A dose calls for 0.25 mg/kg; the patient weighs 98.8 kg. What is the correct dose?

Explanation:
Multiplying the dose per kilogram by the patient’s weight gives the total dose in milligrams. So 0.25 mg/kg × 98.8 kg equals 0.25 × 98.8 = 24.7 mg. (You can also see this as 98.8 ÷ 4 = 24.7 since 0.25 is 1/4.) Therefore the correct total dose is 24.7 mg.
