Been an RN since 1982, LPN (Army trained) for 5 years prior to that.
"Retired" from the profession in the late 90's...............I worked almost exclusively in ER, Cardiovascular/open heart surgical recovery, neonatal ICU, and Surgical/Medical ICU.
Got very tired of patients dying on me.....especially the children.
Can be a very rewarding profession with no shortage of job openings. But be prepared for patient families with no patience, doctors who slough off parts of their jobs onto you, doctors with patients who are going bad at 2am and tell you to "deal with it until I get there in the morning", lots of grunt work, and lots and lots of paper work.
Make sure you keep your malpractice insurance up to date and get the most you can afford. If you have poor writing skills, brush up on them..........documentation is everything in the profession.
After you get your RN and have worked for a while, there are several avenues open to you that may be very attractive, such as Nurse Anesthetist and Family Nurse Practitioner. The former is essentially works an anesthesiologist, and the latter works essentially as a family practice MD......both under the "direct" supervision of the appropriate physician.
Good Luck and it's one hell of a job!!!
By the way......since you are a guy, be prepared for a few things: the idiots with the "gay" jokes and the women who cannot tolerate men in the profession.......remember this is a profession run by women and has its consequences, like the governing board not being able to make one standard for RN education. They've been feuding over that for almost 3 decades and still cannot reach a consensus.......there are three avenues to RN: 2 yr. ASN, 3 yr. diploma (most run out of hospitals but are disappearing), and the 4 yr. BSN. You can contrast this to the male-run MD world where there is one standard of education nationwide.......makes one wonder sometimes why the women cannot agree on much of anything.
Make sure you go to a school that's more clinical-skilled oriented vs. management-oriented. Management skills can be learned anywhere, but shorting yourself in the beginning with little clinical work during school, as a lot of BSN programs seem to do....not all, but a lot, will make it a bit more difficult on transitioning to the "real world" of nursing.
