Question

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to give?

Answer 1

Hello!

The answer is: The correct dose of medication to give is 5.6 mL

Why?

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

`(125mg)/(5mL)=1\\\\125mg=5mL`

The available solution means 125 mg each 5 mL of solution, so:

`(125mg)/(5mL)=(140mg)/(x)\\\\x*(125mg)/(5mL)=140mg\\\\x=140mg*(5ml)/(125mg)=(700mg*mL)/(125mg)=5.6mL`

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!
