- ASerosanguineous drainage on the dressing敷料上有漿液血性引流物
- BReport of moderate pain at the incision site切口處有中度疼痛的主訴
- CSudden increase in heart rate and decreased blood pressure✓ 正解心跳突然加快且血壓下降

術後照護中，評估的核心指標為維持生理穩定（Physiological Stability）。當病人出現心跳加速（Tachycardia）合併血壓下降（Hypotension）時，這是休克（Shock）或內出血（Internal Hemorrhage）的典型臨床表現。這種生命徵象的改變，提示循環系統已無法維持足夠的組織灌流，屬於危急狀況，必須立即通知醫師進行急救處置，否則隨時可能演變成低血容性休克（Hypovolemic Shock）甚至器官衰竭。
The key indicator in postoperative care is maintaining physiological stability. When the patient develops tachycardia together with hypotension, this is a classic clinical presentation of shock or internal hemorrhage. This change in vital signs indicates that the circulatory system can no longer maintain adequate tissue perfusion; it is a critical situation, and the physician must be notified immediately for emergency management, otherwise it may progress to hypovolemic shock or even organ failure.
