People do realize it was an MD that started the NP profession, right?
I am in NP school right now and have been a nurse for about 18 months. Last month, I saved a patient's life by catching an error in prescribing that a doctor and pharmacist both missed until I caught it. Both have more years of experience than the amount of years I've been alive.
I have come to view the health professions in a "you either have it, or you don't" manner. I may be "only" an RN, and "only" will be an NP, but I read the NEJM and read biochem, biophysics, and molecular genetics in my spare time. Not only that, I don't think those med students on that forum realize what nursing education is like and go by things such as course names to determine what we learn. At the undergraduate level, student nurses are learning diseases processes, pharmacology, etc. As a new grad RN, I had to help residents with prescribing and how to treat a patient because they didn't know what to order. Education is one thing; knowing how to apply it is a completely different world. I've met great NPs, PAs, and MDs and I have no problem at all with a PA being my PCP as she's the only one to catch a missed diagnosis that several MDs missed.
