護理師評估病人對於胰島素自我注射的理解，哪些行動顯示技巧正確？（選所有適合的）
A nurse is evaluating a client's understanding of self-administering insulin. Which actions indicate safe technique? (Select all that apply.)
- ARotating injection sites within the same anatomical area✓ 正解在同一解剖區域內輪替注射部位
- BSwabbing the site with alcohol and injecting immediately while wet以酒精擦拭注射部位並趁濕立即注射
- CPinching the skin when using a short needle✓ 正解使用短針頭時捏起皮膚
- DStoring insulin vials in the freezer to preserve potency將胰島素瓶存放在冷凍庫以保持效力
- ECleaning the injection site with an alcohol prep pad✓ 正解以酒精棉片清潔注射部位
胰島素注射重點：部位需輪替（在同一區內分散以防皮下脂肪增生）、注射前消毒（需等酒精乾以防刺痛）、短針頭需捏起皮膚以確保注入皮下而非肌肉。冷凍胰島素會破壞藥效（應冷藏或室溫存放），注射前未乾則會引起皮膚刺痛。
Key points of insulin injection: sites must be rotated (spread within the same anatomical area to prevent lipohypertrophy); the site should be cleansed before injection and the alcohol allowed to dry to prevent stinging; with a short needle the skin should be pinched up to ensure subcutaneous rather than intramuscular delivery. Freezing destroys insulin's potency (it should be refrigerated or stored at room temperature), and injecting before the alcohol dries causes local stinging.
美國衛教趨勢已逐漸簡化酒精消毒步驟（居家環境中，洗手更為關鍵），台灣仍普遍維持酒精消毒規範。
