Some of the posts in this thread seem pretty confrontative on the OP, but maybe its just because smoking is a touchy subject and I just woke up to my maintenance guys in the apartment. Meh anyway.
1. Check with LTC policy.
a. Can patients leave the facility. What is the policy?
b. Don't be afraid to ask your instructors/the staff, in a polite nature, how they handle the situation.
2. Is the patient under a HPOA, some families might have POA and be concerned for their family members future health. Being in a nursing home doesn't always mean you are on the brink of death, and being a cardiac nurse I can vouch that it's never too early to quit, or to have your family care enough to try and help you.
3. Is the person on oxygen? If so then I wouldn't take her out at all, because her head might start on fire!
