Review Antenatal care for complicated pregnancies related questions and content

A labor and birth nurse receives a call from the laboratory regarding a preeclamptic patient receiving an IV infusion of magnesium sulfate. The laboratory technician reports that the patient's magnesium level is 7.6 mg/dL. What is the nurse's priority action?

  • A. Stop the infusion of magnesium.
  • B. Assess the patient's respiratory rate.
  • C. Assess the patient's deep tendon reflexes.
  • D. Notify the health care provider of the magnesium level.
Correct Answer: B

Rationale: The correct answer is B: Assess the patient's respiratory rate. A magnesium level of 7.6 mg/dL is above the therapeutic range (4-7 mg/dL) and can lead to magnesium toxicity. Respiratory depression is a common early sign of magnesium toxicity. Assessing the patient's respiratory rate is the priority to monitor for this potentially life-threatening complication. Stopping the infusion of magnesium (Choice A) is not the immediate priority as the patient's respiratory status needs to be assessed first. Assessing deep tendon reflexes (Choice C) is important for magnesium toxicity but not as urgent as assessing respiratory rate. Notifying the health care provider (Choice D) can be done after assessing the patient's respiratory rate.
