How can hydration status be assessed in rehab beyond subjective thirst?

• A. Urine color, urine specific gravity, body weight change, capillary refill, and skin turgor.
• B. Urine color alone is sufficient.
• C. Hair color and nail polish.
• D. Blood pressure readings only.

Answer: (B)

Hydration status in rehab is best judged with a combination of objective signs rather than thirst alone. Each indicator provides different information about fluid balance and tissue status, and together they give a clearer picture.

Urine color offers a quick, practical check of how diluted or concentrated the urine is, but it can be influenced by diet, supplements, or medications. Pairing that with urine specific gravity gives a more reliable measure of urine concentration and kidney response to hydration status.

Tracking body weight before and after activity directly reflects fluid losses or gains, making it a practical proxy for overall hydration during rehab sessions. Capillary refill and skin turgor add insight into peripheral perfusion and tissue elasticity, which can change with fluid depletion and dehydration.

Options like hair color and nail polish aren’t related to hydration, and relying on blood pressure readings alone can be misleading since blood pressure is affected by many factors beyond hydration. In practice, using the combination of urine color, urine specific gravity, body weight change, capillary refill, and skin turgor provides the most reliable sense of hydration status and helps guide rehydration strategies.
