護理師準備給予心衰竭病人毛地黃(Digoxin),下列哪些狀況應暫停給藥?(選所有適合的)
A nurse is preparing to administer digoxin to a client with heart failure. Which findings warrant holding the dose? (Select all that apply.)
- AApical pulse rate of 54 beats/min✓ 正解心尖脈搏速率為每分鐘 54 次
- BClient complains of seeing yellow-green halos✓ 正解病人主訴看到黃綠色光暈
- CSerum potassium level of 3.2 mEq/L✓ 正解血清鉀濃度為 3.2 mEq/L
- DBlood pressure of 130/85 mmHg血壓為 130/85 mmHg
- ESerum digoxin level of 1.2 ng/mL血清毛地黃濃度為 1.2 ng/mL

毛地黃毒性反應的關鍵指標包括:心跳過慢(小於 60 次/分)、視覺障礙(如黃綠色光暈)、以及電解質異常。低血鉀(3.2 mEq/L)會顯著增加毛地黃毒性風險。選項 E 在治療範圍內(0.5-2.0 ng/mL),選項 D 為正常血壓,無需停藥。
Digoxin toxicity is indicated by bradycardia (apical pulse <60 bpm), visual disturbances such as yellow-green halos, and hypokalemia, which potentiates digoxin effects. Therefore, the nurse should hold the dose for options A, B, and C.

美台皆嚴格遵循心跳測量標準,且在低血鉀時需特別注意監測此藥。
