4. Drug strength as a ratio
In this fourth video of the 'Calculating Doses' module, you will learn how to work out the volume of a solution to administer when the drug strength is given as a ratio.
The ratio tells you how many grams of the drug are in how many millilitres of the solution, and you can use these values as the 'stock dose' in your basic drug calculation.
Now that you have watched the video, have a go at these practice questions.
