A nurse is evaluating whether the drug sodium polystyrene sulfonate (Kayexalate)is exerting the desired therapeutic effect for a client diagnosed with chronic kidney disease (CKD). Which therapeutic effect should the nurse anticipate from this medication?
A)Increased serum sodium
B)Increased stool excretion
C)Decreased urine specific gravity
D)Decreased serum potassium

Question

A)The client with CKD is unable to excrete potassium. Therefore, the drug sodium polystyrene sulfonate (Kayexalate)is used in order to exchange sodium for potassium in the large intestine, resulting in decreased serum potassium levels. Although the client might have increased stools, the therapeutic effectiveness of the drug is measured by monitoring the serum potassium. This drug does not affect either the serum sodium level or the urine specific gravity.
