護理師正在為病人進行皮下注射依諾肝素（Enoxaparin）。下列哪項操作是正確的？
A nurse is administering a dose of subcutaneous enoxaparin to a client. Which action by the nurse is correct?
- AAdminister the injection in the abdominal fat pad✓ 正解在腹部脂肪墊進行注射
- BAspirate the syringe before pushing the medication推注藥物前回抽注射器
- CExpel the air bubble from the pre-filled syringe before injection注射前從預充式注射器排出氣泡
- DMassage the injection site after administering the medication給藥後按摩注射部位
依諾肝素（Enoxaparin）是一種低分子肝素（LMWH），常以預充式針筒呈現。給藥時，護理師應選在腹部兩側脂肪層注射，以確保藥物吸收。針筒內設計的氣泡（Air bubble）不應在注射前排出，因為它能確保藥液完全進入皮下並密封針道，防止藥液外漏。注射後禁止按摩，以免導致皮下微血管破裂引起瘀斑與出血。此藥物不需回抽，以免造成組織受損。
Enoxaparin is a low-molecular-weight heparin (LMWH) commonly supplied in pre-filled syringes. During administration, the nurse should select a site in the abdominal fat pad (lateral abdomen) to ensure consistent absorption. The air bubble built into the pre-filled syringe should not be expelled before injection, as it ensures that the entire dose enters the subcutaneous tissue and seals the needle track, preventing leakage. Massaging the site after injection is contraindicated, as it may rupture subcutaneous capillaries and cause bruising or bleeding. Aspiration is not required for this medication, as it may injure tissue.
