A client with borderline personality disorder (BPD) tells one nurse: 'You're the only one who understands me — the others are terrible nurses.' What interpersonal dynamic is this and how should the nurse respond?

SPLITTING IN BORDERLINE PERSONALITY DISORDER: DEFINITION: Seeing people as entirely good or entirely bad — unable to hold the ambivalent complexity that everyone is both; 'You're wonderful, everyone else is terrible'; RECOGNITION: Is a classic BPD interpersonal pattern; the 'wonderful' nurse gets idealized; the 'bad' nurses get devalued; this can create division in nursing teams if not recognized; THERAPEUTIC RESPONSE: Acknowledge feelings without reinforcing: 'I'm glad you feel heard. I also want you to know that all of your nurses care about you and work as a team'; WHAT NOT TO DO: Agree that other nurses are bad; become a 'special' nurse who is different from the team; allow special treatment that breaks unit rules; TEAM COMMUNICATION: CRITICAL — document the pattern; hold a team meeting to ensure all staff respond consistently; inconsistent responses allow the splitting to continue; LIMITS AND CONSISTENCY: Clear, compassionate consistent limits from all team members is the most therapeutic approach; BPD clients benefit from predictability and consistency.
