An infection control nurse is teaching a class about transmission of infectious agents. The nurse should include that which of the following diseases is transmitted via airborne transmission?

A. An N-95 respirator is designed to filter out airborne particles and is used primarily for protection against airborne diseases such as tuberculosis or certain respiratory infections like COVID-19. It is not necessary for contact precautions unless there is also a risk of airborne transmission.

B. Goggles protect the eyes from splashes, sprays, or droplets of infectious material. They are not typically required for routine contact precautions unless there is a risk of splashes or sprays to the eyes.
C. Gloves are essential for contact precautions. They protect the nurse's hands from direct contact with potentially infectious material on the client's bed linen or any contaminated surfaces. Gloves should be worn when handling soiled linen and removed and discarded appropriately after use.
D. A face shield provides full-face protection against splashes, sprays, or splatters of infectious material. It is particularly useful when there is a risk of exposure to bodily fluids or during procedures that may generate splashes. While not always required for routine contact precautions, it may be used depending on the specific situation, such as when cleaning surfaces heavily contaminated with body fluids.

A. This disease is caused by the varicella-zoster virus and is transmitted via airborne particles. When an infected person coughs or sneezes, the virus can be inhaled by others.

B. This bacterium causes severe diarrhea and colitis. It is primarily transmitted through contact with contaminated surfaces or feces, not through the air.
C. Measles is a highly contagious viral disease that spreads through airborne transmission. The virus can linger in the air for up to two hours after an infected person coughs or sneezes.
D. This bacterium can cause various infections, including skin infections and pneumonia. It is mainly spread through direct contact with an infected person or contaminated surfaces, not through the air.
E. Caused by the bacterium Mycobacterium tuberculosis, TB is transmitted through airborne particles. When a person with active TB coughs, sneezes, or talks, the bacteria can be inhaled by others.
