Nurse practitioners might have a doctorate in nursing, but calling them doctors is extremely misleading. They function is a very similar capacity to PAs, although PAs often have more capabilities.

All of the levels mentioned here have their places, but calling any of them "doctors" who don't have an MBBS, MD, DO, or equivalent physician-level degree is inappropriate.

They do not require a doctorate in nursing -- it's a masters degree. ("MSN-NP")

Yeah, hence the "might"; some programs are doctorate degrees
