If a thrombus forms after a knee replacement surgery, which consequence follows from excessive fibrin production in the deep veins?

💡 Explanation

A pulmonary embolism risk elevates with a thrombus because the clotting cascade results in increased fibrin production, causing the thrombus to dislodge and travel to the lungs, obstructing pulmonary arteries. Therefore, the correct answer is pulmonary embolism risk elevation rather than reduced white blood cell extravasation, which relates to inflammation, not coagulation.
