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?
"Granulomas are formed by the immune system to encapsulate and destroy TB bacteria."
"Granulomas are clusters of active TB bacteria in the lungs."
"TB bacteria do not interact with the immune system within granulomas."
"Granulomas are the primary site of TB bacteria replication."
The Correct Answer is A
A) Correct. Granulomas are structures formed by the immune system in an attempt to encapsulate and contain TB bacteria, preventing their spread and aiding in their destruction.
B) Incorrect. Granulomas are not clusters of active TB bacteria; they are the body's response to containing the bacteria.
C) Incorrect. TB bacteria interact with the immune system within granulomas, leading to the formation of these structures.
D) Incorrect. Granulomas are not the primary site of TB bacteria replication; instead, they are formed to limit bacterial replication and spread.

B) Incorrect. The duration of TB treatment is determined by the specific regimen and is not solely related to the number of medications.
C) Incorrect. Multiple medications in TB treatment may target different aspects of TB bacteria, but the primary purpose is to reduce the risk of drug resistance.
D) Correct. Using multiple medications in combination therapy makes it more difficult for TB bacteria to develop resistance to all drugs simultaneously, helping to prevent drug-resistant TB.
Correct Answer is B
Explanation
A) Incorrect. A complete blood count (CBC) may reveal abnormalities associated with TB, but it does not directly confirm the presence of Mycobacterium tuberculosis in sputum samples.
B) Correct. Polymerase chain reaction (PCR) is a molecular test that can detect the genetic material of Mycobacterium tuberculosis in sputum samples, providing a confirmatory diagnosis.
C) Incorrect. The tuberculin skin test (TST) is a screening test for TB infection, not a test for confirming active disease in sputum samples.
D) Incorrect. Gram stain is a laboratory technique used to visualize the characteristics of bacterial cells but is not specific for Mycobacterium tuberculosis.
