術後病人出現何種評估結果，護理師應懷疑其有靜脈栓塞的徵兆？
Which assessment finding in a postoperative client should the nurse interpret as a sign of potential venous thromboembolism?
- AUnilateral calf swelling and tenderness✓ 正解單側小腿腫脹與壓痛
- BAbsence of pedal pulses足背脈搏消失
- CCoolness of the lower extremities下肢發涼
- DBilateral pedal edema雙側足部水腫
術後靜脈栓塞（DVT）的評估是術後照護重點。典型的 DVT 徵兆為「單側」下肢出現腫脹、疼痛、發紅或發熱（即 Homan's sign 的相關臨床表現）。雙側水腫通常與全身性疾病（如心衰竭、腎衰竭）有關，而非 DVT。若出現脈搏消失，則更偏向動脈阻塞。護理師需敏銳觀察這些特徵，以防範肺栓塞（PE）的致命風險。
Assessment for postoperative venous thromboembolism (DVT) is a key part of postoperative care. The classic signs of DVT include 'unilateral' swelling, pain, redness, or warmth of the lower extremity (and related findings such as Homan's sign). Bilateral edema is usually related to systemic conditions (such as heart or renal failure) rather than DVT. Absence of pulse points to arterial occlusion. The nurse must be alert to these features to prevent the life-threatening risk of pulmonary embolism (PE).
