Quizplus · Accepted Answer

Sodium polystyrene sulfonate (Kayexalate) is a medication that works by exchanging sodium ions for potassium ions in the large intestine, which results in decreased serum potassium levels. It does not affect serum sodium levels, urine specific gravity, or stool excretion. Therefore, the anticipated therapeutic effect from this medication would be a decrease in serum potassium levels for a patient with chronic kidney disease.
