What do universal precautions aim to prevent?

Universal precautions are a standard set of practices designed specifically to prevent the transmission of infections that can occur through contact with body fluids. This approach is essential in healthcare settings to protect both patients and healthcare providers. By assuming that all body fluids, including blood, saliva, and other secretions, may carry infectious agents, universal precautions require the use of personal protective equipment (PPE), proper hand hygiene, safe handling of needles, and other guidelines to minimize the risk of infection spread.

These practices are crucial for maintaining a safe environment where the likelihood of infection transmission is significantly reduced. This focus on body fluids addresses the primary concern of healthcare safety, especially in scenarios involving exposure to potentially infectious materials, making option B the most accurate answer regarding the aim of universal precautions.
