A dose calls for 25 mg/kg. The patient weighs 16.7 kg. What is the correct dose?

Explanation:
Dosing with mg/kg means multiply the dose per kilogram by the patient’s weight in kilograms to get the total milligrams. Here, 25 mg per kg times 16.7 kg gives 25 × 16.7 = 417.5 mg. Since mg/kg × kg cancels to mg, the total dose is 417.5 mg. This is the amount to administer.
