OK, here is what I've heard:
when I did OB, I wasn't a "real nurse" because my patients "weren't sick, just having babies."
when I did ER, I wasn't a "real nurse" because I would see and discharge a patient in the matter of an hour, and real nurses had their patients for a long time.
when I did clinicals in the OR, those nurses weren't a "real nurse" because their patients were asleep.
Med/Surg: those weren't "real nurses" because they had so much help from CNAs and LPN's, the RN would "only see your patients once a day for an assessment."
So really, where are the real nurses? It seems to me like we're all faking.
Seriously though, do what you want to do. I don't know why random people's opinions matter so much to others these days.... your only judge is your mamma and your God, so do right by them and yourself, and you'll be fine.
