護理師正準備為心臟衰竭病人投予地高辛(Digoxin),若出現何種評估結果應暫停給藥?
A nurse is administering digoxin to a patient with heart failure. Which assessment finding should lead the nurse to withhold the medication?
- AClient reports mild nausea客戶報告輕微噁心
- BApical heart rate of 52 beats/min✓ 正解心尖心率為 52 次/分
- CBlood pressure of 110/70 mmHg血壓為 110/70 mmHg
- DPotassium level of 4.2 mEq/L鉀離子濃度為 4.2 mEq/L

地高辛具有正性肌力與負性頻率作用,成人給藥前若心跳小於 60 次/分,必須暫停給藥並回報醫師,以防發生嚴重心搏過緩或藥物毒性。其他選項如血壓與鉀離子在正常範圍內,噁心感雖為中毒症狀,但若無嚴重異常,心率仍為首要指標。
Digoxin has a negative chronotropic effect, slowing the heart rate; therefore, the nurse must withhold the medication and notify the provider if the apical pulse is below 60 beats/min in adults to prevent severe bradycardia or toxicity.
✦ 台美臨床差異
台美臨床皆嚴格執行給藥前心跳評估,唯台灣護理系統多有電子化警示提醒。
