Answer to Question 1

ANS: A, B, C, E
Emollients keep the skin moist and reduce dryness. All other options listed contribute to pruritus.

Answer to Question 2

ANS: A, B, C, E
The hydrocolloid dressing prevents shear force trauma to the ulcer while granulation tissue and reepithelialization are occurring during healing. It also forms an air-occlusive seal, protects the ulcer from infection, and absorbs exudate. If there were eschar present, it would soften it.
