(B) This chapter does not authorize the provision of health care to a patient who is unable to consent if the attending physician or other health care professional responsible for the care of the patient has actual knowledge that the health care is contrary to the patient's unambiguous and uncontradicted instructions expressed at a time when the patient was able to consent.
(C) This section does not limit the evidence on which a court may base a determination of a patient's intent in a judicial proceeding.
