DEEP VEIN THROMBOSIS (DVT) EXAM
QUESTIONS AND ANSWERS
What is a DVT? - Correct Answers -A blood clot in a large vein, usually the leg or pelvis
If the DVT becomes mobile where can it end up and what is it caused? - Correct
Answers --Pulmonary embolism (PE)
-Venous thromboembolism (VTE)
What are some causes/ risk factors of DVTs? - Correct Answers --Increased age
-Active cancer with or without chemotherapy
-Varicose veins
-Prior venous thrombosis
-Pregnancy
-Postpartum period
-Oral contraceptive
-Hormone therapy
-Anything that causes a client to be immobile
-Central vein catheterization
-Transvenous pacemaker insertion
How is a DVT formed? - Correct Answers -Virchow's Triad
-Decreased flow rate of the blood or (stasis) of blood flow
-Damage tot he blood vessel wall; (endothelial injury)
-Increased tendency of the blood to clot (hypercaogulation)
What provides the ideal setting for clot formation? - Correct Answers -One-way valves
prevent the back flow of blood between the contractions. Blood is squeezed up the leg
against gravity, and the valves prevent it from flowing back to the feet. When the
circulation of the blood slows down because of illness, injury, or inactivity, blood can
accumulate or "pool," which provides an ideal setting for clot formation
What are some actions you need to take for a client who has a DVT? - Correct Answers
--Early ambulation
-Leg elevation: prevent swelling
-Compression stockings
-Avoid sequential compression devices
(SCDs): May result in an embolism
-Encourage adequate fluid intake
-Administer medications as ordered: Anticoagulation, thrombolytic agent
