護理師給予病人 Digoxin。哪項評估為必要？
A nurse is administering a dose of digoxin. Which assessment is mandatory?
- AApical heart rate✓ 正解心尖脈搏
- BBlood pressure血壓
- CRespiratory rate呼吸頻率
- DPeripheral pulse周邊脈搏
— Explanation · 中文詳解 —
Digoxin 具有負性變時作用（Negative chronotropic effect）。給藥前必須聽診心尖脈（Apical rate）完整一分鐘。若成人的心跳小於 60 次/分，則須停藥並通知醫師，以防藥物中毒。 peripheral pulse 測量不夠準確。
Because digoxin has a negative chronotropic effect, the nurse must assess the apical heart rate for a full minute prior to administration. The dose should be withheld and the provider notified if the adult heart rate falls below 60 beats per minute to prevent toxicity.
✦ 台美臨床差異
兩地均將心尖脈 <60 bpm 作為 Digoxin 給藥的安全標準。
