All dialysis surfaces must be disinfected with which solution and process?

All dialysis surfaces must be disinfected with which solution and process?

• A. 1:100 bleach solution, wet, air dry
• B. 1:50 bleach solution, wet, air dry
• C. 1:10 bleach solution, dry, air dry
• D. 1:1000 bleach solution, wet, air dry

Answer: (A)

Disinfection depends on using the right chemical concentration and letting it act long enough. A 1:100 bleach solution provides an effective level of sodium hypochlorite for dialysis-area surfaces without being unnecessarily harsh. Concentrations that are stronger aren’t needed for routine disinfection and can cause more wear or irritation, while a weaker solution won’t reliably kill pathogens. The key is to keep the surfaces visibly wet with the solution for the required dwell time so the disinfectant can work, then allow the area to air dry. Merely wiping and letting it dry without that wet contact time won’t achieve disinfection.
