True or False: Drowsiness is expected with magnesium sulfate infusion.

• A. True
• B. False
• C. Only in started doses
• D. Only in advanced stages of pregnancy

Answer: (A)

Drowsiness is indeed an expected side effect of magnesium sulfate infusion. Magnesium sulfate is commonly used in obstetric settings primarily for its neuroprotective effects in preterm labor and for the prevention and treatment of eclampsia. One of the pharmacological effects of magnesium is sedation, which can lead to drowsiness in patients receiving the infusion.

This sedation occurs due to the central nervous system depressant effects of magnesium. Therefore, when administering magnesium sulfate, healthcare providers often monitor patients for signs of drowsiness and lethargy as part of their assessment of the medication's effects. In contrast, the other statements suggest conditions that do not directly relate to the expected side effects of the drug, making them less relevant to the primary concern of drowsiness during magnesium sulfate infusion.
