For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?
a. They contain exudate and provide a moist wound environment.
b. They protect the wound from mechanical trauma and promote healing.
c. They debride the wound and promote healing by secondary intention.
d. They prevent the entrance of microorganisms and minimize wound discomfort.

Answer C.
For this client, wet-to-dry dressings are most appropriate because they clean the foot ulcer by debriding exudate and necrotic tissue, thus promoting healing by secondary intention. Moist, transparent dressings contain exudate and provide a moist wound environment. Hydrocolloid dressings prevent the entrance of microorganisms and minimize wound discomfort. Dry sterile dressings protect the wound from mechanical trauma and promote healing.
