Which of the following is a common sign of dehydration in older adults?

• A. Dry mouth, dark urine, decreased skin turgor, dizziness, and confusion.
• B. Increased appetite and energy.
• C. Weight gain.
• D. Excessive sweating only.

Answer: (A)

Dehydration shows up in older adults as signs that the body is short on fluids, affecting mucous membranes, urine concentration, skin, and brain function. Dry mouth happens when saliva decreases with fluid loss, so the mouth feels parched. Dark urine indicates the kidneys are concentrating urine to conserve water, giving a deeper color. Decreased skin turgor shows skin that doesn’t bounce back quickly after being pinched, which reflects reduced skin hydration and elasticity that can be more noticeable with age. Dizziness arises from lower blood volume and orthostatic shifts, and confusion can occur as the brain receives less blood flow and electrolytes become imbalanced.

The other options don’t align with dehydration signs: increased appetite and energy aren’t typical indicators of lack of fluids; weight gain suggests fluid retention or other issues; excessive sweating by itself isn’t a reliable or common sign of dehydration in older adults.
