My Mother is 107 and has skilled care 14 hours a day. She lives less than a mile from me and has two lifelines which she can still use. She is now in a hospital bed in her living room for ease of care. We have funding through the state but not enough funds to pay for overnight care. We are there till she goes to sleep and before she wakes up. She sleeps very well and does use her lifeline if needed. I have a durable power of attorney.
What jeannegibbs wrote is true. If you put your mom on hospice they'll take care of everything for you. You call them when the time comes and they come over and go through the necessary procedures. It's very quiet and calm.
The body would then be picked up and transported to the funeral home by the funeral home. Within a day or two, the ME would stop by the funeral home and a death certificate would be issued by him.
