A nurse is caring for a patient who has tuberculosis (TB). What statement by the nurse would be most appropriate to educate the patient and family about this condition?

Choice A reason: This statement by the nurse would not be appropriate to educate the patient and family about TB, as it incorrectly describes the infectious agent and mode of transmission for this condition. TB is not caused by a virus or spread through direct contact with skin lesions or respiratory droplets.

Choice B reason: This statement by the nurse would be most appropriate to educate the patient and family about TB, as it accurately describes the infectious agent and mode of transmission for this condition. TB is caused by a bacterium called Mycobacterium tuberculosis that can spread through inhalation of small droplets that remain in the air for long periods of time after an infected person coughs, sneezes, or speaks.

Choice C reason: This statement by the nurse would not be appropriate to educate the patient and family about TB, as it incorrectly describes the infectious agent and mode of transmission for this condition. TB is not caused by a fungus or spread through contact with soil or plants that are contaminated with spores.

Choice D reason: This statement by the nurse would not be appropriate to educate the patient and family about TB, as it incorrectly describes the infectious agent and mode of transmission for this condition. TB is not caused by a parasite or spread through ingestion of contaminated food or water.

Choice A reason: This is not the correct answer, as gloves and gown are not sufficient PPE to wear when entering the room of a patient who has measles. Gloves protect the nurse's hands from exposure to blood or body fluids, and gown protects the nurse's clothing and skin from contamination by blood or body fluids, but they do not protect the nurse's respiratory tract from exposure to airborne droplets that contain the measles virus.

Choice B reason: This is not the correct answer, as gloves and mask are not sufficient PPE to wear when entering the room of a patient who has measles. Gloves protect the nurse's hands from exposure to blood or body fluids, and mask protects the nurse's mouth and nose from exposure to large droplets that are generated by coughing, sneezing, or talking, but they do not protect the nurse's respiratory tract from exposure to small droplets that remain in the air for long periods of time and can be inhaled by others.

Choice C reason: This is not the correct answer, as gloves and eye protection are not sufficient PPE to wear when entering the room of a patient who has measles. Gloves protect the nurse's hands from exposure to blood or body fluids, and eye protection protects the nurse's eyes from exposure to splashes or sprays of blood or body fluids, but they do not protect the nurse's respiratory tract from exposure to airborne droplets that contain the measles virus.

Choice D reason: This is the correct answer, as gloves and respirator are the appropriate PPE to wear when entering the room of a patient who has measles. Gloves protect the nurse's hands from exposure to blood or body fluids, and respirator protects the nurse's respiratory tract from exposure to airborne droplets that contain the measles virus. A respirator is a device that filters out at least 95% of airborne particles and fits tightly around the face.
