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

A. Tenting of the skin is a classic sign of dehydration. When the skin is pinched and does not return quickly to its normal position, it indicates a lack of fluid in the body. This is a common finding in dehydration, particularly in older adults. B. Loss of skin elasticity is a natural part of the aging process and may not be directly related to dehydration. It is common in older adults and is not necessarily an indicator of fluid status. C. Warm and dry skin can be a sign of dehydration, particularly if accompanied by other symptoms such as a dry mouth or increased heart rate. Dry skin occurs when there is insufficient moisture in the body, which is common in dehydration. D. Thinning hair in the lower extremities is more often associated with circulation issues or aging. It is not a typical sign of dehydration and would not be used as a primary indicator for assessing hydration status.
