Question

The child should receive a dose of approximately ____ mg.(Round to the nearest integer as needed.)

Answer 1

In order to determine the size dose the child should receive, use the values

A = 5 (age of the child) and D = 800 (dose fro adults) into the given formula for the child's dose C. Then simplify, as follow:

$\begin{gathered} C=\frac{DA}{A+12} \\ C=\frac{(5)(800)}{800+12}=\frac{4000}{812}\approx5 \end{gathered}$

Hence, the child should receive a dose of 5mg
