A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours. How many mg should the nurse administer each day?

Step 1: Convert the child's weight from pounds to kilograms. 55 pounds ÷ 2.2 lbs/kg = 25 kg Step 2: Calculate the total daily dose using the child's weight and the prescribed dosage. 25 kg × 150 mg/kg/day = 3750 mg/day The nurse should administer 3750 mg of cefotaxime each day.
