The nursing instructor is talking with a group of medical–surgical students about deep vein thrombosis (DVT). A student asks what factors contribute to the formation of a DVT. What would be the instructor's best response?
A) "There is a genetic link in the formation of deep vein thrombi."
B) "Hypervolemia is often present in patients who go on to develop deep vein thrombi."
C) "No known factors contribute to the formation of deep vein thrombi; they just occur."
D) "Dehydration is a contributory factor to the formation of deep vein thrombi."
Ans: D
Feedback:
The stress response that is initiated by surgery inhibits the fibrinolytic system, resulting in blood hypercoagulability. Dehydration, low cardiac output, blood pooling in the extremities, and bedrest add to the risk of thrombosis formation. Hypervolemia is not a risk factor and there are no known genetic factors.
