Which of the following describes a key procedure for controlled substances?

• A. Secure storage, strict access controls, accurate logs, regular inventory reconciliation, and audits
• B. Open shelving with unrestricted access
• C. Only annual checks without logs
• D. No documentation required

Answer: (A)

Key principle: controlled substances require both secure storage and thorough, ongoing documentation to prevent diversion and ensure compliance.

Secure storage means drugs are kept in locked, tamper-evident containers or safes, with access limited to authorized personnel. Strict access controls mean each person who handles these substances is identified and authenticated, reducing the chance of unauthorized use. Accurate logs capture every transaction—receipts, dispenses, transfers, and waste—so quantities can be tracked against the physical stock. Regular inventory reconciliation, including cycle counts and periodic full inventories, helps catch discrepancies quickly and accountability can be assigned. Audits provide independent verification that procedures are being followed and records are complete.

Unrestricted open access, lack of logs, or no documentation would allow or obscure loss or theft and fail to meet safety and regulatory standards, making them inappropriate.
