This document discusses tuberculosis (TB), including its causes, types, symptoms, diagnosis, and treatment. TB is an infectious disease caused by the bacterium Mycobacterium tuberculosis, which most commonly affects the lungs. It can be transmitted through inhalation of airborne droplets from an infected person. Diagnosis involves tests like tuberculin skin tests, chest x-rays, and bacterial studies. Treatment consists of a combination of antibiotics taken for 6-9 months to prevent drug resistance. Nursing care focuses on improving breathing, preventing transmission, maintaining nutrition, and ensuring compliance with the medication regimen.
