CWS Certified Wound Specialist 3 — Questions and Answers
Question 1: Which clinical finding best distinguishes a venous leg ulcer from an arterial ulcer?
- Location at the medial malleolus with surrounding lipodermatosclerosis (Correct answer)
- Deep punched-out appearance with pale wound bed
- Severe rest pain relieved by dependency
- Absence of pedal pulses
Correct answer: Location at the medial malleolus with surrounding lipodermatosclerosis
Venous ulcers typically occur at the medial malleolus with surrounding lipodermatosclerosis and hemosiderin staining, unlike the punched-out appearance of arterial ulcers.
Question 2: Which component of the wound bed preparation concept does the 'M' in TIME represent?
- Moisture balance
- Moisture imbalance (Correct answer)
- Microbiological management
- Maceration control
Correct answer: Moisture imbalance
In the TIME framework, M stands for Moisture imbalance, addressing wounds that are too dry or too wet to heal optimally.
Question 3: A patient with diabetes has a plantar ulcer classified as Wagner Grade 3. What does this indicate?
- Superficial ulcer without infection
- Deep ulcer to tendon or capsule with infection
- Partial foot gangrene
- Full-thickness ulcer with abscess or osteomyelitis (Correct answer)
Correct answer: Full-thickness ulcer with abscess or osteomyelitis
Wagner Grade 3 indicates a deep ulcer with abscess, osteomyelitis, or joint sepsis, requiring aggressive medical and surgical management.
Question 4: Which debridement method is most selective and preserves healthy tissue while removing only necrotic tissue?
- Wet-to-dry mechanical debridement
- Sharp surgical debridement
- Enzymatic debridement with collagenase (Correct answer)
- High-pressure irrigation
Correct answer: Enzymatic debridement with collagenase
Enzymatic debridement with collagenase selectively digests necrotic collagen while sparing viable tissue, making it the most selective method.
Question 5: In the context of biofilm management, what is the primary reason topical antibiotics alone are insufficient?
- Antibiotics are too expensive for routine use
- Biofilm's extracellular polymeric substance matrix protects bacteria from antimicrobial penetration (Correct answer)
- Topical antibiotics cause excessive cytotoxicity to wound tissue
- Bacteria in biofilms are genetically resistant to all known antibiotics
Correct answer: Biofilm's extracellular polymeric substance matrix protects bacteria from antimicrobial penetration
The extracellular polymeric substance (EPS) matrix of biofilm acts as a physical and chemical barrier, preventing adequate antibiotic penetration to embedded bacteria.
Question 6: A patient's pressure injury presents as intact skin with non-blanchable erythema. This is classified as which stage?
- Suspected deep tissue injury
- Stage 1 (Correct answer)
- Stage 2
- Unstageable
Correct answer: Stage 1
Stage 1 pressure injuries are characterized by intact skin with localized non-blanchable erythema, typically over a bony prominence.
Question 7: Which nutritional marker is most commonly used to assess protein status in wound patients?
- Hemoglobin A1c
- Serum albumin (Correct answer)
- C-reactive protein
- Transferrin saturation
Correct answer: Serum albumin
Serum albumin, though affected by inflammation and hydration status, remains a widely used marker of protein status and nutritional risk in wound care.
