## 문제

A nurse is caring for a client with borderline personality disorder who frequently engages in self-harm behaviors and has unstable interpersonal relationships. The client states, "You're the only nurse who understands me. All the others are terrible and don't care about me at all." What is the most therapeutic nursing intervention?

## 보기

1. Set consistent boundaries while acknowledging the client's feelings and redirect focus to therapeutic goals. **✔ 정답**
2. Agree with the client's assessment to build rapport and trust in the therapeutic relationship
3. Immediately confront the client about the inappropriate splitting behavior and demand an apology
4. Avoid the client for the remainder of the shift to prevent reinforcement of the manipulative behavior.

**정답: 1**

## 해설

For borderline personality disorder with splitting, therapeutic intervention involves setting consistent boundaries while validating feelings. Other options may reinforce splitting, damage rapport, or be punitive.

## 심화 해설

Understanding the Client's Statement

The client's statement, "You're the only nurse who understands me. All the others are terrible," is a classic manifestation of splitting, a primitive defense mechanism central to borderline personality disorder (BPD). In splitting, an individual is unable to integrate the positive and negative qualities of self and others into a cohesive whole. Instead, people and experiences are categorized as all-good or all-bad. This is not a conscious manipulation but a reflection of the intense emotional dysregulation and relational distress described in the diagnostic construct of BPD [3]. The client's unstable interpersonal relationships are a direct consequence of this dichotomous thinking.

Analyzing the Therapeutic Options

The goal of a therapeutic intervention is to provide a corrective relational experience that models healthy integration and maintains professional boundaries, thereby avoiding iatrogenic harm. Iatrogenic harm refers to distress or negative outcomes caused inadvertently by healthcare providers or the treatment process itself [3,4]. Reacting to splitting with either collusion or rejection can reinforce the client's maladaptive pattern and cause epistemic injury, where the client's experience of distress is invalidated or misrecognized by the care system [4].

- Option 1 (Correct): Setting consistent boundaries while acknowledging the client's feelings and redirecting to therapeutic goals directly addresses the splitting without reinforcing it. Acknowledging the feeling ("I hear that you feel understood right now") validates the client's emotional experience without agreeing with the distorted content ("the others are terrible"). Redirection focuses the interaction on the client's treatment goals, providing a stable, neutral framework that counters the chaos of splitting. This approach prevents the nurse from being drawn into the all-good role, which would inevitably lead to a future all-bad designation.

- Option 2 (Incorrect): Agreeing with the client's assessment to build rapport is a misguided strategy that constitutes collusion. It reinforces the splitting defense and the client's distorted perception of reality. This action can create a false alliance and is a form of iatrogenic harm, as it validates a maladaptive pattern and can lead to team conflict and inconsistent care [3,4].

- Option 3 (Incorrect): Immediately confronting the client and demanding an apology is a punitive and non-therapeutic response. It fails to recognize splitting as a symptom of the disorder and instead moralizes the client's distress. This approach can cause significant epistemic injury by communicating that the client's internal experience is wrong or bad, thereby damaging the therapeutic relationship and potentially escalating self-harm behaviors [3,4].

- Option 4 (Incorrect): Avoiding the client is a form of neglect and abandonment that directly replicates the unstable, rejecting relationships the client likely fears. This response is a clear example of how coercive or exclusionary practices within care can contribute to ongoing distress and trauma-related symptoms [4]. It punishes the client for their symptoms and abandons the professional responsibility to provide consistent, non-judgmental care.

Synthesizing the Evidence for Practice

The systematic review on palliative care in mental health settings highlights that people with mental illnesses, including BPD, often experience poor access to consistent, compassionate care . A core factor influencing their experience is the quality of the therapeutic relationship. For a client with BPD, a predictable, boundaried, and non-reactive nursing approach is a fundamental component of effective care. The nurse's ability to remain neutral and consistent, neither idealized nor devalued, provides a template for psychological integration. This approach directly counteracts the structural exclusion and moralized judgment that critical discourse analysis identifies as sources of harm within traditional psychiatric frameworks [3]. By choosing to set a boundary and redirect to therapeutic work, the nurse provides a safe relational container that acknowledges distress without being destabilized by it, thereby promoting genuine therapeutic progress.References (research sources)

## 임상 시나리오

Managing Splitting in BPDConsistent Boundaries and Validation
When a client with borderline personality disorder exhibits splitting by idealizing one nurse and devaluing others, the priority is to avoid reinforcing this defense mechanism. Acknowledge the underlying feeling without agreeing with the distorted content.

The most therapeutic response is to set consistent limits while redirecting the focus to therapeutic goals. For example, state, "I hear that you are feeling frustrated, but all our team members are here to help you. Let's focus on your coping plan."

CautionNever agree that other staff are "terrible," as this constitutes collusion with splitting and can cause iatrogenic harm by undermining the treatment team. Avoid punitive confrontation or withdrawing care, which reinforces abandonment fears.

## 핵심 개념

- **Splitting** — A primitive defense mechanism in BPD where individuals cannot integrate positive and negative qualities, viewing people or situations as all-good or all-bad.
- **Therapeutic Boundaries** — Professional limits set by the nurse to maintain a safe, consistent, and goal-oriented relationship, crucial for preventing manipulation and role confusion.
- **Iatrogenic Harm** — Inadvertent distress or negative outcomes caused by a healthcare provider's actions or the treatment process itself, such as reinforcing maladaptive behaviors.
- **Emotional Dysregulation** — An inability to manage or modulate emotional responses, leading to intense, unstable moods and interpersonal conflict, a core feature of BPD.
