Calculate the pediatric dosage for a drug recommended by a physician.
Answer
The pediatric dosage can be calculated as follows. Example: The physician orders a drug that has a recommended dosage of 30mg/kg/day. How much would you give a 90-lb child each day?
1. Convert 90-lb to kilograms.
90-lb x 0.45kg /1-lb = 40.5 kg
2. Multiply weight in kilograms by the ordered dose.
40.5 kg x 30 mg/day / 1kg = 1215 mg/day
3. If the orders are written for b.i.d., the dose would be divided by 2.
1215 mg/day / 2 = 608 mg/dose
