護理師監測因子癇前症接受靜脈滴注硫酸鎂（Magnesium sulfate）的病人。哪項發現令護理師懷疑發生鎂中毒？
A nurse is monitoring a client receiving an IV infusion of magnesium sulfate for preeclampsia. Which finding should lead the nurse to suspect magnesium toxicity?
- AUrine output of 40 mL/hr尿量為 40 mL/hr
- BBlood pressure 140/90 mmHg血壓 140/90 mmHg
- CAbsence of deep tendon reflexes✓ 正解深腱反射消失
- DHyperactive bowel sounds腸音亢進

硫酸鎂中毒的典型徵象包含：深腱反射（DTR）消失、呼吸抑制（RR < 12）、尿量減少（< 30 mL/hr）以及意識模糊。DTR 消失通常是中毒的最早期臨床指標之一。解毒劑為葡萄糖酸鈣（Calcium gluconate）。
Classic signs of magnesium sulfate toxicity include loss of deep tendon reflexes (DTRs), respiratory depression (RR < 12), decreased urine output (< 30 mL/hr), and altered mental status. Loss of DTRs is usually one of the earliest clinical indicators of toxicity. The antidote is calcium gluconate.

台美產科護理皆將「DTR、呼吸、尿量」列為硫酸鎂治療的三大監測重點。
