If the virchow triad occurs what happens?
This is the perfect situation for a DVT
What is the Virchow triad?
(E) -Endothelial damage
(V) -Venous Stasis
(A) -Altered coagulation
In the Virchow triad what does the E in EVA stand for?
Endothelial damage
In the Virchow triad what does the V in EVA stand for?
Venous Stasis
In the Virchow triad what does the A in EVA stand for?

A DVT is a common complication of these three things:
Hospitalization
Surgery
Orthopedic procedures
Why are risks increased for DVTs when a patient has an othropedic, abdominal, or thoracic surgery?
The incisions are larger
Why is smoking a risk factor to develop a DVT?
It restricts circulation
If a person exhibits on of the risk factors on the list and takes birth control what is likely to happen?
They are a ticking time bomb for a DVT
Why is a person at risk for a DVT when they have a catheter in their central vein?
Blood cells clump around the catheter and can occlude the line. This clump of cells can end up forming a clot.
Which patient is at highest risk for a venous thromboembolism?
A. A 50-year-old postoperative patient
B. A 25-year-old patient with a central venous catheter in place to treat septicemia
C. A 71-year-old otherwise healthy older adult

Why would venous gangrene be a complication of a DVT?
Blood blood due to a blockage that is created by the DVT
