一位子癇前症病人正接受硫酸鎂點滴治療。下列哪項評估結果需要護理師立即介入?
A client is receiving an infusion of magnesium sulfate for preeclampsia. Which assessment finding requires immediate nursing intervention?
- AUrinary output of 40 mL/hr尿量 40 mL/hr
- BBlood pressure of 140/90 mmHg血壓 140/90 mmHg
- CRespiratory rate of 16 breaths/min呼吸頻率 16 次/分
- DDeep tendon reflexes absent✓ 正解深層肌腱反射消失
— Explanation · 中文詳解 —
硫酸鎂中毒的首要徵象是深部肌腱反射消失(Patellar reflex),接著會出現呼吸抑制。當反射消失時,表示血中鎂濃度過高,護理師應立即停止點滴灌注並準備解毒劑鈣劑(Calcium gluconate)。其餘選項均在正常治療範圍內或非中毒之急迫表徵。
Absent deep tendon reflexes indicate magnesium toxicity, which precedes respiratory depression and cardiac arrest. The nurse must immediately stop the infusion and administer calcium gluconate as an antidote to prevent life-threatening complications.
✦ 台美臨床差異
台灣產科對硫酸鎂監測非常嚴謹,護理師會備好 Calcium gluconate 於床邊,台美臨床規範在此處一致。
