A child weighing 20 kg is prescribed 60 mg/kg/day, divided every 8 hours. What is the per-dose amount in milligrams?

Explanation:
Compute the total daily dose first: multiply 60 mg/kg/day by 20 kg to get 1200 mg per day. Since dosing is every 8 hours, there are three doses in 24 hours. Divide 1200 mg by 3, giving 400 mg per dose. The per-dose amount is 400 mg.
