I started as a psych RN right out of nursing school, and after 1.5 years there, I went to Med-Surg. My psych skills were very valuable there, and the things I learned working in Med-Surg for the 6 months I stayed were very valuable after I returned to psych. I think that there are some people who just are better suited to one or the other, and I think knowing that about yourself is key. But, if you've only been in your current position for a couple of weeks, you are still in the learning curve. I would give yourself at least a few months, but ideally 6 months to a year, before deciding to change. Not only does hopping around make you look flaky (I'm not saying you are, just saying that it can look that way to employers), but you never know - you may find that you love Med-Surg once you are more comfortable. Odds are that after only two weeks in psych, you would be equally overwhelmed and frustrated. Being a psych RN is different than being a student in clinical on a psych floor. Our students are not able to do very much of the work the RNs actually do. Also, psych patients aren't immune from medical issues, and we manage IVs, feeding tubes, Foleys, wound care, mobility, incontinence, isolation precautions, etc. on our psych unit with many of our patients. Add to that the detoxing patients with CIWAs, OWLs, etc., the management of medications with very small therapeutic ranges (Lithium, Depakote) and serious side effects (agranulocytosis, neuroleptic malignant syndrome, extrapyramidal syndrome, etc.) and there is a lot of "medical" stuff involved in psych nursing. Although I do not believe you *have to* have Med-Surg experience to be a good psych RN, I do believe that the experience makes you valuable to employers and a leader with your peers when medical issues come up. I guess what I'm saying is, stick it out for a bit if you can. If you still hate it in six months, you can move (possibly even within your current hospital, without burning bridges), and what you learn in Med-Surg will be valuable to you for the rest of your career. If you jump ship now, you run the risk of burning bridges at your current employer, gaining a reputation as unreliable in the community (nursing is a small world, and you never know if the next hospital's manager will be friends with your current manager, etc...) and (most importantly, IMO) never getting to know for sure that you could be a competent Med-Surg nurse. You will do yourself a huge favor if you stick it out and leave with the confidence that comes from knowing you *can* do the job, and realizing you just don't want to, instead of leaving after only a few weeks without proving to yourself that you could do it.
JMO. Psych nursing is wonderful, and it's a calling, and I highly recommend it to anyone who feels that call. That said, you have your entire career ahead of you. Start out with a success where you're at, and move forward with the confidence gained from that success underneath you. Good luck to you!
