護理師準備靜脈輸注氯化鉀（KCl）。為預防組織傷害，下列哪項護理介入是必須的？
A nurse is preparing to administer potassium chloride IV. Which intervention is essential to prevent tissue injury?
- AAdminister via a rapid push method採用快速推注方式給藥
- BUse an IV site on the lower extremity使用下肢的靜脈注射部位
- CDilute the medication properly per facility protocol✓ 正解依照機構規定適當稀釋藥物
- DApply a cold compress to the site在注射部位應用冷敷
氯化鉀（KCl）具有強烈的組織刺激性，一旦外滲（extravasation）極易造成嚴重的血管壞死甚至組織壞疽。為了預防組織傷害，給藥前必須依照藥典規定進行稀釋（通常稀釋至適當濃度），且嚴禁靜脈直接推注（IV Push）。透過輸液幫浦定量給藥，可確保流速穩定，避免局部濃度過高導致血管傷害。這是給予靜脈鉀離子的基本護理安全規範。
Potassium chloride (KCl) is highly irritating to tissues; extravasation can cause severe vascular necrosis or even tissue gangrene. To prevent tissue injury, the medication must be diluted in accordance with established standards (typically to an appropriate concentration), and IV push administration is strictly prohibited. Using an infusion pump for controlled delivery ensures a stable rate and prevents localized high concentrations that could cause vascular damage. These are fundamental nursing safety standards for intravenous potassium administration.
