CERTIFIED WOUND CARE NURSE (CWCN®)
WOCNCB CERTIFICATION GUIDE QUESTIONS AND 100%
VERIFIED ANSWERS WITH RATIONALES GRADED A+
GUARANTEED PASS ON THE FIRST ATTEMPT
1. A 76-year-old immobile patient has non-blanchable erythema over the sacrum
with intact skin. Which classification is most appropriate?
A. Stage 2 pressure injury
B. Stage 1 pressure injury
C. Deep tissue pressure injury
D. Moisture-associated skin damage
Correct Answer: B
Rationale: Stage 1 pressure injury presents as non-blanchable erythema of intact
skin, often over a bony prominence. There is no skin loss.
2. Which finding most strongly suggests an arterial ulcer rather than a venous
ulcer?
A. Heavy exudate
B. Irregular wound margins
C. Pain that worsens with elevation
D. Location over the medial malleolus
Correct Answer: C
Rationale: Arterial ulcers are typically painful and worsen with elevation due to
reduced perfusion. Venous ulcers often improve with elevation.
,3. A wound is in the inflammatory phase of healing. Which process is expected
during this phase?
A. Collagen remodeling
B. Angiogenesis
C. Hemostasis and clot formation
D. Phagocytosis of bacteria and debris
Correct Answer: D
Rationale: The inflammatory phase involves immune response, including
phagocytosis to remove bacteria and necrotic tissue.
4. Which nutritional deficiency most directly impairs collagen synthesis?
A. Vitamin A
B. Vitamin C
C. Vitamin K
D. Zinc
Correct Answer: B
Rationale: Vitamin C is essential for collagen formation. Deficiency leads to
delayed wound healing.
5. A diabetic patient presents with a plantar foot ulcer surrounded by callus and
minimal pain. What is the most likely etiology?
A. Venous insufficiency
B. Pressure injury
C. Neuropathic ulcer
D. Vasculitic ulcer
Correct Answer: C
Rationale: Neuropathic ulcers are common in diabetes, often painless, and
surrounded by callus due to loss of protective sensation.
,6. Which dressing is most appropriate for a heavily exudative wound?
A. Hydrocolloid
B. Transparent film
C. Alginate
D. Dry gauze
Correct Answer: C
Rationale: Alginates absorb large amounts of exudate and are appropriate for
heavily draining wounds.
7. A wound with black, dry, stable eschar on the heel should be managed initially
by:
A. Sharp debridement
B. Enzymatic debridement
C. Leaving it intact and monitoring
D. Wet-to-dry dressings
Correct Answer: C
Rationale: Stable, dry eschar on the heel without signs of infection should not be
debrided.
8. Which factor most significantly delays wound healing in older adults?
A. Increased inflammatory response
B. Reduced collagen deposition
C. Increased angiogenesis
D. Higher metabolic rate
Correct Answer: B
Rationale: Aging is associated with decreased collagen synthesis and tensile
strength.
, 9. Which sign is most indicative of localized wound infection?
A. Pale wound bed
B. Increased granulation tissue
C. Purulent drainage
D. Epithelialization
Correct Answer: C
Rationale: Purulent drainage is a classic sign of localized infection.
10. Compression therapy is contraindicated when the ankle-brachial index (ABI)
is:
A. 1.1
B. 0.9
C. 0.7
D. 1.0
Correct Answer: C
Rationale: ABI below 0.8 indicates arterial insufficiency, making compression
unsafe.
11. Which intervention best supports prevention of pressure injuries in a high-risk
patient?
A. Massage over bony prominences
B. Repositioning every 2 hours
C. Use of donut cushions
D. Daily antiseptic skin cleansing
Correct Answer: B
Rationale: Regular repositioning reduces pressure duration and is evidence-based
prevention.
