A client develops pseudomembranous colitis secondary to fluoroquinolone therapy.
The nurse understands that this is the result of which organism?

Choice A rationale:

Long-term therapy is not typically used for household members and close associates of a client with TB. It is primarily used for treating active tuberculosis in the patient.

Choice B rationale:

Latent therapy is used to treat individuals who have latent TB infection but are not actively spreading the disease. It is not used for household members and close associates to prevent the spread.

Choice C rationale:

This is the correct answer. DOT (Directly Observed Therapy) therapy is a method used to ensure that patients with TB take their medications as prescribed. Household members and close associates may be asked to help ensure the patient's adherence to therapy by directly observing them take their medications, thus preventing the spread of the disease.

Choice D rationale:

Short-term therapy is not a specific term used in the context of TB treatment. The most appropriate choice for preventing the spread of TB among household members and close associates is DOT therapy.

Choice A rationale:

Monitoring for the appearance of adverse reactions is a crucial aspect of managing a patient with TB undergoing treatment. TB medications can have side effects, and early detection of adverse reactions is essential for timely intervention. Some common adverse effects of TB drugs include hepatotoxicity, peripheral neuropathy, and gastrointestinal disturbances. By closely monitoring the patient, the nurse can ensure prompt action if these side effects occur, improving the patient's overall care and safety.

Choice B rationale:

Monitoring the patient's vital signs every 24 hours may be part of standard nursing care, but when managing a patient with TB, the primary focus should be on monitoring for adverse reactions to the TB medications. Vital signs are important but not the most critical aspect of care in this specific situation.

Choice C rationale:

Assessing the patient's history of contacts is essential for identifying potential sources of TB transmission. However, it is more related to the initial assessment and diagnosis of TB rather than ongoing assessment during treatment. The primary focus during treatment is monitoring the patient's response to medication and any adverse reactions.

Choice D rationale:

Using Directly Observed Therapy (DOT) to administer TB drugs is a standard practice to ensure treatment adherence. However, ongoing assessment should focus on monitoring for adverse reactions and treatment effectiveness rather than the administration method, which is usually established at the beginning of treatment.
