Universal precautions means that you should assume that all blood is infectious in nature, unless you can prove otherwise.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Universal precautions mean you treat all human blood and certain body fluids as if they are infectious, regardless of how safe you think the source might be. This approach is used because you can’t know for sure who is carrying bloodborne pathogens like hepatitis B or C or HIV just by looking at someone, so you protect yourself by applying the same safeguards every time. In practice, this means using gloves, eye or face protection, and barriers; promptly cleaning up any spills; and disposing of contaminated materials properly. The idea is to maintain precautions consistently rather than waiting for proof of infection, which is why the statement is correct. Other options would imply variability in risk, which universal precautions explicitly avoid.
