Question

A patient is to receive medication at the rate of 0.4mg per kilogram of body weight. How many milligrams will you administer if the patient weighs 50kg? Round your final answer to 2 decimal places if necessary.

Answer 1

You know that the patient is to receive the medication at this rate:

`0.4(mg)/(Kg)`

Let be "x" the number of milligrams you will administer the medication if the patient weighs 50 kilograms.

Using the data given in the exercise, you can set up this proportion:

`(0.4)/(1)=(x)/(50)`

Solving for "x", you get:

`\begin{gathered} (50)(0.4)=x \\ \\ x=20 \end{gathered}`

Hence, the answer is:

`20mg`
