Wound Care Certification Exam Wound Care Certification Wound Bed Preparation Techniques 2 — Questions and Answers
Question 1: Which component of the TIME framework specifically addresses the moisture balance in the wound environment?
- T – Tissue management
- I – Infection/inflammation control
- M – Moisture balance (Correct answer)
- E – Edge of wound
Correct answer: M – Moisture balance
The 'M' in TIME stands for Moisture balance, targeting excess exudate or desiccation that impairs healing.
Question 2: A wound with hyperkeratotic edges fails to advance despite good wound bed preparation. What is the MOST appropriate next intervention?
- Apply a hydrocolloid dressing
- Debride the wound edges mechanically or chemically (Correct answer)
- Increase frequency of dressing changes
- Start systemic antibiotics
Correct answer: Debride the wound edges mechanically or chemically
Hyperkeratotic or rolled wound edges must be debrided to stimulate edge epithelial cell migration and wound closure.
Question 3: When using the moist wound healing principle, which dressing is MOST appropriate for a dry, necrotic wound to facilitate autolytic debridement?
- Alginate dressing
- Foam dressing
- Hydrogel dressing (Correct answer)
- Antimicrobial gauze
Correct answer: Hydrogel dressing
Hydrogel dressings donate moisture to dry necrotic tissue, promoting autolytic debridement.
Question 4: A patient's wound has critical colonization. Which clinical sign BEST distinguishes this from frank infection?
- Periwound erythema >2 cm
- Systemic fever and leukocytosis
- Stalled healing with increased exudate but no systemic signs (Correct answer)
- Wound cultures positive for Staphylococcus aureus
Correct answer: Stalled healing with increased exudate but no systemic signs
Critical colonization presents with stalled healing and increased exudate without systemic inflammatory response, unlike frank infection.
Question 5: Which type of debridement is CONTRAINDICATED in a patient on warfarin therapy with a vascular wound?
- Autolytic debridement
- Enzymatic debridement
- Sharp/surgical debridement (Correct answer)
- Biological (maggot) debridement
Correct answer: Sharp/surgical debridement
Sharp debridement carries high bleeding risk in anticoagulated patients and is contraindicated unless in a controlled surgical setting.
Question 6: In wound bed preparation, biofilm management is critical. Which intervention is MOST effective at disrupting mature wound biofilm?
- Topical antiseptics alone
- Systemic antibiotics alone
- Mechanical debridement combined with antimicrobial dressings (Correct answer)
- Occlusive dressings
Correct answer: Mechanical debridement combined with antimicrobial dressings
Mature biofilm requires physical disruption through mechanical debridement followed by antimicrobial therapy to prevent rapid reformation.
Question 7: A wound clinician uses negative pressure wound therapy (NPWT) as part of wound bed preparation. What is the PRIMARY mechanism by which NPWT prepares the wound bed?
- It delivers oxygen directly to the wound tissue
- It removes excess exudate and promotes granulation tissue formation (Correct answer)
- It sterilizes the wound by creating anaerobic conditions
- It replaces the need for debridement
Correct answer: It removes excess exudate and promotes granulation tissue formation
NPWT removes excess exudate, reduces edema, and promotes granulation tissue formation, creating a favorable wound bed for healing or grafting.
