服用毛地黃（digoxin）的病人主訴視覺出現黃暈及噁心。護理師的第一個行動是什麼？
A client on digoxin therapy reports yellow-tinted vision and nausea. What is the nurse's first action?
- AEncourage the client to drink water鼓勵個案喝水
- BAdminister an antiemetic給予止吐藥
- CCheck the apical heart rate測量心尖脈搏
- DHold the next dose and notify the physician✓ 正解暫停下一劑並通知醫師
黃視症（yellow-tinted vision）與腸胃道不適（噁心、嘔吐）是 Digoxin 中毒的典型徵象。Digoxin 的治療範圍狹窄，中毒可能引發嚴重心律不整。護理師應立即停藥並通知醫師，這是防止中毒惡化的關鍵行動。給予止吐藥會掩蓋中毒徵兆，應避免。心跳檢查固然重要，但已出現中毒症狀時，停藥才是首要動作。
Yellow-tinted vision and gastrointestinal disturbance (nausea, vomiting) are classic signs of digoxin toxicity. Digoxin has a narrow therapeutic window, and toxicity can precipitate serious dysrhythmias. The nurse should immediately hold the medication and notify the physician, which is the key action to prevent further deterioration of toxicity. Administering an antiemetic would mask the signs of toxicity and should be avoided. Checking the heart rate is important, but once symptoms of toxicity have appeared, holding the medication is the priority action.
