A nurse is monitoring urine output in a 14-year-old patient weighing 53 kg. What is the expected urine output over a 24-hour period?

Choice A reason: 590 mL is significantly below the expected range for a 53 kg adolescent. Using standard pediatric fluid calculation formulas, this volume would suggest oliguria or inadequate renal perfusion, which is not typical for a healthy adolescent. Choice B reason: 384 mL is far below the expected daily urine output for a 53 kg adolescent. This volume would be concerning for acute kidney injury or severe dehydration. Choice C reason: 1272 mL is within the expected range for a 53 kg adolescent. Using the standard pediatric urine output formula of 1 mL/kg/hour, the expected output over 24 hours would be approximately 1272 mL (53 kg × 24 hours = 1272 mL), which aligns with normal renal function. Choice D reason: 1960 mL is on the higher end of the normal range but may exceed typical expectations for a 53 kg adolescent unless fluid intake is excessive or diuresis is occurring. While not necessarily pathological, it is less representative of average output.
