If an ampule has been pre-scored, it will have which indication?

An ampule that has been pre-scored typically features a colored stripe around the neck. This visual indicator is designed to help healthcare professionals quickly identify that the ampule is specifically designed for easy breaking. The colored stripe communicates important information about the ampule's usability, signifying that it has been manufactured to allow for a controlled break at the pre-scored line, which minimizes the risk of glass shards and makes it safer and simpler to open.

In the context of pharmaceutical handling, recognizing these indicators allows for efficient and safe preparation of medications. The other options, while they might suggest characteristics of ampules, do not universally indicate that an ampule is pre-scored.
