19
Q

What is sequencing?

A

20
Q

When are contact precautions used??

A

When there is a risk of transmission by direct or indirect contact

21
Q

When are droplet precautions used?

A

When there is a risk of transmission by respiratory droplets

22
Q

When are airborne precautions used?

A

When there is a risk of transmission by infectious agents by the airborne route

23
Q

What is the difference between airborne and droplet precautions?

A

Airborne travels in the air and can travel very far whereas droplet is caught in closer contact and breathe in the droplets

24
Q
