Q1

A 76-year-old man is brought to the hospital after having a stroke. Head CT is done in the emergency department and shows intracranial hemorrhage. Upon arrival to the ED he is verbally non-responsive and withdraws only to pain. He does not open his eyes. He is transferred to the medical ICU for further management and intubated for airway protection. During his second day in the ICU, his blood pressure is measured as 91/54 mmHg and pulse is 120/min. He is given fluids and antibiotics, but he progresses to renal failure and his mental status deteriorates. The physicians in the ICU ask the patient’s family what his wishes are for end-of-life care. His wife tells the team that she is durable power of attorney for the patient and provides appropriate documentation. She mentions that he did not have a living will, but she believes that he would want care withdrawn in this situation, and therefore asks the team to withdraw care at this point. The patient’s daughter vehemently disagrees and believes it is in the best interest of her father, the patient, to continue all care. Based on this information, what is the best course of action for the physician team?
