護理師照顧一位因妊娠毒血症(preeclampsia)接受硫酸鎂輸注的病人。哪項是優先評估項目?

A nurse is caring for a client receiving an infusion of magnesium sulfate for preeclampsia. What is the priority assessment?

  • AUrine output
    尿量
  • BBlood glucose levels
    血糖值
  • CMental status changes
    意識狀態改變
  • DDeep tendon reflexes✓ 正解
    深層肌腱反射
Explanation · 中文詳解

硫酸鎂中毒早期徵兆為深部腱反射消失(Patellar reflex loss)。此藥物由腎臟代謝,雖然監測尿量(Urine output)亦重要,但腱反射的消失通常發生在呼吸抑制之前,是臨床最敏感且直接的安全性評估指標。護理師需監測反射、呼吸次數及尿量。

Deep tendon reflexes are the priority assessment because their loss is the earliest and most sensitive sign of magnesium sulfate toxicity. While urine output is important for monitoring excretion, reflex changes occur before respiratory depression, making them the critical indicator for immediate safety intervention.

✦ 台美臨床差異

台美臨床均採用此監測指標,但美國更傾向將反射評估標準化紀錄於 Flowsheet 中,台灣則視各醫院產科常規而定。
