MOst nurses would tell you to stay on your floor and gather experience that can be used in the ER, however, if you want ER go there. With the nursing shortage as it is you can always go back to the floor you're working now or really anywhere you'd like to go. You can gain experience anywhere, my thought is this.... if you enjoy ER more then you will learn more readily there. The ER is like no other place, you have to know some of everything that means you will be fit to go anywhere you want to if you decide you're tired of the ER. Work the ER, if you want more cardiac experience then work up there a day or two or three a month. The only draw back I see for the ER for a new nurse is that it makes you cynical and distrustful of what patients are telling you.... we see a lot of drug seekers and the ER has made me think that everyone is guilty of it until proven innocent by reason of kidney stone or MI or fib/tib fracture. Plus if you do ER long enough you think everything should run on ER time.... I hate going to my doctor and waiting a few days for labs to come back, but its especially true if I have a loved one in the hospital. I want everyone to take care of "my" patient the way it would be done in the ER. STAT!!!!
Go where your heart leads you, it's usually the wisest choice. Good luck
