My Dad is on hospice at home for cc.  He is becoming increasingly paranoid, yelling & swearing about things;  My sister is with him now, I will be going at the end of the week.  His new take today was to call an ambulance and wait outside of a hospital until he gets a liver transplant.  He has a large tumor on the liver with several small ones.  Chemo did not shrink the tumor, so he would not be eligible.   He is also talking about other things that will not happen and if not agreed with he becomes agitated.  Any suggestions on how to deal with this?
