Patient was educated on pathophysiology of deep vein thrombosis as follows:

1. 1. Deep vein thrombosis (DVT) is a condition, when blood clots form in the deep veins of the body, secondary to slow blood flow and changes in the thickness of blood.
   2. Bilateral lower extremities and lower parts of the body below the heart level are more prone for formation of these clots, as venous blood flow in these body parts is sluggish, in comparison to the rest of the body.
   3. The venous blood in these body parts, while returning to the heart, must travel against gravity towards the heart. This slows down the blood flow, thus increasing the risk for clot formation.
   4. Blood flow in the veins of lower extremities could be slow secondary to prolonged bedbound status, sedentary lifestyle, or damaged veins unable to move the blood up along the limb.
   5. Also, increased thickness of blood due to various factors, such as, inappropriate blood thinner dose, can result in clot formation and DVT.
