Which statement about three-layer dressings for heavy exudate wounds is NOT described?

• A. Inner non-adherent layer
• B. Absorbing intermediate layer
• C. Outer binding layer
• D. A non-structured random wrap

Answer: (D)

Heavy exudate dressings rely on a purposeful three-layer design to manage moisture and protect the wound. The inner layer is a non-adherent contact surface that won’t stick to the wound bed, the middle layer is highly absorbent to trap and hold exudate, and the outer layer acts as a protective binding layer to secure the dressing and provide a barrier. A non-structured random wrap doesn’t fit this defined system; it lacks a dedicated contact layer, a controlled absorbent layer, and a purpose-built outer barrier, so it isn’t described as part of the three-layer dressing concept.
