Hi, I'm not a RN yet either. However, my wife has been a RN for about 28 years. I can ensure you that there is much more to nursing than just tending to someones personal hygiene. She works on a Neo Natal floor, splitting time between the nursery and with the mothers on the floor. Her job is not nearly as fast paced as the ER, but it's not without it's own adventures. Over the years I've heard about women who crash on the floors and the RNs are the first on scene providing life saving support (CPR) until the Doctor arrives. Even then they are fully involved with pushing meds, pumping the chest, providing O2, blood, or whatever is required. Additionally, they are carefully monitoring vitals throughout the shift on mommas and babies. Blood Sugars, signs of internal bleeding, O2 Stats, BP, pulses, are just some of what they carefully monitor. In addition they are looking for symptoms like confusion, skin tone, pupil dilation, blueness around the babies mouths, dizziness, nassau, abnormal pain, etc. If the RN misses anything, it could mean death in a worse case scenario. I just described the role my wife plays on a non emergency care floor; her shift is tame compared to what you will see in the ER.
Good Luck with your career choice, don't let anyone talk you out of your goal. Oh, by the way, the pay is pretty good. Most years she makes mid-70,s. This past year, because she worked part time to finish her BSN, she made mid 60s. You can make six figures if your willing to put in the time or travel.
