40. Which of the following auxiliary labels would be most appropriate to affix to a bottle of cephalexin oral suspension after reconstitution?

Answer: D

Explanation:

Keep refrigerated; Discard after 14 days

Cephalexin oral suspension, once reconstituted, should be kept refrigerated and discarded after 14 days to ensure its efficacy and safety. This labeling helps maintain the medication's stability and prevents potential degradation.

A) Protect from light; Discard after 7 days

This option is incorrect because cephalexin oral suspension does not specifically require protection from light, and the discard timeframe of 7 days is not suitable. The correct duration for safe use after reconstitution is 14 days.

B) Protect from light; Discard after 14 days

While the discard timeframe of 14 days is accurate, this option incorrectly suggests that the suspension needs protection from light. In practice, cephalexin does not have light sensitivity issues that necessitate this precaution.

C) Keep refrigerated; Discard after 7 days

This choice is incorrect because, although keeping refrigerated is appropriate, the discard timeline of 7 days is insufficient. The correct guideline specifies a 14-day period for safe use after reconstitution.

D) Keep refrigerated; Discard after 14 days

This option is correct as it accurately reflects the storage and expiration instructions for reconstituted cephalexin oral suspension. Keeping the medication refrigerated helps maintain its stability, while the 14-day discard period ensures safety.

Conclusion

The correct option is D, as it aligns with the recommended storage and usage guidelines for cephalexin oral suspension after reconstitution. Options A, B, and C fail to meet the necessary criteria for proper handling and safety, confirming D as the definitive choice.
