What are Transmission-Based Precautions used for?

Transmission-Based Precautions are specifically designed to prevent the spread of infectious diseases when a patient is known or suspected to be contagious. These precautions go beyond standard infection control practices and are implemented based on the mode of transmission of the infectious agent, which may be airborne, droplet, or contact.

When a patient has a known or suspected contagious disease, healthcare providers need to take additional measures to protect themselves, other patients, and visitors from potential infection. This may include the use of personal protective equipment (PPE), isolating the patient, and following specific protocols during patient care.

The other options do not accurately capture the purpose of Transmission-Based Precautions. For example, they are not meant for preventing the transmission of all diseases indiscriminately, applying to healthy individuals, or routine medical check-ups where a patient has no known infection risk. Thus, the focus on patients with known or suspected contagious diseases is what makes this option the correct one in the context of Transmission-Based Precautions.
