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)]
Serum ammonia level of 30 Mcg/dL (17.62 Mcmol /dL).
Serum potassium level of 3.8 mEq/L (3.8 mmol/L).
Serum glucose level of 120 mg/dL (6.7 mmol/L).
Hemoglobin level of 13.5 g/dL (135 g/L).
The Correct Answer is B
Choice A rationale: Serum ammonia levels are not relevant to the effectiveness of sodium polystyrene sulfonate in treating hyperkalemia.
Choice B rationale: Sodium polystyrene sulfonate is a medication used to treat hyperkalemia (high potassium levels). A serum potassium level of 3.8 mEq/L falls within the normal reference range (3.5 to 5.0 mEq/L), indicating that the medication has been effective in promoting the excretion of potassium and reducing hyperkalemia.
Choice C rationale: Serum glucose levels are not relevant to the effectiveness of sodium polystyrene sulfonate in treating hyperkalemia.
Choice D rationale: Hemoglobin levels are not relevant to the effectiveness of sodium polystyrene sulfonate in treating hyperkalemia.

Correct Answer is D
Explanation
Choice A rationale: This instruction is not directly related to spironolactone use or hyperaldosteronism. Excessive bruising may be relevant in some situations but not specifically for this scenario.
Choice B rationale: While heart failure patients are often advised to reduce their sodium intake, the use of a salt substitute (potassium-based) would be contraindicated in this case due to the risk of hyperkalemia.
Choice C rationale: This instruction is not directly related to spironolactone use or
hyperaldosteronism. It may be relevant for sun protection, but it is not a priority in this context.
Choice D rationale: Spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium while excreting sodium and water. Since the client has heart failure (HF), there is a risk of hyperkalemia (high potassium levels) associated with spironolactone use. To prevent this, the nurse should instruct the client to limit their intake of high-potassium foods, such as bananas, oranges, tomatoes, spinach, and other potassium-rich foods.
