Final answer:
The actual expiration date of a drug with an expiration label of 06/16 is June 30th, 2016, as it expires on the last day of the mentioned month.
Step-by-step explanation:
If a drug's expiration date reads 06/16, the interpretation of this date format generally indicates that the drug is considered safe and effective if used before the end of the month listed. Therefore, the actual expiration date would be the last day of that month. In this case, June 30th, 2016 is the correct answer. Pharmaceutical products typically expire on the last day of the stated month to ensure that users know they can use the product safely throughout the entire month. It's vital to follow the expiration date strictly for safety reasons, as the efficacy and safety of medications can decline after their expiration dates.
