Hospital Nursing Orientation

I am a re-entry nurse. I have been hired into a hospital-based ambulatory infusion center. I am scheduled for orientation in a couple of weeks. I understand it to be a one day hospital orientation and a 3 day nursing orientation. I've heard that they do a skills competency assessment and a general medication assessment. Can anyone tell me what I might expect w/re these two areas? I've been a legal nurse consultant for the past 10 years and my previous hospital experience was OR and Labor & Delivery/Maternity. I've never worked a med/surg floor. I am terrified that they are going to hit me with something for which I am unprepared. I would love to be able to study some - especially the medication area. Any direction would be appreciated.

Thanks, Robin
