Prioritization and delegation, SATA, and infection control. I personally wouldn't get crazy studying one particular subject, just do as many practice questions as possible. If you get the Saunders CD you can set the questions to come up randomly and I think that is the way to go. I spent way too much time studying lab values and endocrine and the majority of my test was psych and pharm. I just thought I could've had the same result and not stressed out so much about memorizing specifics in any one area. I used the Saunders 4th edition CD, Kaplan 2010-2011 NCLEX-RN prep book, and Prioritization and Delegation by LaCharity. Good luck!!!!!
