I have been a nurse for 18 years, I have many certification review books CPAN,CCRN and CEN. This book is the worst book I have ever ordered in my whole nursing career. [This price] for a paper back book with large fonts and a bunch of bibliography fillers to stretch it out. I wanted to send this book back after opening. What a disapointment. What is so sad is that I can't get my money back for this weak excuse for a book. I have always been a supporter of my profession. To sell this book for [the price] is a rip off to any Nurse. Honest value [is much less]I have the aspen disc which is excellent. Please save your money and buy something else that is worthy.
