A client asks a nurse about the role of latent tuberculosis infection (LTBI) in the development of active TB disease. What information should the nurse provide?
"LTBI never progresses to active TB disease."
"The risk of LTBI progressing to active TB is higher in individuals with a strong immune system."
"LTBI can remain dormant for years and may progress to active TB if the immune system weakens."
"LTBI is the same as active TB disease and requires immediate treatment."
The Correct Answer is C
A) Incorrect. LTBI can progress to active TB disease if the immune system weakens or is compromised.
B) Incorrect. The risk of progression from LTBI to active TB is higher in individuals with weakened immune systems, not those with strong immune systems.
C) Correct. LTBI can remain dormant for years, and the risk of progression to active TB disease is higher when the immune system becomes compromised.
D) Incorrect. LTBI and active TB disease are distinct conditions, and LTBI does not always require immediate treatment. Treatment may be recommended for individuals at higher risk of progression to active disease.
