Part I

Getting Started with Nursing Calculations and IV Therapy

For Dummies can help get you started with lots of subjects. Visit www.dummies.com to discover more and do more with For Dummies books.

In this part …

Use the practice-makes-perfect theory and check your understanding of working with fractions and decimals.

Become familiar with working with percentages, averages and ratios, because these skills are often used in healthcare to give a quick indication of specific quantity and when making comparisons.

Know how to use moles, millimoles and solution concentrates in order to describe the amount of substance and for electrolyte measurements: for example, ‘body sodium levels 133–146 mmol/l’.

Interpret doctors’ instructions on prescription charts and medical terminology, including the 24-hour clock, so that when administering medications you know that ‘0800 hours’ means ‘8:00 a.m.’ and ‘20:00’ hours means ‘8:00 p.m.’, to avoid any confusion.

Chapter 1

Getting the Lowdown on Nursing Calculations and IV Therapy

In This Chapter

Understanding the basic maths required for healthcare

Knowing IV therapy and its correct administration

Being clear on complications

Intravenous (IV) therapy is one of the most common clinical skills that healthcare professionals perform. It includes administering IV drugs, fluid replacement (including blood and blood products), cytotoxic therapy (chemotherapy) and parenteral nutrition (which doesn’t mean your mum and dad providing a hot meal when you pop home to get your washing done (!) but feeding ‘not via the alimentary canal’). Intravenous therapy can also take the form of administering emergency fluids and medications, such as when individuals have sustained huge blood loss, and/or to convert heart arrhythmias back to sinus rhythm.

In this chapter, I describe how this book takes you through the whole IV process – showing you how to walk before you can run. I help you get to grips with the mathematics and formulae necessary to work out the amounts of drugs or fluids to administer through the main routes, including oral, and translating doctors’ written instructions (which can be tricky at the best of times!).

This book also describes the types of IV therapy and how they can relate to patients’ blood tests obtained by venepuncture (flip to Chapter 11 for more) as well as their medical condition. I explore methods of getting the medications into the IV route as well as looking at the legal and professional aspects of IV therapy and complications associated with specific routes of administration.

Whatever your reason for entering healthcare, you share a common goal with all nurses and other healthcare professionals. You want to make your sick patients better, keep your healthy patients healthy and provide high-quality care to people, including those at their end-of-life journey.
