Universal precautions treat which materials as potentially infectious?

Universal precautions are a set of guidelines designed to protect healthcare workers and patients from the transmission of infectious diseases. The principles of universal precautions state that all human blood and certain other potentially infectious materials should be treated as though they are infectious, regardless of a person's known health status.

This includes not only human blood but also other body fluids that may contain blood, such as semen, vaginal secretions, saliva in dental procedures, and any materials that may be contaminated with these fluids. By adopting this comprehensive approach, healthcare settings can reduce the risk of exposure to bloodborne pathogens, such as HIV and Hepatitis B and C.

Thus, the correct response reflects the broad scope of materials classified under universal precautions, recognizing the potential risk posed by all human blood and potentially infectious materials. This understanding is vital for maintaining safety and preventing the spread of infectious diseases in healthcare environments.
