A gerontological nurse is aware of the changes in the structure and function of the skin and accessory glands that occur with aging. Which of the following changes is a normal accompaniment to the aging process?
A) Thickening of collagen in the dermal layers of the skin
B) Cessation of eccrine and apocrine sweat gland function
C) Increase in the number of melanocytes in the epidermis
D) Decrease in the vascular bed of the dermis
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.
