What should a pharmacy technician do if they notice a discrepancy in medication stock levels?

When a pharmacy technician notices a discrepancy in medication stock levels, reporting it to a supervisor is the appropriate action to take. This is crucial because discrepancies could indicate various issues, such as theft, loss, or errors in inventory management. By informing a supervisor, the technician ensures the problem is addressed properly and efficiently, potentially leading to an investigation to determine the cause of the discrepancy.

Additionally, a supervisor typically has the authority to take necessary action, such as adjusting ordering processes or conducting audits. This helps maintain the integrity of the pharmacy's inventory system and ensures that patient safety is prioritized.

The other options, like ignoring the discrepancy, adjusting stock levels themselves, or changing the minimum/maximum levels, could lead to further issues, such as medication shortages or misuse of inventory control procedures. Therefore, reporting to a supervisor is the most responsible and appropriate step in this situation.
