I mainly just studied questions from Saunders 4th under the study mode to get all 3500 questions to come up and did 900 of them and you can bookmark ones you got wrong or want to go back to understand better and I read the rationals. When there was something I needed a refresher on I googled it or looked it up in my notes/books from class. I did make it a point to study up on hyper/hypocalcemia, hyper/hypothyroidism, well all the hyper/hypos. I hate those! There were about 10 prioritizing questions(who do you see first)another friend told me she had a lot of these too, 3 pictures, 10 SATA, and 4 drop and drag on procedures (not hard, just common sense:) ), maybe 10 direct drug questions. Infection control (droplet, airborne,contact) pt/staff teaching/safty. There a couple of diseases that I never heard of so I guessed that I did well enough to get the tough ones or at least that's what I told myself on the test to not stress. It all seems like a blur when you are done. JIA's mnemonics were very helpful too. I know some people say they got a lot of OB or Peds, or Cardiac. I do not believe that my test focused on anything specific. Which may seem troubling and vague, but I do think just studying questions and working on thinking them through is a good idea and when you keep getting some wrong then you know you have to study that content area. I didn't feel ready for the test and even woke up at 430am to study more LOL. I honestly thought I wasn't prepared and would fail because we learned so much in class how can they possibly narrow it down to 85-205 questions, but it wasn't nearly as difficult as I had made it in my mind.
