What should be done in the case of magnesium sulfate toxicity?

In the case of magnesium sulfate toxicity, the primary action is to stop the infusion of magnesium sulfate to prevent further complications. This is critical because excessive magnesium can lead to serious side effects such as respiratory depression, hypotension, and cardiac arrest. Administering calcium gluconate is also crucial because it acts as an antidote to counteract the effects of magnesium toxicity. Calcium works to stabilize the cardiac membrane and can help restore normal neuromuscular function.

When faced with symptoms of magnesium toxicity, rapid intervention is required to ensure patient safety, which makes stopping the infusion and administering calcium gluconate the most appropriate and effective response.
