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. Gown: Gowns are typically used to protect against contact with infectious body fluids or contaminated surfaces. Tuberculosis is primarily transmitted via airborne droplets, so gowns are not required for routine care of a client with suspected TB. B. Gloves: Gloves protect against direct contact with infectious materials or bodily fluids. While gloves may be used during procedures involving secretions, they are not the primary protective equipment for preventing inhalation of airborne TB particles. C. Dosimeter badge: Dosimeter badges monitor exposure to ionizing radiation and are irrelevant in the context of airborne infectious diseases like tuberculosis. Wearing a dosimeter does not protect against TB transmission. D. N95 respirator: An N95 respirator is specifically designed to filter airborne particles, including Mycobacterium tuberculosis. Nurses must wear an N95 respirator when entering the room of a client with suspected or confirmed TB to prevent inhalation of infectious droplets.
