For each kilogram of a person's weight, 2.5 milligrams of a drug is to be given. what dosage should be given to a child who weighs 7171 pounds? use the fact that 1 l b equals 0.45 kg.1 lb=0.45 kg.

So, basically the question is asking what is the dose of a medication that is 2.5mg/kg.

Assuming that the child does NOT weigh 7171lbs but 71lbs; which would equal around 32kg (71 x 0.45).

So this child would have 2.5mg per 32kg. 32kg x 2.5= 80mg of medication.
