Question

Your child is prescribed amoxicillin (40mg/kg/day; not to exceed 1500 mg per 24 hour period) to be given 3 times

per day. If she weighs 81 pounds, what is the maximum dose that she

should receive

? (

round to the

nearest

milligram

)

Answer 1

I kilogram equals 2.20 pounds (rounded to 2 decimal places), so the child weighs 81/2.2 or 36.81 kg (again rounded). Since she was prescribed 40 mg/kg/day, that would be 40*36.81 or 1472.72 mg daily, which is below the daily maximum. Since she is to take it divided into 3 daily doses, each dose would be 1472.72/3 or approximately 490.91 mg per dose or rounded up to 491 mg.
