This book was written to meet the educational needs of the student, the learner, the educator, and the nursing assistant.

Its aim is to help each of us, not only during the course of our studies or teaching engagement with the subject of nursing, but also for future reference at any time.

In writing this book, an effort was made to present indicative and not exhaustive answers in a simple and understandable way for the benefit of all. These answers reflect contemporary practical applications of the nursing specialty and the profession in general.

The author and the working group believe that the content of this book will be a useful aid.
