The lines we walk in this industry are so fine as to be invisible.
If a resident wants to do something, but it's going to hurt them, how do we decide what's right? If it's not illegal or immoral, but it could result in injury, hospitalization, or death, do we have the right to stop them?
Smoking is a big one. If having a cigarette can result in respiratory arrest, can we forbid them from having one? Isn't it their right to smoke if they want to? Do we have the right to limit them or forbid them from smoking?
If the resident refuses a shower, but desperately needs one, do we have the right to force them in there and hose them off? If we don't, and they suffer from skin breakdown, is it then our fault because we respected their wishes?
How do we know whether what we're doing is abuse or just saving them from themselves?
