Universal precautions mandate treating all blood and bodily fluids as if they are contaminated to minimize the risk of infection. This creates a consistent, safety-forward approach so you always use gloves and other PPE, perform proper hand hygiene, and handle and dispose of sharps and spills safely, regardless of the situation. The idea is not to guess who might be infectious but to assume potential risk and act accordingly, which reduces transmission of infections like HIV and hepatitis B and C. The other statements would weaken safety: ignoring contaminated materials increases exposure, applying precautions only in some situations misses the universal aspect, and making them optional would undermine established safety standards.
