(a) A patient advocate shall act in accordance with the standards of care applicable to fiduciaries in exercising his or her powers.

(c) A patient advocate shall not exercise powers concerning the patient's care, custody, and medical or mental health treatment that the patient, if the patient were able to participate in the decision, could not have exercised on his or her own behalf.

(d) The designation cannot be used to make a medical treatment decision to withhold or withdraw treatment from a patient who is pregnant that would result in the pregnant patient's death.

(e) A patient advocate may make a decision to withhold or withdraw treatment that would allow a patient to die only if the patient has expressed in a clear and convincing manner that the patient advocate is authorized to make such a decision, and that the patient acknowledges that such a decision could or would allow the patient's death.

(f) A patient advocate may choose to have the patient placed under hospice care.

(g) A patient advocate under this section shall not delegate his or her powers to another individual without prior authorization by the patient.
