Question

You notice one of the tubes is expired. What would you do?

A. Use a new tube from the front of the shelf
B. Use a new tube from the back of the shelf
C. Use the expired tube regardless of the date
D. Use the tube within 5 days of expiration

Answer 1

When a tube is found to be expired, use a new tube from the front of the shelf to ensure accurate results and safety. Using an expired tube can lead to false outcomes and potential hazards.

Step-by-step explanation:

If you notice that one of the tubes is expired, the appropriate action to take is A. Use a new tube from the front of the shelf. The use of expired materials, especially in a scientific or health-related context, can lead to inaccurate results or be a safety hazard.

Option B, using a new tube from the back of the shelf, may involve using products that are newer but is not always necessary unless the front of the shelf has older stock due to poor stock rotation. Option C, using the expired tube regardless of the date, is not advisable as the chemicals or reagents in the tube may have degraded and may not function as intended.

Option D, using the tube within 5 days of expiration, is also risky as the integrity of the tube's contents cannot be guaranteed even shortly after expiration.
