Which activity is NOT a duty of a pharmacy support person?

A pharmacy support person plays a crucial role in assisting the operations of a pharmacy, but their responsibilities are typically limited to specific tasks that do not involve direct control over the business aspects of pharmacy practice. One clear example of a duty that falls outside the scope of a pharmacy support person's duties is the responsibility for affecting pharmacy pricing strategies. This role is usually reserved for management or personnel with specific expertise in business and pricing policies, as it requires a deep understanding of market dynamics, regulatory requirements, and financial implications.

In contrast, receiving patient requests for refills, processing prescriptions for controlled substances, and preparing deliveries are activities that can be performed by a pharmacy support person. These tasks involve direct interaction with patients and the day-to-day operational aspects of the pharmacy, which align with the support person's role in facilitating pharmacy services without engaging in high-level business decisions.

Thus, since affecting pharmacy pricing strategies goes beyond the operational support and customer service roles assigned to pharmacy support persons, it is correctly identified as an activity that is not part of their duties.
