Make sure your Epocrates is up to date and make sure you know the phone number to your hospitals pharmacy. BOth bailed me out more times than I can count. Beyond that I don't think I'd study anything special. Doesn't pay to SPend too much time with pharm texts only to learn about a lot of meds your hospital might not even stock on formulary. Other than whatever BLS/ACLS you program requires I'd probably plan to just learn on the job.
