A. Physician's Order Sheet: While the physician orders narcotics, administration is not documented here.

B. Narcotic Administration Sheet: The Narcotic Administration Sheet is specifically for controlled substances, ensuring proper tracking and preventing misuse.

C. Care Plan: The care plan outlines patient goals and interventions, not medication administration.

D. MAR (Medication Administration Record) and Narcotic Administration Sheet: The MAR (Medication Administration Record) documents all medications given to the patient. The Narcotic Administration Sheet is required for controlled substances to comply with regulations.
