What term describes the resistance of contrast material due to the
attraction of molecules to each other?
A. persistence
B. toxicity
C. miscibility
D. viscosity - Correct Answer - Answer D
What term describes a solution with an ionic concentration higher than
normal body fluids?
A. isotonic
B. hyperostatic
C. hyperosmolar
D. osmotic - Correct Answer - Answer: C
Hyperosmolar solutions have an ionic concentration higher than normal
body fluids.
How long is the injection time for 30ml of contrast media delivered at
3.7ml/sec?
A. 0.1sec
pg. 1
,2|Page
B. 4.5sec
C. 8.1sec
D. 111sec - Correct Answer - Answer: C
Injection time is calculated as volume/time, so 30/3.7=8.1 seconds.
What is the primary reason that guide wires must have a flexible tip?
A. to permit bending and avoid damage to vascular walls
B. to permit whip lash to occur
C. to avoid unraveling
D. to avoid clotting - Correct Answer - Answer: A
The primary reason guide wires must have a flexible tip is to permit
bending and avoid vascular wall damage.
What term describes the thin wire along which a catheter will be
threaded when it is inserted into a vessel?
A. French catheter
B. Seldinger needle
C. guide wire
D. J wire - Correct Answer - Answer C
Which of the following increases the flow rate of contrast media?
A. decreased pressure
B. decreased viscosity
C. increased catheter length
pg. 2
,3|Page
D. decreased catheter diameter - Correct Answer - Answer: B
Decreased viscosity of contrast material will increase the flow rate.
Decreased pressure, increased catheter length, and decreased catheter
diameter will all decrease the flow rate.
What term describes the size of a needle lumen?
A. cannula thickness
B. coil size
C. core size
D. gauge - Correct Answer - Answer D
The needle lumen is identified by a gauge number. The higher the gauge
number, the smaller the inner diameter of the lumen and vice versa.
What is the purpose of the slow withdrawal of the needle after arterial
penetration in the Seldinger technique?
A. avoidance of major nerves
B. reduction of blood clotting
C. to attain good blood return
D. to avoid vascular shock - Correct Answer - Answer C
The purpose of the slow withdrawal of the needle after arterial
penetration in the Seldinger technique is to attain good blood return.
What technique is used to introduce the catheter during a percutaneous
transluminal angioplasty?
A. cut-down method
pg. 3
, 4|Page
B. Thompson technique
C. Seldinger technique
D. Addison technique - Correct Answer - Answer C
What legal doctrine, now in decline, holds that the employer is
responsible for the acts of the radiographer?
A. assault and battery
B. res ipsa loquitor
C. repondeat superior
D. habeas corpus - Correct Answer - Answer C
What can be determined when dividing the volume of contrast material
delivered by the rate of injection?
A. coefficient of contrast media viscosity
B. length of time of injection
C. arterial pressure per cc
D. length of catheter in centimeters - Correct Answer - Answer B
What is the most common Seldinger technique approach?
A. femoral artery
B. common iliac artery
C. brachial artery
D. femoral vein - Correct Answer - Answer A
