CNA Basic Nursing Skills 17 3 — Questions and Answers
Question 1: A resident has a stage 2 pressure injury on their coccyx. Which position change schedule should the CNA follow?
- Reposition every 4 hours
- Reposition every 2 hours (Correct answer)
- Reposition only when the resident requests it
- Reposition once per shift
Correct answer: Reposition every 2 hours
Residents at risk for or with pressure injuries should be repositioned at least every 2 hours to relieve pressure and promote circulation.
Question 2: When performing passive range-of-motion exercises, the CNA should stop if the resident:
- Asks to rest for a moment
- Reports mild stiffness at the start
- Experiences pain or resistance during the movement (Correct answer)
- Has not exercised in several days
Correct answer: Experiences pain or resistance during the movement
Pain or resistance during ROM exercises indicates potential injury risk, and the CNA should stop and report to the nurse.
Question 3: A resident's urine output is 250 mL over 8 hours. The CNA should:
- Encourage the resident to drink more fluids and document normally
- Record the output and report it to the nurse as low (Correct answer)
- Catheterize the resident immediately
- Withhold fluids to concentrate the urine
Correct answer: Record the output and report it to the nurse as low
Normal urine output is approximately 30 mL/hour; 250 mL in 8 hours falls below this threshold and must be reported promptly.
Question 4: Which action by the CNA correctly demonstrates proper body mechanics when lifting a heavy object from the floor?
- Bend at the waist and keep legs straight
- Squat using leg muscles, keeping the back straight (Correct answer)
- Twist the torso to shift weight to one side
- Hold the object away from the body to gain leverage
Correct answer: Squat using leg muscles, keeping the back straight
Squatting with bent knees and a straight back uses the stronger leg muscles and protects the spine from injury.
Question 5: While assisting a resident with oral care, the CNA notices the resident has loose dentures that do not fit properly. The priority action is to:
- Apply denture adhesive and continue care
- Document the finding and report it to the nurse (Correct answer)
- Remove the dentures and store them permanently
- Ask the resident's family to purchase new dentures
Correct answer: Document the finding and report it to the nurse
Ill-fitting dentures can cause sores, choking, or aspiration risk and must be documented and reported to the nurse for follow-up.
Question 6: A resident receiving oxygen via nasal cannula has a flow rate of 4 L/min. The CNA notices the humidifier bottle is empty. The correct action is to:
- Increase the flow rate to compensate for the dryness
- Refill the humidifier with sterile or distilled water and report to the nurse (Correct answer)
- Remove the nasal cannula until the nurse arrives
- Fill the humidifier with tap water immediately
Correct answer: Refill the humidifier with sterile or distilled water and report to the nurse
Humidifier bottles should be refilled with sterile or distilled water (per facility policy) and the nurse notified, since dry oxygen can irritate mucous membranes.
Question 7: The CNA is preparing to give a resident a bed bath. Which water temperature is safest?
- 110–115°F (43–46°C)
- 105–110°F (40–43°C) (Correct answer)
- 115–120°F (46–49°C)
- 90–95°F (32–35°C)
Correct answer: 105–110°F (40–43°C)
Water between 105–110°F (40–43°C) is warm enough for comfort while minimizing burn risk, especially for residents with reduced sensation.
