Which of the following is a common symptom of a dialyzer reaction?

  1. Headache

  2. Nausea

  3. Back Pain

  4. Fever

The correct answer is: Back Pain

A dialyzer reaction can produce various symptoms, with back pain being a notable one. This type of pain may occur due to irritation or issues related to the filtration process within the dialyzer, which can trigger discomfort or pain in the back. While other symptoms can also be present during a reaction, back pain specifically is often associated with mechanical problems or complications in the dialysis procedure. For instance, clotting of the dialyzer can lead to back pain due to hemodynamic changes or pressure gradients that affect the patient's comfort and overall response to the treatment. Headaches, nausea, and fever can also be symptoms experienced during a reaction to dialysis but are more commonly linked to other underlying issues or complications. Thus, back pain clearly characterizes a common symptom directly associated with the use of a dialyzer during treatment.
