- CMassage the site vigorously after injection注射後用力按摩注射部位

— Explanation · 中文詳解 —
依諾肝素為低分子量肝素，注射部位應選擇腹部皮下組織，並與肚臍保持至少 5 公分距離，以防瘀血。B 錯誤：注射低分子肝素無需抽吸。C 錯誤：按摩會增加瘀血風險。A 錯誤：預充式針筒內的氣泡設計旨在確保藥物完全排出，不可預先排出。
Enoxaparin should be injected into the abdominal subcutaneous tissue, maintaining a safe distance from the umbilicus to minimize bruising. The air bubble in prefilled syringes should not be expelled, as it helps lock the medication in the tissue. Aspiration is contraindicated for low-molecular-weight heparins, and vigorous massage of the site should be avoided to prevent hematoma formation.
