During a psychiatric evaluation, the psychiatric-mental health nurse practitioner conducts a psychiatric review of systems (ROS) in which he 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 system "anxiety"?

Choice A reason: This question targets somatic concerns and health anxiety, not generalized anxiety or worry about multiple domains. Choice B reason: This question assesses depersonalization or derealization symptoms rather than anxiety. Choice C reason: This is correct. Asking about persistent worry over several months directly targets generalized anxiety symptoms, helping identify excessive worry characteristic of anxiety disorders. Choice D reason: This question is designed to assess manic or hypomanic episodes, as it evaluates periods of decreased need for sleep with elevated mood or energy, not anxiety.
