Answer to Question 1

Ans: D
The dermal vascular bed decreases by about one-third with increased age; this contributes to the atrophy and fibrosis of hair bulbs and sweat and sebaceous glands. However, sweat glands do not wholly stop functioning. Collagen tends to thin rather than thicken, and the number of melanocytes in the epidermis decreases.

Answer to Question 2

Ans: A, C, D
A muted pain response, increased healing time, and decreased resistance to shearing all contribute to older adults' susceptibility to injury. Changes in vitamin D may occur with age, but these changes do not constitute a risk for injury. Similarly, changes in pigmentation are not a significant risk factor for injury.
