If an ampule is pre-scored, what distinguishing feature will it typically have?

When an ampule is pre-scored, it typically features a colored stripe around the neck. This stripe is designed to indicate that the ampule has been specifically treated to facilitate easier opening. The scoring process creates a weakened area, allowing the neck to break cleanly without excessive force. The colored stripe serves as a visual cue for healthcare professionals, helping them quickly identify that the ampule is pre-scored and can be handled safely, minimizing the risk of injury.

The other options do not accurately represent the standard features of a pre-scored ampule. For example, a red dot, the words "pre-scored," or an elongated neck are not commonly used indicators for the pre-scoring feature.
