Following health and safety practices relates to which competency?

The choice regarding practicing good housekeeping is the correct answer because it directly addresses the importance of maintaining a clean and safe environment in a pharmacy setting. Good housekeeping practices help to minimize hazards, reduce the risk of contamination, and ensure that both pharmacy staff and patients are protected. This includes keeping work areas organized, storing medications properly, and ensuring that surfaces are disinfected regularly, which are all essential to uphold health and safety standards.

In contrast, the other options pertain to different competencies. Using pharmaceutical calculation techniques and terminologies focuses on the mathematical and language aspects of pharmacy work, which are vital for correct dispensing but don't directly relate to health and safety management. Performing computer operations involves handling pharmacy software and data management systems, and while important, it is more about technical proficiency. Monitoring the supply and inventory of pharmaceutical products is crucial for operational efficiency but is primarily concerned with stock management rather than health and safety practices. Therefore, practicing good housekeeping distinctly relates to ensuring compliance with health and safety protocols in a pharmacy environment.
