給予靜脈注射 Diltiazem 時，需要下列哪項護理介入？
Which of the following interventions is required when administering a dose of IV Diltiazem?
- ACheck blood glucose檢查血糖
- BMonitor urine output監測尿量
- CContinuous cardiac monitoring✓ 正解持續心電圖監測
- DAssess breath sounds評估呼吸音
Diltiazem 是一種非二氫吡啶類鈣離子通道阻斷劑（Non-dihydropyridine Calcium Channel Blocker），主要透過抑制房室結（AV node）傳導來減慢心室速率，常用於心房顫動（Atrial Fibrillation）或心房撲動。由於該藥物具有負性變時（Negative chronotropic）與負性變力（Negative inotropic）作用，可能導致嚴重心搏過緩、心臟傳導阻滯或低血壓，因此在靜脈給藥期間，必須進行連續心電圖（Continuous ECG monitoring）與血壓監測，以確保病人血流動力學穩定。
Diltiazem is a non-dihydropyridine calcium channel blocker that slows ventricular rate primarily by inhibiting conduction through the AV node; it is commonly used in atrial fibrillation and atrial flutter. Because the drug exerts both negative chronotropic and negative inotropic effects, it may cause severe bradycardia, heart block, or hypotension. Therefore, continuous ECG and blood pressure monitoring are essential during IV administration to ensure hemodynamic stability.
