I just got a job as a nurse reviewer and i will be starting this june...im just wondering what to expect in that kind of job and how do i prepare for it? Is there a book that i could read?

Please help!

How is the Nurse Reviewer job? What exactly are you doing? Does it pay well? What are te days & hours like? I'm considering applying for that position at State Farm.
