A nurse is caring for a 5-year-old child who has nephrotic syndrome who weighs 12 kg (26.5 lb) and is postoperative following open-heart surgery. Which of the following findings suggests that the management has been effective?

A. A temperature of 37.2°C (99°F) is slightly elevated but not a major concern post-surgery.B. Urine output 256 mL over 8 hr: In a child with nephrotic syndrome, adequate urine output is crucial. For a child weighing 12 kg, an output of around 30 mL/hr (or 240 mL over 8 hours) is considered normal. 256 mL over 8 hr indicates adequate urine productionC. No pain with voiding is a positive sign but doesn't necessarily indicate overall effectiveness of treatment for nephrotic syndrome.D. Odourless urine is a normal finding and not necessarily an indicator of treatment success.
