I think some of the new nurses get into it for the wrong reasons like thinking it's and easy job to make pretty good money at but then find there's much more work involved then there was in school when you took a patient or 2 and wrote papers and you deal with real co-workers, docs, families, central supply, dietary, pharmacy. When you're a student you can tell the charge nurse someone didn't get their tray, you don't have the supplies you need, someone else signs off orders and talks to docs on the phone.
Some older nurses just burn out from same thing different day, increased paperwork, government regulations, less patient care time, weekends and holidays and nights. (I had a boyfriend of pregnant woman ask me the other day if we were open in the evenings so they could come then for non-stress testing...wanted to hand him a sign and say nope the hospital is only open from 9-5 sorry)
Just remember there are many roads to take in nursing and you don't have to remain in one area if you don't like it or even remain at the same facility some are ran better then others.
