Explanation

(A) MgSO4is a central nervous system depressant. Loss of reflexes is often the first sign of developing toxicity. (B) Urinary output at <25 mL/hr or 100 mL in 4 hours may result in the accumulation of toxic levels of magnesium. (C) The therapeutic serum range for MgSO4is 6-8 mg/dL. Higher levels indicate toxicity. (D) Respirations of>16 breaths/min indicate that toxic levels of magnesium have not been reached. Medication administration would be safe.
