Which of the following best describes the purpose of universal precautions?

• A. Assume all blood and body fluids are infectious
• B. PPE is optional if gloves are worn
• C. Only visible blood requires precautions
• D. Precautions only apply in hospitals

Answer: (A)

Universal precautions work by treating all blood and certain body fluids as potentially infectious, so you consistently use protective barriers and good hygiene to prevent the spread of infections. The key idea is to protect yourself and clients by assuming a risk exists even when a substance isn’t visibly contaminated, and to apply gloves, masks or eye protection, gowns, and proper handwashing whenever exposure to blood or body fluids could occur. This safeguard targets bloodborne pathogens such as HIV, HBV, and HCV, among others, across any setting where care or service is provided.

PPE isn’t optional—relying on gloves alone isn’t enough when there’s a risk of splashes or contact with other fluids or contaminated surfaces. Precautions aren’t limited to visible blood; many fluids and contaminated surfaces can transmit infections even if blood isn’t seen. And these practices aren’t confined to hospitals—anywhere there’s potential exposure, like salons, clinics, or home care, require universal precautions to keep everyone safe.
