I am a nursing student in St. Louis, MO. One of my teachers has a PhD in Physiology, one is a PhD RN, and one is an NP. Their scope of practice could not be farther from each other. Dr. *********, PhD in Phys, couldn't prescribe medication if his life depended on it, although he is extremely knowledgeable in that field. Dr. ********, PhD RN, has a terminable degree of PhD, like Dr. *********, but neither are "doctors" in the medical sense. Neither are physicians, either. Dr. ******* is a research nurse. He has experience in the delivery room and in AIDS research. *******, MSN NP, can prescribe medication, because that's what NP's do. She isn't a "doctor", or a physician, she's a nurse. Our school offers a combo DNP/PhD program, whether you have a BSN, or MSN. This would be the ultimate in nursing degrees. You have the "esteemed" PhD, a terminable degree, and you also have the Doctorate in NP, which allows medication prescriptions, as well as the fact that it is not a terminable degree. I know this is years after the original post, but I found this thread to be interesting, and wanted to get my hands dirty as well, lol!
