This groundbreaking new resource, sponsored by the American Society of Pain Management Nurses covers the entire spectrum of topics in the practice of pain management nursing.
I read this book cover to cover and then used Pain Management Nursing Exam Flashcard Study System from Mometrix Test Preparation to study for the certified pain management exam. These 2 things are all you need to pass the test.
This is an excellent book for review. It's very detailed but covers everything you need to know for certification.
