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.

Correct Answer is A

Explanation

A. Frequent sputum tests may be needed to monitor the effectiveness of isoniazid, particularly in assessing the resolution of tuberculosis infection.

B. Isoniazid is usually prescribed for a minimum of six months for tuberculosis treatment, not just a month. Thus, stopping after one month is incorrect.

C. Antacids containing aluminum should not be taken concurrently with isoniazid, as they can interfere with the absorption of the medication, reducing its effectiveness.

D. Constipation is not a common side effect of isoniazid. The more frequent side effects include peripheral neuropathy and liver toxicity, making this statement incorrect.

A. Respiratory rate 24/min B. Oral temperature 38.9° C (102° F) C. Blood pressure 118/78 mm Hg D. Apical pulse 50/min

Correct Answer is D

Explanation

A. A respiratory rate of 24/min is elevated and may suggest respiratory distress, but it is not a specific adverse effect of propranolol.

B. An oral temperature of 38.9° C (102° F) indicates fever, which is not a typical adverse effect of propranolol.

C. A blood pressure of 118/78 mm Hg is within normal limits and does not indicate an adverse effect of propranolol, which is often used to manage hypertension.

D. An apical pulse of 50/min indicates bradycardia, a known adverse effect of propranolol, which can occur due to its action on the heart rate.
