What factor increases the risk of respiratory infection for older adults?
Inadequate hydration
Decreased physical activity
Decreased ciliary action
Poor personal hygiene
The Correct Answer is C
A. Inadequate hydration: Can contribute to thickened secretions but is not the primary age-related factor in respiratory infections.
B. Decreased physical activity: May contribute indirectly to overall health decline but is not specific to infection risk.
C. Decreased ciliary action: Aging reduces ciliary function in the respiratory tract, impairing the clearance of pathogens and increasing infection risk.
D. Poor personal hygiene: While hygiene is important, it is not a typical physiologic age-related factor for respiratory infection.

Correct Answer is D
Explanation
A. Slower gastric emptying of fluid
This affects digestion, not necessarily bowel motility or stool formation. It is not the primary factor in constipation.
B. Decreased hydrochloric acid
This may impair digestion but is not directly responsible for constipation.
C. Abdominal bloating
Bloating is more of a symptom than a cause. It may occur after constipation develops.
