病人診斷為深層靜脈栓塞（DVT）。哪項評估發現需要立即通知醫師？
A client is diagnosed with deep vein thrombosis (DVT). Which assessment finding requires immediate notification to the primary healthcare provider?
- APain upon dorsiflexion of the foot足背屈時疼痛
- BIncreased warmth and redness in the affected leg患肢溫度和紅腫增加
- CSudden onset of dyspnea and tachycardia✓ 正解突然出現呼吸困難和心跳過速
- DMild edema of the ankle on the affected side患側腳踝輕微水腫
DVT 病人最致命的併發症是肺栓塞（PE）。突發性的呼吸困難（Dyspnea）及心跳過速（Tachycardia）是 PE 的經典徵兆，代表栓子已脫落並進入肺循環，這是危及生命的緊急情況。其餘選項皆為 DVT 的常見臨床表現，需持續監測但不如呼吸道症狀急迫。
Sudden onset of dyspnea and tachycardia in a client with deep vein thrombosis (DVT) suggests a pulmonary embolism, a life-threatening emergency where a clot has migrated to the lungs. While pain on dorsiflexion, warmth, redness, and edema are expected local signs of DVT, respiratory distress indicates systemic complications. Immediate notification of the provider is essential for urgent evaluation and treatment.
在美國，這類評估異常通常透過 SBAR 立即通報 Rapid Response Team，台灣則視院內規定通知值班醫師處理。
