A nurse is teaching a client who has tuberculosis and is to start medication therapy with isoniazid, rifampin, and pyrazinamide. Which of the following instructions should the nurse include?
A.
“Expect your sputum cultures to be negative after 6 months of therapy.”
B.
“Drink at least 8 ounces of water when you take the pyrazinamide tablet.”
C.
“Provide a sputum specimen every 2 weeks to the clinic for testing.”
D.
“Take isoniazid with an antacid.”
The correct answer and Explanation is :
The correct answer is C. “Provide a sputum specimen every 2 weeks to the clinic for testing.”
Explanation
For a patient starting tuberculosis (TB) medication therapy, regular monitoring and adherence to specific instructions are crucial for effective treatment and preventing the spread of the disease. Here’s a breakdown of why option C is the most appropriate advice:
Sputum Specimen Testing:
TB treatment usually involves a combination of drugs, such as isoniazid, rifampin, and pyrazinamide, over several months. Regular monitoring through sputum tests is essential to assess the effectiveness of the treatment and to ensure the bacteria are being effectively eliminated. Typically, patients are asked to provide sputum specimens every 2 to 4 weeks during the initial phase of treatment. This helps in determining if the bacteria are still present and if the treatment needs to be adjusted.
Other Options Explained:
A. “Expect your sputum cultures to be negative after 6 months of therapy.”
Sputum cultures may not necessarily be negative after 6 months of therapy. The goal is to achieve a negative culture result, but this can vary depending on individual response and adherence to the medication regimen. The patient should follow up regularly with their healthcare provider for proper evaluation and testing.
B. “Drink at least 8 ounces of water when you take the pyrazinamide tablet.”
While hydration is important, the primary concern with pyrazinamide is the potential for hepatotoxicity (liver damage). Drinking 8 ounces of water is not a specific requirement for pyrazinamide; however, patients should be monitored for liver function and informed about signs of liver problems.
D. “Take isoniazid with an antacid.”
Isoniazid should not be taken with an antacid, as antacids can interfere with the absorption of isoniazid. It is generally recommended to take isoniazid on an empty stomach, at least 1 hour before or 2 hours after meals, and to avoid taking it with antacids.
Thus, option C is the most pertinent instruction, as regular sputum testing is critical for monitoring the progress of TB treatment.
