Patient safety is a predominant feature of quality healthcare and something that every patient has the right to expect.  As a nurse, you must consider the safety of the patient as paramount in every aspect of your role; and it is now an increasingly important topic in pre-registration nursing programmes. This book aims to provide you with a greater understanding of how to manage patient safety and risk in your practice. The book focuses on the essentials that you need to know, and therefore provides a clear pathway through what can sometimes seem an overwhelmingly complex mass of rules, procedures and possible options.

Key features:

·         A practical introduction to patient safety and risk management written specifically for nurses and nursing students

·         Case studies and scenarios help you to apply patient safety and risk management principles to actual practice

·         Each chapter is mapped to the relevant NMC standards and Essential Skills Clusters so that you can see how you are meeting the professional requirements

·         Activities throughout help you to think critically and reflect on practice.
