My 85 yo sister goes between hospital and nursing home with low blood pressure, low oxygen, bleeding ulcer, arrhythmia. She eats and drinks very little when coaxed and is no longer responding or talking to nurses or on the phone to us. (We cannot be with her because of the virus at this time.) She belongs to a local parish. My brother and I are her nearest relatives and poa for her care. Her doctor today suggested we begin hospice care for her. She never shows improvement, just steady decline. How do we know when to call for a priest, or will her caregivers help us in that decision?
