What visual sign might you expect to see in a patient experiencing phlebitis?

In a patient experiencing phlebitis, redness and swelling along the vein are classic visual signs. Phlebitis is the inflammation of a vein, often resulting from irritation from the intravenous catheter or an infection. The inflammation causes the blood vessels to dilate, leading to increased blood flow in that area, which typically manifests as redness (erythema) and localized swelling (edema) along the affected vein.

This combination of symptoms helps healthcare providers quickly identify the issue, allowing for prompt assessment and treatment. Recognizing these signs is crucial as phlebitis can escalate and lead to more severe complications if not addressed.
