Answer:
Bedrest
Step-by-step explanation:
A deep vein thrombosis (DVT) is a condition in which a blood clot (thrombus) forms within the vasculature of the lower extremities, usually as a result of other conditions (e.g. clotting disorders) or commonly when a patient is not moving their extremities over a substantial period of time, as is the case when a patient is on bedrest. These occur because the muscles do not contract when the patient is not moving, which stagnates blood flow. These blood clots are dangerous because they decrease the diameter of the lumen of the blood vessels, partially restricting blood flow; they are particularly dangerous when they the become dislodged from their origin point and can travel to smaller vessels where they can then occlude blood flow almost completely -- in this case, the thrombus is called an embolus.
The way to prevent the development of DVTs is to:
- remain hydrated which can maintain blood volume and improve circulation, thus decreasing platelet aggregation;
- encourage the patient to ambulate as early as possible to stimulate perfusion to these lower extremities and contract these muscles which improves circulation;
- and wear compression stockings, because this type of clothing stops the pooling of blood in the lower extremities and forces it upward towards the heart thereby decreasing the risk of developing a clot.
Of the given choices, risk factors of developing a DVT includes bed rest, the first option.
