Wound Care Certification Exam Wound Care Certification Wound Bed Preparation Techniques 5 — Questions and Answers
Question 1: A patient requires wound bed preparation before split-thickness skin grafting. Which wound bed characteristic is MOST predictive of graft success?
- Presence of at least 30% granulation tissue
- Clean, well-vascularized granulation tissue covering >95% of the wound bed (Correct answer)
- Wound culture negative for all organisms
- Wound depth less than 2 cm
Correct answer: Clean, well-vascularized granulation tissue covering >95% of the wound bed
Successful graft take requires a well-vascularized, clean granulation tissue bed covering nearly the entire wound surface.
Question 2: Which of the following BEST describes the concept of 'wound bed preparation 2.0' as it has evolved beyond the original TIME framework?
- Focus solely on debridement frequency
- Addition of host factors including patient-centered concerns, biofilm management, and advanced therapies (Correct answer)
- Replacement of moist wound healing with dry wound healing
- Elimination of the use of antimicrobial dressings
Correct answer: Addition of host factors including patient-centered concerns, biofilm management, and advanced therapies
Wound Bed Preparation 2.0 expanded TIME to include patient-centered care, biofilm as a primary barrier, and integration of advanced therapies.
Question 3: A clinician documents 'epibole' during wound assessment. What does this term describe?
- Granulation tissue that rises above the wound surface
- Rolled, thickened wound edges where epithelium has turned down into the wound (Correct answer)
- Fibrinous slough in the wound bed
- Periwound edema
Correct answer: Rolled, thickened wound edges where epithelium has turned down into the wound
Epibole refers to rolled or curled wound edges where epithelial cells have migrated down into the wound rather than across it.
Question 4: Which topical agent is MOST appropriate to apply to hypergranulation tissue to reduce it and allow re-epithelialization?
- Hydrogel
- Silver nitrate or foam dressing with compression (Correct answer)
- Collagenase ointment
- Zinc oxide paste
Correct answer: Silver nitrate or foam dressing with compression
Silver nitrate sticks chemically cauterize hypergranulation tissue, and compressive foam dressings reduce it mechanically to allow epithelial migration.
Question 5: When evaluating wound exudate as part of wound bed preparation, which exudate characteristic suggests wound infection rather than normal healing?
- Clear to straw-colored serous exudate
- Thin, blood-tinged serosanguineous exudate
- Cloudy, malodorous, purulent exudate (Correct answer)
- Moderate serous exudate after dressing change
Correct answer: Cloudy, malodorous, purulent exudate
Purulent, malodorous, cloudy exudate is a hallmark of wound infection requiring bioburden reduction strategies.
Question 6: A wound care nurse is choosing between conservative sharp debridement and surgical debridement. Which criterion MOST strongly indicates the need for surgical debridement?
- Small amount of surface slough in a shallow wound
- Large, deep wound with extensive necrosis and signs of spreading infection (Correct answer)
- Patient preference for faster healing
- Wound located on the lower extremity
Correct answer: Large, deep wound with extensive necrosis and signs of spreading infection
Surgical debridement is indicated when there is extensive necrosis with spreading infection that conservative methods cannot adequately or rapidly address.
Question 7: In wound bed preparation, which factor is MOST responsible for converting a chronic wound environment to an acute wound environment?
- Increasing the frequency of dressing changes
- Effective debridement that removes senescent cells and reduces bioburden (Correct answer)
- Applying growth factor therapy without debridement
- Increasing systemic nutritional support alone
Correct answer: Effective debridement that removes senescent cells and reduces bioburden
Effective debridement removes senescent cells, reduces bioburden, and resets the wound biochemistry toward an acute, healing-responsive state.
