Multiple Choice

Tuberculosis can affect other parts of the body, not just the lungs.

TB can spread beyond the lungs because the bacteria can travel through the blood or lymphatic system. While the lungs are the most common site, extrapulmonary TB can involve lymph nodes, the spine, meninges, kidneys, liver, and other organs, or occur as disseminated disease. Because of this, the statement that TB can affect other parts of the body, not just the lungs, is true. The other options don’t fit: TB does not have to be limited to the lungs, so false is incorrect, and the knowledge that extrapulmonary TB occurs means unknown isn’t the right choice.
