My 91 dad is near the end of his life. A district nurse called this evening and said that they will provide care to my dad but they need to tell him the truth about his condition and get him to sign some papers to say he understands. My mum and me don't want them to do this. We don't think my dad wants to know. We think this will just really upset him and hasten the end. My mum managed to stop the district nurse saying anything this evening but she said she's coming back tomorrow. I don't know what to do. My mum expects me to call her back with a solution. Any advice?
