A nurse who provides weekly care in a homeless shelter has unknowingly inhaled airborne Mycobacterium tuberculosis and has subsequently developed latent tuberculosis infection. Which of the following is true of this nurse?
A) The nurse is likely asymptomatic.
B) The nurse is now immune to more severe tuberculosis infection.
C) The nurse can spread tuberculosis to others.
D) The nurse has active tuberculosis infection.

if a nurse who provides weekly care in a homeless shelter has unknowingly inhaled airborne Mycobacterium tuberculosis and has subsequently developed latent tuberculosis infection then it is TRUE that "The nurse is likely asymptomatic."

Explanation:

for us to be able to understand this question we need to know what the key terms are such as;

Mycobacterium tuberculosis(M. tb) this is a species of pathogenic bacteria in the family Mycobacteriaceae and it causes tuberculosis. It was First discovered by Robert Koch, M. tuberculosis in 1882.

Latent tuberculosis infection (LTBI) this is a state of persistent immune response to stimulation by Mycobacterium tuberculosis antigens without evidence of clinically manifested active TB. this is a state where someone is infected but the symptoms do not show.

Asymptomatic : this simply means showing no symptoms of the disease.

so by all the basis above we can conclude that the nurse is likely asymptomatic.

A) The nurse is likely asymptomatic, associated with the latent period.

Explanation:

Specifically the latent tuberculosis infections period  refers to the period  of antigen-antibody reaction where the body immune system  continually  reacts    to the stimulation by  antigens  of  mycobacterium tuberculosis. However because the immune system can still subdue the bacterium antigenic effects, no clinically manifested  signs or symptoms  of active TB is  observed. The stage of no signs and symptoms is called asymptomatic.
