B) 75%
C) 50%
D) 25%

Answer 1

The beyond-use date is typically determined by taking 50% of the remaining expiration date or 6 months, whichever is less.

Step-by-step explanation:

The beyond-use date for a pharmaceutical product is determined by taking either a percentage of the remaining expiration date or 6 months, whichever is less. This concept is similar to the concept of a half-life used in the field of chemistry, where it refers to the amount of time it takes for half of a substance to decay or change. In the context of a beyond-use date, the percentage of the remaining expiration date is typically 50%, which means half of the remaining expiration date or 6 months, whichever is less, would be used. Therefore, the correct answer to the student's question is: C) 50%.
