Since my father and step mother were both in hospice (not at the same time) and I was the primary caregiver for my father I do have experience with this. Talk to her. My father and I carefully weighed out all of the options before we (mainly he) decided that enough was enough. He also had a broken femur, bad heart, lymphoma and required around the clock caregiving and we honored his wishes to be at home. The hospice people were wonderful and gave us great training and support. They did everything humanely possible to provide a painfree and dignified death, not to mention respite care, training and support for all of the caregivers. They even provided a chaplin and grief support afterwards.
