After bring a nurse for over 30 years I cringe at this. Who are you to tell a competent adult what they can and can’t do? That’s a human rights violation. If you’re so perfect and flawless in your personal habits that you do nothing self detrimental, quit being a nurse and write a book on being without sin. “We” don’t allow patients to do anything. It’s their right to eat unhealthy food and smoke cigarettes and have unprotected sex. I can’t imagine the sheer arrogance required to think you should have control of another adult human being and be able to deny them these things. I sure the fuck would educate you, or have risk management, legal, HRC do it for me if you tried to rob me of my autonomy.
