  • 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

Explanation · 中文詳解

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.

✦ 台美臨床差異

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。
