A nurse is preparing to administer vancomycin to a child. The order is for 50 mg/kg/day in three divided doses. The client weighs 13 kg (28.6 lbs). The medication label indicates vancomycin 500 mg in 100 mL of 0.9% saline. How many mL will the nurse administer per dose? Fill in the blank. Round your answer to the nearest whole number.

Correct Answer: 43 mL

Rationale: Calculate daily dose: 50 mg/kg × 13 kg = 650 mg. Per dose: 650 mg ÷ 3 = 216.67 mg. Convert: (216.67 mg ÷ 500 mg) × 100 mL = 43.33 mL, rounded to 43 mL.
