接受硫酸鎂治療子癇前症的孕婦，出現下列哪項評估結果需立即處置？
Which assessment finding in a client receiving intravenous magnesium sulfate for pre-eclampsia requires immediate intervention?
- ARespiratory rate of 10 breaths/min✓ 正解呼吸頻率為每分鐘 10 次
- BSerum magnesium level of 7.0 mg/dL血清鎂濃度為 7.0 mg/dL
- CAbsent deep tendon reflexes深部肌腱反射消失
- DBlood pressure of 140/90 mmHg血壓為 140/90 mmHg
— Explanation · 中文詳解 —
硫酸鎂中毒跡象包括呼吸抑制、肌腱反射消失、尿量減少。呼吸抑制（<12次/分）直接威脅生命安全，需立即停藥並準備葡萄糖酸鈣拮抗。反射消失（C）雖為毒性指標，但呼吸抑制代表已經危及氣道與呼吸，故為優先處置。
A respiratory rate of 10 breaths/min indicates magnesium sulfate toxicity and requires immediate intervention, as respiratory depression is the most life-threatening complication. While absent reflexes also signal toxicity, respiratory status takes priority because it directly compromises airway and breathing safety.
✦ 台美臨床差異
台灣產科病房對於硫酸鎂的監測有非常嚴格的產科護理常規（如每小時監測），執行力道與美國一致。
