A nurse on a mental health unit is caring for a client who refuses to follow instructions and states that the unit rules do not apply to them. The nurse should identify that these findings are manifestations of which of the following personality disorders?

A. Schizotypal personality disorder is characterized by eccentric behavior, odd beliefs, and social anxiety, not a blatant disregard for rules or instructions. The client’s defiance and rule-breaking do not align with this disorder. B. Narcissistic personality disorder involves grandiosity, need for admiration, and lack of empathy, but it does not inherently include persistent refusal to follow rules or disregard for authority. The client may challenge others but usually to gain attention or validation rather than consistently violate rules. C. Histrionic personality disorder is characterized by attention-seeking, dramatic behavior, and emotional exaggeration. Defiance of rules is not a primary feature. D. Antisocial personality disorder is correct. antisocial personality disorder is marked by a pattern of disregard for, and violation of, the rights of others, impulsivity, deceitfulness, and failure to conform to social norms or rules. The client’s refusal to follow instructions and claim that unit rules do not apply reflects classic manifestations of antisocial personality traits.
