"Nurses have always known 'as much if not more than the doctor'....and to be honest, I'd feel safer in a nurse's hands than a doctor's, because all day long they are dealing with patients at ground level, having far more experience and expertise to deal with a thousand different problems."

Yes, Lizzie and they got that knowledge while obtaining their degrees...

As for "changing beds, helping patients, etc" that work hasn't been done by nurses in a long time, at least where I am from. That is the work of CNAs (Certified Nurse's Assistants) or MAs (Medical Assistants) which are still generally 2 year programs and require a "degree" or "certificate".
