A nurse is admitting a client who is at 37 weeks of gestation and has severe gestational hypertension. Which of the following actions should the nurse expect to implement? (Select all that apply.)

A. Calcium gluconate is the antidote for magnesium sulfate toxicity and must be immediately available when administering magnesium sulfate for seizure prophylaxis in severe gestational hypertension. B. Respiratory status should be assessed frequently (ideally every 15–30 minutes during magnesium infusion) because magnesium sulfate can cause respiratory depression; assessing only every 4 hours is inadequate. C. A dark, quiet environment helps reduce stimulation, which can minimize seizure risk in clients with severe hypertension or preeclampsia. D. Magnesium sulfate IV is commonly prescribed to prevent eclampsia in clients with severe gestational hypertension. E. Neurologic status should be evaluated frequently (e.g., every 1–2 hours) rather than every 8 hours to monitor for early signs of worsening preeclampsia or magnesium toxicity.
