A nurse is explaining the pathophysiology of tuberculosis (TB) to a group of nursing students. Which statement accurately describes the role of granulomas in TB infection?

A) Correct. Using multiple drugs to treat TB reduces the risk of drug resistance development, as it targets the bacteria from different angles and makes it harder for them to become resistant to one or more drugs.

B) Incorrect. While using multiple drugs may help manage side effects by spreading the burden of treatment, the primary purpose is to prevent drug resistance.

C) Incorrect. Shortening the treatment duration is a goal, but it is not the primary purpose of using multiple drugs.

D) Incorrect. Although improving patient compliance is important, the primary purpose of using multiple drugs is to reduce drug resistance.

QUESTIONS

A) Incorrect. While multiple antibiotics may lead to symptom relief, the primary goal is to prevent drug resistance.

B) Correct. Combination therapy with multiple antibiotics is used to reduce the risk of drug-resistant TB, as it makes it more difficult for the bacteria to develop resistance to all drugs simultaneously.

C) Incorrect. Multiple antibiotics are used to target different aspects of TB treatment, not different types of TB bacteria.

D) Incorrect. While using multiple antibiotics can help manage side effects, the primary reason is to prevent drug resistance.
