Currently an RN extern on a PCU for 7 months. Really want to work in an ER? Could this even be possible as a new grad?

ER is a hard environment to learn in because it's fast paced. I'd suggest a year of experience in a Telemetry unit. Or you could find a really good Transition into practice program. I did a 12 week transition into practice program for ER. They allowed an extra 3 weeks if needed. I didn't end up needing the 3 extra weeks. However, if I hadn't completed the year in Telemetry beforehand I know that it would've been much much harder to transition into ER.

I would recommend getting at least a years worth of experience before going to the Emergency Department. I went straight out of school into a fellowship position and it took a while to get the hang of things. It is a very stressful environment to try to learn in. It is possible in some places though. The fellowship positions for new grads at that hospital depended on how many staffing holes we had and how many veteran staff we had. It was a great program. So- it is possible. Might be hard to come by and/ or highly competitive.
