1. It allows the healthy tissue to regenerate.

ANS: 2
Removal of necrotic tissue is necessary to rid the ulcer of a source of infection, to enable visuali-zation of the wound bed, and to provide a clean base necessary for healthy tissue to regenerate. Autolytic debridement uses synthetic dressings over a wound to allow the eschar to be self-digested by the action of enzymes that are present in wound fluids. The wound is not irri-gated. Mechanical methods include wet-to-dry dressings, wound irrigation, and whirlpool treat-ments. Surgical debridement involves direct surgical removal of the eschar layer of the wound. Enzymatic debridement requires a health care provider's order.
