Correct Answer is B

Explanation

A. Decrease in systolic blood pressure: Incorrect. Aging often results in increased systolic blood pressure due to arterial stiffening, not dehydration risk.

B. Decrease in kidney function: Aging decreases kidney function, reducing the ability to concentrate urine and regulate fluid balance, increasing the risk of dehydration.

C. Increase in percentage of body water: Incorrect. Aging is associated with a decrease, not an increase, in body water, contributing to dehydration risk.

D. Increase in saliva production: Incorrect. Aging leads to reduced saliva production, not an increase, but this is not directly related to dehydration.

A. Iron supplements B. Magnesium-containing antacids C. Antibiotics D. Anticholinergics/antispasmodics E. Opioid narcotics

Correct Answer is ["A","D","E"]

Explanation

A. Iron supplements: Iron supplements often cause constipation by slowing gastrointestinal motility and hardening stool.

B. Magnesium-containing antacids: Magnesium has a laxative effect, which can lead to diarrhea, not constipation.

C. Antibiotics: Antibiotics are more commonly associated with diarrhea, not constipation, due to altered gut flora.

D. Anticholinergics/antispasmodics: These medications reduce gastrointestinal motility, leading to constipation.

E. Opioid narcotics: Opioids cause constipation by decreasing peristalsis in the intestines.
