Extract:


Question 1 of 5

A nurse is reviewing the laboratory results of a client who received a dose of sodium polystyrene sulfonate. Which of the following findings should the nurse identify as an indication that the medication has been effective?

Correct Answer: D

Rationale: The correct answer is D: Potassium 4.6 mEq/L. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium excretion.
Therefore, a decrease in potassium level indicates that the medication has been effective in lowering potassium levels.
A: Calcium level is not affected by sodium polystyrene sulfonate.
B: Magnesium level is not a parameter directly affected by the medication.
C: Sodium level is not a parameter that the medication targets.
In summary, the decrease in potassium level is the key indicator of the effectiveness of sodium polystyrene sulfonate in treating hyperkalemia.
