CNA Practice Test: Video 4 Answers (25 Questions) — Questions and Answers

Question 1: The Heimlich maneuver (abdominal thrusts) is used for a client who has

fallen out of bed
impaired eyesight
a blocked airway (Correct answer)
a bloody nose

Correct answer: a blocked airway

The Heimlich maneuver, also known as abdominal thrusts, is an emergency procedure specifically used when a person's airway is blocked by a foreign object, causing them to choke. It is designed to dislodge the obstruction and restore breathing by applying upward pressure to the diaphragm.

Question 2: Which is the most accurate way to measure a resident’s temperature?

Oral
Rectal (Correct answer)
Axillary
Ear

Correct answer: Rectal

Rectal temperature is generally considered the most accurate method for measuring core body temperature because the rectum is a closed cavity that closely reflects the body's internal temperature. It is less influenced by external factors compared to oral, axillary, or ear temperatures, providing a more precise reading.

Question 3: The branch of medicine concerned with the problems and diseases of the elderly is called _______.

orthopedics
obstetrics
geriatrics (Correct answer)
pediatrics

Correct answer: geriatrics

Geriatrics is the specialized branch of medicine that focuses on the health and care of older adults. It addresses the unique physiological, psychological, and social problems associated with aging, including the prevention and treatment of age-related diseases and disabilities.

Question 4: A normal adult blood pressure is

134/90
80/40
180/80
116/70 (Correct answer)

Correct answer: 116/70

A normal adult blood pressure reading is generally considered to be less than 120 mmHg systolic and less than 80 mmHg diastolic. The reading 116/70 mmHg falls perfectly within this healthy range, indicating optimal cardiovascular function. Readings significantly higher or lower than this range can indicate hypertension or hypotension, respectively.

Question 5: How should a CNA respond to a patient who refuses care?

Ignore the refusal
Persuade until they agree
Inform the nurse and respect the decision (Correct answer)
Force the care to be given

Correct answer: Inform the nurse and respect the decision

Patients have the right to refuse care, and their autonomy must be respected. If a patient refuses care, the CNA should inform the nurse immediately so the nurse can assess the situation, explain the potential consequences, and explore alternatives, ensuring the patient's rights are upheld while still prioritizing their well-being.

Question 6: While an unsteady resident is showering you should

leave to respect the client's privacy.
ambulate another resident while you wait.
go start another client's shower.
have the client use a shower chair. (Correct answer)

Correct answer: have the client use a shower chair.

An unsteady resident is at a high risk of falls, especially in a wet and slippery environment like a shower. Providing a shower chair offers a stable and secure seating option, significantly reducing the risk of falling. This ensures the resident's safety while allowing them to maintain hygiene with assistance.

Question 7: To clean a resident's eyeglasses, what should you do?

Clean the glasses with warm water. (Correct answer)
Dry the lens with an abrasive cloth.
Use liquid soap that contains lotion.
Allow the eyeglasses to air dry.

Correct answer: Clean the glasses with warm water.

Cleaning eyeglasses with warm water is the safest and most effective method to remove dirt and smudges without scratching the lenses. Using abrasive cloths can damage the lens coating, liquid soaps with lotion can leave residue, and air drying can result in water spots. A gentle rinse with warm water followed by drying with a soft, clean cloth is recommended.

Question 8: Which of the following WILL NOT assist bowel elimination?

eating more foods with fiber
taking a walk
drinking a lot of water
increasing dairy and sugar intake (Correct answer)

Correct answer: increasing dairy and sugar intake

Increasing dairy and sugar intake will generally not assist bowel elimination and can sometimes worsen constipation for some individuals. Foods high in fiber, adequate fluid intake, and physical activity are key components that promote regular bowel movements. Dairy and sugar lack the fiber and hydration needed for healthy digestion.

