A nurse is assisting in the care of a client suspected of having a tuberculosis infection. Which of the following personal protective equipment should the nurse wear when in the client's room?

A. Gloves: Gloves are important for contact precautions but are not sufficient protection against airborne infections like tuberculosis. Tuberculosis spreads through respiratory droplets that remain suspended in the air, requiring specialized respiratory protection. B. Gown: A gown is generally used when there is a risk of direct contact with infectious material. While gowns are important for many isolation precautions, they do not protect against airborne transmission of tuberculosis. C. Dosimeter badge: A dosimeter badge measures exposure to radiation, not infectious agents. It is used in environments with radiologic procedures and is unrelated to protecting against infectious diseases like tuberculosis. D. N95 respirator: An N95 respirator is specifically designed to filter airborne particles, including Mycobacterium tuberculosis. It fits tightly around the face and provides the necessary protection against inhaling infectious airborne pathogens in the client’s environment.
