What is true about Transmission-Based Precautions?

1. They are the same as standard precautions

2. They are practiced in addition to standard precautions

3. They are only for airborne diseases

4. They do not involve hand hygiene

The correct answer is: They are practiced in addition to standard precautions

Transmission-Based Precautions are specifically designed to prevent the spread of infectious agents that are transmitted in specific ways, such as through contact, droplets, or airborne routes. These precautions are used in addition to standard precautions, which are universal measures recommended for all patients to reduce the risk of transmission of infections. Standard precautions include practices like hand hygiene, the use of personal protective equipment (PPE), and safe injection practices, and they serve as the foundation for preventing infections in healthcare settings. By implementing Transmission-Based Precautions in conjunction with standard precautions, healthcare providers can effectively control and prevent the spread of infections, particularly in situations where patients are suspected or confirmed to have certain infectious diseases that require additional safety measures. This layered approach ensures not only the safety of the healthcare workers and patients but also helps in managing outbreaks effectively, as it tailors the interventions based on the transmission routes of the specific pathogens in question.
