  1. What is the AAMI standard maximum allowable bacterial count in hemodialysis dialysate?

    Answer: 100 CFU/mL

    AAMI standards specify that dialysate must contain fewer than 100 CFU/mL of bacteria to be considered safe for hemodialysis treatment.

  2. Ultrapure dialysate (meeting AAMI ultrapure standards) is particularly recommended for:

    Answer: High-flux dialysis and hemodiafiltration where backfiltration could carry contaminants into the bloodstream

    High-flux membranes allow backfiltration of dialysate into the blood compartment, making ultrapure dialysate essential to prevent infusion of bacteria and endotoxins.

  3. Which practice is MOST effective at preventing cross-contamination between hemodialysis patients?

    Answer: Consistent hand hygiene between each patient contact

    Hand hygiene remains the single most effective infection control measure for preventing patient-to-patient transmission of pathogens in healthcare settings.

  4. What does the term 'pyrogenic reaction' refer to in hemodialysis?

    Answer: A febrile response caused by bacterial or endotoxin contamination of dialysate or equipment entering the bloodstream

    A pyrogenic reaction is a fever and chills response triggered when pyrogens (endotoxins or bacteria) from contaminated dialysate or equipment reach the patient's bloodstream.

  5. How frequently should dialysis station surfaces be disinfected between patients?

    Answer: After every patient treatment, before the next patient occupies the station

    All dialysis station surfaces must be disinfected between each patient to prevent transmission of bloodborne pathogens and other organisms.

  6. What is the correct response when a hemodialysis staff member sustains a needlestick injury?

    Answer: Immediately wash the wound, report the exposure, and follow the facility's bloodborne pathogen exposure control plan

    Immediate wound washing, prompt reporting, and following the exposure control plan (including source testing and post-exposure prophylaxis if indicated) are required after any needlestick.
