It’s okay
Format: Paperback
I’m a veteran RN who left nursing to raise my family. I let my license expire because I did not have to work, nor did I want to. I was burnt out. Anyway, I decided to get my license reinstated and instead of doing expensive refresher courses, I’m taking the NCLEX. Again. After 18 years. I just wanted to brush up on some of the topics and procedures. I don’t know… this book was okay. It was nice to have access to all the practice questions, but I did notice that a lot of times, the “correct” answers went directly against what it says in the book. I feel like that’s confusing, especially for a new grad nurse who doesn’t have much time in the field. Anyway, I wouldn’t buy this again, but I’m testing tomorrow, so we will see how it goes!

Good Information, Good Practice Questions

I got this book to study some nursing questions. Really nice book didn’t come shrink wrapped with plastic though but wasn’t damaged or anything. Covers a broad range of topics. Excellent study resource.
