A nurse is reinforcing teaching with a newly licensed nurse about causative risk factors for deep vein thrombosis (DVT). Which of the following should be included in the teaching? (Select All that Apply.)
Immobility
Fracture
Atrial fibrillation
Anticoagulant therapy
Correct Answer : A,B,E
A. Immobility is a significant risk factor for DVT because it can lead to blood stasis in the veins, increasing the risk of clot formation.
B. Fractures, particularly of the lower limbs, can lead to immobilization and contribute to the development of DVT.
C. Atrial fibrillation is associated with an increased risk of clot formation, but these clots typically form in the atria of the heart, not the deep veins. While these clots can embolize to other parts of the body, atrial fibrillation itself is not a direct cause of DVT.
D. Anticoagulant therapy is typically used to prevent DVT, not as a risk factor.
E. Estrogen therapy is associated with an increased risk of clot formation, making it a risk factor for DVT.
