The physician orders penicillin 500 mg orally to a child weighing 20 kg. The recommended safe dose range is 25 mg to 50 mg/kg/day. What is the safe dose range? Is this a safe dose range?
25 mg X kg = dose in 24 hours
25 mg X 20 kg = 500 mg/day
50 mg X kg = dose in 24 hours
50 mg X 20 kg = 1000 mg/day
500 mg to 1000 mg is a safe dosage range.
