There's a PA in my nursing school
class. He's going into nursing for several reasons.
One, as stated earlier, PAs operate on the medical model, he prefers a more patient-oriented appproach.
Two, a PA works under someone else's license-a physician. An NP works under his or her own license.
Three, he wants to travel internationally and go back to Ghana, where NPs are recognized, and since he doesn't have his own license as a PA, he can't practice there.
I haven't heard of the NP market being saturated. Schools
in our area are very actively trying to recruit people into NP practice.
Depending on the state you live in, NPs may or may not have prescriptive authority. Most do have at least limited authority. Here in MD, NPs do not, but I believe PAs do, because of the licensing under a physician.
