Which assessment finding in a young adult client indicates a potential issue with fluid volume deficit?

The presence of poor skin turgor in a young adult client is a classic indicator of fluid volume deficit. Skin turgor refers to the skin's elasticity and its ability to return to its original position after being pinched. When a person is experiencing dehydration or lacks sufficient fluid volume, the skin may not bounce back as quickly, leading to a sign of poor turgor. This finding indicates that the body's fluid levels are inadequate, which can further affect overall health and hydration status.

In contrast, increased edema can signify fluid overload or retention, rapid weight gain often suggests an increase in body fluid rather than a deficit, and reduced urine output can also indicate dehydration; however, it is a less specific indication than poor skin turgor. While all of these factors can relate to fluid balance, poor skin turgor directly reflects the skin's response to a deficit situation.
