Which of the following is a sign of disinfectant infusion?

Pain at the venous needle site is indeed a sign of disinfectant infusion. This discomfort often arises when concentrated disinfectants, like chlorhexidine or other antiseptics, inadvertently enter the bloodstream during hemodialysis. The infusion of irritants can result in localized pain and soreness at the site where the venous needle is placed, reflecting tissue irritation or inflammation due to chemical exposure.

Recognizing this symptom early is crucial for healthcare providers, as it allows them to address the situation promptly, ensuring patient safety and comfort. Monitoring the patient for any signs of distress or discomfort during treatment can facilitate timely intervention and potentially prevent complications related to disinfectant exposure.
