This episode unpacks the complexities of personality and impulse control disorders, beginning with their core characteristics of inflexible behaviors and impaired impulse control. We’ll emphasize the nursing priority of assessing self-harm and suicide risk, with focused discussions on Borderline Personality Disorder (BPD)—noted for emotional dysregulation and self-damaging behaviors—and Antisocial Personality Disorder (ASPD), marked by disregard for others and lack of empathy. We also touch on other personality disorders, reviewing key nursing assessments, interventions, and therapeutic approaches, including Dialectical Behavior Therapy (DBT) for BPD. This lecture equips nurses with the knowledge and strategies needed to care for this vulnerable patient population.
