一位病人發生急性氣喘發作,下列哪項評估發現需要護理師最即時的介入?

A client is experiencing an acute asthma attack. Which assessment finding requires the most immediate intervention by the nurse?

  • AInspiratory wheezing
    吸氣性喘鳴
  • BUse of accessory muscles
    使用輔助呼吸肌肉
  • CTachypnea
    呼吸急促
  • DAbsent breath sounds✓ 正解
    呼吸音消失
Explanation · 中文詳解

氣喘病人若出現呼吸音消失(Silent chest),代表氣道嚴重阻塞且通氣量極低,屬於預兆呼吸衰竭的危急徵象。A(吸氣性喘鳴)、B(使用輔助肌)與 C(呼吸急促)雖顯示病情不穩,但相較於完全聽不到呼吸音,後者更接近窒息與呼吸停止,必須立即採取急救措施。

Absent breath sounds, or a 'silent chest,' indicate severe airway obstruction and critically low ventilation, signaling impending respiratory failure. This finding requires immediate intervention as it represents a more life-threatening status than wheezing or accessory muscle use.

✦ 台美臨床差異

台美臨床均視 Silent chest 為危急,但在評估時美國護理師更常使用 PEFR (尖峰呼氣流速) 監測,台灣臨床多仰賴聽診。
