A child who weighs 40 kg is prescribed clarithromycin 15 mg/kg per day for 10 days in two divided doses for acute strep throat. If the medication is provided in suspension with 250 mg/5 mL, how many total milliliters of medication are required to complete the treatment? Record your answer using a whole number.
Correct Answer: 120
Rationale: Daily dose = 15 mg/kg X 40 kg = 600 mg/day. For 10 days, total dose = 600 X 10 = 6,000 mg. Suspension is 250 mg/5 mL, so 1 mg = 0.02 mL. Thus, 6,000 mg X 0.02 mL/mg = 120 mL.
