[B]You don't have enough experience.[/B]
You need medical surgical as you will float even if they tell you otherwise. Recruiters will tell you things that are not true.
You may or may not get team help during a crisis, they may be too busy.. I've been places that no one will even talk to you let alone HELP. Except for the Rapid Response Team, but, still you have to do everything, call the Dr., give the meds, etc. It's all up to the primary..
So, with that said, get yourself on a med/surg floor and gain more experience.
