When a patient picks up a prescription, all of the following should be done by the technician, except ____.

Prescriptions are kept on file by the pharmacy. The only time a prescription is returned to the patient is when it is not filled by the pharmacy.
Note: Be careful on questions like these. You'll need to use context because the word "prescription" is widely used to refer to the paper/digital order, as well as to the filled medication. In this answer, you know it refers to the order since it says "return" to the patient.
