Wound Care Certification Exam Wound Care Certification Knowledge 3 — Questions and Answers
Question 1: Which ankle-brachial index (ABI) value indicates severe peripheral arterial disease contraindicating compression therapy?
- 0.9–1.1
- 0.7–0.89
- 0.5–0.69
- Less than 0.5 (Correct answer)
Correct answer: Less than 0.5
An ABI below 0.5 indicates severe PAD, and compression therapy is contraindicated due to risk of further ischemia.
Question 2: What is the primary goal of negative pressure wound therapy (NPWT)?
- Eliminate biofilm
- Promote angiogenesis and reduce edema (Correct answer)
- Deliver antibiotics locally
- Maintain moist wound environment
Correct answer: Promote angiogenesis and reduce edema
NPWT applies subatmospheric pressure to promote granulation tissue formation, angiogenesis, and reduction of wound edema.
Question 3: A diabetic foot ulcer classified as Wagner Grade 3 is characterized by:
- Superficial ulcer without subcutaneous involvement
- Deep ulcer with tendon or joint capsule involvement
- Deep ulcer with osteomyelitis or abscess (Correct answer)
- Gangrene of the forefoot
Correct answer: Deep ulcer with osteomyelitis or abscess
Wagner Grade 3 denotes a deep ulcer complicated by osteomyelitis, abscess, or joint infection.
Question 4: Which organism is most commonly associated with necrotizing fasciitis requiring emergent surgical debridement?
- Staphylococcus aureus
- Group A Streptococcus (Streptococcus pyogenes) (Correct answer)
- Pseudomonas aeruginosa
- Candida albicans
Correct answer: Group A Streptococcus (Streptococcus pyogenes)
Group A Streptococcus is the most frequent causative organism in monomicrobial necrotizing fasciitis.
Question 5: Which wound measurement technique provides the most accurate volume assessment for deep wounds?
- Length × width × depth formula
- Saline instillation (Correct answer)
- Acetate tracing
- Photography
Correct answer: Saline instillation
Saline instillation (filling the wound cavity with measurable saline) provides the most accurate volume for irregular deep wounds.
Question 6: Hyperbaric oxygen therapy (HBOT) is most indicated for which wound condition?
- Stage II pressure injury
- Venous leg ulcer with adequate compression
- Wagner Grade 3–4 diabetic foot ulcer (Correct answer)
- Surgical incision with delayed closure
Correct answer: Wagner Grade 3–4 diabetic foot ulcer
HBOT is evidence-based and indicated for Wagner Grade 3–4 diabetic foot ulcers with inadequate perfusion.
Question 7: The Braden Scale assesses risk for pressure injury development across six subscales; the lowest possible total score indicating maximum risk is:
- 6 (Correct answer)
- 9
- 12
- 23
Correct answer: 6
The Braden Scale ranges from 6 (highest risk) to 23 (lowest risk), with each subscale scored 1–4 (or 1–3 for some).
