Which two logs are required for DEA controlled substances?

• A. Purchase log and disposal log
• B. Usage log and inventory log
• C. Calibration log and audit log
• D. Temperature log and humidity log

Answer: (B)

Accountability and traceability of controlled substances rely on clear records of both how much is on hand and how it is used. The two logs you must maintain are a usage log and an inventory log. The usage log captures every time a controlled substance is administered or dispensed to a patient, including date and time, patient identification, amount given, and who administered it. This creates a precise, auditable trail of consumption that helps prevent misuse, theft, and dosing errors. The inventory log monitors the actual stock on hand, recording receipts, transfers, and disposals so the physical count always reconciles with recorded transactions. Together, these logs ensure that every unit can be traced from purchase through to administration, supporting regulatory compliance and security. Other options touch on important aspects of recordkeeping in different contexts—purchasing/disposal logs relate to acquisitions and final disposition, calibration/audit logs are about equipment/process controls, and temperature/humidity logs concern storage conditions. They don’t directly establish the ongoing usage and stock accountability required for controlled substances.
