ARRT CI UPDATED EXAMINERS SET
QUESTIONS AND ANSWERS SURE A+
✔✔What term describes the size of a needle lumen?
A. cannula thickness
B. coil size
C. core size
D. gauge - ✔✔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.

the Seldinger technique?
A. avoidance of major nerves
B. reduction of blood clotting
C. to attain good blood return
D. to avoid vascular shock - ✔✔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 is zero time?
A. the time between exposure switch contact and initiation of exposure
B. the time necessary for the electronics in an automatic film changer to respond.

✔✔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 - ✔✔Answer B
