Edelman SPI Exam /Edelman SPI Exam
Preparation/Edelman SPI Practice Exam
With Questions And Correct Answers
inertial energy loss occurs during-correct-answer--pulsatile flow (arterial
circulation)
-phasic flow (venous circulation)
-velocity changes at a stenosis
velocity increases as the vessel narrows
velocity decreases as blood flows out of stenosis into a vessel segment of normal
diameter
stenosis-correct-answer-narrowing in the lumen of a vessel
effects of a stenosis-correct-answer-change in flow direction
increased velocity as vessel narrows
turbulence downstream from the stenosis
pressure gradient across the stenosis
loss of pulsatility

Bernoulli's Principle-correct-answer-describes the relationship between velocity
and pressure in a moving fluid
pressure gradient increases when-correct-answer-flow increases or resistance
increases
flow increases when-correct-answer-pressure gradient increases or resistance
decreases
Ohms-correct-answer-electrical resistance is reported in these units
resistance vessels-correct-answer-arterioles
hydrostatic pressure (mmHg)-correct-answer-pressure related to the weight of
blood pressing on a vessel measured at a height above or below heart level
supine-correct-answer-lying on the back

hydrostatic pressure is zero
hydrostatic pressure in the supine patient with a bp of 140 mmHg-correct-answer-
at heart level
ankle, knee, midcoast, top of head = 140 mmHg
inspiration-correct-answer-diaphragm moves downward, chest cavity expands,
creating negative pressure in the chest
venous flow from head, arms and vena cava increase
abdominal compression increases
venous blood in legs decreases
expiration-correct-answer-diaphragm moves upward
increase in thoracic pressure
reduces venous return to heart
venous flow from head, arms, and vena cava decrease
Doppler Shift (Doppler frequency)-correct-answer-Difference between received
and transmitted frequencies
3|Page
, 4|Page
demodulation-correct-answer-process of extracting the low doppler frequency
from the transducers carrier frequency
doppler shift-correct-answer-doppler shift (Hz)= reflected frequency - transmitted
frequency
creation of frequency shift-correct-answer-transmitted sound waves strike moving
red blood cells
positive doppler shifts-correct-answer-- when blood cells move toward the
transducer
- reflected frequency is higher than the transmitted frequency
negative doppler shifts-correct-answer-- when blood cells move away from the
transducer
- reflected frequency is lower than the transmitted frequency
speed-correct-answer-purely magnitude
indicates the distance that a red blood cell moves in 1 sec
