CWS Wound Care 2 — Questions and Answers
Question 1: Which wound bed tissue type appears as yellow, stringy, and moist and indicates the presence of devitalized tissue?
- Granulation tissue
- Slough (Correct answer)
- Eschar
- Epithelial tissue
Correct answer: Slough
Slough is devitalized tissue that appears yellow, tan, or green and stringy or mucinous, requiring debridement to promote healing.
Question 2: A patient with a stage 3 pressure injury has a wound measuring 4 cm × 3 cm × 1.5 cm deep with moderate exudate. Which dressing is MOST appropriate?
- Dry gauze dressing
- Alginate dressing (Correct answer)
- Transparent film dressing
- Hydrocolloid wafer
Correct answer: Alginate dressing
Alginate dressings are highly absorbent and ideal for moderate-to-heavy exudate wounds with depth, forming a gel that maintains moisture balance.
Question 3: What is the primary goal of the TIME framework in wound bed preparation?
- Selecting antibiotic therapy
- Addressing barriers to wound healing systematically (Correct answer)
- Calculating wound surface area
- Staging pressure injuries
Correct answer: Addressing barriers to wound healing systematically
TIME (Tissue, Infection/Inflammation, Moisture, Edge) is a framework to identify and address wound healing barriers systematically.
Question 4: Which type of debridement is MOST selective and removes only necrotic tissue while preserving healthy tissue?
- Wet-to-dry gauze
- Sharp surgical debridement
- Enzymatic debridement (Correct answer)
- Pulsed lavage
Correct answer: Enzymatic debridement
Enzymatic debridement uses chemical agents like collagenase to selectively break down necrotic tissue without damaging viable tissue.
Question 5: A patient presents with a venous leg ulcer. Which ankle-brachial index (ABI) range indicates safe application of full compression therapy?
- ABI < 0.5
- ABI 0.5–0.79
- ABI 0.8–1.2 (Correct answer)
- ABI > 1.3
Correct answer: ABI 0.8–1.2
An ABI of 0.8–1.2 indicates adequate arterial flow, making full compression therapy safe for venous ulcer management.
Question 6: Which factor is the MOST critical in determining wound healing potential in a patient with diabetes?
- Patient's age
- Glycemic control (HbA1c) (Correct answer)
- Body mass index
- Wound location
Correct answer: Glycemic control (HbA1c)
Elevated HbA1c reflects poor long-term glycemic control, which impairs immune function, collagen synthesis, and microvascular perfusion critical to wound healing.
Question 7: In negative pressure wound therapy (NPWT), what is the standard continuous pressure setting used for most wounds?
- -50 mmHg
- -75 mmHg
- -125 mmHg (Correct answer)
- -200 mmHg
Correct answer: -125 mmHg
The standard continuous pressure for NPWT is -125 mmHg, which promotes granulation, reduces edema, and draws wound edges together.
