You may have already made a decision about leaving your current position, but if you're still undecided, pick up the book, Cracking the Nursing Interview. It will help you with the process. You can get on Amazon and Barnes and Noble, too, I believe.
I read a book recently called Cracking the Nursing Interview by Jim Keogh. You can get it on Amazon or B&N. But it's a pretty thorough reference for anyone looking to change careers within nursing or to get into nursing from another career. It really helps with the interview process. But it also helps you know what to expect in general. I found the best part of the book is the cheat sheet in the last two chapters. It really outlines what you need to know to be a nurse.
