Which term refers to the record of controlled substances usage?

• A. Inventory Log
• B. Sign-in/Sign-out Log
• C. Controlled Substances Ledger
• D. Usage Record

Answer: (B)

Accountability for controlled substances is maintained through a sign-in/sign-out log. This record specifically documents each instance a controlled substance is removed and later returned or used, capturing who took it, when, and in what amount. That creates a traceable, auditable trail that supports regulatory compliance and helps prevent diversion, while also ensuring appropriate patient care by linking doses to the person responsible and the exact time of administration.

Other records, like an inventory log, focus on stock levels rather than who accessed them; a controlled substances ledger is more about overall transactions and totals; a general usage record can be vague and not tied to the sign-out process. The sign-in/sign-out log is the best fit because it directly tracks usage by individual and time, providing the clear chain of custody required in controlled substances management.
