This case study explores the application of the biopsychosocial model in providing nursing care for Matthew, a 30-year-old man diagnosed with borderline personality disorder (BPD). It examines the interplay of biological factors, such as a history of alcohol use disorder and potential genetic predispositions, psychological factors, including past trauma like childhood sexual abuse and self-harm, and social factors, such as the impact of traumatic life events on relationships and mental wellbeing. The nursing interventions proposed include patient education, pharmacological interventions (mood stabilizers, SSRIs, antipsychotics), and therapeutic approaches like cognitive behavioral therapy and psychotherapy to help Matthew manage his emotions, develop distress tolerance, and foster mindfulness. The study emphasizes the importance of addressing Matthew's past trauma and fostering a positive outlook to improve his mental wellbeing. Desklib offers a range of study tools and solved assignments for students.
