病人服用毛地黃(Digoxin),哪項評估為強制性?
Which assessment is mandatory for a client receiving digoxin?
- AApical heart rate✓ 正解心尖脈搏
- BBlood glucose level血糖值
- COxygen saturation血氧飽和度
- DSerum potassium level血清鉀離子濃度
毛地黃(Digoxin)是一種強心劑,具有正性肌力作用(增加心肌收縮力)及負性頻率作用(降低心率)。由於它具有窄治療範圍(Narrow therapeutic index),極易產生毒性。在給藥前,護理師必須強制測量心尖脈(Apical pulse)滿一分鐘。若心跳小於 60 次/分(成人),即代表藥物可能導致過度心跳過慢,此時應暫停給藥並通知醫師,以防發生嚴重的房室傳導阻滯或心律不整。
Digoxin is a cardiotonic agent with a positive inotropic effect (increasing myocardial contractility) and a negative chronotropic effect (slowing the heart rate). Because it has a narrow therapeutic index, toxicity occurs easily. Before administration, the nurse must mandatorily auscultate the apical pulse for a full minute. If the rate is less than 60 beats/min (in adults), the medication may cause excessive bradycardia, in which case administration should be withheld and the provider notified to prevent severe AV block or arrhythmias.
