How does the board protect the public?

The correct choice highlights the critical role that monitoring pharmacy practices plays in protecting public health and safety. Regulatory boards, such as the Board of Pharmacy in Minnesota, are responsible for ensuring that pharmacies and pharmacists adhere to established laws and regulations designed to promote safe dispensing practices, medication management, and adherence to quality standards. By systematically reviewing pharmacy operations, inspecting facilities, and ensuring compliance with licensure requirements, the board safeguards against potential errors, mismanagement, or unsafe practices that could endanger patients.

Regarding the other options, increasing the number of pharmacies does not inherently protect the public if those pharmacies do not maintain safe practices. Enabling pharmacists to raise prices could lead to increased costs for consumers without a corresponding benefit to public safety. Lastly, while restricting the sale of medications can help prevent misuse or abuse, it doesn't encompass the broader scope of how the board monitors and ensures safe practices in all aspects of pharmacy operations. Thus, monitoring pharmacy practices is the most direct way a board can protect public interests.
