In addition to hand hygiene, what is another key practice for infection prevention?

Implementing isolation precautions is a critical practice for infection prevention because it minimizes the risk of spreading infectious agents between patients, healthcare workers, and visitors. Isolation precautions involve separating individuals who are known or suspected to be infected from those who are healthy and can help prevent cross-contamination in healthcare settings. This can include using personal protective equipment (PPE), designating special areas for isolated patients, and employing specific cleaning protocols to ensure that contaminated surfaces do not pose a risk to others.

The other options do not effectively contribute to infection prevention in the same way. For instance, using antibiotics for all patients can lead to antibiotic resistance, which is a significant public health concern that complicates infection treatment. Limiting visitor access is a more restrictive measure that may have implications for patient well-being without necessarily reducing infection risk. Increasing patient room density may actually heighten the potential for infection transmission by bringing more individuals into closer proximity, which goes against the principles of infection control.
