- AThe nurse checks the infusion pump settings.護理師檢查輸注幫浦設定
- BThe nurse verifies the client's potassium level on the chart.護理師查對病歷上的病人鉀離子數值
- CThe nurse prepares to administer the potassium via IV push.✓ 正解護理師準備以靜脈推注方式給予鉀離子
- DThe nurse assesses the patency of the peripheral IV site.護理師評估周邊靜脈注射部位的通暢度
— Explanation · 中文詳解 —
氯化鉀絕對禁止採取靜脈推注（IV Push），因為這會導致心律不整及心跳停止。標準操作流程必須將其稀釋後，透過輸液幫浦以受控速度（通常不超過 10 mEq/hr）給藥。新進人員若採取推注行為，必須立即制止並進行臨床教學。
Intravenous push administration of potassium chloride is strictly contraindicated because it can cause fatal cardiac arrhythmias or arrest. Potassium must always be diluted and administered via an infusion pump at a controlled rate to ensure patient safety.
