URR physiologic Exams Questions With
Correct Answers.
Describe an Air Plethysmography exam that is positive for venous insufficiency: -
answer✔✔After the legs are elevated, and then the patient stands, the venous filling index will
be increased
A APG exam is performed by placing a large cuff around the calf. The leg is elevated until the
plethysmography tracing plateaus indicating the veins have emptied. The patient will then
quickly stand up to assess the right of venous refill under the cuff. A fast refill time occurs with
_______________ . A VRT greater than _____ seconds is considered normal -
answer✔✔Valvular insufficiency; 20
The venous refill index is measured in: - answer✔✔mL/sec
VFI of <2 mL/sec is ________ - answer✔✔Normal
VFI of >7 mL/sec indicates ______________ - answer✔✔Severe insufficiency
Most commonly the posterior tibial and dorsalis pedis arteries, are used to obtain the pressure of
the ankle. What is the correct calculation of the ankle brachial index? - answer✔✔Highest ankle
pressure on each leg divided by the highest brachial pressure
A double peaked waveform obtained during PPG evaluation of the digits of the left hand is
indicative of - answer✔✔Raynaud syndrome
Normal ABI's with abnormal digit tracings indicates obstruction of the digital arteries by
___________ - answer✔✔Embolisms
What is a major limitation of a lower extremity segmental pressure exam when compared to a
Doppler evaluation? - answer✔✔The segmental pressure technic cannot differentiate external
iliac from common femoral stenosis/occlusion
______________ can demonstrate the level of the problem in the extremity, but cannot
determine the extent stenosis or obstruction that is present - answer✔✔Segmental pressures
Upon cessation of exercise, the ankle pressures in a normal patient will: - answer✔✔decrease to
normal levels in less than 5 minutes
A patient presents for an exercise arterial exam after an abnormal resting exam. The report from
the resting exam describes elevated velocity is that indicate a stenosis of greater than 50% in the
distal femoral artery on the left leg, that biphasic waveforms in the PTA and DPA and an ABI of
0.96. There is no change in the waveforms or decrease in ankle pressures in the left leg with
exercise. What could explain these findings? - answer✔✔Extensive collateral formation
(exercise induces peripheral vasodilatation. If collateral flow is present, it will compensate for
the expected drop in flow and pressure from a diseased vessel)
Increased peripheral resistance will lead to _____________ amplitude in PVR tracings -
answer✔✔increased
A patient presents with a script for an upper extremity PPG exam to rule out Raynaud syndrome.
How will you perform the exam? - answer✔✔Place PPG sensors on the tips of the fingers before
and after cold sensitivity test
____________ pressures should be obtained with the patient sitting upright, hand placed on a
positioning, wedge or pillow - answer✔✔Finger
A normal lower extremity arterial response to reactive hyperemia is - answer✔✔<35% drop in
ankle pressures that return to normal within 1 minute
This method is preferred to evaluate suspected popliteal entrapment - answer✔✔PPG tracing of
the digits at rest and during dorsiflexion
Lower extremity arterial segmental pressure exam results in a post exercise basal pressure
recovery time of greater than six minutes which suggests - answer✔✔Multilevel stenosis
Lower extremity arterial, segmental pressure exam resulting in post exercise basal pressure
recovery time of 2 to 6 minutes suggest ___________ - answer✔✔Single level stenosis
when the allen test is performed with significant abnormal findings, what happens to the digit
PPG tracings with radial artery compression? - answer✔✔amplitude significantly decreases
The Adson maneuver is helpful in the diagnosis of what vascular disorder? - answer✔✔Thoracic
outlet syndrome
The ________________ is a patient position used to evaluate flow changes with thoracic outlet
syndrome. Palpate the radial pulse on the affected side with the elbow fully extended. Have the
patient rotate their head to the side being tested and extend the neck. Then abduct, extend, and
laterally rotate the shoulder. From this position, have the patient take a deep breath and hold,
assess the pulse response. A positive test is a decrease in pulse vigor from the starting position to
the final position. - answer✔✔Adson maneuver
