Which of the following statements about prescriber registrations is correct?

All prescribers must register with the DEA if they intend to prescribe controlled substances. This registration is a legal requirement that ensures prescribers are authorized to handle medications that are classified under controlled substance schedules. The DEA registration process helps maintain oversight and compliance with federal laws governing controlled substances, thereby enhancing patient safety and minimizing the potential for abuse or misappropriation.

In contrast, the other options do not accurately reflect the requirements set forth by regulatory bodies. For instance, it's not solely prescribers or only pharmacies that bear the responsibility of registration; rather, both prescribers and pharmacies are required to register with their respective state and federal authorities depending on their scope of practice and operations. Hospitals also have their own registration requirements and may need a separate DEA registration, particularly if they have practitioners who prescribe controlled substances. Hence, the requirement for prescribers to register with the DEA is a critical aspect of pharmacy jurisprudence in ensuring compliance with the law.
