Which statement about universal precautions is correct?

Universal precautions are essential guidelines designed to prevent the transmission of bloodborne pathogens and are meant to protect workers who may come into contact with blood and other potentially infectious materials. The correct statement regarding universal precautions is that they apply to all blood and body fluids. This means that regardless of whether an individual is known to be infected or not, all blood and body fluids should be treated as if they are potentially infectious. This approach is vital in maintaining safety and reducing the risk of exposure to diseases, such as HIV and Hepatitis B, across various settings, not limited to healthcare. It promotes a proactive and consistent standard of practice for everyone, ensuring that proper protective measures are used at all times.

The other statements misinterpret the principle of universal precautions: they are not limited to known infected individuals, nor are they applicable solely within healthcare environments; they are relevant in any situation where exposure to blood or body fluids might occur. Additionally, they are not optional and should always be followed to ensure maximum safety and health protection.
