護理師準備對心衰竭病人給予地高辛（Digoxin），給藥前最需優先進行哪項評估？
A nurse is administering a dose of digoxin to a patient with heart failure. Which clinical assessment is priority before the nurse administers the medication?
- AAuscultate the apical pulse for one full minute✓ 正解聽診心尖脈搏整整一分鐘
- BAssess the client's peripheral edema評估病人的周邊水腫
- CCheck the client's blood pressure檢查病人的血壓
- DObserve the client's respiratory rate觀察病人的呼吸頻率
地高辛（Digoxin）具有正性肌力作用，但同時具備負性變時作用（減慢心跳）。給藥前的優先評估是測量心尖脈（Apical pulse）滿 1 分鐘，若成人心跳低於每分鐘 60 次，則必須暫停給藥並通知醫師，以避免引發心搏過緩（Bradycardia）或嚴重的藥物中毒。此評估比血壓或水腫更具立即性的臨床安全意義。
Digoxin has a positive inotropic effect but also a negative chronotropic effect (slowing the heart rate). The priority assessment before administration is to measure the apical pulse for one full minute. If the adult heart rate is below 60 beats per minute, the dose must be withheld and the physician notified to avoid causing bradycardia or severe digoxin toxicity. This assessment has more immediate clinical safety significance than blood pressure or edema.
