B. 50 to 60 percent increase
C. 10 to 20 percent decrease
D. 50 to 60 percent decrease - ✔✔The addition of side holes in a catheter will increase
the flow rate to 10 to 20 percent.
✔✔What is the area relationship indicated by the power factor of an automated injector?
1. power cylinder
2. catheter
3. syringe
A. 1 and 2 only
B. 1 and 3 only
C. 2 and 3 only
D. 1, 2, and 3 - ✔✔The power factor of an automatic power injector indicates the area
relationship of the power cylinder to the syringe
✔✔How long is the injection time for 12ml of contrast media delivered at 2.5 ml/sec?
A. 0.2 sec
B. 2.5 sec
C. 4.8 sec

B. 1 and 3 only
C. 2 and 3 only
D. 1, 2, and 3 - ✔✔Answer: A
✔✔Which of the following is not a proper technique of custom shaping of a catheter?
A. the cut tip should be smooth
B. shape the tip in hot water
C. fix the tip in cold water
D. punch side hole opposite one another - ✔✔Answer: D
, ✔✔Which of the following are inversely proportional to contrast delivery rate?
1. catheter length
2. catheter diameter
3. more side holes
A. 1 only
B. 2 only
C. 3 only
D. 1, 2, and 3 - ✔✔Answer: A
✔✔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: 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: 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 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: 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
