護理師準備給予心衰竭病人 digoxin 0.25 mg 口服。給藥前，優先評估下列何者最為重要？
A nurse is administering digoxin 0.25 mg orally to a client with heart failure. Before administration, which assessment finding is most important to prioritize?
- ABlood pressure血壓
- BSerum potassium level血清鉀濃度
- CRespiratory rate呼吸頻率
- DApical heart rate✓ 正解心尖脈搏
— Explanation · 中文詳解 —
Digoxin 具負性變時作用（減慢心跳）。給藥前務必測量心尖脈，若成人心跳低於 60 次/分則需暫停給藥，以防嚴重緩脈。雖然血鉀（B）異常會增加中毒風險，但直接測量心跳是確保給藥安全的當下最直接指標。
Because digoxin has negative chronotropic effects, the nurse must prioritize assessing the apical heart rate before administration. The dose should be withheld if the adult heart rate is below 60 beats per minute to prevent toxicity.
✦ 台美臨床差異
台美臨床均要求給藥前測量心跳，但台灣護理紀錄對於心跳未達標的暫停給藥原因需更詳實記錄。
