He has Stage 3 lung cancer and is in Stage 1 of Alzheimer's. He fell yesterday. He doesn't remember anything other than putting his hands up to catch himself. I'm an only child so everything is on me. I have power of attorney and I'm his Healthcare Representative. I do not want to force him to do something he doesn't want to do. The Home Health Nurse was able to talk him into giving me his vehicle keys but then two weeks later I'm talking to him and he starts yelling at me. That if I'm going to keep his keys then he won't eat. I was going to give him his key back then he falls and doesn't remember anything. So what if he goes out on the middle of the night and has an accident and leaves the scene. I would be sick!! Please give me some suggestions?
