What approach is indicated when a respiratory therapist treats all patients in the intensive care unit as if they have HIV and hepatitis?

The approach of treating all patients in the intensive care unit as if they have HIV and hepatitis is best described by standard precautions. This practice emphasizes the importance of consistently applying infection control measures to prevent the transmission of bloodborne and other pathogens, regardless of the patient's known status.

Standard precautions incorporate a range of strategies including hand hygiene, use of personal protective equipment (PPE) like gloves and masks, and safe handling of potentially contaminated materials. This method not only safeguards the healthcare providers but also helps protect patients from potential cross-contamination. By treating every patient with the assumption they could be infectious, the risk of spreading infections is minimized, creating a safer environment in the healthcare setting. This universal approach is crucial in intensive care units where patients may be more vulnerable and the risk of infection transmission is heightened.
