Before patient use, the reprocessed dialyzer is rinsed to remove which item?

• A. Blood residues
• B. Dialysate
• C. Dust
• D. Residual germicide

Answer: (D)

Rinsing before patient use targets removing any residual germicide left from the disinfection step. After reprocessing, a chemical disinfectant may still be present, and flushing the dialyzer with clean rinse fluid prevents exposure to it and potential adverse reactions during the upcoming dialysis session. Blood residues and dialysate have already been addressed earlier in the cleaning and preparation process, and dust isn’t the issue in this context. The key substance being cleared by the rinse is the residual germicide.
