A client's medical record contains an advance directive stating 'DNR/DNI — do not resuscitate, do not intubate.' The client is found unresponsive on the unit. What should the nurse do?

ADVANCE DIRECTIVE AND DNR ORDERS: LEGAL STATUS: A valid advance directive and physician's do-not-resuscitate order is a LEGAL DOCUMENT that must be honoured; CPR against a DNR order is assault; VALIDITY CHECK: Is the document current? Is it in the medical record? Is there a corresponding physician's order (the advance directive alone is not sufficient — a physician's order translating it to a specific DNR order is usually required in hospitals); DNR ≠ NO CARE: DNR means no CPR — all other comfort care, pain management, dignity care continue; NURSE'S ROLE: Know the DNR/advance directive status of all patients before a crisis; ensure the order is properly documented; follow the order; notify the team; support the family; DISCREPANCIES: If family members are demanding resuscitation despite a valid DNR — this is a care conference/ethics consultation situation; the physician and team should be contacted; the DNR order is valid; DOCUMENTATION: Time of death; assessment; notifications; comfort measures provided.