Question 9: When helping a disabled person with ADLs, the nursing assistant should

Encourage the person to watch in order to learn
Do everything for the person in order to save time
Avoid praise and positive feedback
Encourage as much participation as possible (Correct answer)

Correct answer: Encourage as much participation as possible

Encouraging a disabled person to participate as much as they can in their Activities of Daily Living (ADLs) promotes their independence, self-esteem, and preserves their functional abilities. Doing everything for them can lead to learned helplessness and a decline in their existing skills. The goal is to assist, not to take over, fostering dignity and autonomy.

Question 10: Which device does NOT make toileting easier?

Elevated toilet seat
Egg crate toilet cover (Correct answer)
Grab bars on the wall next to the toilet
Bedside commode

Correct answer: Egg crate toilet cover

Elevated toilet seats, grab bars, and bedside commodes are all devices designed to make toileting easier and safer for individuals with mobility issues. An egg crate toilet cover, however, is typically used for pressure relief on a bed or chair, not for facilitating the act of toileting itself. It does not aid in transfers or stability.

Question 11: Exercises that can help maintain the movement of joints are called

Range of motion (Correct answer)
Abduction and adduction
Muscle endurance methods
Joint effectiveness techniques

Correct answer: Range of motion

Range of motion (ROM) exercises are specifically designed to move a joint through its full extent of movement. These exercises help to maintain joint flexibility, prevent stiffness, and improve circulation. They are essential for residents who have limited mobility to prevent contractures and promote overall physical function.

Question 12: Restorative nursing care is the process of

Focusing specifically on what the resident cannot do.
Providing care for the needs of the whole person. (Correct answer)
Restoring resident rights for those who haven't had them.
Doing everything we can to prevent fatigue.

Correct answer: Providing care for the needs of the whole person.

Restorative nursing care emphasizes a holistic approach, focusing on the resident's overall well-being and maximizing their functional abilities. It aims to help residents regain or maintain their highest possible level of independence in all aspects of their lives. This includes physical, mental, and social needs, rather than just focusing on limitations or preventing fatigue.

Question 13: Equipment used to help the resident maintain correct body alignment includes all of the following EXCEPT

cones (Correct answer)
splints
foot supports
bed cradles

Correct answer: cones

Splints, bed cradles, and foot supports are all devices specifically designed to help maintain correct body alignment, prevent deformities, and support limbs. Cones, however, are not typically used for maintaining body alignment in this context. They might be used for other purposes, but not for the primary goal of alignment support.

Question 14: While helping a resident perform a Range of Motion (ROM) exercise, he complains of pain. The nurse aide should

ask the nurse to give a pain medication.
repeat the ROM exercise to see if it happens again.
ask to receive more training in ROM techniques.
stop the exercise at that point and tell the nurse. (Correct answer)

Correct answer: stop the exercise at that point and tell the nurse.

If a resident complains of pain during a Range of Motion (ROM) exercise, it indicates a potential injury or discomfort that should not be ignored. The nurse aide must immediately stop the exercise to prevent further harm and report the complaint to the nurse, who can assess the situation and determine the appropriate course of action.

Question 15: ROM exercises will help prevent

Pressure sores
Obesity
Depression
Contractures (Correct answer)

Correct answer: Contractures

Range of motion (ROM) exercises are crucial for preventing contractures, which are the permanent shortening of muscles and tendons, leading to stiffness and limited joint movement. By regularly moving joints through their full range, ROM exercises maintain flexibility, improve circulation, and prevent the tissues from becoming rigid and fixed. This helps preserve mobility and function.

Question 16: After cleaning a resident's dentures, you remove and discard your gloves. What is the next step?

Pull back the resident's privacy curtain.
Proceed to your next assigned resident.
Wash your hands. (Correct answer)
Help the resident insert their dentures.

Correct answer: Wash your hands.

Even after removing gloves, there is always a risk of microscopic contamination from the gloves themselves or from contact with the soiled item. Handwashing is the single most effective way to remove any remaining pathogens and prevent their spread. This critical step ensures proper infection control and breaks the chain of infection after completing a task involving potential exposure to bodily fluids or contaminants.

Question 17: During dinner, a client who is HIV-positive accidentally breaks a glass and cuts himself. What is the proper procedure?

