CWS Certified Wound Specialist MCQ 3 — Questions and Answers
Question 1: Which dressing is MOST appropriate for a heavily exudating wound with fragile periwound skin?
- Superabsorbent polymer dressing (Correct answer)
- Transparent film dressing
- Hydrocolloid dressing
- Hydrogel sheet
Correct answer: Superabsorbent polymer dressing
Superabsorbent polymer dressings handle heavy exudate while preventing periwound maceration that would worsen fragile skin.
Question 2: The primary mechanism by which negative pressure wound therapy (NPWT) promotes wound healing is:
- Mechanical stretch promoting cell proliferation and increased perfusion (Correct answer)
- Desiccation of wound tissue to reduce bacterial load
- Debridement of necrotic tissue via suction
- Delivery of antimicrobial agents to wound bed
Correct answer: Mechanical stretch promoting cell proliferation and increased perfusion
NPWT applies mechanical stretch forces that stimulate cell proliferation, granulation tissue formation, and increase local blood flow.
Question 3: A diabetic foot ulcer is classified as University of Texas Grade 2B. What does this indicate?
- Deep wound to tendon or capsule with ischemia (Correct answer)
- Superficial wound without infection or ischemia
- Deep wound with osteomyelitis
- Wound penetrating to bone with infection and ischemia
Correct answer: Deep wound to tendon or capsule with ischemia
UT Grade 2 = wound penetrating to tendon or capsule; Stage B = ischemia present; together 2B indicates deep wound to tendon/capsule with ischemia.
Question 4: Which debridement method is CONTRAINDICATED in a wound with exposed blood vessels or organs?
- Mechanical wet-to-dry debridement (Correct answer)
- Enzymatic debridement
- Autolytic debridement
- Maggot debridement therapy
Correct answer: Mechanical wet-to-dry debridement
Wet-to-dry mechanical debridement is indiscriminate and can traumatize or disrupt exposed vessels or organs upon removal.
Question 5: A patient with a Stage 4 sacral pressure injury has tunneling at 3 o'clock measuring 4 cm. How should this be documented?
- Tunneling at 3 o'clock, 4 cm depth (Correct answer)
- Undermining at 3 o'clock, 4 cm
- Sinus tract, 4 cm, anterior direction
- Fistula measuring 4 cm at lateral border
Correct answer: Tunneling at 3 o'clock, 4 cm depth
Tunneling is documented by its clock position and depth in centimeters; 3 o'clock is the correct directional notation with a probe-measured depth.
Question 6: Which organism is the MOST common cause of osteomyelitis complicating a diabetic foot ulcer?
- Staphylococcus aureus (Correct answer)
- Pseudomonas aeruginosa
- Bacteroides fragilis
- Streptococcus pyogenes
Correct answer: Staphylococcus aureus
Staphylococcus aureus is the predominant pathogen in diabetic foot osteomyelitis, though polymicrobial infections are also common in chronic wounds.
Question 7: Periwound skin that appears dark purple, boggy, and non-blanchable in a patient on a pressure relief surface MOST likely represents:
- Deep tissue pressure injury (DTPI) (Correct answer)
- Unstageable pressure injury
- Stage 2 pressure injury
- Moisture-associated skin damage (MASD)
Correct answer: Deep tissue pressure injury (DTPI)
Dark purple, non-blanchable, boggy periwound tissue is the hallmark of deep tissue pressure injury caused by internal tissue damage from sustained pressure.
