一位患有重症肌無力的病人，下列哪些症狀提示可能發生肌無力危機？（選所有適合的）
A nurse is caring for a client with a history of Myasthenia Gravis. Which symptoms suggest a myasthenic crisis? (Select all that apply.)
- ATachycardia✓ 正解心搏過速
- BInability to swallow✓ 正解無法吞嚥
- CRespiratory distress✓ 正解呼吸窘迫
- DImproved muscle strength with Edrophonium注射 Edrophonium 後肌力改善
- EExcessive salivation唾液分泌過多
肌無力危機（myasthenic crisis）的「症狀」包括：A. 心搏過速（呼吸肌無力導致換氣不足的代償反應）；B. 吞嚥困難（球部肌無力）；C. 呼吸窘迫（呼吸肌麻痺，需插管）。錯誤：D. Edrophonium (Tensilon) 測試後肌力改善是診斷測試結果，可用以鑑別肌無力危機與膽鹼激性危機，但本身不是「症狀」；E. 過度流涎為膽鹼激性危機（cholinergic crisis）的徵象，非肌無力危機。
The symptoms of myasthenic crisis include: A. tachycardia (a compensatory response to hypoventilation from respiratory muscle weakness); B. inability to swallow (bulbar muscle weakness); C. respiratory distress (paralysis of respiratory muscles requiring intubation). Incorrect: D. improved muscle strength after edrophonium (Tensilon) is a diagnostic test result that helps differentiate myasthenic from cholinergic crisis, but it is not itself a symptom; E. excessive salivation is a sign of cholinergic crisis, not myasthenic crisis.
美國護理界對 Tensilon 測試的使用趨於保守，台灣臨床仍依據醫院標準流程執行。
