靜脈鉀離子具有極高危險性。KCl 絕不可直接推注（IV push），必須經過稀釋且嚴格控制滴速（通常不高於 10 mEq/hr），否則會導致心臟驟停。護理師必須確認劑量與輸注速度符合醫囑與安全標準，並確保血管管路通暢，避免滲漏導致組織壞死。
Intravenous potassium chloride is a high-alert medication that must never be given as an IV push due to the risk of fatal cardiac arrhythmias. The nurse must verify the correct concentration and infusion rate, ensuring it is diluted and administered slowly to prevent cardiac toxicity and tissue damage from extravasation.

美台臨床皆視 KCl 為高危險藥物，皆需雙人查對（Double Check）。
