I agree with most of what has already been posted, but one thing I didn't see, that has made the biggest influence on my time in the ER, has been the ability to work as part of a team. You can be a nurse anywhere. You can get the skills you need to use for any situation and the book knowledge from so many sources, but the only place you can really learn to be a successful ER nurse is in the ER. My first shift in the ER (after working 3 years on a step-down telemetry unit), my unit mentor asked me what the biggest difference was that I had noticed so far... and without hesitation, I replied "you guys help each other!". Don't get me wrong, I had a wonderful staff of folks to work with on the telemetry unit and still remain friends with many of them today, but the team-work in the ER is completely different from any other unit anywhere. It's one thing to get assistance moving or changing a patient, or having someone there to help you with things you don't understand to begin with, but it's totally different when you get the cardiac red, the stroke alert, or the respiratory distress and all of a sudden, there are people helping you that you may or may not have even realized were working that shift. Before long, you've got your patient stabilized and waiting for transport and you're in the next room helping someone else with their patient. That team-work is probably the most important thing in the ER and probably the most taken-for-granted. Since I've been a nurse-leader with my department, I've seen more than one new grad not figure out how to be a 'team player' even with coaching, and see them treading water for their first several months before they realize that the expectation is not that you're able to handle each crisis on your own, but that you're part of the team that can resolve the crisis and move on to the next. The ones who don't make that realization or cannot make the connection are the ones we gently persuade to find a different department where they can be more successful. Some of them have been excellent nurses, but in order to be a "good" ER nurse, you have to understand that your team is one of the most important tools in your orificenal. (especially to help with those other skills.. until you've become a master at most of them yourself - the things mentioned by my colleagues in previous posts.. IV starts, NGT placement, etc.) Good luck to you in the future! I hope you do well and find a great team for yourself!
