A client asks a nurse about the differences between latent TB infection (LTBI) and active TB disease. Which statement by the nurse is correct?
"LTBI is not contagious, but active TB disease can be spread to others."
"Both LTBI and active TB disease are equally contagious to others."
"LTBI and active TB disease have the same symptoms and treatment."
"LTBI always progresses to active TB disease if left untreated."
The Correct Answer is A
A) Correct. LTBI is not contagious, as the bacteria are dormant and not actively causing illness. Active TB disease, on the other hand, is contagious and can be transmitted to others through respiratory droplets.
B) Incorrect. LTBI is not contagious, whereas active TB disease is contagious.
C) Incorrect. LTBI and active TB disease have different symptoms and treatment approaches. LTBI has no symptoms, while active TB disease presents with symptoms and requires treatment to prevent progression.
D) Incorrect. LTBI does not always progress to active TB disease. In fact, many individuals with LTBI do not develop active disease, but they are at risk, especially if their immune system becomes compromised.

C) Correct. Close contact with someone who has active TB disease is a significant risk factor for TB transmission, as the bacteria can be transmitted through respiratory droplets.
