Question

The recommended dosage of a drug for pediatric patients is 200 mg per kilogram of a​ patient's weight. If Janine weighs 102 ​lb, how much of the drug should she ​receive? Use the fact that 1 lb = 0.45 kg

Janine should receive about ____ milligrams of the drug.
​(Round to the nearest milligram as​ needed.)

Answer 1

Answer: 9180 mg

Explanation:

First we must convert the patients weight from lb to kg.

102lb x
`(0.45kg)/(1lb)` = 102 x 0.45 kg = 45.9 kg

Now to calculate the amount of the drug she should receive.

45.9 kg x
`(200mg)/(kg)` = 9180 mg
