During inventory, a medical assistant notices medications are missing from the cabinet. To which of the following parties should the assistant report this information?

Pharmaceutical representatives are typically involved in promoting and providing information about their company's products, but they do not have authority over the internal inventory management of a medical facility. Reporting to them would not lead to the resolution of the issue regarding missing medications.

The Food and Drug Administration (FDA) oversees the safety and efficacy of medications but does not handle day-to-day operational issues within healthcare facilities. Reporting missing medications to the FDA would not be appropriate and would likely not result in immediate action regarding the missing items.

The Joint Commission evaluates and accredits healthcare organizations to ensure they meet certain standards. While they set standards for safety and quality, reporting missing medications to them would not result in immediate corrective actions and is not the appropriate channel for inventory management concerns.
