Question 12

The difference in the bottles is the package size.

The two stock bottles of atenolol differ by their package size, indicated by the last two digits of their NDC numbers. The "-10" signifies a larger package size compared to the "-01," which represents a smaller package size.

A) Package size

This option is correct because the last two digits of the NDC numbers indicate the package size. The "-10" suggests a package containing more units of medication than the "-01," which is consistent with the distinction noted in the question.

B) Dosage

This option is incorrect as both NDC numbers represent the same medication, atenolol, which implies the dosage remains constant across both bottles. The differentiation does not pertain to the dosage but rather to the quantity in each package.

C) Manufacturer

This option is incorrect since both NDC numbers start with the same manufacturer code "00781," indicating they are produced by the same manufacturer. Therefore, there is no distinction in the manufacturer based on the provided NDC numbers.

D) Strength

This option is inaccurate because both NDC numbers correspond to the same strength of atenolol. The strength of the drug is not affected by the package size, which is the actual point of difference.

Conclusion

The correct answer, A) Package size, precisely identifies the distinction between the two bottles as indicated by the unique NDC numbers. All other options fail to recognize that the variations pertain to the amount of product contained in each package rather than dosage, manufacturer, or strength.
