Who knows. They haven't been very active pursuing this, but it does mostly depend on the state, not on who created what. Agree that PAs are usually more suited to surgical work. As I understand it NPs usually need to undertake additional training to assist in the OR. True that NPs are a bit more specialized in training (roughly specialized programs versus fully generalist NP programs), but how much this matters seems to vary. I have certainly seen FNPs working in the acute care setting.
