護理師教導病人自行皮下注射胰島素，哪項動作顯示技術正確？
A nurse is teaching a client about self-administration of subcutaneous insulin. Which action by the client shows correct technique?
- AInject at a 90-degree angle✓ 正解以 90 度角注射
- BInject into the same spot every time每次都注射在同一部位
- CAspirate before injecting注射前進行抽吸
- DMassage the site vigorously after injection注射後用力按摩注射部位
— Explanation · 中文詳解 —
皮下注射胰島素應使用短針頭，以 90 度垂直注射，確保藥物進入皮下組織而非肌肉層。不需抽吸（回血），因皮下組織血管稀少。必須輪替注射部位（Rotation）以預防皮下脂肪增生。按摩會加速胰島素吸收，改變預期藥效，故不建議。
Insulin should be injected at a 90-degree angle to ensure delivery into the subcutaneous tissue rather than the muscle. Site rotation is essential to prevent lipohypertrophy, and aspiration is unnecessary because subcutaneous tissue has few blood vessels.
✦ 台美臨床差異
美台臨床衛教原則已同步，強調 90 度注射與部位輪替，已不再教學抽吸步驟。
