The nurse is reviewing the different types of personality disorders and recognizes the following fall into the Cluster A Personality Disorders? (Select all that apply)

Choice A reason: Borderline personality disorder is a Cluster B disorder, characterized by emotional instability and impulsivity due to dysfunctional emotional regulation circuits, including the amygdala and prefrontal cortex. It does not belong to Cluster A, which includes eccentric and odd behaviors, making it an incorrect choice for this category. Choice B reason: Avoidant personality disorder is a Cluster C disorder, marked by anxiety and fear of rejection, linked to heightened amygdala sensitivity to social threats. Cluster A disorders involve odd or eccentric traits, not anxiety-driven avoidance, so avoidant personality disorder does not fit the Cluster A category. Choice C reason: Schizotypal personality disorder is a Cluster A disorder, characterized by eccentric behavior, odd beliefs, and perceptual distortions, likely due to subtle brain abnormalities in the frontal and temporal lobes. These traits align with the odd, eccentric nature of Cluster A, making it a correct choice for this category. Choice D reason: Antisocial personality disorder is a Cluster B disorder, involving impulsivity and disregard for others, associated with reduced prefrontal cortex regulation of aggressive impulses. It does not exhibit the eccentric or odd traits of Cluster A, making it an incorrect choice for this personality disorder cluster. Choice E reason: Paranoid personality disorder is a Cluster A disorder, marked by pervasive distrust and suspiciousness, potentially linked to hyperactivity in limbic system structures like the amygdala. Its eccentric and odd presentation fits the Cluster A category, making it a correct choice for inclusion in this group.
