Correct Answer is B
Explanation
Choice A Reason: This is incorrect because difficulty in arousing is a sign of magnesium toxicity, which is a serious complication of magnesium sulfate therapy. Magnesium toxicity can cause central nervous system depression, muscle weakness, and cardiac arrest. The nurse should monitor the client's level of consciousness and stop the infusion if the client becomes lethargic or unresponsive.
Choice B Reason: This is correct because deep tendon reflexes 2+ indicate a normal and expected response to magnesium sulfate therapy. Magnesium sulfate is a muscle relaxant that can reduce the risk of seizures in gestational hypertension. The nurse should assess the client's deep tendon reflexes regularly and maintain them at 2+ or slightly diminished.
Choice C Reason: This is incorrect because urinary output of 30 mL per hour is below the normal range of 40 to 80 mL per hour and may indicate renal impairment or dehydration. Magnesium sulfate can cause renal toxicity or fluid retention, which can affect the urinary output. The nurse should monitor the client's urinary output and fluid balance and report any abnormalities to the doctor.
Choice D Reason: This is incorrect because respiratory rate of 10 breaths/minute is below the normal range of 12 to 20 breaths/minute and may indicate respiratory depression. Magnesium sulfate can cause respiratory depression or failure, which can be life-threatening. The nurse should monitor the client's respiratory rate and oxygen saturation and administer oxygen or antidote if needed.
