cephalexin · 50 mg/kg/day · 2× per day88 lb → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighs 88 lb. The prescription is cephalexin 50 mg/kg/day in 2 equal divided doses. Using 1 kg = 2.2 lb, find the dose D in mg given each time.

88 lb1 kg = 2.2 lb50 mg/kg/day2× per day
D = mg
2.Easy
cephalexin · 50 mg/kg/day · q8h15 kg → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighing 15 kg is prescribed cephalexin 50 mg/kg/day, divided and given every 8 hours. How many milligrams D are given per dose?

15 kg50 mg/kg/dayevery 8 h
D = mg
