The nurse knows that mechanical debridement involves all of the following except:
a. wet to dry dressings.
b. whirlpool baths.
c. damp to dry dressing.
d. enzymatic dressing.
ANS: D
Enzymatic debridement is achieved through the application of topical agents containing enzymes that work by breaking down the fibrin, collagen, or elastin present in devitalized tissue, thus allowing for its removal. Mechanical debridement is a nonselective form of debridement because it not only removes the necrotic tissue, but also can remove or disturb exposed viable tissue that may be in the wound. The main forms of mechanical debridement are wet/damp-to-dry dressings and whirlpools.
