Which of the following can pharmacy clerks not do?

Pharmacy clerks play a vital support role in a pharmacy, but their functions are limited in terms of direct interactions involving prescription medications. The correct response indicates that pharmacy clerks are not authorized to receive new prescriptions or refills over the phone.

Receiving new prescriptions typically requires a licensed pharmacist to ensure the proper validation of the prescription, assess appropriateness for the patient, check for potential drug interactions, and maintain legal compliance. This process demands professional judgment that is beyond the scope of a clerk's responsibilities.

Similarly, taking refill requests over the phone involves assessing the appropriateness of the refill, checking the patient’s record, and evaluating any changes in their medication regimen. Only licensed personnel can make these determinations to ensure patient safety and legal compliance with pharmacy regulations.

Therefore, the correct choice represents clear boundaries regarding the tasks that pharmacy clerks can undertake, emphasizing that certain functions must be reserved for licensed pharmacists.
