Question

The order is 500 mg of Rocephin to be taken by a 7 kg infant every 8 hours.

The medication label shows that 75-150 mg/kg per day is the appropriate dosage range. How much will the patient receive per day? Is this within the normal range?

the range i got was 525-1050 mg per 24 hours

Answer 1

To compare the ordered dose to the acceptable dose, let us get the ordered dose into the same units as the acceptable dose, i.e. mg/kg/day.

500 mg/7 kg/8 hours x 24 hours/day = 214 mg/kg/day. This is what the patient will receive per day.

This is not within the acceptable range, as it is too high.
