Question 68

The last two digits of an NDC number identify the package size of a drug.

The last two digits of the National Drug Code (NDC) number specify the package size for a particular drug product, providing important information for inventory and dispensing.

A) All of the digits

This option is incorrect because the NDC is composed of three segments, and not all digits are used to indicate the package size. The first five digits and the central four digits serve different purposes related to the drug's manufacturer and product.

B) The first five digits

This option is incorrect as the first five digits of the NDC represent the labeler code, which identifies the manufacturer or distributor of the drug, not the package size.

C) The last two digits

This option is correct because the last two digits of the NDC specifically denote the package size of the drug, making it a critical piece of information for understanding the product's presentation.

D) The central four digits

This option is incorrect as the central four digits of the NDC indicate the specific drug formulation, strength, and dosage form, rather than the package size.

Conclusion

The correct answer is C, as the last two digits of the NDC number are specifically designated to convey the package size of a drug, which is vital for accurate dispensing and inventory management. The other options fail to correctly identify the role of the respective segments of the NDC, thereby underscoring the importance of precise classification in pharmaceutical labeling.
