- BInject into the abdomen, avoiding the 2-inch area around the umbilicus✓ 正解注射於腹部，避開肚臍周圍兩英吋範圍
- CExpel the air bubble in the prefilled syringe before injection注射前排出預充式針筒內的氣泡
- DAspirate before injecting the medication注射前進行回抽
— Explanation · 中文詳解 —
Enoxaparin 為低分子量肝素（LMWH），應注射於腹部脂肪，並與肚臍保持約 5 公分（2 英寸）距離。D 選項錯誤，注射肝素類藥物不可回抽，以免導致組織出血或瘀血。A 選項錯誤，按摩會導致局部出血風險增加。C 選項錯誤，針筒內的小氣泡可封住藥物，不應排除。
Enoxaparin should be administered via deep subcutaneous injection into the abdominal fat, maintaining a distance of approximately 2 inches from the umbilicus to ensure consistent absorption. Aspiration and massaging the site are contraindicated as they increase the risk of tissue trauma and hematoma formation.
✦ 台美臨床差異
台美臨床對 LMWH 注射規範趨於一致，重點皆在於「不回抽、不按摩」。
