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?
Potassium 4.6 mEq/L.
Calcium 8 mg/dL.
Magnesium.1 mEq/L.
Sodium 150 mEq/L.
The Correct Answer is A
Sodium polystyrene sulfonate is a medication used to treat high levels of potassium in the blood.
A potassium level of 4.6 mEq/L is within the normal range, indicating that the medication has been effective in reducing high levels of potassium in the blood.
Choice B is wrong because Calcium 8 mg/dL, is not the correct answer because it measures the level of calcium in the blood and is not specifically related to sodium polystyrene sulfonate therapy.
Choice C is wrong because Magnesium.1 mEq/L, is not the correct answer because it measures the level of magnesium in the blood and is not specifically related to sodium polystyrene sulfonate therapy.
Choice D is wrong because Sodium 150 mEq/L, is not the correct answer because it measures the level of sodium in the blood and is not specifically related to sodium polystyrene sulfonate therapy.
