一位邊緣型人格障礙病人因護理師拒絕其特殊要求而生氣，說道：「大夜班護理師都可以！妳是這裡最爛的護理師。」這是哪種防衛機轉？
A client with borderline personality disorder becomes angry when the nurse refuses to grant a special request. The client says, 'The night nurse let me do it! You are the worst nurse here.' This is an example of which defense mechanism?
- ASplitting✓ 正解分裂
- BRationalization合理化
- CReaction Formation反向作用
- DProjection投射
分裂（Splitting）是邊緣型人格障礙常見的原始防衛機轉，表現為將人或事物看作「全好」或「全壞」，無法整合他人的優缺點。病人藉此操縱工作人員（Staff splitting），造成團隊矛盾。B 是將自身感受歸咎他人；C 是找藉口；D 是表現出與內心相反的行為。
Splitting is a primitive defense mechanism commonly seen in borderline personality disorder, manifesting as viewing people or things as all good or all bad and being unable to integrate the strengths and weaknesses of others. The client may use this to manipulate staff (staff splitting), creating conflict within the team. Option D is attributing one's own feelings to others; option B is making excuses; option C is displaying behavior opposite to one's inner feelings.
臨床處理原則一致。美國精神科護理非常強調團隊間的 Consistency（一致性）以對抗 Splitting。
