哪些評估發現屬於庫欣氏三聯徵（Cushing's Triad），代表腦內壓增高？（選所有適合的）
Which assessment findings are part of Cushing's Triad, indicating increased intracranial pressure? (Select all that apply.)
- ABradycardia✓ 正解心跳過緩
- BTachycardia心跳過速
- CWidening pulse pressure✓ 正解脈壓差變寬
- DIrregular respirations✓ 正解呼吸節律不規則
- EHypotension低血壓
庫欣氏三聯徵（Cushing's Triad）是腦壓增高（ICP）導致腦幹受壓的晚期且危急的徵兆。這與一般休克的臨床表現正好相反。核心機轉：1. 寬脈壓（Widening pulse pressure）：收縮壓上升以克服腦壓，但舒張壓維持或下降。2. 心跳過緩（Bradycardia）：因壓力刺激感壓受器導致迷走神經興奮。3. 呼吸不規則（Irregular respirations）：腦幹受壓干擾了呼吸中樞。記住：休克是「心跳快、血壓低」；庫欣氏三聯徵是「心跳慢、收縮壓高」。護理師若在頭部外傷或腦出血病患身上發現這些體徵，必須意識到腦疝脫（Herniation）可能即將發生，是極度緊急的醫療預警。
Cushing's Triad is a late and critical sign of increased intracranial pressure (ICP) causing brainstem compression. Its presentation is opposite to that of typical shock. Core mechanisms: 1. Widening pulse pressure: systolic blood pressure rises to overcome elevated ICP while diastolic pressure remains stable or falls. 2. Bradycardia: pressure stimulates the baroreceptors, increasing vagal tone. 3. Irregular respirations: brainstem compression disrupts the respiratory center. Remember: shock presents as 'fast heart rate, low blood pressure,' while Cushing's Triad presents as 'slow heart rate, high systolic pressure.' If the nurse notes these findings in a client with head trauma or intracranial hemorrhage, it must be recognized that herniation may be imminent, and this is an extremely urgent medical warning.
美國 NCLEX 將庫欣氏三聯徵視為神經外科護理的必考重點，強調與休克徵象的區分；台灣護理師在臨床觀察上同樣重視此三指標，但在術語使用上可能更常直接描述為「ICP Rising」而非頻繁使用「Triad」一詞。
