Certified Clinical Hemodialysis Technician (CCHT) Practice Exam 2025 - Free CCHT Practice Questions and Study Guide

The correct answer is that it is never permissible to reuse a dialyzer from a patient who tests positive for Hepatitis A surface antigen. This is due to the potential risk of transmitting infectious diseases. AAMI (Association for the Advancement of Medical Instrumentation) and Medicare Conditions for Coverage emphasize the importance of patient safety and infection control practices in dialysis settings.

Hepatitis A is a contagious virus that can lead to liver disease, and the presence of the Hepatitis A surface antigen indicates active infection. The guidelines are designed to protect both patients and healthcare workers from the risk of cross-contamination through the reuse of equipment that may carry infectious agents. Given the infectious nature of Hepatitis A, reusing a dialyzer without guaranteeing the absence of infectious agents would violate the strict guidelines meant to prevent the spread of diseases through the hemodialysis process.

Therefore, the consensus in clinical practice is to avoid any situations that could compromise the health of other patients or staff, leading to the conclusion that reusing a dialyzer in this scenario is never permissible.
