Which practice supports asepsis?

• A. Presence of microorganisms
• B. Using contaminated water
• C. Absence of disease producing organisms
• D. Sharing instruments

Answer: (C)

Asepsis means keeping the environment and all equipment free from disease-producing organisms to prevent infection, which is crucial in dialysis where access sites are highly vulnerable. The best practice that supports this goal is the absence of disease-producing organisms. When there are no harmful microorganisms present, the risk of infection is minimized during vascular access and treatment. In contrast, the presence of microorganisms, contaminated water, or sharing instruments introduces pathogens or facilitates their spread, undermining asepsis. So, maintaining an environment and processes that ensure no disease-producing organisms are present is what best supports asepsis.
