1. A patient with a Stage 2 pressure injury presents with partial-thickness skin
loss. Which dressing is most appropriate initially?
A. Dry gauze
B. Hydrocolloid
C. Alginate
D. Negative pressure wound therapy
Answer: B
Rationale: Hydrocolloid dressings maintain a moist environment and
protect partial-thickness wounds, promoting epithelialization.
2. Which factor most significantly impairs wound healing?
A. Adequate protein intake
B. Normothermia
C. Poor perfusion
D. Controlled blood glucose
Answer: C
Rationale: Adequate perfusion is essential for oxygen and nutrient
delivery; impaired blood flow delays all phases of wound healing.
3. Which wound characteristic is typical of venous leg ulcers?
A. Punched-out edges
B. Located on pressure points
, C. Irregular borders with heavy exudate
D. Dry, necrotic tissue
Answer: C
Rationale: Venous ulcers often have irregular edges, are highly exudative,
and occur in the gaiter area of the lower leg.
4. The most reliable indicator of adequate arterial blood flow before
compression therapy is:
A. Capillary refill
B. Skin temperature
C. Ankle-brachial index (ABI)
D. Presence of edema
Answer: C
Rationale: ABI objectively measures arterial perfusion and guides safe use
of compression therapy.
5. Which nutrient deficiency most directly affects collagen synthesis?
A. Vitamin A
B. Vitamin C
C. Vitamin K
D. Zinc
Answer: B
Rationale: Vitamin C is essential for collagen formation and tensile
strength of healing tissue.
6. A wound with black, dry eschar on the heel and no signs of infection should
be managed by:
A. Sharp debridement
B. Enzymatic debridement
C. Leaving it intact
D. Wet-to-dry dressings
Answer: C
Rationale: Stable, dry heel eschar without infection should remain intact
to serve as a natural biologic cover.
, 7. Which type of debridement is most selective?
A. Autolytic
B. Mechanical
C. Sharp surgical
D. Biological
Answer: D
Rationale: Maggot (biological) therapy selectively consumes necrotic
tissue while sparing healthy tissue.
8. What is the primary goal of wound bed preparation?
A. Reduce pain
B. Achieve hemostasis
C. Optimize the wound environment
D. Eliminate all bacteria
Answer: C
Rationale: Wound bed preparation focuses on optimizing conditions to
support healing, including moisture balance and tissue quality.
9. Which microorganism load typically defines wound infection?
A. Any bacterial presence
B. >10² organisms/g tissue
C. >10⁵ organisms/g tissue
D. Only anaerobic bacteria
Answer: C
Rationale: A bacterial burden greater than 10⁵ organisms per gram of
tissue is commonly associated with infection.
10.Which pressure injury stage involves full-thickness skin loss with exposed
bone or tendon?
A. Stage 2
B. Stage 3
C. Stage 4
D. Unstageable
Answer: C
