The nurse is conducting client assessments in an outpatient psychiatric clinic. Which client finding is characteristic of illness anxiety disorder?

Choice A reason: Illogical responses to questions are more characteristic of thought disorders such as schizophrenia, not illness anxiety disorder. Illness anxiety disorder is defined by excessive preoccupation with having or acquiring a serious illness, not disorganized thinking. Choice B reason: Increased talkativeness and pressured speech are hallmark features of mania, not illness anxiety disorder. This presentation reflects mood disturbance rather than health-related anxiety. Choice C reason: Ritual daily breast exams for fear of cancer are characteristic of illness anxiety disorder. Clients with this disorder engage in repetitive health-related behaviors due to persistent fear of serious illness despite medical reassurance. This compulsive checking behavior reflects the anxiety-driven preoccupation with disease. Choice D reason: Poor concentration and slow thought processes are more typical of depressive disorders. While anxiety can impair concentration, the defining feature of illness anxiety disorder is health-related preoccupation, not cognitive slowing.
