第一型糖尿病病人需同時施打 NPH 胰島素與規則（Regular）胰島素。護理師在將兩者混合於同一針筒時，第一步應執行什麼動作？
A client with type 1 diabetes mellitus is prescribed NPH insulin and regular insulin. When mixing these medications in one syringe, which step should the nurse perform first?
- AWithdraw the Regular insulin first先抽取規則胰島素
- BInject air into the NPH insulin vial✓ 正解向 NPH 胰島素瓶中注入空氣
- CInject air into the Regular insulin vial向規則胰島素瓶中注入空氣
- DRoll the NPH insulin vial between palms在掌心間滾動 NPH 胰島素瓶

混合胰島素的標準步驟為：先將空氣注入 NPH（混濁）瓶內（不吸出），再將空氣注入 Regular（澄清）瓶內，接著吸取 Regular，最後吸取 NPH。此順序旨在避免將混濁的 NPH 帶入澄清的 Regular 瓶中，以維持藥品純度。
When mixing NPH and regular insulin in one syringe, the nurse must first inject air into the NPH vial without withdrawing any medication. This specific sequence prevents contaminating the clear regular insulin vial with the cloudy NPH suspension, thereby maintaining medication purity.
✦ 台美臨床差異
全球糖尿病護理標準一致，但在台灣臨床實務中，病人常因衛教差異改為使用預混型胰島素，減少混合錯誤。
