Question

When do healthcare professionals follow transmission-based precautions?

1) when a patient is known to be immune to an infectious disease
2) when a patient is known to have a particular infectious disease
3) when standard-based precautions have been exhausted
4) when standard-based precautions have failed

Answer 1

Healthcare professionals follow transmission-based precautions when a patient is known to have a particular infectious disease. These precautions are additional measures taken on top of standard precautions to prevent the transmission of specific pathogens.

Step-by-step explanation:

Healthcare professionals follow transmission-based precautions when a patient is known to have a particular infectious disease. These precautions are additional measures taken on top of standard precautions to prevent the transmission of specific pathogens. Standard precautions include hand hygiene, wearing gloves, and using personal protective equipment (PPE) when necessary. Transmission-based precautions are used when there is an increased risk of specific infections spreading, such as airborne, droplet, or contact transmission.
