I have one with very specific instructions
Had a doc berate me for it. I reported him. I know what I want and what I dont. Im content with my decision
I received excellent care when in hospital and rehab.
There are certain things I will not agree to just because a doc wants them. As a patient that is my right. My obligation is to let them know.
I dont necessarily disagree with your premise. A patient should have autonomy. However when I get a crazy statement such as you can to CPR but no meds. Or meds and no CPR. It my personal favorite CPr but no breathing tube then it is incumbent on me to educate the patient as to why its a package deal. I think we all have autonomous authority. However if I am requested to do something that makes no sense or risks outweigh the benefits then my professional autonomy allows me to say no.
