Final answer:
The term 'C3-5 prescriptions' pertains to medications under schedules 3-5 controlled substances, with partial fills allowed as long as the total prescribed quantity is dispensed within six months.
Step-by-step explanation:
The question regarding the limit for partial fills for C3-5 prescriptions seems to be a mix-up. The provided scenario is about a quality control chemist at a pharmaceutical company who is verifying the accuracy and precision of machines dispensing cough syrup. However, the term 'C3-5 prescriptions' refers to medications that fall under the schedules 3, 4, or 5 controlled substances according to the DEA classification in the United States. The term 'partial fills' typically relates to the dispensing of these controlled substances in portions over a period, rather than as a whole at one time. The exact limit for partial fills can vary, but in general, for C3-5 prescriptions, partial filling is allowed as long as the total quantity prescribed is dispensed within six months of the prescription date.
