Thanks for inputs everyone. While I realize the importance of needing to think through it well before getting into, I also am encouraged by NPs who enjoy what they do now, though he/she did not like bedside RN job necessarily.
It is true of what many of you said. NP and RN is clearly, VERY VERY different role. One is a provider, and the other is not. I think in that alone, the whole ball game changes. I won't be spending time drawing up dilaudid and priming 50cc bag of NS with phenergan or 50 mg benadryl because patient says "Oh, I have to have that with my dilaudid because of _____," or running around to bring somebody warm blanket or a sandwich (nothing wrong with that innately, just not what I want to do in my 40s) @Armanix asked if I won't find demanding patients and RNs paging, etc stressful. No, because I will be calling shots, and I have right to say "NO" if I find it consistent with my practice principals and clinical expertise. From my experience, patients tend to act in whatsoever manner they please with RNs and ancillary practitioners (LVN, CNA, RT, radiology tech, phlebotomist, etc) but in general, they respect providers, including NPs and PAs, because they are seen as "oh, this guy/gal can diagnose and prescribe, and can order stuff." I do not want to work in the hospital anyway (aka Cronies. INC), so if I can afford it, I would work in clinic or under specialist to learn the ropes, so hospital administration is hopefully not something I encounter. Yes, clinics or urgent cares, and wherever else can have corrupt people, but that's comparing hundreds of them to a couple. I don't think there's anything wrong with RNs calling me to ask what to do. That's what providers are for, and if position of leadership, challenges and decision-making is merely annoying, I don't see why someone would want to be a provider in the first place.
Like many said, being RN and NP is very different thing. In my notion, one works and works and works, while the other gets to think, use the brain, diagnose, prescribe, order, etc and perform in similar role as a doctor, though not in completely the same role of course. I am not saying that RNs can't use their brains, but the minute and de-humaning works (like realizing that you graduated Bachelors and is literally spreading cheeks to wipe a rectum), delivery-boying, errand-running, hotel-resorting and restaurant-servicing, are far different than working as provider. Those are just my thoughts.
