Universal Precautions require treating all human blood as if infectious. Which option best reflects this?

• A. Isolate patients with known infection
• B. Use sterile equipment for invasive tasks
• C. Rely on standard hygiene alone
• D. Treat all human blood as if infectious

Answer: (D)

Universal Precautions mean you treat any blood or potentially infectious material as if it were infectious, and apply protective measures consistently in every encounter. The statement that best reflects this is the one that says to treat all human blood as if infectious. This approach drives the use of gloves, eye protection, masks as needed, proper hand hygiene, safe needle and sharps handling, cleaning and disinfection of surfaces, and correct waste disposal—applied to all patients and procedures, not just those known to be infected.

The other ideas miss the universal mindset: isolating patients only when infection is known targets specific cases rather than all encounters; relying on hygiene alone is not sufficient because protective equipment and safe practices expand beyond basic cleanliness; relying on sterile equipment for invasive tasks relates to aseptic technique, which is important but not the same universal-precautions framework.
