Pharmacy Technician Certification Board Practice Exam Practice Question

Correct Answer: B

Rationale: The difference in the last two digits of the NDCs (National Drug Codes) indicates the bottle size. In this case, "03" and "01" represent different packaging sizes for the same medication.

Option A, the expiration date, is not reflected in the NDC structure. Expiration dates are separate from the NDC numbering system.

Option C, the dosage form, is typically indicated by the middle segment of the NDC, not the last two digits.

Option D, the manufacturer, is identified by the first segment of the NDC, which remains unchanged in both examples. Thus, the last two digits specifically denote variations in bottle size.
