CNA Practice Test: Video 8 Answers (25 Questions) — Questions and Answers

Question 1: When muscles atrophy, they become

Smaller (Correct answer)
Stretched
Hardened
Larger

Correct answer: Smaller

When muscles atrophy, they become smaller and weaker due to disuse, disease, or aging. This reduction in muscle mass can lead to decreased strength and impaired mobility. Regular exercise and proper nutrition are important for preventing or slowing muscle atrophy.

Question 2: Meal trays have arrived. Before serving each tray the nurse aide should

ask patients if they are hungry.
check the temperature of the food.
check each armband, even on familiar patients. (Correct answer)
ask about dietary restrictions.

Correct answer: check each armband, even on familiar patients.

Patient identification is a critical safety measure to prevent medication errors and ensure the correct patient receives the correct meal. Even if a patient is familiar, verifying their identity against the armband prevents errors that could arise from similar names, room changes, or temporary memory lapses, upholding patient safety standards.

Question 3: Which of the following has to be reported right away?

A pulse of 90
A blood pressure of 90/40 (Correct answer)
Temperature of 99.4
Respirations of 12

Correct answer: A blood pressure of 90/40

A blood pressure of 90/40 mmHg is significantly low (hypotension) and indicates a potentially serious medical condition, such as shock, dehydration, or internal bleeding. This vital sign deviation requires immediate reporting to the nurse because it can lead to inadequate blood flow to vital organs, causing dizziness, confusion, and rapid deterioration of the patient's condition. The other options are generally within normal or mildly abnormal ranges that do not typically require immediate reporting.

Question 4: A Hepatitis B vaccination protects the person receiving it against a disease that affects

heart
liver (Correct answer)
skin
kidneys

Correct answer: liver

The Hepatitis B vaccination protects against the Hepatitis B virus, which primarily infects the liver. This virus can cause acute or chronic liver inflammation, leading to severe conditions like cirrhosis, liver failure, or liver cancer. Vaccination is a critical preventive measure, especially for healthcare workers who are at higher risk of exposure.

Question 5: The Foley bag must be kept lower than the patient’s bladder because

it will be out of sight to visitors.
it makes the client more comfortable in bed.
it prevents urine returning to the bladder. (Correct answer)
it is easier to empty the bag.

Correct answer: it prevents urine returning to the bladder.

The Foley catheter drainage bag must always be kept lower than the patient’s bladder to ensure proper urine drainage by gravity. If the bag is raised above the bladder, urine can flow backward into the bladder, significantly increasing the risk of urinary tract infections due to reflux of stagnant urine.

Question 6: When assisting a blind resident to walk it is important to

have the resident use a white cane.
allow the resident to hold your arm. (Correct answer)
hold the resident's elbow.
stand slightly behind the resident.

Correct answer: allow the resident to hold your arm.

When assisting a blind resident to walk, it is important to allow them to hold your arm, usually just above the elbow. This position allows the resident to follow your movements and feel changes in direction or elevation, providing them with a sense of security and control. You should walk slightly ahead of them, guiding them safely.

Question 7: Before giving a back rub, the bottle of lotion can be placed in a basin of hot water for several minutes so that

The lotion will not be cold (Correct answer)
The lotion will be easier to apply
The bottle is sanitary
The lotion will relieve itching

Correct answer: The lotion will not be cold

Applying cold lotion directly to a client's skin can be startling and uncomfortable, especially for elderly or sensitive individuals. Warming the lotion slightly before application enhances the therapeutic and relaxing effects of a back rub. This simple step contributes to the client's comfort and overall positive experience during care.

Question 8: When transferring a client to a different unit, the MOST important information the nurse aide needs from the nurse is the

client’s medical diagnosis.
phone number to the client’s room.
name and room number. (Correct answer)
name of the client’s spouse.

Correct answer: name and room number.

When transferring a client to a different unit, the most important information the nurse aide needs from the nurse is the client's name and new room number. This ensures the correct client is transferred to the correct location, preventing errors and maintaining patient safety. While other information is important for care, the name and room number are critical for the physical transfer itself.

Question 9: A sitz bath is helpful

when residents refuse to take a shower.
when a patient has been sitting for too long.
after all surgical procedures.
after rectal surgery. (Correct answer)

Correct answer: after rectal surgery.

A sitz bath is specifically designed to provide therapeutic relief and promote healing in the perineal and anal areas. The warm water helps to increase blood flow, reduce pain, and soothe discomfort, making it particularly beneficial after rectal surgery, hemorrhoidectomies, or childbirth. It is not a general bath alternative or a treatment for prolonged sitting.

Question 10: A nurse aide should give an unconscious client oral hygiene at LEAST every

6 hours
4 hours
2 hours (Correct answer)
8 hours

Correct answer: 2 hours

Unconscious clients are at high risk for aspiration pneumonia and oral infections due to decreased saliva production and inability to perform their own oral care. Frequent oral hygiene, at least every two hours, helps keep the mouth clean, moist, and free from pathogens. This regular care is crucial for preventing complications and maintaining oral health.

Question 11: A resident is learning to dress herself after a stroke affecting her right arm. The CNA should assist her to dress the affected arm:

At the same time as the unaffected arm
Last, after the unaffected arm is dressed
First, before the unaffected arm (Correct answer)
Only if the resident requests help

Correct answer: First, before the unaffected arm

When dressing residents with a weak or affected limb, the affected side is always dressed first.

Question 12: Residents who are bedridden face all following risks EXCEPT

Calcium loss
Increased muscle strength (Correct answer)
Blood clots
Pneumonia

Correct answer: Increased muscle strength

Residents who are bedridden are at risk for numerous complications due to immobility, including calcium loss from bones, blood clots (deep vein thrombosis), and pneumonia (due to decreased lung expansion). However, prolonged inactivity leads to muscle atrophy and weakness, not increased muscle strength. Therefore, increased muscle strength is the risk they do NOT face.

