Which of the following is a side effect of magnesium sulfate?

Magnesium sulfate, commonly used in obstetrics for conditions like preeclampsia and to prevent seizures, has several potential side effects, one of which is respiratory depression. This occurs because magnesium can depress the central nervous system and affect neuromuscular transmission, leading to reduced respiratory drive. Elevated serum magnesium levels, especially above therapeutic range, can exacerbate this effect, resulting in shallow breathing or respiratory arrest in severe cases.

Monitoring of respiratory rate and depth is crucial during magnesium sulfate infusion to prevent this serious side effect. Other side effects, while possible, do not have the same direct impact on respiratory function as respiratory depression. Understanding the implications of magnesium's effects on neuromuscular and respiratory function is vital for safe management during treatment.
