I just spent a few minutes reading all about Jehovah's Witnesses and what kinds of blood products they will and will not accept. Because I have a patient who needs blood and won't accept any.
"You understand that you need a transfusion."
"And without it, you have a much poorer prognosis."
"We need to talk about your code status, in case something happens. Would you want to be kept alive artificially."
"And you would want us to do whatever we can do to help you."
"Except give you blood."
"So we should intubate, put you on a ventilator, all of that-- some of which may well be avoidable if you would let us actually treat you the way we are recommending."
"So we should do everything. Except give you blood, which would probably help us avoid needing to do these other, more invasive things."
"So do everything, except the easiest and most useful thing we could do."
