護理師正在為病人進行皮下依諾肝素（Enoxaparin）注射，下列哪項護理措施是正確的？
A nurse is administering a dose of subcutaneous enoxaparin to a client. Which nursing action is correct during the administration?
- AMassage the injection site vigorously after administration注射後用力按摩注射部位
- BAdminister the medication into the anterolateral abdominal wall✓ 正解將藥物注射於腹部前外側壁
- CExpel the air bubble from the prefilled syringe before injection注射前排出預充式注射器中的氣泡
- DAspirate for blood return before injecting the medication注射前抽吸確認有血液回流
依諾肝素（Enoxaparin）為低分子量肝素（LMWH），需注射於皮下脂肪層。注射部位應選擇腹部外側（Anterolateral abdominal wall），避開肚臍周圍（約 5 公分內）。預充填針筒內的氣泡是為了確保藥物全部注入，不可排除。注射後不應按摩，以避免導致皮下組織微血管破裂產生血腫（Hematoma）。皮下注射無需抽吸（Aspiration），因該處血管分佈稀疏，且抽吸可能導致組織損傷。
Administer enoxaparin into the anterolateral abdominal wall, avoiding the area within 5 cm of the umbilicus, to ensure consistent absorption. Do not massage the injection site after administration, as this increases the risk of hematoma formation. The air bubble in the prefilled syringe should not be expelled, as it is intentional to ensure the full dose is delivered. Aspiration is not required for subcutaneous injections because the tissue has sparse blood vessels.
