Question 1 of 5

The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Glucose [Reference Range: 74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin (Hgb) [Reference Range: 12-16 g/dL (120-160 g/L)] Potassium (K+) [Reference Range: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Ammonia [Reference Range: Adult: 10 to 80 Mcg/dL (6 to 47 Mcmol/dL)]

Correct Answer: B

Rationale: Sodium polystyrene sulfonate treats hyperkalemia by binding potassium in the gut. A serum potassium level of 3.8 mEq/L (normal range) indicates effective reduction of potassium levels in AKI. Ammonia, glucose, and hemoglobin are not affected by this medication.
