Learning Hub: Drug Calculations

Workshop 1: multiplication and conversion

The process of drug calculations involves arithmetic which deals with the study of numbers.  This session will cover:

  • A review of mathematical terms
  • Multiplication and division by 10, 100 and 1000
  • Multiplication of decimals
  • Conversion of units

Workshop 2: fractions

The arithmetic of fractions is very important groundwork for the calculation of quantity of drugs given to patients.  This session will cover:

  • Proper and improper fractions
  • Simplification of fractions
  • Multiplication of fractions

Workshop 3: oral medication and injections

This workshop will cover how to apply the techniques learned in the previous two sessions to calculate the amount of doses for injections and syrups.  It will include:

  • Worked examples for oral medication
  • Worked examples for syrups and injections

Workshop 4: infusion rates

Drugs are administered via several routes, including by intravenous infusion.  This workshop will cover how to apply the techniques learned in previous sessions to flow rates, including worked examples for per minute and per hour drip rates by using 3 different formulae.

Please Note: 1st year students do not need to attend Session 4

Test yourself

Test your arithmetic skills before coming to a tutorial or a workshop, so that you can pinpoint the areas where you need to improve.  Have a go at:

Drug Calculations Workshops

Nurses need to facilitate the safe and accurate administration of medicines.  To do this they need to carry out basic drug calculations.

This series of workshops (and materials) have been created in order to help students understand the basic maths required in order to carry out those drug calculations.

To get the most out of these workshops it is recommended that you attend all of them.
