What client statement indicates understanding about tuberculosis (TB) transmission?

1. "I can develop TB by breathing in the infection."

2. "After exposure, I could develop TB within 5 days."

3. "A positive reaction to a TB test means I'm currently infected."

4. "I need to wear a mask in my house if I become infected."

The correct answer is: "I can develop TB by breathing in the infection."

The statement expressing understanding about tuberculosis (TB) transmission is that the individual can develop TB by breathing in the infection. TB is primarily spread through the air from person to person. When someone with active TB disease in their lungs or throat coughs, sneezes, speaks, or sings, they release tiny droplets that contain the bacteria into the air. If another person inhales these droplets, they can become infected. This highlights the airborne nature of TB transmission. Other statements reflect common misconceptions. For instance, while exposure to TB can lead to infection, the development of symptoms or the disease itself typically occurs after several weeks to months, rather than within 5 days. Additionally, a positive reaction to a TB skin test or blood test indicates exposure to the TB bacteria, but it does not confirm an active infection; further evaluation is needed. Though wearing a mask at home can be a precautionary measure when a person is infected with active TB, it is not a definitive statement of understanding regarding the transmission process itself.
