The jobs that are not in bedside nursing usually require a few years of bedside nursing. Not always, but usually.
If OB is of no interest to you, then do your year or so like you said (at least a year after orientation is finished), and then apply for an internal transfer in an area of interest to you. You will probably need another bedside nursing position in a different area to get into the more specialized roles. If you are interested in psych, like you said, apply for an inpatient psych position as a staff nurse and work toward being a community health liason or psych NP down the road if advanced nursing interests you.
Many opportunities, and it's okay not to know what you want to do at less than 1 year in the field. I work nights, too (in ICU), and have done nights since I started nursing, and they are not ideal for most people. I can't wait to be on days, waiting my turn, soon
, but it's also nice to know that I enjoy ICU, and wouldn't really want to work anywhere else in the hospital setting, I don't think (other than another ICU, CCU or something lol). Maybe oncology. Once you find that place, it feels good. Maybe psych will be that place for you. My first nursing job wasn't my niche, knew that when I started, but I needed a job, gained experience (worked for 1 year there, but also had only a couple of weeks of orientation. If I had a few months like I did in ICU, I would have felt it necessary to stay for 2 years, but that's just me). Also know that no job will be perfect, but as long as you enjoy it most of the time, you're in a good place.
What is it about psych that you enjoy? If you thoroughly look at your interests and abilities, you'll be more successful in choosing your next area. Are you a good listener? Do you enjoy advocating for people that can't speak for themselves, much stigma attached? (I considered psych, too, and don't let people talk you out of it if that's what you want. People will say,"Oh, I couldn't do that. Why would you want to do that?" etc). They also say that about my job, and it's not an easy job, but I find it rewarding because I enjoy the acuity, and helping people through one of the hardest times of their lives, also how thorough I can be with 2 patients. If psych is it, then good!
Best of luck!
