The informed consent of the person authorized under this chapter to make a health care decision shall, for all purposes, be deemed the informed consent of the incapacitated person. The person has the same right as does the incapacitated person to receive information relevant to the proposed health care, and to receive, review, and consent to the disclosure of medical records. Disclosure of information regarding contemplated health care to a person authorized to make a health care decision for an incapacitated person is not a waiver of any evidentiary privilege or of a right to assert confidentiality.
