Increased muscle tone of the bowel
Decreased pH of the stomach
Decreased intestinal peristalsis
Increased gastric acid production
The Correct Answer is C
A. Increased muscle tone of the bowel: Aging generally leads to decreased muscle tone and motility in the bowel, not increased. This option is incorrect.
B. Decreased pH of the stomach: Aging is associated with a decrease in gastric acid production, leading to a higher (less acidic) pH, not a lower (more acidic) pH. This option is incorrect.
C. Decreased intestinal peristalsis: Aging commonly results in decreased intestinal peristalsis, which can lead to constipation and other digestive issues. This option is correct.
D. Increased gastric acid production: Older adults typically experience decreased gastric acid production, not an increase. This option is incorrect.

Correct Answer is C
Explanation
A. Apply friction when drying the client's skin. Friction can damage the skin, especially in clients with incontinence who are at risk for skin breakdown.
B. Use soap to clean the client's skin. Soap can be drying and irritating to the skin. pH-balanced cleansers are preferred to maintain skin integrity.
C. Apply a barrier cream to the client's skin. Barrier creams protect the skin from moisture, reducing the risk of skin breakdown and irritation from incontinence.
D. Use hot water to clean the client's skin. Hot water can dry out and damage the skin. Warm water should be used instead to gently clean the skin.
