CNA Wound Care and Skin Integrity 3 — Questions and Answers
Question 1: A resident has a pressure injury with black, hard, leathery tissue covering it. This tissue is called:
- Slough
- Granulation tissue
- Eschar (Correct answer)
- Fibrin
Correct answer: Eschar
Eschar is black, brown, or tan hardened dead tissue (necrotic tissue) that can obscure the true wound depth.
Question 2: Which nutritional element is MOST important for wound healing?
- Calcium
- Protein (Correct answer)
- Vitamin D
- Iron
Correct answer: Protein
Protein is essential for tissue repair, immune function, and collagen synthesis needed for wound healing.
Question 3: A CNA observes that a resident's wound has increased redness, warmth, and swelling around it. These signs indicate:
- Normal wound healing
- Signs of wound infection requiring nurse notification (Correct answer)
- Allergic reaction to the dressing material
- Successful granulation tissue formation
Correct answer: Signs of wound infection requiring nurse notification
Increased redness, warmth, and swelling are classic signs of infection (calor, rubor, tumor) and must be reported to the nurse immediately.
Question 4: Which type of drainage from a wound is considered abnormal and must be reported immediately?
- Serous drainage (clear, watery)
- Sanguineous drainage (bright red) (Correct answer)
- Serosanguineous drainage (pink-tinged)
- All wound drainage is normal
Correct answer: Sanguineous drainage (bright red)
Sanguineous drainage indicates active bleeding, which requires prompt nursing assessment and intervention.
Question 5: To prevent friction injuries when moving a resident up in bed, the CNA should:
- Move the resident quickly to reduce skin contact time
- Use a lift sheet or draw sheet to slide the resident (Correct answer)
- Leave the head of bed elevated at 45 degrees
- Rub the resident's skin with lotion before moving
Correct answer: Use a lift sheet or draw sheet to slide the resident
A lift or draw sheet reduces friction by allowing the resident to be lifted rather than dragged across the bed surface.
Question 6: A resident with diabetes has a wound on their foot. Why does the CNA need to monitor this wound more carefully?
- Diabetes causes faster wound healing requiring more frequent dressing changes
- Diabetes impairs circulation and nerve sensation, slowing healing and masking pain (Correct answer)
- Diabetic patients are more likely to pull off their dressings
- Diabetes has no specific effect on wound healing
Correct answer: Diabetes impairs circulation and nerve sensation, slowing healing and masking pain
Diabetes compromises circulation and causes neuropathy, so wounds heal more slowly and residents may not feel pain indicating worsening.
Question 7: Which action best protects the heels of a bedridden resident from pressure injuries?
- Apply lotion to the heels daily
- Keep sheets tucked tightly over the feet
- Use heel protector boots or elevate heels off the mattress (Correct answer)
- Place a rolled towel under the calves
Correct answer: Use heel protector boots or elevate heels off the mattress
Heel protector boots or elevating the heels completely off the mattress eliminate pressure on this vulnerable bony prominence.