Block off the area until it can be cleaned. (Correct answer)
Call the paramedics to treat the client.
Use a long-handled mop to wipe up the blood.
Begin to fill out an Incident Report.

Correct answer: Block off the area until it can be cleaned.

A broken glass with blood presents both a biohazard and a physical hazard. Blocking off the area immediately prevents others from stepping on glass or coming into contact with the blood, which is considered potentially infectious under standard precautions. This allows for a safe and controlled environment for proper cleanup using appropriate personal protective equipment (PPE) and disinfection protocols.

Question 18: When caring for a patient with MRSA, the nurse aide should wear

surgical goggles
rebreather mask
sterile isolation suit
gown and gloves (Correct answer)

Correct answer: gown and gloves

MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacteria often spread through direct contact with an infected person or contaminated surfaces. To prevent its transmission, healthcare workers must implement contact precautions, which specifically require wearing a gown and gloves when entering the patient's room or having direct contact with the patient or their environment. This barrier prevents the bacteria from contaminating the aide's clothing or hands.

Question 19: All body fluids are considered infectious EXCEPT

saliva
sweat (Correct answer)
blood
semen

Correct answer: sweat

Under standard precautions, all body fluids are treated as potentially infectious for bloodborne pathogens, with the notable exception of sweat. While sweat can contain some microorganisms from the skin, it is not considered a vehicle for transmitting serious bloodborne diseases like HIV or Hepatitis B and C. Therefore, it is generally not classified as an infectious body fluid in the same way as blood, semen, or saliva (especially if blood is present).

Question 20: Used disposable supplies and equipment should be discarded

in the resident’s wastebasket.
in a designated receptacle. (Correct answer)
outside the resident's room.
in the clean utility room.

Correct answer: in a designated receptacle.

Used disposable supplies and equipment are often contaminated with bodily fluids or pathogens and pose an infection risk. Discarding them in a designated receptacle, such as a biohazard bin or a sharps container, ensures they are handled safely and disposed of according to facility policies and regulations. This practice prevents accidental exposure to pathogens, minimizes environmental contamination, and maintains a clean, safe environment for everyone.

Question 21: Which of the following would cause an inaccurate pulse oximetry reading?

The probe is at room temperature
The resident is lying still
The resident has dark nail polish on the finger (Correct answer)
The probe is on the index finger

Correct answer: The resident has dark nail polish on the finger

Dark nail polish, artificial nails, or poor circulation can interfere with the light sensor in a pulse oximeter, causing falsely low or inaccurate readings.

Question 22: A normal SpO2 reading for a healthy adult is:

100–105%
95–100% (Correct answer)
90–94%
85–90%

Correct answer: 95–100%

Normal oxygen saturation (SpO2) for a healthy adult is 95–100%. Values below 90% are considered dangerously low and require immediate reporting.

Question 23: When taking a blood pressure on a resident who recently exercised, the CNA should:

Use a smaller cuff
Wait at least 5–10 minutes for the resident to rest first (Correct answer)
Take it immediately
Take it on both arms and average the results

Correct answer: Wait at least 5–10 minutes for the resident to rest first

Exercise temporarily elevates blood pressure. Waiting 5–10 minutes allows the cardiovascular system to return toward baseline, producing a more accurate resting measurement.

Question 24: What is the normal resting heart rate range for an adult?

120–140 beats per minute
100–120 beats per minute
60–100 beats per minute (Correct answer)
40–60 beats per minute

Correct answer: 60–100 beats per minute

A normal adult resting heart rate is 60–100 beats per minute. Values outside this range may indicate bradycardia or tachycardia and should be reported.

Question 25: The apical pulse is measured:

At the wrist over the radial artery
At the neck over the carotid artery
At the groin over the femoral artery
At the apex of the heart using a stethoscope (Correct answer)

Correct answer: At the apex of the heart using a stethoscope

The apical pulse is listened to with a stethoscope placed at the apex of the heart (left midclavicular line, 5th intercostal space). It is counted for a full minute.
