Vascular Module Step 9, Part 2

1. Which of the following is true about venous thrombosis?*
- A. The use of ultrasound has decreased the incidence of subsequent thrombosis
- B. Ultrasounds help identify cases of pre-existing thrombosis
- C. Ultrasounds help identify cases of pre-existing thrombosis
- D. Both B and C
2. Gold standard to confirm venous patency is:*
- Ability of vein to collapse with probe pressure (walls coming together)
- Ability of vein to expand when performing Valsalva maneuver
- Fact that no thrombotic material can be seen in vessel
- Ability of vein to vary with size due to respiration
3. In a patient with a high clinical suspicion for DVT, a negative scan on your exam should:*
- Should be repeated twice a day for 72 hours
- Should be repeated daily for 48 hours
- Greatly reduces likelihood and full duplex does not need to be ordered even if the suspicion is high
- Strongly suggest that be confirmed with a full duplex study performed by an expert
4. A focused compression ultrasound technique involves compression of which veins?*
- Iliac and popliteal
- Superficial femoral and popliteal
- Common femoral and deep femoral
- Common femoral down to its bifurcation and then popliteal
5. What structure is commonly confused with venous thrombosis?*
- Femoral nerve
- Inguinal hernia
- Lymphatic channel
- Lymph node
