What action should a technician take if a patient reports itching during dialysis?

When a patient reports itching during dialysis, it is crucial for the technician to assess for allergic reactions because itching can be a sign of an allergic response to medications, dialysate, or other materials used in the dialysis process. By evaluating for signs of an allergic reaction, such as rash, swelling, or changes in vital signs, the technician can determine if the itching is part of a larger issue that may require immediate medical attention.

This assessment helps ensure the safety and well-being of the patient, allowing for appropriate interventions to be taken based on the findings. Understanding the root cause of the itching is important for effective management and can lead to adjustments in treatment or medication if necessary.

While increasing the blood flow rate, adjusting dialysate bicarbonate, or administering antihistamines might be considered in different contexts or patient conditions, they do not directly address the immediate need to investigate a possible allergic reaction in this scenario.
