A nurse is teaching a client who has a new prescription for isoniazid. Which of the following information should the nurse include in the teaching?

"You will need to have frequent sputum tests to monitor the effectiveness of the medication."

"You will be able to stop taking this medication after a month."

"You can take an antacid containing aluminum at the same time as this medication."

"You can expect to have constipation while taking this medication."

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

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.

A. Cataracts B. Hypertension C. Hypothyroidism D. Peptic ulcer disease

Correct Answer is D

Explanation

A. Cataracts are not a contraindication for cholinesterase inhibitors like neostigmine.

B. Hypertension is not a direct contraindication for cholinesterase inhibitor therapy, although caution may be exercised depending on the overall health status of the client.

C. Hypothyroidism is not contraindicated for cholinesterase inhibitors; however, it should be managed appropriately.

D. Peptic ulcer disease is a significant contraindication for cholinesterase inhibitors like neostigmine because these medications can increase gastric secretions and motility, potentially exacerbating ulcer conditions and leading to complications.
