Answer 29

B) Transverse view proximal to distal

Question 30

While performing venous compressions you notice the artery is compressing but not the vein, what does that mean?

Answer 30

There is a DVT

Question 31

T/F. Compression should only be performed every 6 inches down the leg.

Question 34

Explain why a DVT poses a greater risk for pulmonary embolism compared to a superficial vein thrombus.

Answer 34

"A deep vein thrombosis will typically be larger in size, therefore posing a greater risk to the larger vessels of the lung"
