Dialysis Technician Practice Exam

Which method can help prevent a dialyzer reaction in patients?

1. Use polycarbonate dialyzer membrane

2. Use cellulose acetate dialyzer membrane

3. Administer antihistamines

4. Decrease dialysis time

The correct answer is: Use cellulose acetate dialyzer membrane

Using a cellulose acetate dialyzer membrane can help prevent a dialyzer reaction in patients because this type of membrane is known for its biocompatibility. Cellulose acetate is less likely to induce an immune response, making it a safer option for patients who may have sensitivities to certain materials. The membrane's chemical structure does not activate complement or leukocyte activation as aggressively as some alternative materials, reducing the chances of reactions during dialysis. While there are other methods to manage potential reactions, such as administering antihistamines or using different types of membranes, cellulose acetate specifically provides a proactive approach by utilizing materials that are less reactive with the body’s immune system. This characteristic is particularly valuable in preventing an immune response that can lead to complications during treatment.
