When assessing an older adult client, which finding is most indicative of dehydration?

A. Skin tenting is a sign of dehydration. It occurs when the skin, after being pinched, does not quickly return to its normal position. This is often seen in areas with loose skin such as the subclavicular region. B. Loss of skin elasticity is a normal aging process and not specifically indicative of dehydration. It can be seen in older adults regardless of hydration status. C. Warm and dry skin can be a sign of dehydration. Dehydration leads to reduced sweating, which can result in dry skin, and it may also increase the body temperature, making the skin feel warm. D. Thinning hair, especially in the lower extremities, is typically associated with circulatory issues or aging. It is not a direct sign of dehydration.
