Question 1
A patient presents with a stage 3 pressure injury. Which layer is primarily
affected?
A. Epidermis only
B. Dermis only
C. Full-thickness skin loss involving subcutaneous tissue
D. Muscle and bone exposure
Correct Answer: C
Rationale: A stage 3 pressure injury involves full-thickness skin loss extending
into subcutaneous tissue but not exposing muscle or bone. The epidermis and
dermis are fully destroyed, and adipose tissue may be visible. It differs from
stage 4, which includes exposure of deeper structures such as muscle, tendon, or
bone.
Question 2
Which factor most directly impairs collagen synthesis in wound healing?
A. Vitamin C deficiency
B. Increased oxygen tension
,C. Excessive hydration
D. Low body temperature
Correct Answer: B
Rationale: Vitamin C is essential for hydroxylation of proline and lysine in
collagen synthesis; its deficiency impairs wound healing. Adequate oxygen
tension is also necessary, but increased oxygen generally supports collagen
formation. The other options do not directly affect collagen synthesis.
Question 3
Which dressing is most appropriate for a heavily exudating wound?
A. Hydrocolloid
B. Alginate
C. Transparent film
D. Dry gauze only
Correct Answer: B
Rationale: Alginate dressings are highly absorbent and ideal for moderate to
heavily exudating wounds. Hydrocolloids are for low to moderate exudate,
transparent films are for superficial wounds, and dry gauze lacks moisture
management capacity.
Question 4
What is the primary purpose of debridement in wound care?
A. Increase bacterial colonization
B. Remove nonviable tissue and promote healing
C. Decrease oxygen delivery
D. Seal the wound from external environment
Correct Answer: D
,Rationale: Debridement removes necrotic tissue, reducing bacterial load and
promoting granulation tissue formation. It enhances healing by improving
perfusion and allowing healthy tissue regeneration.
Question 5
Which condition most increases risk for arterial ulcers?
A. Venous insufficiency
B. Peripheral arterial disease
C. Lymphedema
D. Hypertension only
Correct Answer: B
Rationale: Peripheral arterial disease reduces blood flow to distal tissues,
leading to ischemia and arterial ulcers, typically on toes or pressure points.
Venous insufficiency causes venous ulcers, not arterial.
Question 6
Which sign is most consistent with infection in a chronic wound?
A. Pale wound bed
B. Increased granulation tissue
C. Erythema, warmth, and purulent drainage
D. Decreased exudate only
Correct Answer: C
Rationale: Classic signs of infection include erythema, warmth, swelling, pain,
and purulent drainage. Chronic wounds may show subtle infection signs, but
purulence strongly indicates bacterial burden.
Question 7
, Negative pressure wound therapy (NPWT) primarily works by:
A. Increasing desiccation
B. Enhancing perfusion and removing exudate
C. Sealing wound completely from oxygen
D. Destroying fibroblasts
Correct Answer: B
Rationale: NPWT improves wound healing by reducing edema, increasing local
perfusion, promoting granulation tissue formation, and removing exudate and
infectious material.
Question 8
Which wound stage involves intact skin with non-blanchable redness?
A. Stage 1
B. Stage 2
C. Stage 3
D. Stage 4
Correct Answer: A
Rationale: Stage 1 pressure injuries present as intact skin with non-blanchable
erythema, indicating early tissue ischemia without skin breakdown.
Question 9
Which systemic factor most delays wound healing?
A. Adequate protein intake
B. Diabetes mellitus
C. Mild hydration
D. Normal BMI
Correct Answer: B
