Which term refers to a record-keeping system for tracking usage and wastage of controlled substances?

• A. Medication Storage
• B. Perpetual Log
• C. Tamperproof Tag
• D. Narcotic Prescription

Answer: (B)

Tracking usage and wastage of controlled substances requires a continuous record-keeping system that stays up to date with every transaction. The term that fits this best is a perpetual log, because it records each receipt, each administration, and any disposal or loss of the substance in real time. This ongoing ledger allows instant reconciliation between what was dispensed and what was consumed or discarded, helps detect discrepancies, and supports regulatory compliance and security against diversion. Medication Storage describes where meds are kept, not the ongoing transaction record. A tamperproof tag relates to securing containers, not documenting usage. A narcotic prescription refers to the order itself, not the inventory and disposal tracking.
