A nurse is caring for a 10-month-old weighing 17.6 lb (8 kg) who was admitted for dehydration. The infant has an IV of 5% dextrose in 0.45% saline infusing at the maintenance rate of 100 mL/kg per day for children weighing 22 lb (10 kg) or less. The infant has vomited five times in the last 3 hours and has had no wet diapers in the last 8 hours. The nurse informs the health care provider. Which prescription should the nurse question?

Increase the intravenous fluids to 45 mL per hour for 24 hours. Administer a 10 mL/kg fluid bolus of dextrose 25%. Keep the infant on nothing-by-mouth (NPO) status while vomiting persists. Maintain strict intake and output (I&O), weighing all diapers.
