Answer 25

Right sided heart failure

Question 26

If you find an IVC tumor what organ do you check next

Answer 26

Kidneys

Answer 28

c) left innominate vein obstruction -A continuous waveform means there is a proximal venous obstruction. Since the waveform is only on 1 side, the obstruction is isolated just proximal to that side
