護理師準備為病人靜脈注射氯化鉀，哪項措施對確保病人安全至關重要？
A nurse is preparing to administer potassium chloride IV to a client. Which action is essential for patient safety?
- AAdminister the medication via IV push to ensure rapid effect經靜脈推注給藥以確保快速療效
- BUse a peripheral line instead of a central line使用周邊靜脈導管而非中心靜脈導管
- CInfuse the potassium at a rate of 40 mEq/hour以每小時 40 mEq 的速率輸注鉀離子
- DVerify the medication is diluted according to facility policy✓ 正解確認藥物已依照機構政策稀釋
— Explanation · 中文詳解 —
氯化鉀絕對禁止直接靜脈推注（IV push），因會導致致命性心律不整。必須嚴格稀釋並依規定速率輸注。中心靜脈給藥通常較安全以防血管刺激；給藥速率通常不超過 10-20 mEq/hr，以免產生心臟毒性。
Potassium chloride must never be administered via IV push due to the high risk of fatal cardiac arrhythmias. It is essential to verify that the medication is properly diluted according to facility policy and administered via controlled infusion. This ensures patient safety by preventing chemical phlebitis and systemic toxicity.
