Answer to Question 1

epidermis
The epidermis, or outer skin layer, is the first line of defense against external injury and infection. It contains several thin layers of cells undergoing different stages of maturation.

Answer to Question 2

B
To promote patient comfort, administer an analgesic as ordered, usually 30 to 45 minutes before changing the dressing. However, you will need to assess to determine the best time for analgesic administration before providing wound care. Do not remove an initial surgical dressing for direct wound inspection until a physician writes a medical order for removal. The presence of wound exudate is an expected stage of epithelial cell growth.
