◉ How long is the injection time for 30ml of contrast media
delivered at 3.7ml/sec?
A. 0.1sec
B. 4.5sec
C. 8.1sec
D. 111sec. 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. 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. Answer: Answer C
◉ Which of the following increases the flow rate of contrast media?
A. decreased pressure
B. decreased viscosity
C. increased catheter length
D. decreased catheter diameter. 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
