Here's a quotes directly from one of your supplied websites... http://www.blitzresearch.com/site/in....asp?From=site
work under the supervision of a physician. ... In contrast, NPs may work independently
or in collaboration with a physician and must have an RN license before being accepted into an NP educational program.
To me, this sounds like more of a difference than you're suggesting. "
What?! LOL I have not "suggested" anything....
PA's do not "always" work under the supervision of a physician, that is simply not true first of all. Both NP and PA may have their own practices (which I am sure depends on the state). When I go to the doc a lot of times the "doc" I see is a PA. With my daughter (she is 6) goes to her clinic she normally see's the NP.
The only difference I have ever tried to point out is that one practices and is trained in medicine and the other is trained in and practices nursing (and for some people that is a big difference to decide upon....the OP may have no desire be trained in medicine)
I have said over and over it all depends on if you want to practice MEDICINE or NURSING....that is the difference, simple as that (and that is a difference). The OP just wanted to know the difference and those sites give general info about the differences.
Neither are "better" than the other if that is what you are suggesting and I have certainly never suggested that.
