A nurse is assisting with the admission of a client who has leukemia. Which of the following transmission precautions should the nurse implement?

Choice A reason: Placing a client with active pulmonary TB in a room with positive airflow is not recommended, as positive airflow would push potentially contaminated air into general circulation, risking the spread of TB. Instead, a room with negative airflow is appropriate to contain and remove contaminated air.

Choice B reason: Determining whether the client lives alone or with others is important for public health and contact tracing purposes. If the client lives with others, those individuals may need to be tested and monitored for TB as well.

Choice C reason: Using an alcohol-based hand cleaner is a standard practice unless hands are visibly soiled. If hands are visibly soiled, handwashing with soap and water is necessary.

Choice D reason: Reminding the client to cover their mouth with a tissue when coughing is a key measure to prevent the spread of TB, which is transmitted through airborne particles from coughs or sneezes.

Choice E reason: Antifungal medications are not used to treat TB, which is caused by a bacterium, not a fungus. The client should be instructed about taking anti-tuberculosis medications, not antifungals.

Choice A reason: Droplet precautions are used for diseases that are spread by large respiratory droplets produced by coughing, sneezing, or talking. Examples include influenza, pertussis, and mumps. However, tuberculosis is not spread through large droplets but through airborne particles that can remain suspended in the air for long periods.

Choice B reason: Airborne precautions are necessary for diseases that are transmitted by smaller droplets, which can be suspended in the air for extended periods and can be inhaled. Tuberculosis, particularly pulmonary or laryngeal tuberculosis with a productive cough, requires airborne precautions because the bacteria can be expelled into the air and inhaled by others. The nurse should initiate airborne precautions, which include placing the patient in a negative pressure room and using personal protective equipment such as N95 respirators.

Choice C reason: Contact precautions are used for infections that are spread by direct contact with the patient or the patient's environment. Examples include infections caused by multidrug-resistant organisms, scabies, and norovirus. Tuberculosis is not spread by direct contact, so contact precautions are not the primary method of prevention.

Choice D reason: Protective isolation, also known as neutropenic or reverse isolation, is used to protect immunocompromised patients from infections. It is not used for patients with tuberculosis, as the goal is to protect others from the tuberculosis bacteria, not to protect the patient from external infections.
