Here in Florida, they are called Medical Assistants and they can, among other things, give immunizations, draw blood, do a basic EKG (not interpret), take vitals and such. In almost every doctor's office there are either entirely MA's or almost all MA's and one or two "nurses." Yes, the doctors call them nurses, which is against state board policies, that is leading patients to believe they are dealing with "licensed" professionals, when in reality they are only certified. they get paid crappy, like 8-10 an hour. You will hear them, foolishly, saying things like, "I should be a nurse, I basically do what one does anyway." Makes me angry but I bite my tongue, not a rule, but have heard it many times. This seems to be the wave of future office environments, it's all about the bottom line.
