What do universal (standard) precautions aim to prevent?

Transmission of bloodborne pathogens
Airborne infection spread
Foodborne illness outbreaks
Skin abrasions during treatment

The correct answer is: Transmission of bloodborne pathogens

Universal (standard) precautions are a set of guidelines designed to prevent the transmission of bloodborne pathogens in healthcare settings. These precautions are essential in protecting both healthcare workers and patients from potential infections that could be transmitted through blood and other bodily fluids. By following these guidelines, healthcare providers can reduce the risk of spreading diseases such as HIV, hepatitis B, and hepatitis C, among others. The focus of universal precautions is specifically on blood and body fluids, as they are the primary means of transmission for many infectious agents. This includes practices such as wearing gloves when there is a possibility of contact with blood, using masks and eye protection as needed, and ensuring proper disposal of sharp instruments. Other choices, while important in their contexts, do not align directly with the primary goal of universal precautions. Airborne infection spread, foodborne illness outbreaks, and skin abrasions during treatment involve different preventive measures that are specific to their transmission methods and risk factors. Understanding the specific aim of universal precautions helps in grasping their critical role in infection control within dental and medical practices.
