A nurse is caring for a patient who has Clostridium difficile infection (CDI). What type of transmission-based precautions should the nurse implement for this patient?

Choice A reason: This action should be taken by the nurse to prevent cross-contamination, as it helps protect the nurse and other patients from exposure to MRSA, which can be transmitted through direct or indirect contact with infected skin or wounds.

Choice B reason: This action should be taken by the nurse to prevent cross-contamination, as it helps prevent the transmission of MRSA, which can survive on surfaces or objects for long periods of time.

Choice C reason: This action should be taken by the nurse to prevent cross-contamination, as it helps eliminate MRSA, which can be resistant to many disinfectants and antibiotics.

Choice D reason: This is the correct answer, as all of the above actions should be taken by the nurse to prevent cross-contamination. MRSA is a serious and potentially life-threatening infection that can cause skin and soft tissue infections, bloodstream infections, pneumonia, or surgical site infections.

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.
