azithromycin · 10 mg/kg/day · q24h25 kg → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighing 25 kg is prescribed azithromycin 10 mg/kg/day, divided and given every 24 hours. How many milligrams D are given per dose?

25 kg10 mg/kg/dayevery 24 h
D = mg
2.Easy
amoxicillin · 90 mg/kg/day · 3× per day22 lb → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighs 22 lb. The prescription is amoxicillin 90 mg/kg/day in 3 equal divided doses. Using 1 kg = 2.2 lb, find the dose D in mg given each time.
