Question 11

Tuberculosis is spread by airborne droplets spread by coughing.

Tuberculosis is primarily transmitted through the air when an infected person coughs, sneezes, or talks, releasing droplets that contain the bacteria into the environment.

A) bacteria entering the urethra

This option is incorrect because tuberculosis is not transmitted through the urinary tract. The primary route of transmission is respiratory, not through the urethra, which is unrelated to tuberculosis spread.

B) insufficient fluid intake

This choice is also incorrect as insufficient fluid intake does not play a role in the transmission of tuberculosis. While hydration is important for overall health, it does not affect the spread of the disease itself.

C) airborne droplets spread by coughing

This option is correct as it accurately describes the primary method of transmission for tuberculosis. Infected individuals release bacteria into the air through respiratory droplets, which can then be inhaled by others, leading to new infections.

D) lack of proper rest

This option is incorrect because lack of rest does not facilitate the transmission of tuberculosis. While proper rest is important for maintaining a healthy immune system, it does not relate to how tuberculosis is spread from person to person.

Conclusion

The correct answer is C because it correctly identifies the method of transmission for tuberculosis, which is primarily through airborne droplets from an infected person's respiratory activities. Options A, B, and D fail to address the actual transmission mechanism, thus confirming C as the only accurate choice regarding the spread of tuberculosis.
