 Many times in nursing school, we worry about or we hear about deep vein thrombosis and there are usually a lot of core measures set in place by facilities to prevent deep vein thrombosis. And risk factors for developing blood clots in the legs are prolonged periods of sitting or immobility. So that's anybody who's hospitalized and not as mobile as they usually are. Even prolonged periods of sitting in an airplane or in a car can lead to deep vein thrombosis. Patients with heart failure are at higher risk as well as women over the age of 35, especially if they take birth control pills. Also patients who are pregnant or in the postpartum periods because of the increase in blood volume that is caused by pregnancy and the fetus. And then also patients who have a history of IV drug abuse because of the insertion of the needle that's not usually done in a very clean or sterile manner, there can be some clotting that happens there. And the other reason is that there can be some trauma that occurs to the veins and the platelets aggregate forming a thrombus causing venous thrombosis.
