Task: Answer Verification
Input (English): Question: Do physicians have a responsibility to provide futile or unreasonable care if a patient or family insists?
Answer: Although the issue of physician refusal of requested care has not been resolved by case law or legal statute, it is supported by compelling ethical principles. Physicians are not ethically required to provide futile or unreasonable care, especially to patients who are brain dead, vegetative, critically or terminally ill with little chance of recovery, and unlikely to benefit from cardiopulmonary resuscitation.
Output (English): no
