A client is in the initial treatment phase for tuberculosis.
Which of the following antitubercular drugs would the nurse expect the client to receive during this phase?

Choice A rationale:

Isoniazid Isoniazid is one of the first-line drugs used in the initial treatment phase of tuberculosis (TB). It is a key component of the standard regimen for TB treatment. Isoniazid is highly effective against Mycobacterium tuberculosis, the bacterium responsible for TB, and it plays a critical role in the initial phase of treatment to rapidly reduce the bacterial load.

Choice B rationale:

Ciprofloxacin Ciprofloxacin is not a first-line drug for the treatment of tuberculosis. While it has antibacterial properties, it is not considered one of the primary agents for TB treatment. It is more commonly used to treat other types of bacterial infections, such as urinary tract infections.

Choice C rationale:

Gentamycin Gentamycin is not typically used as a first-line treatment for TB. It is reserved for specific situations, such as drug-resistant TB cases, and is not part of the standard initial treatment regimen for TB.

Choice D rationale:

Clindamycin Clindamycin is not a first-line drug for the treatment of tuberculosis. It is primarily used to treat anaerobic bacterial infections and is not a standard part of TB treatment protocols.

Choice A rationale:

Sulfonamides can increase the risk of crystalluria, which may lead to kidney stones. Adequate fluid intake can help dilute the urine and reduce the risk of crystalluria and kidney stone formation. This is a relevant and appropriate response by the nurse.

Choice B rationale:

Sulfonamides can make the skin more sensitive to sunlight, increasing the risk of sunburn. However, increasing fluid intake is primarily to prevent kidney stone formation, not a reaction to sunlight.

Choice C rationale:

While maintaining adequate hydration does help prevent dehydration, this answer does not directly address the potential side effects or risks associated with sulfonamide use. It is a bit too general and doesn't provide specific information related to the medication.

Choice D rationale:

Sulfonamides can affect blood counts in some cases, but maintaining adequate fluid intake is not primarily related to preventing low blood counts. It's more about mitigating the specific side effects associated with sulfonamide use, such as crystalluria and kidney stones.
