When discussing hydration with an aging population, which fact is accurate according to the material?

• A. Older adults are more prone to dehydration than younger adults are.
• B. Older adults require fewer fluids than younger adults.
• C. Hydration needs do not change with age.
• D. Older adults should avoid drinking water to prevent frequent urination.

Answer: (A)

Older adults are more prone to dehydration because aging brings changes that disrupt fluid balance and thirst perception. Total body water decreases with age, and the kidneys lose some ability to concentrate urine, so fluids can be lost more easily. The thirst sensation also diminishes, so they may not feel the urge to drink even when their body needs water. Add in factors like diuretic medications, other drugs, chronic illnesses, fever or infections, and reduced mobility or cognitive impairment that make it harder to obtain fluids. Because of these factors, dehydration risk is higher in older adults than in younger individuals, even if they don’t seem dehydrated. Hydration needs do change with age, and it’s not appropriate to avoid drinking water to prevent urination; instead, encourage regular, attainable fluid intake and address factors like incontinence or access to fluids.
