Question 1 of 5
A nurse is preparing to administer cephalexin 50 mg/kg/day in divided doses every 8 hours to a child who weighs 33 lb. The amount available is cephalexin oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale: Convert 33 lb to 15 kg (33 ÷ 2.2).
Total daily dose: 50 mg/kg/day × 15 kg = 750 mg/day. Per dose: 750 mg ÷ 3 = 250 mg. Volume: 250 mg ÷ (250 mg/5 mL) = 5 mL.
