amoxicillin · 40 mg/kg/day · 2× per day33 lb → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighs 33 lb. The prescription is amoxicillin 40 mg/kg/day in 2 equal divided doses. Using 1 kg = 2.2 lb, find the dose D in mg given each time.

33 lb1 kg = 2.2 lb40 mg/kg/day2× per day
D = mg
2.Easy
cephalexin · 50 mg/kg/day · q6h24 kg → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighing 24 kg is prescribed cephalexin 50 mg/kg/day, divided and given every 6 hours. How many milligrams D are given per dose?

24 kg50 mg/kg/dayevery 6 h
D = mg
