Question

The physician ordered Velosef (cephradine) IM 50 mg/kg/day in equally divided doses four times a day for a child who weighs 40 pounds. Convert pounds to kilograms and then calculate the prescribed dosage. ______ mg every _____ hours

Answer 1

Answer:

226.75 mg every 6 hours

Explanation:

1 pound is equivalent to 0.45 kg. Therefore 40 pounds will be equivalent to 18.14 kg.

For a child weighing 1 kg. The dose is 50 mg/kg/day in four divided doses which is every 6 hours in a day.

Therefore for a child weighing 18.14 kg. The dose to be administered will therefore be 907 mg in four divided doses for a day which can also be interpreted as 226.75 mg every 6 hours for a day.
