Drug calculations – A quick revision

CPD hours:
1

Drug calculations are an essential nursing skill. Regular practice and self-testing is required to help reinforce knowledge and prevent medication errors.

This module is part of our short module series, designed to provide a brief overview of the subject matter.

This module is on drug calculations for three types of medications: oral tablets, mixtures and solutions, and intravenous medications. As a refresher, it offers a step-by-step guide for how to undertake calculations.

You will have the opportunity to test your knowledge with the problems and solutions offered throughout.

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.
