哪幾項評估發現應讓護理師暫停給予預定的毛地黃(Digoxin)?(選所有適合的)
Which assessment findings should lead a nurse to hold a scheduled dose of digoxin? (Select all that apply.)
- AApical heart rate of 54 beats per minute✓ 正解心尖心率為每分鐘 54 次
- BSerum potassium level of 3.2 mEq/L✓ 正解血清鉀濃度為 3.2 mEq/L
- CReports of visual disturbances such as yellow halos✓ 正解主訴視覺障礙,如黃視症
- DSerum digoxin level of 1.2 ng/mL血清毛地黃濃度為 1.2 ng/mL
- EBlood pressure of 130/85 mmHg血壓為 130/85 mmHg

Digoxin 具狹窄治療指數。心搏過慢(<60 bpm)、低血鉀(增加毒性風險)及視力改變(中毒徵兆)皆為暫停給藥並通知醫師的指標。治療濃度範圍通常在 0.5-2.0 ng/mL,故選項 D 正常。
Digoxin has a narrow therapeutic index, so bradycardia (apical HR <60 bpm), hypokalemia, and visual disturbances like yellow halos are signs of toxicity requiring the dose to be held. A serum digoxin level of 1.2 ng/mL is within the normal therapeutic range, and blood pressure is not a primary criterion for withholding this specific medication.
✦ 台美臨床差異
兩地均高度依賴護理師對心搏過慢的判斷;美國護理教育更強調自主評估血鉀的重要性。
