What should be monitored during a magnesium sulfate infusion?

• A. Only blood pressure
• B. Only temperature
• C. Deep tendon reflexes, respiratory rate, and urinary output
• D. Only pulse

Answer: (C)

Monitoring during a magnesium sulfate infusion is crucial for ensuring patient safety and effective treatment. The correct choice emphasizes the need to assess deep tendon reflexes, respiratory rate, and urinary output because these parameters are integral to identifying potential complications of magnesium sulfate therapy.

Deep tendon reflexes help assess the neurological status and detect any signs of magnesium toxicity, as hypermagnesemia can lead to diminished reflexes. Respiratory rate is vital because magnesium sulfate can cause respiratory depression; changes in breathing patterns could indicate that the patient is experiencing adverse effects. Urinary output is monitored to evaluate kidney function and ensure that the body is excreting magnesium appropriately, preventing toxic buildup in the system.

The other options focus on isolated parameters that do not provide a comprehensive assessment. Monitoring only blood pressure, temperature, or pulse does not give a complete picture of the patient’s condition or the effects of magnesium sulfate. Therefore, the combination of deep tendon reflexes, respiratory rate, and urinary output offers a thorough monitoring approach essential for patient safety during treatment.
