Which of the following is NOT a potential cause of provoked DVT?

Prolonged immobility
Recent surgery
Trauma
Uncontrolled hypertension

The correct answer is: Uncontrolled hypertension

Provoked deep vein thrombosis (DVT) occurs in response to certain identifiable risk factors or causes. Prolonged immobility, recent surgery, and trauma are all well-established triggers that can lead to DVT. Prolonged immobility can result in reduced blood flow and stasis, which increases the risk of clot formation in the veins, especially in the lower extremities. Recent surgery, particularly orthopedic or pelvic surgeries, can also provoke DVT due to tissue damage and the body's inflammatory response, which may contribute to clotting. Trauma can similarly lead to DVT through injury to blood vessels or prolonged immobilization after the injury. Uncontrolled hypertension, however, is not a direct provocation for DVT. While it may contribute to overall cardiovascular risk or complications related to clotting predispositions, it does not serve as an immediate causative factor for the formation of blood clots in the same way the other options do. Therefore, it is correctly identified as not a potential cause of provoked DVT.
