Potassium iodide.
Lactulose.
Sodium polystyrene sulfonate.
Acetylcysteine.
The Correct Answer is C
Choice A rationale
Potassium iodide is used to treat hyperthyroidism and protect the thyroid gland from radiation, but it does not help lower serum potassium levels.
Choice B rationale
Lactulose is a laxative used to treat constipation and hepatic encephalopathy, but it does not affect serum potassium levels.
Choice C rationale
Sodium polystyrene sulfonate is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, thereby lowering serum potassium levels.
Choice D rationale
Acetylcysteine is used as a mucolytic agent and to treat acetaminophen overdose, but it does not have any effect on serum potassium levels.
