that giving up is wrong

Explanation

The aide should listen without judgment and report the client's statement to the nurse so the care team can address it. The aide does not decide about treatments or make promises. Respecting the client's wishes and privacy is part of dignified care.

Question 42Certification content area (not enumerated in source)

A client has an indwelling catheter and the drainage bag is full. Which action should the nurse aide take?

  1. Empty the bag and record the amount and character of urine Correct answer.
  2. Leave the bag full until the next shift
  3. Disconnect the tubing to pour out the urine
  4. Raise the bag above the bladder to speed drainage

Explanation

A full drainage bag should be emptied, and the amount and appearance of the urine recorded. The bag must stay below the level of the bladder to prevent backflow of urine. Disconnecting the tubing breaks the closed system and increases infection risk.

Question 43Certification content area (not enumerated in source)

A nurse aide is transferring a client from bed to a chair. Which action protects the aide's back?

  1. Lean forward from the waist to lift
  2. Twist at the waist while lifting
  3. Bend the knees and keep the client close to the body Correct answer.
  4. Hold the client at arm's length

Explanation

Safe lifting uses the leg muscles, with knees bent and the client held close to the aide's body. Twisting or reaching out with straight arms strains the back. The aide should also use a gait belt and get help when needed.

Question 44Certification content area (not enumerated in source)

A nurse aide observes a client's skin over the tailbone is red and does not blanch when pressed. What does this finding suggest?

  1. A sign that the client is well hydrated
  2. Early pressure damage that should be reported Correct answer.
  3. A normal variation that needs no action
  4. A sunburn from recent outdoor activity

Explanation

Redness that does not blanch when pressed is an early sign of pressure damage and should be reported to the nurse. The area should be kept clean, dry, and off-loaded. Documentation and prompt reporting allow the care plan to be adjusted.

Question 45Certification content area (not enumerated in source)

A client is receiving a tube feeding. Which action is appropriate for the nurse aide?

  1. Flush the tube with a large volume of air
  2. Lay the client flat during the feeding
  3. Adjust the feeding rate without an order
  4. Elevate the head of the bed during and after the feeding Correct answer.

Explanation

Keeping the head of the bed elevated during and after a tube feeding reduces the risk of aspiration. The aide should not change the rate, which is set by the nurse or prescriber. Flushing with air is not a standard practice and can cause discomfort.

Question 46Certification content area (not enumerated in source)

A nurse aide is caring for a client who has hearing loss in both ears. Which approach best supports communication?

  1. Speak rapidly to finish quickly
  2. Shout directly into the client's ear
  3. Cover the mouth while speaking
  4. Face the client and speak clearly at a normal volume Correct answer.

Explanation

Facing the client allows lip reading and clearer sound, and speaking clearly at a normal volume is more helpful than shouting. The mouth should stay visible, and speech should be unhurried. Good lighting and reduced background noise also help.

Question 47Certification content area (not enumerated in source)

A client has an order for a pureed diet. Which food is most appropriate?

  1. Grilled chicken breast
  2. Whole wheat toast
  3. Raw carrot sticks
  4. Mashed potatoes with gravy Correct answer.

Explanation

A pureed diet includes foods blended to a smooth texture, such as mashed potatoes with gravy. Whole, raw, or fibrous foods are difficult to chew and swallow safely. The diet is chosen for clients with chewing or swallowing problems.

Question 48Certification content area (not enumerated in source)

A nurse aide is assisting a client with a bedpan. Which action best supports the client's safety and comfort?

  1. Leave the client alone without a call light
  2. Warm the bedpan and place it under the client with the wide end toward the feet Correct answer.
  3. Raise the head of the bed fully during use
  4. Place the bedpan with the narrow end toward the feet

Explanation

A warmed bedpan is more comfortable, and the wide end is placed under the buttocks with the narrow end toward the feet. The client should be able to call for help and should not be left unattended without a call light. Proper positioning prevents spills and discomfort.

Question 49Certification content area (not enumerated in source)

A client's family asks the nurse aide to explain the client's new medication. What is the best response?

  1. Explain that the nurse will answer questions about the medication Correct answer.
  2. Read the medication label aloud to the family
  3. Tell the family to look up the drug online
  4. Give a detailed explanation from memory

Explanation

Explaining medications is the nurse's responsibility, so the aide should refer the family to the nurse. The aide may listen and offer support but should not give medical information. This protects the client and keeps roles within scope.

Question 50Certification content area (not enumerated in source)

A nurse aide notes that a client's respirations are shallow and the client seems restless. Which action should the aide take?

  1. Report the findings to the nurse promptly Correct answer.
  2. Record the findings and take no further action
  3. Encourage the client to sleep
  4. Wait until the next scheduled vital signs

Explanation

Shallow respirations with restlessness may signal hypoxia and require prompt reporting. The aide should stay with the client and notify the nurse rather than waiting. Early communication allows rapid assessment and treatment.
