CIS stands for which stress-related term?

• A. Chronic Incident Stress
• B. Central Incident Stress
• C. Critical Internal Stress
• D. Critical Incident Stress

Answer: (D)

Understanding this term means recognizing stress that comes from a specific, high-severity event. Critical Incident Stress is the standard phrase used to describe the acute stress responses that people may experience after a traumatic incident, especially in emergency and trauma situations. The idea is that a particular incident is so serious that it triggers immediate psychological and physiological reactions, which may require support or intervention as part of overall stress management.

The word choices reflect that: "critical" signals the seriousness of the event, "incident" points to a single event or occurrence, and "stress" is the response. The other options don’t fit common usage: Chronic Incident Stress would imply a long-lasting version of stress from an incident, which isn’t the established term; Central Incident Stress and Critical Internal Stress aren’t recognized terms in this context.
