A nurse is teaching a newly licensed nurse about administering sodium polystyrene sulfonate to a client. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

A. "I should monitor the client's electrolytes.": Sodium polystyrene sulfonate (Kayexalate) exchanges sodium for potassium in the intestines, lowering serum potassium levels. Monitoring electrolytes is essential to evaluate therapeutic effectiveness and prevent imbalances such as hypokalemia or hypernatremia. B. "Antacids can be taken with this medication.": Antacids containing calcium or magnesium can interfere with the medication’s ion-exchange mechanism and increase the risk of systemic absorption, leading to metabolic complications. They should be avoided. C. "I should administer this medication intravenously.": Sodium polystyrene sulfonate is administered orally or rectally, not intravenously. IV administration would be unsafe and is contraindicated due to the drug’s formulation and mechanism. D. "This medication is safe to take with sorbitol.": Concomitant use with sorbitol is avoided because it increases the risk of intestinal necrosis. These agents should not be used together due to their additive gastrointestinal effects.
