CNA Basic Nursing Skills 1 — Questions and Answers

Question 1: What is the primary purpose of hand hygiene in nursing care?

To keep hands moisturized
To prevent transmission of infections (Correct answer)
To remove visible dirt only
To comply with hospital dress code

Correct answer: To prevent transmission of infections

Hand hygiene, including washing and sanitizing, is the most effective way to break the chain of infection in healthcare settings. It removes transient microorganisms that can cause illness, protecting both patients and healthcare workers. This practice is crucial for preventing the transmission of pathogens and maintaining a safe environment.

Question 2: How often should a CNA reposition a bed-bound patient?

Every 30 minutes
Every 2 hours (Correct answer)
Once per shift
Only when requested

Correct answer: Every 2 hours

Repositioning bed-bound patients every two hours is a critical intervention to prevent pressure ulcers (bedsores). This schedule helps redistribute pressure on bony prominences, promoting circulation and preventing prolonged compression of tissues. Regular repositioning is essential for maintaining skin integrity and patient comfort.

Question 3: What is the correct way to measure a patient’s respiratory rate?

Count for 15 seconds and multiply by 4
Ask the patient to count breaths
Watch the chest rise and fall for 60 seconds (Correct answer)
Estimate based on activity

Correct answer: Watch the chest rise and fall for 60 seconds

To accurately measure a patient's respiratory rate, a CNA should observe the chest rise and fall for a full 60 seconds. This method accounts for irregular breathing patterns and ensures a precise count, as counting for shorter periods and multiplying can lead to inaccuracies. It's important to do this discreetly, as patients may alter their breathing if they know it's being observed.

Question 4: Why is it important to monitor fluid intake and output?

To track food preferences
To identify patient appetite
To monitor hydration and kidney function (Correct answer)
To limit fluid intake

Correct answer: To monitor hydration and kidney function

Monitoring fluid intake and output (I&O) is vital for assessing a patient's hydration status and kidney function. It helps identify imbalances like dehydration or fluid overload, which can significantly impact health. This data provides crucial information for the nursing team to make informed decisions about patient care and treatment plans.

Question 5: What should you do if a patient begins to fall while ambulating?

Hold the patient upright at all costs
Guide them gently to the floor (Correct answer)
Yell for help and let go
Try to pick them up immediately

Correct answer: Guide them gently to the floor

If a patient begins to fall, the safest action is to guide them gently to the floor, rather than attempting to hold them upright. This technique minimizes the impact of the fall, reducing the risk of serious injury to the patient and preventing injury to the CNA. The CNA should widen their stance, support the patient, and ease them down while protecting their head.

Question 6: Which is the most accurate method to take a patient's temperature?

Oral
Axillary
Rectal (Correct answer)
Forehead

Correct answer: Rectal

Rectal temperature is considered the most accurate method for measuring core body temperature because it reflects the internal body temperature most closely. This site is less affected by external factors compared to oral or axillary readings. While often invasive, it provides a reliable measurement, especially when precision is critical for diagnosis or monitoring.

Question 7: What is the best way to prevent pressure ulcers?

Use of heating pads
Frequent repositioning and skin care (Correct answer)
Increased oral intake
Apply cold packs

Correct answer: Frequent repositioning and skin care

The best way to prevent pressure ulcers (bedsores) is through frequent repositioning and meticulous skin care. Repositioning every two hours relieves pressure on vulnerable areas, while daily skin assessment, cleaning, and moisturizing maintain skin integrity. These combined efforts are crucial for preventing tissue breakdown and promoting patient comfort.

Question 8: Why should gloves be worn during peri-care?

To stay warm
To prevent odor
To protect against infection (Correct answer)
To dry the area quickly

Correct answer: To protect against infection

Gloves must be worn during peri-care (perineal care) to protect both the patient and the CNA from the transmission of microorganisms. This procedure involves contact with bodily fluids, which can contain pathogens. Wearing gloves creates a barrier, preventing the spread of infection and maintaining proper hygiene and safety.

Question 9: Which of the following is a sign of infection?

Cool, dry skin
Redness and swelling (Correct answer)
Normal appetite
Clear urine

Correct answer: Redness and swelling

Redness and swelling are classic signs of inflammation, which often indicates an underlying infection. These symptoms occur as the body's immune system responds to pathogens, increasing blood flow and fluid accumulation in the affected area. CNAs should report these observations promptly to the nurse for further assessment and intervention.

Question 10: How should a CNA respond to a patient who refuses care?

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

Correct answer: Inform the nurse and respect the decision

Patients have the right to refuse medical treatment or care, even if it's deemed beneficial. If a patient refuses care, a CNA must respect their decision and immediately inform the nurse. The nurse can then assess the situation, understand the patient's reasons, and explore alternative approaches or educate the patient further, ensuring their autonomy is upheld.

Question 11: What is the normal range for adult blood pressure?

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

Correct answer: 120/80 mmHg

A blood pressure reading of 120/80 mmHg is generally considered the normal range for an adult. The top number (systolic) represents the pressure when the heart beats, and the bottom number (diastolic) is the pressure when the heart rests between beats. Maintaining blood pressure within this range is crucial for cardiovascular health and preventing complications.

Question 12: Which of the following tasks is appropriate for a CNA?

Diagnosing illness
Administering IV medications
Assisting with bathing (Correct answer)
Prescribing treatments

Correct answer: Assisting with bathing

Assisting with activities of daily living (ADLs) such as bathing is a primary and appropriate task for a Certified Nursing Assistant (CNA). CNAs provide direct patient care under the supervision of a licensed nurse, focusing on comfort, hygiene, and mobility. Diagnosing, administering IV medications, or prescribing treatments are outside the CNA's scope of practice.

Question 13: What should be done before feeding a patient?

Ask if they are hungry
Offer a drink of water
Position them upright (Correct answer)
Measure their weight

Correct answer: Position them upright

Before feeding a patient, it is crucial to position them upright, ideally at a 90-degree angle, or as close as their condition allows. This position helps prevent aspiration, where food or liquid enters the lungs instead of the stomach, which can lead to pneumonia. Proper positioning ensures safer swallowing and digestion, reducing the risk of complications.

Question 14: When should a CNA report a patient's condition to the nurse?

Only during emergencies
At the end of the shift
Whenever there is a change in condition (Correct answer)
Never

Correct answer: Whenever there is a change in condition

A CNA must report any change in a patient's condition to the nurse immediately, not just during emergencies or at the end of a shift. Early detection of changes, whether subtle or significant, allows the nursing team to assess, intervene, and prevent potential complications. This proactive communication is essential for patient safety and effective care.
