amoxicillin oral suspension250 mg/5 mLper dose: V = ? mL

Practice exercise (made-up values, not clinical guidance). A child weighing 23 kg is prescribed amoxicillin 90 mg/kg/day, divided every 8 hours. The oral suspension contains 250 mg in 5 mL. What volume V do you give per dose? Round to one decimal place.

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.
