A nurse is caring for a client receiving sodium polystyrene sulfonate (Kayexalate) for the treatment of chronic renal disease. The nurse should monitor for which therapeutic effect of sodium polystyrene sulfonate (Kayexalate)?
Decreased serum sodium
Decreased serum phosphorus
Decreased urine specific gravity
Decreased serum potassium
The Correct Answer is D
A. Decreased serum sodium: Kayexalate exchanges sodium for potassium, so sodium may actually increase.
B. Decreased serum phosphorus: Kayexalate does not directly affect phosphate levels.
C. Decreased urine specific gravity: Kayexalate does not influence urine output or concentration.
D. Decreased serum potassium: Kayexalate treats hyperkalemia by exchanging potassium ions for sodium in the intestines, lowering serum potassium.

B. Bananas: Bananas are high in potassium and commonly restricted in CKD to prevent hyperkalemia.
C. Green beans: Green beans are relatively low in potassium and generally safe for a renal diet.
D. Asparagus: Asparagus has moderate potassium levels but can be included in moderation depending on the client's labs.
E. Tomatoes: Tomatoes, especially in processed forms like sauce or juice, are high in potassium.
