Review PN NCLEX Practice Test related questions and content

The nurse is evaluating the effectiveness of the medication regimen for a client with chronic kidney disease who is receiving sodium polystyrene sulfonate. It would indicate that the medication regimen has been effective if the client’s most recent laboratory test results indicate

  • A. an increase in the serum calcium level
  • B. an increase in the serum creatinine level
  • C. a decrease in the serum potassium level
  • D. a decrease in the serum phosphate level
Correct Answer: C

Rationale: Sodium polystyrene sulfonate treats hyperkalemia in chronic kidney disease by exchanging sodium for potassium in the gut, so a decreased potassium level indicates effectiveness. Calcium levels are not directly affected, and rising creatinine indicates worsening kidney function.
