Correct Answer is D
Explanation
Choice A Reason: This is incorrect because ferrous sulfate is an iron supplement that is used to treat or prevent iron-deficiency anemia. It has no effect on magnesium sulfate, which is a medication that lowers blood pressure and prevents seizures in severe preeclampsia.
Choice B Reason: This is incorrect because potassium chloride is an electrolyte supplement that is used to treat or prevent low levels of potassium in the blood. It has no effect on magnesium sulfate, which can cause hypermagnesemia, or high levels of magnesium in the blood.
Choice C Reason: This is incorrect because calcium carbonate is an antacid that is used to treat or prevent heartburn, indigestion, or calcium deficiency. It has no effect on magnesium sulfate, which can cause hypocalcemia, or low levels of calcium in the blood.
Choice D Reason: This is correct because calcium gluconate is an antidote that is used to treat magnesium toxicity, which can occur when magnesium sulfate is given in high doses or for prolonged periods. Calcium gluconate reverses the effects of magnesium sulfate on the neuromuscular and cardiovascular systems, such as muscle weakness, respiratory depression, cardiac arrhythmias, or cardiac arrest.
