Clinical Calculations: Introduction

Introduction to Clinical Calculations

How much math do I need to know?

  • To perform clinical calculations, you need to be comfortable with adding, subtracting, multiplying, and dividing fractions and decimals.
  • You need to also know how to reduce fractions to their lowest terms.
  • Higher level math, such as algebra or calculus, is not needed.

 

What do I need to learn?

  • In this course, you will learn how to correctly calculate the dose to give clients of oral (by mouth) medications, injections, and intravenous fluids and medications.
  • The prescription written by the primary health care provider is typically in grams, milligrams, micrograms, or units. You will have on hand capsules, tablets, powders, and liquids.
  • Clinical calculations involve a conversion from the primary health care provider's prescription to the item that you have on hand to ensure that you give your client the correct amount of medication.
