What is a common sign of dehydration in an older adult during assessment?

Dry mucous membranes and decreased skin turgor are indeed common signs of dehydration in older adults. As individuals age, their body's ability to retain water decreases, making them more susceptible to dehydration.

Dry mucous membranes, such as those found in the mouth and nasal passages, indicate a lack of adequate moisture, which is a direct result of decreased fluid intake or significant fluid loss. Similarly, decreased skin turgor refers to the skin's elasticity and hydration levels. In a hydrated individual, the skin quickly returns to its normal position when pinched. In the case of dehydration, the skin may remain elevated or "tent," which reveals that the body lacks sufficient fluid.

Recognizing these signs is crucial for proper assessment and management of dehydration in older adults, as they may not exhibit typical symptoms or may have altered sensations regarding thirst and hydration.
