Medications: Calculations test

CPD hours:

Medication calculations are an essential element of the competency of nurses and midwives. The safe prescribing, dispensing and administration of medications are critical in preventing adverse events associated with errors.

When errors do occur, the results can be catastrophic. Nurses and midwives work in ever increasing high pressure environments - this coupled with the increased use of medications in all areas of health care increases the risk of error.

The reduction of medication errors in health care is a national priority and nurses and midwives remain at the forefront of initiatives to reduce errors.

According to the Australian Safety and Quality Council of Australia, those initiatives are working and Australia is seeing a gradual decline in the proportion of medication errors.

At the most basic level, any medication error risk management strategy will include ensuring competency in medication calculations for anyone involved in medication administration.

There is no room for error in calculations.

Nurses and midwives are required to test their competence in medication calculations annually. No less than 100% accuracy is required.

If you are a nurse working in paediatrics or neonates, this test is not suitable as an annual competency test.

Whilst it does provide some questions on paediatric calculations based on weight, it is insufficient to ensure competency for those working full time in these specialities.

This module is a medication calculations test.

  • It requires a 100% pass mark
  • There is one try for each question
  • If one question is answered incorrectly, the test will not be passed

Please read each question carefully before answering. If rounding to the nearest whole number please round up.


This module is a medication calculation test only. It does not provide tuition on calculations and nor does it provide learning on medication safety. Medication safety involves far more than competence in medication calculations.

We recommend that everyone undertake the module - ‘Medication: safety and calculations’.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

At the end of this module participants will be able to:
