Hospital Medicine Point of Care Ultrasonography

1. How do you diagnose a deep vein thrombosis on point-of-care ultrasound?

Visualization of the thrombus in the vein
Lack of vein compressibility
Lack of blood flow on color doppler
A & B
A & C
All of the above

2. Which of the following statements about arteries and veins is correct?

Veins usually have a thicker muscular wall.
Arteries are more oval in shape than veins.
Veins contain valves that may be visible on ultrasound.
Veins are more difficult to compress than arteries.

3. When performing a POCUS DVT study, what is the most proximal branch point of the common femoral vein?

Popliteal vein
Lateral perforator vein
Greater saphenous vein
Greater saphenous vein

4. How can you tell the difference between the superficial femoral vein level from the popliteal vein level on ultrasound imaging?

How can you tell the difference between the superficial femoral vein level from the popliteal vein level on ultrasound imaging?
The popliteal vein is superficial to the popliteal artery.
The popliteal vein is deep to the popliteal artery.
Both levels look the same on ultrasound imaging.

5. Which of the following statements about POCUS DVT imaging acquisition is false?

The linear probe or the abdominal probe can be used.
We use the procedural orientation when acquiring DVT images.
Compression is applied at each level.
The patient can be supine or standing when scanning for the popliteal vein.

6. How much compression is adequate when performing a POCUS DVT study?

When the nearby artery is completely collapsed.
When both the vein and artery are completely collapsed.
When the nearby artery is slightly deformed from the compression.
Compression is not needed to perform a DVT study.

7. Which DVT study protocol should be used when performing a bedside POCUS exam?

Two zone compression ultrasound
Extended compression ultrasound
Complete compression ultrasound
A or B
Any of the above
