When assessing the IV site, which of the following findings would suggest phlebitis?

The presence of pain and soreness at the IV site is a key indicator of phlebitis. Phlebitis is the inflammation of a vein, and it is commonly associated with discomfort in the affected area. Patients may report pain that is localized along the vein where the IV catheter is placed. This symptom often arises due to the irritation of the vein wall caused by multiple factors, including catheter movement, the type of solution being infused, or the presence of a pre-existing infection.

While other findings can indicate various complications or issues, the specific symptom of pain or soreness directly correlates with phlebitis. It's important to recognize that phlebitis often manifests with tenderness in addition to other signs, but pain is a primary symptom that prompts further investigation and management of the IV site.
