A nurse is preparing to report laboratory results to the provider for a client who is taking clozapine. For which of the following findings does the nurse anticipate a prescription to discontinue clozapine?

Magnesium 2.5 mEq/L (1.3 to 2.1 mEq/L)

Potassium 5.4 mEq/L (3.5 to 5 mEq/L)

WBC 2,500/mm³ (5,000 to 10,000/mm³)

Sodium 134 mEq/L (136 to 145 mEq/L)

Answer and Explanation

The Correct Answer is C

A. Magnesium 2.5 mEq/L: A magnesium level slightly above the normal range does not indicate an immediate need to discontinue clozapine, as this level is not related to the adverse effects of the drug.

B. Potassium 5.4 mEq/L: While elevated potassium levels can pose a health risk, this is not a direct indicator to discontinue clozapine. Potassium levels can be managed with other interventions.

C. WBC 2,500/mm³: Clozapine carries a risk of agranulocytosis, a condition where the white blood cell (WBC) count becomes dangerously low, leading to severe infection risk. A WBC count of 2,500/mm³ is below the normal range and indicates the need to discontinue clozapine immediately.

D. Sodium 134 mEq/L: A slightly low sodium level is not typically related to clozapine use and does not warrant discontinuation of the medication.

C. Nitrofurantoin should not be crushed, as it can affect the medication's absorption and effectiveness.
