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

19.2737 milligrams of aspirin that should be administered.

Explanation:

Mass of an infant = 8.5 pounds = 8.5 * 0.4535 kg=3.8547 kg

Aspirin dosage per 1 kilogram = 5 mg

If an infant weights 3.8547 kg, the dosage required will be;

3.8547 * 5 mg=19.2737 mg[/tex]

19.2737 milligrams of aspirin that should be administered.

Answer;

19 mg

Explanation;

dose = 5.0 mg/kg

weight of infant = 8.5 pounds

Convert 8.5 pounds to kg: 8.5 pounds = 3.86 kg

Therefore;

The dose to give the infant is:

= (5.0 mg/kg) x (3.86 kg)

= 19.3 mg

≈ 19 mg