Question 13: What is the branch of medicine that deals with physical medicine and rehabilitation called?

Physiology
Physiatry (Correct answer)
Psychiatry
Podiatry

Correct answer: Physiatry

Physiatry is the specialized branch of medicine focused on physical medicine and rehabilitation. Physiatrists diagnose and treat conditions affecting the brain, spinal cord, nerves, bones, joints, ligaments, muscles, and tendons, aiming to restore function and quality of life. The other options are different medical specialties.

Question 14: When is an easy time to do Range of motion (ROM) exercises?

Before going to sleep
During the resident's bath (Correct answer)
While getting dressed
When the resident wakes up

Correct answer: During the resident's bath

Performing Range of Motion (ROM) exercises during a resident's bath is an efficient and practical time. The warm water can help relax muscles, making movements easier and more comfortable, and it integrates the exercises into an existing care routine, ensuring they are consistently performed.

Question 15: When helping a client who is recovering from a stroke to walk, the nurse aide should assist

On the client’s weak side (Correct answer)
From behind the client
With a wheelchair
On the client’s strong side

Correct answer: On the client’s weak side

When assisting a client recovering from a stroke, the nurse aide should stand on the client's weak side. This position allows the aide to provide direct support to the affected side, helping to maintain balance and prevent falls. Supporting the strong side would be less effective in preventing instability.

Question 16: Which vital sign is monitored to assess breathing effectiveness?

Respirations (Correct answer)
Temperature
Pulse
Blood pressure

Correct answer: Respirations

Respirations (breathing rate, depth, and rhythm) are monitored to assess the effectiveness of the respiratory system in delivering oxygen and removing carbon dioxide.

Question 17: How long should a CNA count an irregular pulse?

15 seconds and multiply by 4
30 seconds and multiply by 2
Until it becomes regular
A full 60 seconds (Correct answer)

Correct answer: A full 60 seconds

An irregular pulse should be counted for a full 60 seconds to ensure accuracy, as shorter counting periods may magnify errors when the rate is inconsistent.

Question 18: The term 'bradycardia' refers to:

Heart rate above 100 bpm
Irregular heartbeat
Heart rate below 60 bpm (Correct answer)
Absence of a pulse

Correct answer: Heart rate below 60 bpm

Bradycardia is a heart rate below 60 beats per minute. It may cause dizziness, fatigue, or fainting and should be reported to the nurse.

Question 19: Pulse oximetry measures:

Blood glucose level
Oxygen saturation in the blood (Correct answer)
Carbon dioxide level
Blood pressure

Correct answer: Oxygen saturation in the blood

Pulse oximetry measures the percentage of hemoglobin saturated with oxygen (SpO2). Normal values are typically 95–100%.

Question 20: Normal adult blood pressure is considered to be:

90/60 mmHg
120/80 mmHg (Correct answer)
140/90 mmHg
160/100 mmHg

Correct answer: 120/80 mmHg

120/80 mmHg is considered normal adult blood pressure. The top number (systolic) represents pressure when the heart beats; the bottom (diastolic) when it rests.

Question 21: It is appropriate for a nurse aide to share the information regarding a client’s status with

Anyone who knows the client
The client’s family members
The client’s roommate
The staff on the next shift (Correct answer)

Correct answer: The staff on the next shift

Sharing client information is governed by HIPAA and the principle of confidentiality. A nurse aide can only share information with other healthcare professionals directly involved in the client's care, such as the staff on the next shift, to ensure continuity of care. Sharing information with family, friends, or roommates without explicit consent violates the client's privacy rights.

Question 22: It is appropriate for a nurse aide to share the information regarding a client’s status with

the staff on the next shift. (Correct answer)
the client’s roommate.
the client’s family members.
social media friends.

Correct answer: the staff on the next shift.

Sharing client information with the staff on the next shift is appropriate because it ensures continuity of care and allows the healthcare team to provide consistent, informed support. This is a professional exchange within the healthcare setting, unlike sharing with unauthorized individuals like roommates, family without consent, or social media friends, which would violate patient confidentiality (HIPAA).

Question 23: Clients have the right to

Go anywhere in the facility
See other clients’ medical reports
Smoke in any area of the facility
Have access to a telephone (Correct answer)

Correct answer: Have access to a telephone

Residents in long-term care facilities have the right to communicate privately with people outside the facility, which includes access to a telephone. This right is part of maintaining their connections to family and friends and exercising their autonomy. The facility must provide reasonable access to a phone to facilitate these communications.

Question 24: When giving care to a client, the nurse aide should avoid unnecessary exposure of the client in order to protect the client’s right to

personal hygiene.
personal choice.
privacy. (Correct answer)
confidentiality.

Correct answer: privacy.

Unnecessary exposure of a client during care directly violates their right to privacy and dignity. CNAs are responsible for ensuring that clients are covered and that their bodies are not exposed more than necessary during procedures like bathing, dressing, or examinations. This practice helps maintain their personal space and respect, upholding their right to privacy.

Question 25: On admission to a nursing home or a long-term care facility, a resident must be given

an Informed Consent document.
the facility's monthly menu.
the activity and worship schedules.
a copy of the Resident Bill of Rights. (Correct answer)

Correct answer: a copy of the Resident Bill of Rights.

Upon admission to a nursing home or long-term care facility, federal law (OBRA '87) mandates that residents receive a copy of the Resident Bill of Rights. This ensures they are fully aware of their legal rights regarding care, privacy, dignity, and participation in decisions affecting their well-being. Providing this document empowers residents to advocate for themselves and understand their entitlements.
