Which of the following is a good indicator of adequate hydration in a renal donor with diabetes insipidus?

• A. Sodium greater than 150 mEq/L
• B. CVP of 8cm H20
• C. Urine output of 500cc/hr
• D. Sodium less than 150 mEq/L

Answer: (D)

In the context of assessing hydration status in a renal donor with diabetes insipidus, maintaining optimal sodium levels is crucial. In this case, a sodium level of less than 150 mEq/L would indicate adequate hydration. Diabetes insipidus leads to excessive urine production and can result in significant fluid loss. In such individuals, when hydration is adequate, sodium levels are typically within a normal range, as proper fluid intake helps to dilute the sodium concentration in the blood. Conversely, a sodium level greater than 150 mEq/L suggests hypernatremia, which can occur due to dehydration. Therefore, observing a sodium level less than 150 mEq/L is a positive sign of proper hydration, indicating that the body is sufficiently hydrated and fluids are being retained adequately in the presence of diabetes insipidus. Other indicators, such as central venous pressure (CVP) or urine output, while important, may not directly reflect the hydration status as clearly as sodium levels do in this specific scenario.
