Black polyurethane foam dressing has a property that helps determine wound depth. Which statement describes that property?

• A. Contracts the wound
• B. Absorbs fluids from the wound
• C. Restricts growth of granulation tissue
• D. Helps determine depth of the wound

Answer: (D)

The main idea here is that some foam dressings can double as a quick, qualitative gauge of wound depth. The black polyurethane foam is designed to conform to the wound bed and fill cavities as it absorbs exudate. When you remove the dressing, how far the foam has penetrated into the wound indicates how deep the wound is. In other words, the dressing provides a visual cue to help estimate depth. While absorbing fluids is a useful property, it doesn’t by itself reveal depth; contracting the wound or restricting granulation tissue aren’t properties of this dressing. The statement that it helps determine the depth of the wound best describes its depth-assessment role.
