I can speak on this topic probably better than most. I'm a doctor, my wife is a nurse. Nursing school is a joke. You can literally get by without knowing shit and get your nursing degree. To get your RN, most classes aren't even medical related, half the work you do is just social work stuff and the social side of medicine, having almost nothing to do with actual treatments and diagnosis. In med school, not only is the degree of difficulty of classes exponentially harder, but you have to go through several board exams, then get into residency, then more board exams before you practice.
Nurses are good at their job, which is executing orders. Through seeing and doing, they can catch on to alot of things like diagnosis and treatment. But at the end of the day, they don't understand the depth of problems beyond a superficial level. Even as a first year resident, after about 6 months or so, I knew more than nurses that had 20+ years of experience under their belts. As a 2nd and 3rd year resident, I'd go to rapid responses with the RRT nurse, who is critical care trained and one of the better nurses, and they'd still be dead wrong with alot of their assessments and try to argue with me about things.
Yea healthcare wouldnt run without nurses. But the hospital also wouldn't run without the janitor and cleaning services.
And IMO, Nurse Practitioner is just a dangerous profession. Anyone who sees one, I would tell them to go see a real doctor.
And all of this that I just said, my wife would agree 100%. We've had several conversations about it.
