2023 Practice CNA Exam Questions and Rationales

Aspiring Certified Nursing Assistants (CNAs) play a crucial role in the healthcare industry, providing essential support and care to patients and residents. To help you prepare for the CNA exam in 2023, we have compiled a set of practice questions along with detailed rationales for each answer. These questions cover various topics that are commonly tested in the CNA exam. Let’s get started:

Question 1

Which vital sign should a CNA report immediately to the nurse?

A) Temperature of 98.6°F (37°C)

B) Heart rate of 70 beats per minute

C) Respiratory rate of 18 breaths per minute

D) Blood pressure of 130/80 mmHg

Rationale:

The correct answer is D) Blood pressure of 130/80 mmHg. A blood pressure reading above the normal range can be a cause for concern, and the CNA should report it immediately to the nurse for further evaluation and possible intervention.

Question 2

When providing oral care to an unconscious patient, the CNA should:

A) Use a swab dipped in water to clean the patient’s mouth

B) Avoid oral care as it may cause discomfort to the patient

C) Position the patient on their side to prevent aspiration

D) Administer oral care using an alcohol-based mouthwash

Rationale:

The correct answer is C) Position the patient on their side to prevent aspiration. When providing oral care to an unconscious patient, it is essential to position them on their side (recovery position) to prevent choking or aspiration of fluids.

Question 3

Which of the following is an appropriate technique for transferring a patient from the bed to a wheelchair?

A) Lift the patient using your back muscles

B) Slide the patient to the edge of the bed using a sheet

C) Ask the patient to stand up and walk to the wheelchair with assistance

D) Use a transfer belt and assist the patient to a standing position

Rationale:

The correct answer is D) Use a transfer belt and assist the patient to a standing position. Using a transfer belt helps provide stability and support during the transfer process, reducing the risk of falls and injuries.

Question 4

A patient with diabetes is experiencing low blood sugar levels (hypoglycemia). What should the CNA do?

A) Offer the patient a sugary drink or candy

B) Elevate the patient’s legs to improve blood flow

C) Assist the patient in injecting insulin

D) Report the situation to the nurse immediately

Rationale:

The correct answer is A) Offer the patient a sugary drink or candy. In cases of hypoglycemia, providing a quick source of sugar can help raise blood sugar levels. However, if the patient is unconscious or unable to swallow, the nurse should be notified immediately.

Question 5

A patient is at risk of developing pressure ulcers. What should the CNA do to prevent them?

A) Keep the patient’s skin dry and moisturized

B) Encourage the patient to sit for extended periods

C) Massage bony prominences to promote blood circulation

D) Reposition the patient at least every two hours

Rationale:

The correct answer is D) Reposition the patient at least every two hours. Regular repositioning helps relieve pressure on vulnerable areas, reducing the risk of pressure ulcers. Additionally, keeping the patient’s skin dry and moisturized can contribute to skin health.
