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).

Answer and Explanation

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 A

Explanation

A:The primary therapeutic effect of epoetin alfa is to stimulate erythropoiesis, leading to an increase in hemoglobin levels. An increase to 12 g/dL demonstrates that the medication is effectively treating the anemia caused by CKD. Monitoring hemoglobin levels is the most objective and reliable indicator of the medication’s effectiveness.

B: While these subjective improvements can indicate an overall improvement in anemia-related symptoms, they are not the best or most definitive measure of the medication's effectiveness. Objective data, such as hemoglobin levels, provide more concrete evidence.

C: Increased consumption of iron-rich foods is beneficial for clients with anemia, but it is not a direct indicator of the effectiveness of epoetin alfa. Dietary changes can support overall health but do not provide evidence of the medication's impact on hemoglobin levels.

D: Taking concurrent iron therapy is common for clients receiving epoetin alfa, as iron is necessary for the production of red blood cells. However, the absence of adverse effects does not directly indicate the effectiveness of epoetin alfa in increasing hemoglobin levels.
