While evaluating the liver vasculature with color Doppler, you are
unable to obtain signals from the deeper vessels. What should
you do to enhance your ability to demonstrate deep flow?
A. Decrease the packet size
B. Increase the scan line density
C. Increase the wall filter
D. Increase the pulse repetition frequency
E. Decrease the ultrasound frequency -ANSWERS-Decrease the
ultrasound frequency
Loss of fluid energy through inertia
A. Is greatest during steady flow through a rigid tube of constant
caliber
B. Is best described by Poiseuille's law
C. Is greatest in a tortuous vessel with multiple obstructions
, Page |2
D. Accounts for less energy loss than viscous losses
E. Is greatest with high flow speeds in a large tube -ANSWERS-Is
greatest in a tortuous vessel with multiple obstructions
Which of the following statements about turbulent flow is NOT
true?
A. It can be predicted by the Reynolds number.
B. It is responsible for murmurs, bruits, and thrills.
C. It causes an increase in pressure downstream.
D. It occurs where there are abrupt variations in vessel diameter.
E. It is affected by velocity. -ANSWERS-It causes a pressure
downstream
Which of the following statements most correctly describes the
occurrence of diastolic flow reversal in the arterial system?
A. It is always an abnormal finding.
B. It is seen in and proximal to high-resistance vessels.
C. It is most commonly observed in vessels that supply low-
resistance beds.
, Page |3
D. It can be enhanced by body heating.
E. It is found in the internal carotid artery. -ANSWERS-It is seen
in and proximal to to high resistance vessels
You measured an area reduction of 90% in the artery shown in
this image. This is equal to a diameter reduction of
A. 25%
B. 30%
C. 50%
D. 75%
E. 90% -ANSWERS-75 %
The Doppler waveform you have obtained from a collateral
channel shows high resistance compared to the contralateral
normal artery. The increased resistance may be attributed to
A. Decreased tube diameter
B. Increased vessel length
C. Decreased resistance in the vascular bed
D. All of the above
, Page |4
E. A and B -ANSWERS-Decreases tube diameter and increased
vessel length
After a short walking exercise, the venous pressure at the ankle of
a standing normal subject
A. Is greater than the standing ankle pressure at rest
B. Is lower than the standing ankle pressure at rest
C. Is the same as standing ankle pressure at rest
D. Is not affected by chronic venous insufficiency
E. Is not affected by deep venous thrombosis -ANSWERS-Is
lower than the standing ankle pressure at rest
Your patient has edema involving the right lower extremity. This
may be caused by
A. Increased intravenous pressure
B. Decreased venous hypertension
C. Decreased venous hypervolemia
D. Increased venous hypovolemia
