Question

A dose of aspirin of 5. 0 mg per kilogram of body weight has been prescribed to reduce the fever of an infant weighing 8. 5 pounds. The number of milligrams of aspirin that should be administered is.

Answer 1

19.3 mg are needed

Step-by-step explanation:

You can go about solving this in two different ways the first way/ hardest way is to convert the aspirin dose from mg/kg body weight to mg/ lbs body weight and then multiply by the 8.5 lbs body weight. The second/ easier way to get the answer would be to convert the infants body weight from lbs to kg. Then, multiply that by the dose, which will give you 19.3 mg. The math for that is below. Remember always start with the information that you know, to find the information that you don't know.

`\frac{8.5 \: lbs}{} * (1.0 \: kg)/(2.205 \: lbs) * (5.0 \: mg)/(kg) \\ = 19.27mg`
