Which statement about dialysis infection control is correct?

• A. All surfaces must be disinfected with 1:100 bleach solution until glistening wet and air-dry
• B. Disinfection is optional for large spills
• C. PPE is not required if exposure does not involve blood
• D. Hep B requires no isolation measures

Answer: (A)

Infection control in dialysis hinges on using an effective disinfectant at the right strength and giving it time to work. A key concept is that surfaces contaminated with blood or body fluids must be disinfected thoroughly, and you know you’ve done it correctly when the surface remains visibly wet for the required contact time. The statement about using a bleach solution at a specific dilution and continuing the clean until the surface is glistening wet and then air-drying emphasizes both choosing an appropriate disinfectant strength and allowing proper contact time. This wetness ensures pathogens are in contact with the disinfectant long enough to be inactivated.

In dialysis settings, disinfection isn’t optional for spills or routine surfaces, and PPE is required whenever there is exposure to blood or body fluids. Hepatitis B protection relies on standard precautions and facility policies about transmission-based precautions when indicated, not on ignoring precautions. So the emphasis on a proper bleach concentration and ensuring surfaces stay wet long enough to air-dry captures the correct approach to reliably reduce infection risk.
