Back to work! Advice please

Long story short.. have worked on and off for 10 years, FT/PT/casual, inbetween having my children. Took the easiest route and kept going back to the same small hospital on the CCU/telemetry floor. I haven't worked since December 2002, and am ready to jump into nursing again.. but only want a prn position. I have an interview Tuesday (8/3). My problem is - I do not know where I want to go. The HR lady asked me when she called to set up the interview, where I may be interested in working...(they are many many nurses short on every floor,as every hospital is) I told her I'd just like to come in and see as I wasn't sure. It would seem logical to go to a telemetry floor, but I DO not want to do that. I don't really want a steady dose of cardiac. I just kept going back to the prior hospital since I was already trained, etc..
Part of me really want to bust out and try something else, such as Emergency nursing or L&D/nursery... not sure how the orientation would work though, being I just want a casual job. It may not work.. Any thoughts?
