A nurse is caring for a client who describes extreme fear of having or acquiring a disease. The client is also exhibiting behaviors like repeated body checking. The nurse should identify that the client is exhibiting manifestations of which of the following disorders?

Choice A rationale Somatic symptom disorder involves experiencing physical symptoms without a clear medical cause, leading to significant distress or functional impairment. The primary focus is on the physical symptoms themselves, rather than a pervasive fear of acquiring a disease, differentiating it from the client's described extreme fear. This disorder often includes excessive thoughts, feelings, or behaviors related to the somatic symptoms. Choice B rationale Illness anxiety disorder is characterized by a preoccupation with having or acquiring a serious illness, despite the absence of significant somatic symptoms. Individuals exhibit high levels of anxiety about health and frequently engage in excessive health-related behaviors like repeated body checking, which aligns precisely with the client's described manifestations. This anxiety persists even after medical reassurance. Choice C rationale Functional neurological symptom disorder, also known as conversion disorder, involves neurological symptoms like paralysis or blindness that are inconsistent with known neurological conditions. The distress manifests as a loss of function rather than a fear of acquiring disease or repetitive body checking behaviors. The symptoms are not intentionally produced and are thought to be related to psychological factors. Choice D rationale Factitious disorder is characterized by the falsification of physical or psychological signs or symptoms, or induction of injury or disease, associated with identified deception. The motivation for these behaviors is to assume the sick role, not an actual fear of having or acquiring a disease, nor is it merely repeated body checking due to anxiety. This disorder involves intentional deception.
