Answer to Question 1

ANS: A, B, C, D
The primary cause of pressure ulcers is, as the name suggests, pressure. However, it is more than just pressure; it is the intensity of the pressure, the length of time that the tissue is subjected to the pressure, and intrinsic and extrinsic factors that affect the tissue's ability to withstand or tolerate that pressure. Intrinsic and extrinsic factors can include nutrition status and age.

Answer to Question 2

ANS: C
The subcutaneous layer delivers the blood supply to the dermis, provides insulation, and has a cushioning effect. The stratum germinativum constantly produces new cells that are pushed upward through the other layers of the epidermis toward the stratum corneum, where they flatten, die, and are eventually sloughed off and replaced by new cells. The epidermis is the outermost layer of the skin and the thinnest of the layers. The stratum corneum is made up of flattened dead cells.
