That is what "hospice" does. They administer morphine--to make the patient comfortable while they are dying. They will tell you to the day and hour how long your family member will live, because they know exactly how long it takes for the morphine to kill.
I had a family member who just died a couple of weeks ago. The hospice workers came to the house. They told me this themselves.
This is the first I've heard of this in Terri's case.
From what I have read everyone states that she is in no pain and will not feel any pain when she is starved to death because of her brain damage not because they are giving her morphine.
