amoxicillin oral suspension125 mg/5 mLper dose: V = ? mL

Practice exercise (made-up values, not clinical guidance). A child weighing 6 kg is prescribed amoxicillin 50 mg/kg/day, divided every 12 hours. The oral suspension contains 125 mg in 5 mL. What volume V do you give per dose? Round to one decimal place.

V = mL
2.Easy
cephalexin · 50 mg/kg/day · 2× per day77 lb → D = ? mg

Practice exercise (made-up values, not clinical guidance). A child weighs 77 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.
