You are entitled to your opinion, but you are wrong on a few key points. How do they say it? You don't know what you don't know?â€.
Training is only a tiny portion of becoming an advanced clinician. PA's are presumed to hit the ground runningâ€, because their schooling is more focused. I agree that a lot of NP education is garbage nursing stuff. I used to find LPN's to be better nurses early on, and some became better than RN's overall because they were very task-oriented. But they had limits in their scope of practice that required an RN to do some of their work, and ultimately pushed them out of almost every hospital I know of. Why choose a degree that has more limits than the alternate choice?
PA's are having the same job issues as NP's, although they have still managed to hang on to a small pay advantage in most areas. In Florida, there is a shortage of jobs for both. Many postings are for NP/PA, but a wise physician will tell you they prefer an NP because of the autonomy.
As for changing specialties, NP's can work wherever their scope allows. Primarily, adult (now adult-gerontology), or FNP (all ages). I happen to be an adult ARNP, and have found absolutely zero limit as far as changing or considering changing specialties. The only limit I have is not treating under 18, which is fine by me. But I could add a post-master's certificate for family NP if I wanted it.
In the real world, I just trained with a PA, and interviewed another PA who will be making exactly the same as the NP's in our company. I know many NP's who are functioning in roles that a PA could not do. But I don't know any PA's functioning in a role that an NP couldn't do.
