護理師教導病人自行注射胰島素，哪些關於儲存與使用的指導是正確的？（選所有適合的）
A nurse is teaching a client about self-administration of insulin. Which instructions are appropriate for safe storage and usage? (Select all that apply.)
- AStore unopened vials in the refrigerator✓ 正解將未開封的胰島素瓶存放在冰箱中
- BAvoid exposing insulin to direct sunlight✓ 正解避免讓胰島素暴露於陽光直射下
- CGently roll the insulin vial between palms to mix if cloudy✓ 正解若胰島素混濁，在兩手掌間輕輕滾動混合
- DDiscard insulin after 28 days if stored at room temperature✓ 正解若存放於室溫，28天後丟棄胰島素
- EShake the vial vigorously before drawing up the medication抽取藥物前劇烈搖晃胰島素瓶
胰島素（Insulin）的儲存與使用安全至關重要，直接影響血糖控制效果與病人安全。未開封的胰島素小瓶（vial）應存放在冰箱冷藏（2-8°C），以維持其穩定性與效力。已開封或正在使用的胰島素，若在室溫（約 20-25°C）下儲存，通常建議在 28 天後棄置，因其效力會逐漸下降。無論何種儲存方式，都應避免將胰島素暴露於陽光直射或極端溫度（過熱或過冷），這會破壞其分子結構，影響藥效。對於外觀混濁的胰島素（如 NPH, 混合型胰島素），應輕輕滾動（roll）小瓶於手掌之間來混合，切忌劇烈搖晃（shake），以免產生氣泡，影響劑量準確性，或破壞其懸浮結構。劇烈搖晃（shake vigorously）會損害胰島素，導致藥效降低或劑量不準確，因此是錯誤的操作。
The storage and use of insulin are critically important to safety and directly affect glycemic control and patient safety. Unopened insulin vials should be stored in the refrigerator (2-8°C) to maintain stability and potency. Once opened or in use, insulin stored at room temperature (approximately 20-25°C) is generally recommended to be discarded after 28 days, as its potency gradually declines. Regardless of the storage method, insulin should be protected from direct sunlight and extreme temperatures (hot or cold), as these can disrupt its molecular structure and reduce efficacy. Cloudy insulin (such as NPH or premixed insulin) should be gently rolled between the palms to mix; it must not be shaken vigorously, as shaking creates bubbles that affect dose accuracy or disrupts the suspension. Vigorous shaking damages insulin, resulting in reduced potency or inaccurate dosing, so it is an incorrect technique.
胰島素的儲存與使用指導，台美兩地在原則上完全一致，都強調冷藏未開封品、避免極端溫度與光照、輕柔混合混濁型胰島素、以及開封後在室溫下的使用期限（通常是 28 天）。在具體操作細節的強調上，美國的糖尿病衛教可能更為普及和標準化，例如透過視覺輔具、數位工具（App）輔助。台灣的衛教則可能更多依賴護理師的口頭指導和衛教手冊。此外，美國對於胰島素筆針（insulin pens）的普及率更高，其使用與儲存方式可能與傳統小瓶略有不同，這也是護理師需要注意的細節。
