What is the dosage for velosef (cephradine) im 50 mg/kg/day in equally divided doses four times a day for a child who weighs 40 pounds?

Answer = 227.5 mg

Explanation

Weight of the child = 40 pounds
Convert weight to kg
2.2 pounds = 1 kg
40 pounds = 40 pounds ÷ 2.2 pounds/kg
= 40/2.2 kg
= 18.2 kg (Approximately)

The dose is 50 mg/kg/day
Therefore, daily dose for a child who weighs 18.2 kg
= 18.2 kg * 50 mg/kg/day
= 910 mg/day

We were told that the medication is to be administered in equally divided doses four times a day

Number of administration a day = 4 per day
Dose per day = 910 mg/day
Dosage per administration = 910 mg ÷ 4
= 227.5 mg
