Lactulose

Sevelamer

Answer and Explanation

The Correct Answer is C

A. Lactulose: Lactulose is used to reduce blood ammonia levels in hepatic encephalopathy, not to reduce potassium levels. It is not appropriate for treating hyperkalemia.

B. Sevelamer: Sevelamer is a phosphate binder used in clients with chronic kidney disease to lower serum phosphorus levels, not potassium. It is not appropriate for treating hyperkalemia.

C. Sodium polystyrene: Sodium polystyrene (Kayexalate) is a cation-exchange resin used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestine, promoting the excretion of potassium. This is the correct medication to administer for a serum potassium level of 6.8 mEq/L.

D. Darbepoetin alfa: Darbepoetin alfa is a synthetic erythropoietin used to treat anemia associated with chronic kidney disease. It is not used to treat hyperkalemia.
