Which of the following is a duty of a licensed pharmacist?

The duty of transferring controlled prescriptions is a responsibility that requires a licensed pharmacist due to the legal and regulatory framework surrounding controlled substances. This task involves significant oversight to ensure compliance with federal and state laws governing the transfer of these medications, which are subject to stricter regulations to prevent misuse and abuse.

Only licensed pharmacists are authorized to perform this function, as they must verify the legitimacy of the prescriptions and ensure that all documentation is handled correctly. This ensures that the transfer occurs within legal parameters and that the patient's safety and the integrity of the pharmacy system are maintained. Other tasks mentioned, such as assisting in prescription data entry, labeling medication, and handling customer service inquiries, can often be performed by pharmacy technicians or support staff under the supervision of a pharmacist, but the transfer of controlled prescriptions specifically mandates the involvement of a licensed pharmacist.
