By the time I reached Chapter 3, I had encountered at least four typos. It makes me question the authenticity of this author's research. If THIS many grammatical errors were allowed to make print, I can only imagine how little time and effort the author/editor put into the creation of this book. And to continue with what someone else said, this author is not even a nurse.If you are going to spend money on a book about nursing, do not buy this book. Find an author who has more hands-on experience in the field. I found most of the information in this book to be vague, or easily obtainable with a little internet research. Very disappointing.
