CERTIFIED WOUND CARE NURSE
(CWCN) ADVANCED EXAMINATION
1. A patient presents with a full-thickness wound where the base is completely obscured by
slough and eschar. How should this pressure injury be staged according to NPUAP guidelines?
A. Stage 3 Pressure Injury
B. Stage 4 Pressure Injury
C. Deep Tissue Pressure Injury
D. Unstageable Pressure Injury
Answer: D
Conceptual Explanation: A pressure injury is classified as Unstageable when the extent of
tissue damage (Stage 3 or 4) cannot be confirmed because it is obscured by slough or
eschar.
2. Which phase of wound healing is characterized by the peak activity of fibroblasts and the
synthesis of collagen?
A. Hemostasis Phase
B. Inflammatory Phase
,C. Maturation Phase
D. Proliferative Phase
Answer: D
Conceptual Explanation: The proliferative phase involves the formation of granulation
tissue, epithelialization, and collagen synthesis by fibroblasts.
3. An Ankle-Brachial Index (ABI) of 0.45 indicates which of the following conditions?
A. Severe peripheral artery disease
B. Mild peripheral artery disease
C. Moderate peripheral artery disease
D. Normal arterial flow
Answer: A
Conceptual Explanation: An ABI value less than 0.5 is indicative of severe arterial disease
and critical limb ischemia.
4. What is the primary goal of using a hydrogel dressing on a dry, necrotic wound?
A. To promote autolytic debridement by donating moisture
B. To absorb heavy exudate
C. To provide compression to the wound bed
D. To decrease bacterial load through silver ion release
, Answer: A
Conceptual Explanation: Hydrogels donate moisture to dry wounds, facilitating autolytic
debridement by softening necrotic tissue.
5. Which cellular component is responsible for wound contraction during the proliferative
phase?
A. Keratinocytes
B. Myofibroblasts
C. Macrophage
D. Neutrophils
Answer: B
Conceptual Explanation: Myofibroblasts contain actin filaments that contract, pulling the
wound edges together.
6. Which laboratory value is the most sensitive indicator of recent nutritional status in a
patient with a chronic wound?
A. Serum Albumin
B. Hemoglobin A1c
C. Total Protein
D. Serum Prealbumin
Answer: D
