Question

Thrombosis refers to clotting within the vascular access. There is a risk of thrombosis when _______.

1) The blood flow is slow or stagnant.
2) There is damage to the blood vessel walls.
3) There is an increase in platelet count.
4) There is a deficiency of clotting factors.

Answer 1

Thrombosis, the formation of blood clots within the vascular system, can occur with slow or stagnant blood flow, vessel wall damage, or an increased platelet count, but not typically with a deficiency of clotting factors.

Step-by-step explanation:

Thrombosis refers to the formation of a blood clot, known as a thrombus, within the vascular system. This can occur when the blood flow is slow or stagnant, as well as when there is damage to the blood vessel walls. Another risk factor for thrombosis is an increase in platelet count, as seen in conditions such as thrombocytosis. Thrombosis can be induced by multiple factors, including venous stasis in situations such as prolonged immobility during long flights, or this may be a result of genetic predispositions or acquired conditions, like polycythemia vera, sickle cell disease, or obesity. On the other hand, a deficiency of clotting factors would typically hinder clot formation rather than promote it, making it less likely to contribute to thrombosis.
