Final answer:
Airborne precautions are used for diseases such as tuberculosis, measles, and chickenpox.
Step-by-step explanation:
Airborne precautions are used for diseases that can be spread through the air, typically through respiratory droplets or aerosols. The diseases for which we use airborne precautions include:
- Tuberculosis: TB bacteria are spread in the air when infected individuals cough, sneeze, or spit.
- Measles: Measles is an airborne infectious disease caused by a virus and spreads when someone sneezes or coughs microscopic pathogens into the air.
- Chickenpox: Chickenpox is highly contagious and gains entry through the respiratory system, causing rashes and fevers.
Therefore, the correct answer is 4) All of the above.
