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: A
Rationale:
Rationale: The correct answer is A because sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, thus lowering potassium levels. A normal potassium level of 4.6 mEq/L indicates the medication has been effective.
Choices B, C, and D are incorrect as they do not directly relate to the action of sodium polystyrene sulfonate in lowering potassium levels.
