Which scenario most accurately depicts a posttraumatic stress disorder (PTSD) reaction?

• A. A newly certified EMT becomes extremely nauseated and diaphoretic at the scene of an incident involving grotesque injuries.
• B. An EMT is emotionally exhausted and depressed after a school bus crash involving the death of several children.
• C. An EMT becomes distracted at the scene of a motor vehicle crash involving the same type of car in which a child was previously killed.
• D. An EMT with many years of field experience becomes irritable with her coworkers and experiences headaches and insomnia.

Answer: (C)

PTSD involves exposure to a traumatic event and persistent, distressing symptoms that recur when reminded of the event, lasting longer than a month and interfering with functioning. In this scenario, the EMT encounters a crash involving the same type of car where a child was previously killed, and this cue triggers a distraction at the scene. That reaction reflects reactivity to trauma cues and hyperarousal, illustrating how past trauma can resurface and impair performance in a new but related traumatic situation. The other options describe acute stress responses, grief or burnout, or nonspecific symptoms that don’t clearly show the enduring, cue-triggered reexperiencing and impairment characteristic of PTSD.
