Which concentration of normal saline is recommended for wound irrigation per WOCN and AHRQ guidelines?
Answer: 0.9% saline (normal saline)
0.9% normal saline is the recommended irrigation solution as it is isotonic, non-cytotoxic, and effective for wound cleansing.
Periwound maceration is MOST likely caused by which of the following?
Answer: Inadequate moisture balance with excessive exudate pooling on intact skin
Maceration occurs when excess wound exudate pools on intact periwound skin, breaking down skin integrity.
A wound care specialist selects larval (maggot) debridement therapy for a patient. What is a CONTRAINDICATION to this therapy?
Answer: Wounds communicating with body cavities or organs
Larval debridement is contraindicated in wounds with fistulae or communication with body cavities due to risk of larvae migration.
Which statement about hypochlorous acid (HOCl) solutions used in wound bed preparation is MOST accurate?
Answer: HOCl at appropriate concentrations is bactericidal and biocompatible with healing tissue
Electrolyzed HOCl solutions are effective antimicrobials that are biocompatible at appropriate concentrations, making them suitable for chronic wound management.
When assessing wound bed tissue types, which color is associated with non-viable, dry necrotic tissue (eschar)?
Answer: Black
Black or dark brown eschar represents dry, desiccated necrotic tissue that must be debrided to allow wound healing.
A patient has a Stage 4 pressure injury with undermining and tunneling. How should wound measurements be documented for tunneling?
Answer: Measured using a cotton-tipped applicator and clock-face orientation in centimeters
Tunneling is measured by inserting a cotton-tipped applicator to its deepest point and documenting length with clock-face orientation for direction.
Excess matrix metalloproteinases (MMPs) in a chronic wound primarily impair healing by:
Answer: Degrading growth factors and extracellular matrix components needed for repair
Elevated MMPs in chronic wounds destroy growth factors, fibronectin, and extracellular matrix proteins essential for tissue repair.
