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.

Answer and Explanation

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.

Correct Answer is C

Explanation

First, convert the client’s weight from pounds to kilograms: 121 lb /.2 = 55 kg. Then, calculate the dose in mg: 1 mg/kg * 55 kg = 55 mg.

Finally, use the ratio of available enoxaparin to calculate the volume to administer: (55 mg / 60 mg) * 0.6 mL = 0.55 mL.

Rounded to the nearest tenth, this is 0.6 mL.

Choice A is wrong because it is less than the calculated dose of 0.6 mL.

Choice B is wrong because it is equal to the calculated dose of 0.6 mL but not rounded to the nearest tenth.

Choice D is wrong because it is greater than the calculated dose of 0.6 mL.

A. Creatinine.5 mg/dL. B. Potassium 4.2 mEq/L. C. BUN 18 mg/dL. D. Sodium 139 mEq/L.

Correct Answer is A

Explanation

Cyclosporine is an immunosuppressant medication that can have nephrotoxic effects.

A creatinine level of.5 mg/dL is above the normal range and may indicate impaired kidney function.

The nurse should report this value to the provider for further evaluation.

Choice B is wrong because Potassium 4.2 mEq/L, is not the correct answer because it falls within the normal range for potassium levels in the blood.

Choice C is wrong because BUN 18 mg/dL, is not the correct answer because it falls within the normal range for blood urea nitrogen levels.

Choice D is wrong because Sodium 139 mEq/L, is not the correct answer because it falls within the normal range for sodium levels in the blood.
