During a psychiatric evaluation, the psychiatric-mental health nurse practitioner conducts a psychiatric review of systems (ROS) in which she reviews common psychiatric symptoms that may not have been elicited in the history of present illness (HPI). Which of the following questions is most likely designed to elicit a response for the symptom "trauma"?

Choice A reason: This question assesses for sleep disorders or narcolepsy, not trauma history. Choice B reason: This question evaluates dissociation or depersonalization, which may occur secondary to trauma but is not a direct trauma screening question. Choice C reason: Asking about the worst event in a person’s life directly elicits a trauma history and can uncover exposure to physical, emotional, or sexual abuse, accidents, or other life-threatening experiences. This question is essential for identifying PTSD risk. Choice D reason: This question screens for phobias or situational anxiety rather than traumatic experiences.
