A nurse is interviewing a client and suspects that the client may have narcissistic personality disorder. Which client statement would help support the nurse's suspicions?

Choice A reason: The statement "I have a very important position in life; everyone I know wants to be like me" is a clear and direct verbal expression of grandiosity and an inflated sense of self-importance, both of which are cardinal diagnostic features of narcissistic personality disorder as defined in the DSM-5. This statement reflects the client's belief in their own unique superiority and their expectation that others aspire to emulate them, consistent with the NPD criterion of a pervasive pattern of grandiosity in fantasy or behavior. This type of statement, when arising spontaneously in a clinical interview, strongly supports the nurse's clinical suspicion of narcissistic personality disorder. Choice B reason: The belief that a spouse is poisoning the client's food to collect life insurance money is a persecutory delusion, which is a hallmark of paranoid personality disorder or, depending on severity and conviction, of psychotic disorders such as delusional disorder or schizophrenia. Persecutory ideation involves the belief that one is being harmed, threatened, or conspired against by others. This symptom cluster is diagnostic of paranoid pathology rather than narcissistic personality disorder. In NPD, the primary distortion is an overestimation of the self, not a fear of external persecution. Choice C reason: Describing oneself as "always the life of the party" and claiming to be constantly making new friends reflects a sociable, outgoing, and attention-seeking behavioral pattern more consistent with histrionic personality disorder. Histrionic personality disorder is characterized by theatrical behavior, emotional superficiality, and a need to be the center of social attention. While individuals with NPD may also enjoy social admiration, the defining clinical feature is grandiosity and entitlement rather than expressly social engagement and friend-making. The statement in this choice lacks the explicit superiority and entitlement that characterize narcissistic ideation. Choice D reason: The preference for working alone in order to let thoughts wander is more consistent with schizotypal personality disorder or schizoid personality disorder, both of which involve social withdrawal and a preference for solitary activities. Schizoid personality disorder specifically is characterized by a lack of desire for social relationships and emotional detachment, while schizotypal personality disorder may involve magical thinking and eccentric thought patterns. Neither of these presentations involves the grandiosity, sense of entitlement, or need for admiration that define narcissistic personality disorder.
