PTCB Certified Pharmacy Technician (PTCE)Patient Safety and Quality AssuranceHard

A pharmacy technician is assisting with the annual inventory count for controlled substances. They discover a discrepancy where the physical count of a Schedule II medication (e.g., oxycodone) does not match the perpetual inventory record. What is the MOST appropriate next action?

  1. APlace a 'Do Not Use' tag on the medication and set it aside.
  2. BAdjust the perpetual inventory record to match the physical count immediately.
  3. CConduct a re-count of the medication and review dispensing records for reconciliation.
  4. DNotify the local law enforcement agency of the discrepancy.
Show answer & explanation

Correct answer: C. Conduct a re-count of the medication and review dispensing records for reconciliation.

A discrepancy in controlled substance inventory, especially Schedule II, requires immediate and thorough investigation. The first step is to re-count and meticulously reconcile records (dispensing, receiving, returns) to identify the source of the discrepancy before reporting to authorities, if necessary.

Why the other options are wrong

  • A. While securing the medication is important, the immediate priority is investigation and reconciliation, not just tagging and setting aside.
  • B. Adjusting records without investigation is inappropriate and could mask theft or significant errors.
  • D. Reporting to law enforcement is required if a significant loss is confirmed after investigation, but not as the immediate first step upon discovering a potential discrepancy.

Controlled Substance Discrepancy Protocol

A controlled substance discrepancy requires immediate re-counting, thorough reconciliation of all related records, and investigation to determine the cause before reporting to regulatory authorities if a significant loss is confirmed.

  • Applies to all controlled substance schedules.
  • Prioritizes investigation and reconciliation.
  • Reporting to DEA/state boards is required for significant losses.

Memory trick: Count, reconcile, investigate, then report if loss is great.
