Which term describes inflammation of a vein with clot formation?

• A. Thrombophlebitis
• B. Thrombus
• C. Spontaneous pneumothorax
• D. Tinnitus

Answer: (A)

Thrombophlebitis describes inflammation of a vein accompanied by clot formation. The term combines thrombus (clot) with phlebitis (vein inflammation), capturing both parts of the process. A thrombus alone is only the clot, not the inflammatory vein condition. Spontaneous pneumothorax and tinnitus are unrelated—pneumothorax is air in the pleural space causing lung collapse, and tinnitus is ringing in the ears. Thrombophlebitis may present with warmth, redness, tenderness along a superficial vein, and sometimes swelling.
