一位第一型糖尿病病人被開立速效胰島素（Regular）與中效胰島素（NPH）。護理師應如何準備注射？
A client with type 1 diabetes is prescribed Regular Insulin and NPH insulin. How should the nurse prepare the injection?
- AInject air into the Regular vial first先將空氣注入速效胰島素瓶中
- BDraw NPH first, then Regular insulin先抽取中效胰島素，再抽取速效胰島素
- CDraw Regular insulin first, then NPH✓ 正解先抽取速效胰島素，再抽取中效胰島素
- DShake the Regular insulin vial vigorously用力搖晃速效胰島素瓶
— Explanation · 中文詳解 —
混和胰島素時應遵循「先清（Clear）後濁（Cloudy）」的原則。Regular 是清澈的，NPH 是混濁的。若先抽混濁液體，可能會汙染清澈液體的瓶子，導致作用性質改變，因此應先抽取透明的 Regular。
When mixing insulins, the nurse must draw up the clear Regular insulin before the cloudy NPH insulin to prevent contaminating the clear vial. Contaminating the Regular insulin with NPH could alter its onset and duration of action, compromising glycemic control.
