Which action is most effective in preventing the spread of infection in a dialysis unit?

• A. Perform hand hygiene
• B. Rely on antibiotics for prevention
• C. Only wear gloves when handling blood
• D. Disinfect surfaces weekly

Answer: (A)

Performing hand hygiene is the most effective way to prevent the spread of infection in a dialysis unit. Hands are the primary route by which germs move from one person or surface to another, so cleaning them before touching a patient, after contact with potentially contaminated items, after removing gloves, and after handling blood or body fluids breaks the chain of transmission. Alcohol-based hand rubs work well in most situations, but soap and water are necessary when hands are visibly dirty or after exposure to certain organisms.

Relying on antibiotics for prevention isn’t appropriate for stopping transmission; antibiotics don’t prevent the spread of infections and overuse can drive resistance.

Gloves are important, but they don’t replace hand hygiene. Clean hands before putting on gloves and after taking them off to avoid transferring organisms.

Disinfecting surfaces weekly isn’t sufficient in a dialysis unit, where high-touch surfaces are frequently involved in patient care. Regular cleaning and disinfection between patients help reduce cross-contamination.
