What are common signs of dehydration in older adults?

• A. Increased appetite, high blood pressure, and dry skin
• B. Dry mucous membranes, confusion, and low urine output
• C. High body temperature and lethargy
• D. Excessive thirst and frequent urination

Answer: (B)

The signs of dehydration in older adults are particularly important to recognize, as this population is at a higher risk for dehydration due to physiological changes and possible mobility issues. The correct answer encompasses key manifestations associated with inadequate fluid intake or loss.

Dry mucous membranes indicate a lack of adequate hydration, as mucous membranes typically remain moist with sufficient fluid levels. Confusion or altered mental status is a critical sign that can arise from dehydration, as even mild fluid deficits can impact cognitive function and lead to increased risk of falls and other complications. Low urine output reflects the kidneys' response to conserve water in a dehydrated state, further signaling that the body is not adequately hydrated.

Recognizing these specific indicators can help caregivers and healthcare providers respond promptly to a potentially serious condition, allowing for timely rehydration and prevention of more severe complications associated with dehydration in older adults.
