My mother is in the care of hospice. She has not had any food for over a week, and no drink (other than maybe 2-3 syringes of liquid) in about 3-5 days. Today she developed the "death rattle." The nurses have been telling us "2-3 days" for over a week now. She is running fever, her BP is low, (80/45). How long can she go on like this? She is young (45), and has battled cancer for 6 years. I don't want to lose my mom, but I hate watching her suffer.
