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. Antisocial personality disorder: This disorder is characterized by a disregard for societal rules and the rights of others. Clients with antisocial personality disorder may refuse to follow instructions and demonstrate a lack of respect for rules, indicating a pattern of behavior consistent with this diagnosis. B. Schizotypal personality disorder: Individuals with schizotypal personality disorder typically exhibit eccentric behaviors, social anxiety, and odd beliefs but are not primarily characterized by a blatant disregard for rules or authority. Their behavior is more focused on social discomfort than defiance of rules. C. Narcissistic personality disorder: While clients with narcissistic personality disorder may believe they are above the rules and display entitlement, their behavior is often driven by a need for admiration and self-importance rather than outright defiance of rules. D. Histrionic personality disorder: Individuals with histrionic personality disorder typically seek attention and may be dramatic in their expressions. However, their behaviors are more focused on emotionality and attention-seeking rather than a direct refusal to follow rules or instructions.
