Preface

Pathophysiology for Nurses at a Glance provides you with a concise overview of a number health‐related conditions. This text has been written with the intention of making the sometimes complex subject of pathophysiology understandable and stimulating. The human body has an astonishing capacity to respond to disease in a variety of physiological and psychological ways; it is able to compensate for the changes that occur caused by the disease process. This text considers those changes (the pathophysiological processes) and the effect they can have on a person.
Pathophysiology is concerned with the disturbance of normal mechanical, physical and biochemical functions. The word pathophysiology is a combined word from the Greek pathos, which means disease, and physiology is related to the numerous normal functions of the human body. Pathophysiology considers both the cellular and the organ changes that occur with disease, as well as the impact these changes have on body function. When something influences the normal physiological functioning of the body (such as disease), then this becomes a pathophysiological issue. It must be remembered, however, that normal health is not and cannot be exactly the same in any two people; as such, the term normal must be treated with caution.
To be able to care for people in a safe and effective manner, the nurse must have the knowledge and skills to meet needs inside and outside hospital and across health and social care, and meet the needs of an increasing older population and of those with long‐term conditions.
This text is mainly intended for nursing students who will come into contact with those who may have a variety of physically related healthcare problems such as pneumonia, diabetes mellitus and many more diseases. The focus of the text is on the adult person. It is the intention of this text to develop knowledge and skills both in theory and practice and to apply this knowledge with the intention of providing safe and effective high‐quality care. The overriding aim is to relate normal body function to pathological changes that may lead to disease processes, preventing the individual from leading a ‘normal’ life.
