Drug Calculations for Nurses: A Step-by-Step Approach 3rd Edition

Book Preface

Drug treatments given to patients in hospital are becoming increasingly complex. Sometimes, these treatment regimes involve potent and, at times, new and novel drugs. Many of these drugs are toxic or possibly fatal if administered incorrectly or in overdose. It is therefore very important to be able to carry out drug calculations correctly so as not to put the patient at risk.

In current nursing practice, the need to calculate drug dosages is not uncommon. These calculations have to be performed competently and accurately, so as not to put not only the nurse but, more importantly, the patient at risk. This book aims to provide an aid to the basics of mathematics and drug calculations. It is intended to be of use to nurses of all grades and specialities, and to be a handy reference for use on the ward.

The concept of this book arose from nurses themselves; a frequently asked question was: ‘Can you help me with drug calculations?’ Consequently, a small booklet was written to help nurses with their drug calculations, particularly those studying for their IV certificate. This was very well received, and copies were being produced from original copies, indicating the need for such help and a book like this.

The content of the book was determined by means of a questionnaire, sent to nurses asking them what they would like to see featured in a drug calculations book. As a result, this book was written and, hopefully, covers the topics that nurses would like to see.

Although this book was primarily written with nurses in mind, others who use drug calculations in their work will also find it useful. Some topics have been dealt with in greater detail for this reason, e.g. moles and millimoles. This book can be used by anyone who wishes to improve their skills in drug calculations or to use it as a refresher course.
