護理師準備給予皮下注射依諾肝素（Enoxaparin）。哪項操作是正確的？
A nurse is administering a dose of subcutaneous enoxaparin. Which action is appropriate?
- AExpel the air bubble from the prefilled syringe將預充式針筒中的空氣泡排出
- BMassage the injection site after administration注射後按摩注射部位
- CAspirate before injecting the medication注射前進行抽吸
- DAdminister the injection in the abdominal wall✓ 正解在腹壁進行注射
— Explanation · 中文詳解 —
依諾肝素為低分子量肝素，注射部位通常選擇腹部兩側脂肪層。該藥物預充式針筒內的氣泡設計目的是為了確保劑量完全注入。絕對不可揉搓（massage）注射部位，以免造成皮下瘀血，也不需要抽回血（aspirate），因為對皮下注射而言並非必要步驟。
The abdomen is the preferred site for subcutaneous enoxaparin administration due to consistent absorption in the fatty tissue. The air bubble in the prefilled syringe should not be expelled, as it helps ensure the full dose is delivered into the subcutaneous layer. Massaging the site is contraindicated to prevent bruising, and aspiration is unnecessary for subcutaneous injections.

台美皆強調不揉搓，但臨床上部分醫護人員仍有舊習慣，需持續教育訓練。
