cephalexin · 50 mg/kg/day · 3× per day66 lb → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighs 66 lb. The prescription is cephalexin 50 mg/kg/day in 3 equal divided doses. Using 1 kg = 2.2 lb, find the dose D in mg given each time.

D = mg
2.Easy
cephalexin oral suspension250 mg/5 mLper dose: V = ? mL

Practice exercise (made-up values, not clinical guidance). A child weighing 8 kg is prescribed cephalexin 50 mg/kg/day, divided every 6 hours. The oral suspension contains 250 mg in 5 mL. What volume V do you give per dose? Round to one decimal place.
