In this first video of the 'Calculating Doses' module, you will learn how to work out a basic dose of a drug.

You will be working with a drug in a solution form, and you will work out the total volume of the solution to administer based on:

• The prescribed dose (how much of the drug the patient needs).
• The stock dose (how much of the drug is in a given volume of the solution).

To work out the volume you need to administer, divide the prescribed dose by the stock dose, and multiply the answer by the volume that the stock dose is in.

Now that you have watched the video, have a go at these practice questions.

Once you have had a go at the questions, if you want to take a look at the methods that we used to get to the answers, the worked solutions are available below.
