agree one hundred percent that we must respect the patient autonomy even when he or she cannot longer make a medical decision. You are a future nurse and you have clear your role as a patient's advocate. However, in this case, I have to disagree with you in some points of the discussion. I was taught that if you have a code on the floor you are working and the family member says to you " he/ she doesn't want to be resuscitated" but there is no DNR, you have to continue CPR or whatever it is. I know is not the same because Brother F is in a mechanical ventilator and doctors state there is no possibility for him to regain consciousness, but the authority of someone acting without a proxy is more limited that someone who does have a health care
