護理師即將給予心衰竭病人 digoxin 0.25 mg。投藥前，下列哪項評估最關鍵？
A nurse is administering digoxin 0.25 mg orally to a client with heart failure. Before administration, which assessment is most essential?
- AReviewing the client’s serum potassium level檢視病人的血清鉀濃度
- BAssessing the client’s blood pressure評估病人的血壓
- CChecking the apical pulse for one full minute✓ 正解完整測量心尖脈搏一分鐘
- DEvaluating the client’s respiratory rate評估病人的呼吸頻率
— Explanation · 中文詳解 —
Digoxin 具負性變時作用（減緩心跳），若心跳過慢（成人 < 60 bpm）會導致毒性或嚴重過緩。給藥前必須聽診心尖脈一整分鐘以確認安全。鉀離子數值雖重要，但心跳頻率是臨床給藥的最後一道防線，若心跳過慢則直接暫停給藥。
Checking the apical pulse for one full minute is essential before administering digoxin because the drug slows the heart rate, and administration is contraindicated if the pulse is below 60 beats per minute in adults. Although potassium levels influence toxicity risk, the immediate assessment of heart rate is the primary safety check to prevent severe bradycardia.
✦ 台美臨床差異
美台臨床對於 Digoxin 給藥標準一致，皆嚴格執行心跳 < 60 bpm 暫停給藥。
