A patient suspected of having Tuberculosis is in the emergency department. Which isolation precaution is most appropriate to prevent the spread of the disease?
Droplet Precautions
Contact Precautions
Airborne Precautions
Standard Precautions
Tuberculosis is an airborne infectious disease. Patients suspected or confirmed to have TB should be placed in airborne isolation precautions, which include placing the patient in a negative pressure room and using respiratory protective equipment such as N95 respirators. Contact precautions involve the use of gloves and gowns and are more appropriate for diseases spread by direct contact. Droplet precautions are not sufficient for TB as the infectious agent can remain suspended in the air and may transmit over greater distances than droplets. Reverse isolation is used to protect immunocompromised patients from getting an infection, not to prevent the spread of disease from an infected patient.
