Pharmacy Technician Certification Exam Practice Questions Practice Question

Correct Answer: D

Rationale: Federal law mandates that a complete inventory of controlled substances must be conducted every two years to ensure accurate tracking and compliance with regulations. This timeframe helps maintain accountability and security in handling these substances.

Option A (Month) is incorrect as monthly inventories are excessive and not required by law. Option B (6 months) is also inaccurate; while some states may have stricter regulations, federal law specifies a two-year interval. Option C (Year) misrepresents the requirement, as annual inventories do not meet federal standards. Therefore, the two-year period is both a legal obligation and a practical measure for effective substance management.
