Perhaps you need more solid experience before you continue to work in a float pool -- it's a different type of nursing altogether. I If, in your facility, is that floaters are expected to take full assignments with a relatively short orientation (or none), then perhaps you need continue to advocate for yourself, get more experience, or change positions. You are in charge of your career. Don't take an assignment which you feel is unsafe. On the other hand, I imagine that the other nurses are also overwhelmed with their assignments and also feel that they can't possibly admit another patient and give safe care.
Regarding your comment that one patient really was an ICU patient -- I'm certain that most nurses on this board would shake their heads up & down in agreement. We've all been there ...
Best of luck ... it takes time to feel that you are "settled" into a nursing position, but it is especially challenging when you work in a float pool. Your cardiac background will serve you well in your med-surg practice, but med-surg (like cardiology) is a specialty -- you need to know your stuff (and find your resources!)
Best of luck to you & Happy New Years. You control your career ... be happy.
