護理師指導病人自我注射胰島素。下列哪些敘述表示病人已了解？（選所有適合的）
A nurse is teaching a client about self-administration of insulin. Which of the following statements by the client indicates understanding? (Select all that apply.)
- AI should rotate injection sites to prevent lipodystrophy✓ 正解我應該輪替注射部位以防止脂肪營養不良
- BI can store my unopened insulin vials in the freezer我可以將未開啟的胰島素瓶存放在冷凍庫
- CI should wash my hands thoroughly before preparing the dose✓ 正解我在準備劑量前應徹底洗手
- DI must discard the needle after every single use✓ 正解我必須在每次使用後丟棄針頭
- EI should inject the insulin into the same spot every day to ensure consistent absorption我應該每天在同一個位置注射胰島素以確保吸收一致
胰島素自我注射衛教重點在於確保安全性與藥效。輪替部位可預防皮下脂肪增生（Lipodystrophy），確保藥物吸收穩定。執行前徹底洗手是預防感染的基本原則。每次使用後丟棄針頭可防止針頭鈍化導致的疼痛，並確保無菌。冷凍會破壞胰島素蛋白質結構，導致藥效失效；而固定部位注射會導致局部組織硬化，嚴重影響吸收效率。
The focus of self-injection insulin teaching is on safety and drug effectiveness. Rotating sites prevents lipodystrophy and ensures stable absorption. Thorough hand washing before preparation is a basic infection-prevention principle. Discarding the needle after each use prevents pain caused by a dulled needle and maintains sterility. Freezing destroys the protein structure of insulin and renders it ineffective, while injecting at the same site causes local tissue hardening and severely impairs absorption efficiency.
