護理師準備為病人給予毛地黃（Digoxin），哪項評估結果需要暫停給藥？
A nurse is preparing to administer digoxin to a client. Which assessment finding requires the nurse to withhold the medication?
- AApical pulse of 52 beats per minute✓ 正解心尖脈搏為每分鐘 52 次
- BClient reports mild nausea病人報告輕微噁心
- CBlood pressure of 130/80 mmHg血壓為 130/80 mmHg
- DPotassium level of 4.2 mEq/L鉀離子濃度為 4.2 mEq/L
毛地黃（Digoxin）具有正向肌力與負向變時作用，會降低心跳速率。在給藥前，評估心跳速率（Apical pulse）是絕對必要的安全步驟。若成人心跳低於每分鐘 60 次，給藥可能引發嚴重的心動過緩（Bradycardia）或房室傳導阻滯。此外，毛地黃的中毒徵兆包括厭食、噁心、嘔吐及視覺障礙，護理師給藥前必須綜合評估這些症狀。
Digoxin has a positive inotropic and negative chronotropic effect, slowing the heart rate. Assessing the apical pulse before administration is an absolutely essential safety step. If the adult heart rate is below 60 beats per minute, administering the medication may precipitate severe bradycardia or atrioventricular block. Additionally, digoxin toxicity manifests with anorexia, nausea, vomiting, and visual disturbances, all of which the nurse must comprehensively evaluate before administration.
