Definitely Recommend
Format: Paperback
This book is very helpful and I definitely recommend it as a resource. It simplifies complex concepts and is organized by body system. It highlights the major health conditions in each body system and provides a simple and concise explanation. At the end of every concept a mini quiz is offered to test comprehension. I’ve found this book very useful during the semester and I’m sure I’ll find it helpful for boards.

It's good but Leik is better
Format: Paperback
This is a fairly good review book for the FNP exam and I've had professors recommend it's use. However, the review book by Leik is better in that it delivers information in a short-and-sweet way that still covers the most crucial information. Fitzgerald requires a little more reading and unfortunately I just don't have the attention span for that anymore. I need short paragraphs, bullet points, and the most crucial information that will give me success for the FNP exam and Leik provides that a little more than this.
