Which is the approximate urine output target for a 70-kg adult per hour?

• A. 35 ml/hr
• B. 14 ml/hr
• C. 70 ml/hr
• D. 105 ml/hr

Answer: (A)

Urine output is a practical bedside marker of adequate renal perfusion during resuscitation. The typical adult target is about 0.5 mL per kilogram per hour. For a 70-kg person, that equals roughly 35 mL per hour. This level balances enough kidney perfusion to avoid injury with avoiding excessive fluid administration. Outputs well below this suggest under-resuscitation, while outputs well above it imply potential fluid overload. So 35 mL per hour is the best target for a 70-kg adult.
