A 92-year-old man with Alzheimer's disease has been admitted to the hospital with aspiration pneumonia. He is on a ventilator and has a nasogastric tube in place. He does not have the capacity to understand his medial condition. You find a living will in an old chart that says "No heroic measures," "I want to be DNR," and "I wish to be kept comfortable." There is no proxy and there is no family available with whom you can discuss the matter. He has no private physician with whom you can discuss the case.
What should you do regarding the ventilator and tube feeding?
a. Continue both for now.
b. Remove the ventilator and the tube feeding.
c. Remove the nasogastric tube but continue the ventilator.
d. Seek a court-appointed guardian.
e. Decide what you think is best for the patient.
