Disregard it — patients cannot refuse future treatment in advance.

Review the PAD with the patient, place it in the medical record, and discuss the clinical implications of the stated preferences. The PMHNP should ensure the patient understands the potential consequences and explore the reasoning behind the preference — while respecting the patient's right to establish these preferences when she has capacity.

Accept the document without discussion — the patient's written preferences override any clinical concerns.

Refuse to treat the patient if she will not agree to accept antipsychotics in the future.
