Which is a common sign of dehydration in older adults?

• A. Dry skin and mucous membranes, dark urine, dizziness, and confusion.
• B. Increased appetite and weight gain.
• C. Clear, colorless urine and steady balance.
• D. High energy and alertness.

Answer: (A)

Recognizing dehydration in older adults is about noticing signs of reduced body water that reflect both fluid loss and its effects on the body. Dry skin and mucous membranes show the body is short on fluids, while dark or concentrated urine indicates the kidneys are conserving water. Dizziness and confusion point to decreased brain perfusion and electrolyte imbalance that can accompany dehydration. In seniors, thirst may not be as strong, so these physical and cognitive signs are especially important to detect early. The described combination—dry skin and mucous membranes, dark urine, dizziness, and confusion—best fits dehydration. By contrast, increased appetite and weight gain aren’t signs of dehydration, clear urine and steady balance suggest adequate hydration, and high energy and alertness would not be expected with fluid deficit.
