護理師監測病人靜脈輸注氯化鉀 20 mEq，下列哪項措施對確保安全至關重要？
A nurse is monitoring a client receiving intravenous potassium chloride 20 mEq. Which action is essential to ensure client safety?
- AAdminister the infusion via a gravity drip透過重力滴注給予輸注
- BVerify the medication is diluted according to facility policy✓ 正解確認藥物已根據機構政策進行稀釋
- CAssess the client's blood pressure every 15 minutes每 15 分鐘評估案主的血壓
- DFlush the IV line with sterile water before administration給藥前用無菌水沖洗靜脈管路
靜脈輸注鉀離子極具腐蝕性，若濃度過高會造成靜脈炎及組織壞死。確認稀釋濃度符合機構指引是防止醫源性傷害的核心。鉀離子嚴禁推注（IV push），A 項需使用輸液幫浦而非重力滴注；D 項應使用生理食鹽水，而非無菌水；C 項主要是監測心電圖變化，而非血壓。
Intravenous potassium is highly caustic; excessive concentrations can cause phlebitis and tissue necrosis. Verifying that the dilution concentration complies with institutional guidelines is central to preventing iatrogenic injury. Potassium must never be administered by IV push; option A requires an infusion pump rather than gravity drip; option D should use normal saline rather than sterile water; option C primarily involves monitoring ECG changes rather than blood pressure.
台美皆嚴格要求鉀離子必須稀釋並經輸液幫浦給予，且不得以靜脈推注方式給藥。
