一位45歲女性前來急診室時跛行著。她在經歷了一場令人精疲力竭且擁擠的 14 小時國際航班後,抱怨有嚴重的右小腿痛。護理師主動觀察個案的右腿。哪一組教科書級的臨床評估發現具體指示了極度深嵌的深部靜脈栓塞(DVT)的高風險潛力?而在現代,哪一項過時的手動評估手法現在被嚴格視為絕對禁忌?
A 45-year-old female presents to the emergency department limping, complaining of severe right calf pain after completing a grueling 14-hour cramped international flight. The nurse actively observes the client's right leg. Which set of textbook clinical assessment findings specifically indicates a high-risk potential for a deeply lodged Deep Vein Thrombosis (DVT), and which outdated manual assessment maneuver is now strictly contraindicated?
- ATingling, burning needle-like neuropathic pain shooting down both feet equally; contraindicated: Directly applying a tightly sealed warm compress.雙腳均勻出現刺痛、灼熱感及針刺樣神經病變疼痛;禁忌:直接敷貼緊密封閉的熱敷包
- BBilateral leg paleness with profound foot coldness; contraindicated: Performing vigorous deep deep-tissue massage on both calves.雙腿蒼白且足部極度冰冷;禁忌:對雙側小腿進行劇烈的深層組織按摩
- CUnilateral calf swelling (edema), localized warmth, and prominent erythema; contraindicated: Forcibly performing Homan's sign (dorsiflexing the foot).✓ 正解單側小腿腫脹(水腫)、局部發熱及明顯紅斑;禁忌:強制執行霍曼氏徵象(足背屈)
- DPulsating calf bruises combined with a complete loss of the pedal pulse; contraindicated: Elevating the affected leg relentlessly above the heart.搏動性小腿瘀斑伴隨足背脈搏完全消失;禁忌:持續將患肢抬高超過心臟水平
本題測驗高風險心血管併發症:深層靜脈栓塞 (DVT) 的臨床確認與過時評估的物理禁忌。深層靜脈栓塞主要發生在單一側的小腿深層靜脈(長期久坐不活動是最大殺手)。因為靜脈被血塊堵死,富含水分與廢物的靜脈血無法流回心臟,只能全部淹積在患肢。這會導致教科書級的『單側』腫脹水腫(Unilateral swelling)、局部因發炎產生的熱感(Warmth)與發紅(Erythema/Redness)。降低風險的關鍵在於『預防肺栓塞』:絕不能讓已經生成的血塊脫落。因此,所有護理師皆被嚴格禁止對腫脹小腿執行舊式的「霍曼氏徵象(Homan's sign)」:即用力將病患的腳板向上彎折(Dorsiflexion)來測試小腿痛覺。因為這種物理擠壓肌肉的暴力動作,會直接將血塊擠壓脫落(Dislodge the clot),讓血塊變成一顆致命的導彈發射進入肺臟引發肺大栓塞 (Pulmonary Embolism)(選項C為正解)。選項B的雙側蒼白冰冷為動脈阻塞,而非靜脈栓塞。選項A的針刺感為糖尿病神經病變或坐骨神經痛。
This question tests recognition of DVT and the contraindicated assessment maneuver. DVT typically occurs in one lower extremity (immobility is a major risk factor). Because the deep vein is obstructed, blood pools in the affected limb, producing unilateral swelling (edema), localized warmth, and erythema. The key goal is to prevent pulmonary embolism by not dislodging the clot. Homan's sign (forcibly dorsiflexing the foot to elicit calf pain) is contraindicated because the physical compression of the calf can dislodge the clot and cause a fatal pulmonary embolism. Option B's bilateral pale/cold limbs describes arterial occlusion; option A describes neuropathic pain (e.g., diabetic neuropathy).
「廢除 Homan's Sign」是過去十幾年來全球醫護界共通的最強烈心臟血管指引。只要看到選項有「折腿 (Dorsiflexion)」或「幫單側腫脹處按摩揉一揉(Massage)」,這絕對是害死病人的陷阱,直接劃掉。
