Question 1 of 5

The nurse is caring for a client who has a prescription for cefuroxime 30 mg/kg/day PO in 2 divided doses. The client weighs 35 lb (15.9 kg). The nurse has cefuroxime 250 mg/5 mL available. How many mL should the nurse administer to the client with each dose? Record your answer using 1 decimal place.

Correct Answer: 2.9

Rationale:
Total daily dose: 30 mg/kg × 15.9 kg = 477 mg/day. Divided into 2 doses: 477 ÷ 2 = 238.5 mg/dose. Using 250 mg/5 mL: (238.5 mg ÷ 250 mg) × 5 mL = 4.77 mL. Per 2 doses: 4.77 ÷ 2 = 2.385, rounded to 2.9 mL per dose.
