Which test would you use to assess hydration status in a patient?

Using skin turgor as a test to assess hydration status in a patient is effective because it directly evaluates the skin's elasticity and how well it retains moisture. When a patient is properly hydrated, the skin should have good turgor, meaning it quickly returns to its normal position after being pinched. Conversely, in a dehydrated individual, the skin may show decreased turgor, remaining tented for a longer period.

This method is simple and can be performed quickly without the need for specialized equipment, making it a practical choice in a clinical setting. In contrast to other options, such as bowel sounds, which primarily assess gastrointestinal function, or temperature checks, which indicate fever or infection rather than hydration status, skin turgor specifically reflects the body's fluid balance. Capillary refill time can provide some insight into perfusion and fluid volume but does not offer a direct assessment of hydration unlike skin turgor.
