A client asks a nurse why tuberculosis (TB) can remain latent in the body for many years without causing symptoms. What is the nurse's best explanation?
"TB bacteria are dormant and do not replicate in the body during latent infection."
"The immune system immediately eliminates TB bacteria during the latent phase."
"Latent TB infection occurs in the lungs, where it does not cause symptoms."
"TB bacteria actively multiply in the body but at a very slow rate during latency."
The Correct Answer is A
A) Correct. During latent TB infection, TB bacteria are in a dormant state and do not actively replicate or cause symptoms. They can become active and multiply if the immune system weakens.
B) Incorrect. While the immune system can control TB bacteria during latency, it does not immediately eliminate them.
C) Incorrect. Latent TB infection can occur in various parts of the body, not just the lungs, and it typically does not cause symptoms.
D) Incorrect. TB bacteria in latent infection are in a dormant state and do not actively multiply, although they remain viable.
