A nurse is implementing transmission-based precautions for a patient who has measles. What type of personal protective equipment (PPE) should the nurse wear when entering the patient's room?

Choice A reason: This factor may have contributed to the development of an HAI, as children have immature immune systems that make them more susceptible to infections.

Choice B reason: This factor may have contributed to the development of an HAI, as children may be exposed to other infected patients or health care workers who can transmit microorganisms through direct or indirect contact.

Choice C reason: This factor may have contributed to the development of an HAI, as children may use contaminated medical devices or equipment that can introduce microorganisms into their body, such as catheters, ventilators, or intravenous lines.

Choice D reason: This factor may have contributed to the development of an HAI, as children may contact environmental surfaces or objects that can harbor microorganisms, such as bed rails, tables, toys, or books.

Choice E reason: This factor may not have contributed to the development of an HAI, as CAIs are infections that are acquired outside of health care settings. However, CAIs may increase the risk of HAIs if they are not treated properly or if they cause complications.

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.
