Final answer:
Universal Precautions require treating all blood and other potentially infectious materials as infectious regardless of the perceived infection risk, which is essential for preventing the transmission of pathogens like HBV in healthcare settings.
Step-by-step explanation:
When using Universal Precautions, you are required to treat blood and other potentially infectious materials as infectious regardless of the perceived infection risk. This approach is critical to preventing infection by various pathogens, including Hepatitis B Virus (HBV) and others. By treating all blood and body fluids as if they are infectious, health-care workers can significantly reduce the risk of infection transmission. Protective measures such as wearing gloves, face protection, using disposable syringes, and practicing hand hygiene with soap and water or antiseptics are essential. Moreover, post-exposure treatment with hepatitis B immunoglobulin (HBIG) and vaccination may be necessary after potential exposure. The importance of such precautions is underscored by the fact that viruses can remain infectious on surfaces for extended periods, highlighting the need for proper disinfection protocols.
