As a person who chooses not to smoke, I feel that I am not the one who should be limited in my restaurant choices. It is not good enough to simply "not go to an establishment that allows smoking". I should have the right to go anywhere I want without having to inhale someone else's nasty habit. Since it is the smoker who chooses to pollute their own lungs with a carcinogen then it is they who need to be limited in their choice of establishment and not the other way around. I do expect the government to enforce my right to fresh air.
I think there will always be lazy people in all professions ,including nursing. The RT's work hard and are overloaded, imo, at the hospital I work at. The RT's handle all aspects of ventilator care at our facility including ART lines, bronch assist, and tube placement.
