Reuse in dialysis practice refers to cleaning and disinfecting of:

• A. Dialyzers
• B. Bloodlines
• C. Dialysis machines
• D. Water treatment system

Answer: (A)

Reuse in dialysis practice means reprocessing a dialyzer between treatments so it can be used more than once. The dialyzer contains a specialized membrane that performs diffusion and removal of waste, but after a session it can carry blood, proteins, and potential microbes. Cleaning removes these residues, and disinfection kills any microorganisms, helping restore the dialyzer’s function and make it safe for another use. Before reusing, the dialyzer is tested to confirm adequate clearance and that there are no leaks or membrane damage.

Bloodlines are designed for single use to prevent cross-contamination and infection risk. The dialysis machine and the water treatment system are cleaned and maintained regularly, but the term reuse refers specifically to reprocessing dialyzers for multiple uses, not the machines or water system.
