I'm feeling at a low right now. I worked on a cardiac intermediate floor for one year prior to transitioning to the ER. New to ER nursing, I had about 3-4 weeks of training with a preceptor and then was let off orientation. I didn't feel ready but management and my preceptor felt there was nothing more to teach me, otherwise I'd be on orientation forever. I've learned so much since then...I started orientation in August, and started on my own in September. So I've been on my own about 6-7 months now... and for a while I felt like I was getting the hang of things. I question things that don't seem right and can almost point out if a patient needs to be intubated. They tell me I carry a black cloud as well...anyway, i felt I was getting it but the last two weeks, I've lost that feeling. I'm not sure why, mainly I feel like it's my pace. I feel too slow, and like I've taken some steps back. My manager says I'm doing fine...But i feel like when it's busy, I get overwhelmed and show it. I also get scared I'll miss something, or not prioritize correctly. I obviously won't know everything, but I hate that feeling. I was a nurse prior to this and felt comfortable where I was...now I don't feel as competent. Is this normal? Should I give it more time or am I just not cut out for the ER? I love the ER and dread holding patients...and lately we've been holding a lot. 😑 I don't miss the floor whatsoever.
