護理師準備靜脈輸注氯化鉀，下列哪項安全措施最為關鍵？
A nurse is preparing to administer potassium chloride intravenously. Which safety action is critical?
- AOnly use a peripheral IV line僅使用周邊靜脈導管
- BAdminister as a bolus push以推注方式給予
- CVerify the presence of a central line for all infusions確認所有輸注均有中央靜脈導管
- DEnsure the concentration does not exceed 10 mEq/100 mL✓ 正解確保濃度不超過 10 mEq/100 mL
— Explanation · 中文詳解 —
鉀離子注射液具有高危險性，嚴禁直接推注（bolus）。為預防靜脈炎及心律不整，周邊靜脈給藥濃度不可高於 10 mEq/100 mL，且給藥速率通常限制在每小時不超過 10-20 mEq，以確保病人安全。
Potassium chloride injection is high-alert and must never be given by direct IV bolus. To prevent phlebitis and arrhythmias, the concentration for peripheral administration should not exceed 10 mEq per 100 mL, and the infusion rate is generally limited to no more than 10-20 mEq per hour to ensure patient safety.
✦ 台美臨床差異
美國護理師常依據儀器設定自動偵測輸注速率，台灣則多仰賴護理師雙重核對藥物濃度與輸注泵浦設定。
