The client diagnosed with obsessive compulsive disorder (OCD) is likely to present with which nursing assessment finding?

Choice A reason: Responding to the client's inquiry with "I don't know" and redirecting entirely to the healthcare provider without offering any explanation is a missed nursing educational opportunity and reflects a lack of clinical preparedness. While it is always appropriate for nurses to encourage clients to speak with their prescribing providers, it is within the scope of nursing practice to provide accurate pharmacological education about prescribed medications. Carbamazepine is a well-established anticonvulsant and mood stabilizer with a known clinical role in secondary mania and lithium-refractory cases. Refusing to explain the rationale for its use does not support client autonomy, informed consent, or therapeutic communication.

Choice B reason: This response directly and accurately addresses the client's clinical situation by explaining the pharmacological rationale for choosing carbamazepine over lithium. Carbamazepine (an anticonvulsant that inhibits sodium channel activity and modulates glutamate neurotransmission) is indicated as an alternative mood stabilizer for clients whose mania is secondary to a medical condition such as epilepsy, brain tumor, thyroid disorders, or other organic etiologies, as well as for clients with bipolar disorder who have demonstrated inadequate response to lithium therapy. This explanation validates the client's question, provides accurate clinical information, promotes understanding and adherence, and exemplifies patient-centered therapeutic communication.

Choice C reason: Responding with "You will be fine taking this drug, so don't worry" offers false reassurance and avoids providing the clinically meaningful explanation the client is seeking. This type of response dismisses the client's valid concern and does not equip them with the information needed to understand or accept their treatment. False reassurance can also erode trust if the client subsequently experiences adverse effects. Evidence-based nursing communication standards emphasize honest, accurate, and informative responses to patient inquiries rather than reassurances that minimize or dismiss legitimate questions about medication management.

Choice D reason: Vaguely stating that "this drug may be preferred by your health care provider for many reasons" provides no clinically useful information and avoids directly answering the client's specific question. This response is evasive and does not fulfill the nurse's educational responsibility. The client is asking a specific question about why carbamazepine was chosen instead of lithium for their particular medical condition, and they deserve a transparent, informed, and medically accurate response. Providing vague explanations rather than evidence-based patient education fails to support informed decision-making and therapeutic engagement.

Choice A reason: Trusting behaviors are not characteristic of schizotypal personality disorder. According to the DSM-5, schizotypal personality disorder is defined by a pervasive pattern of social and interpersonal deficits, including marked discomfort with and reduced capacity for close relationships, as well as cognitive and perceptual distortions and eccentric behaviors. Individuals with this disorder typically exhibit pervasive suspiciousness and paranoid ideation in social situations, making trust difficult to establish or maintain. Describing trusting behavior as a characteristic of this disorder is clinically inaccurate.

Choice B reason: Dependency needs are a hallmark feature of dependent personality disorder (DPD), not schizotypal personality disorder. Clients with DPD exhibit excessive reliance on others for emotional support, difficulty making independent decisions, and fear of abandonment. In contrast, individuals with schizotypal personality disorder tend toward social isolation, interpersonal aloofness, and discomfort in close relationships, which is nearly the opposite of the dependent interpersonal style. Conflating these 2 disorders reflects a misclassification of personality disorder subtypes.

Choice C reason: Paranoid thoughts are a well-established and diagnostically significant characteristic of schizotypal personality disorder as defined by the DSM-5. During social situations, affected clients may experience suspiciousness and paranoid ideation, including transient, stress-related paranoid thoughts or ideas of reference — the belief that events in the environment have special personal significance. These cognitive distortions emerge in social contexts and contribute to the social withdrawal and discomfort that characterize the disorder. This is distinct from frank psychosis, as the paranoid thoughts in schizotypal personality disorder are generally not of delusional intensity.

Choice D reason: Perfectionism is a core feature of obsessive-compulsive personality disorder (OCPD), which is characterized by a pervasive preoccupation with orderliness, perfectionism, and mental and interpersonal control. OCPD is categorized under Cluster C personality disorders, whereas schizotypal personality disorder falls within Cluster A. The clinical features of schizotypal personality disorder center on odd beliefs, magical thinking, unusual perceptual experiences, social anxiety, and paranoia, not perfectionism or need for control. Attributing perfectionism to schizotypal personality disorder conflates 2 diagnostically distinct conditions.
