A must have for FNP students
Format: Paperback
This book was a life saver! Chapters really explained everything easily and the test questions were very similar to what I saw on tests. Best of all, the questions gave rationales which helps solidify the information. This book is worth its weight in gold! Get it!

Worth the buy
Format: Paperback
Helpful. I prefer this little guy over the gigantic book we were required to purchase along with this one. Barely opened the bigger one, only used this for my advanced assessment course and still got an A.
