A dressing is prescribed to facilitate autolytic debridement. Which nursing action indicates effectiveness?

• A. Using sterile maggots to ingest the dead tissue
• B. Using scissors to remove the devitalized tissue
• C. Using Dakin's solution to break the necrotic tissue
• D. Using hydrocolloid dressings to remove the dead tissue

Answer: (D)

Autolytic debridement relies on keeping the wound moist so the body's own enzymes can soften and liquefy dead tissue. A hydrocolloid dressing creates and maintains a moist, occlusive environment that helps this process, softening necrotic tissue and allowing it to separate from the wound bed with gentle, nontraumatic dressing changes. It’s also nonadherent, reducing trauma when the tissue gradually comes away.

The other options don’t reflect autolysis: using maggots is biological debridement; using scissors is mechanical debridement; and using Dakin’s solution is chemical debridement that removes tissue through chemical means rather than letting the body’s enzymes do the work.
