Certified Hemodialysis Technician Practice Exam 2025 – All-in-One Guide to Exam Success

Monitoring signs of infection and blood flow in patients with arteriovenous (AV) fistulas is crucial for several reasons. AV fistulas are created for effective hemodialysis access, allowing blood to flow from the body to the dialysis machine. Regular observation for signs of infection is essential since any infection at the site can lead to serious complications, including sepsis or failure of the fistula itself.

In addition to infection, monitoring blood flow through the AV fistula is vital to ensure it is functioning properly. Reduced blood flow can indicate problems like thrombosis or stenosis, which could hinder the effectiveness of dialysis treatment. A properly functioning fistula is essential for achieving adequate dialysis sessions and avoiding potential health complications.

While tracking temperature and weight, sodium levels, and urine output are important components of patient care, they do not specifically focus on the status of the AV fistula itself. Thus, the emphasis on monitoring signs of infection and blood flow makes it the most relevant answer in ensuring the safety and efficacy of hemodialysis treatment.
