Thrombophlebitis involves:

Thrombophlebitis involves:

• A. Inflammation of Arteries
• B. Abnormal Heart Sounds
• C. Blood Blocks Flow of a Vein
• D. Varicose Veins

Answer: (C)

Thrombophlebitis is when a blood clot forms inside a vein and triggers inflammation of the vein wall, often with reduced blood flow through that vein. The essential point is that the clot blocks venous flow, so the description that blood blocks flow of a vein best captures what’s happening. Inflammation of an artery would be arteritis, not thrombophlebitis. Abnormal heart sounds point to heart conditions rather than venous inflammation. Varicose veins are dilated, twisted veins from valve failure and venous insufficiency; they describe a different venous issue, not the clot-related obstruction and inflammation at the heart of thrombophlebitis.
