Answer to Question 2
D
With age the skin loses its resiliency and moisture, and sebaceous and sweat glands become less active. These changes often lead to dry, cracked skin. Daily bathing, inadequate fluid and nutri-tion, and the use of some soap products can cause the skin of an older adult to become too dry. As the epithelium thins and elastic collagen fibers shrink, the skin becomes fragile and subject to bruising and breaking. Activities such as turning and repositioning and washing the skin and perineal tissues can cause impaired skin integrity.
