What is the correct term used to describe an intravenous injection of a concentrated
volume of contrast media?
a. bolus
b. infusion
c. extravasation
d. luminal - <<ANSWER>>a. bolus
Which of the following methods utilizes a detector that captures x-ray energy and
converts it into an electronic signal?
a. indirect capture
b. CCD
c. cassette based radiography
d. direct capture - <<ANSWER>>d. direct capture
The energy of a characteristic x-ray photon created when an L shell electron fills a K
shell vacancy in a tungsten atom will have which of the following energies?
a. 69.5 keV
b. 57.5 keV
c. 91.5 keV
d. 12 keV - <<ANSWER>>b. 57.5 keV
The energy of characteristic photons is determined by the difference in binding energies
between the two electron shells involved in the process, which in this question are K
and L shells. 69.5 (K shell) minus 12 (L shell) equals 57.5.
Identify the position that will place the positive contrast agent in the body of the stomach
and pyloris during a double contrast upper GI exam?
a. recumbent LPO
b. supine

,which position/projection will best demonstrate the broad aspect of the frontal air sinus?
- <<ANSWER>>PA
Which position will best demonstrate the right axillary portion of the ribs? -
<<ANSWER>>RPO
which of the following interactions occurs most often with x-ray energies over 100 keV?
a. coherent(classical) scattering
b. compton
c. photoelectric absorption
d. pair production - <<ANSWER>>b. compton
(the higher the energy, the more apt the xray will be scattered)
a body at rest or in uniform motion remains in the same state unless a force is applied
describes what?
a. A=F/m
b. for every action there is a reaction
c. Newton's first law of motion
d. Coulomb's Law - <<ANSWER>>c. Newton's first law of motion
what is the definition of power?
a. the rate at which work is done
b. the stored energy of an object
c. a body at rest
d. the force of a moving object - <<ANSWER>>a. the rate at which work is done
what is the definition of energy?
a. moving or stationary objects
b. mass times acceleration
c. the rate at which work is done
d. the ability to do work - <<ANSWER>>d. the ability to do work
which of the following describes an electron?
a. no mass and no charge
b. no mass and negative charge
c. mass and no charge
d. mass and negative charge - <<ANSWER>>d. mass and negative charge
what is the formula for converting Fahrenheit to Celsius? - <<ANSWER>>5/9 (F-32)
which of the following describes an atom that has lost one or more of its electrons?
a. ion
b. isotope
c. nuclide
d. unstable - <<ANSWER>>a. ion
,at 70 kVp, 200 mA, and 0.2 seconds, what is the mR/mAs if the rate meter reading is
100 mR?
a. 1.0 mR/mAs
b. 2.5 mR/mAs
c. 4.0 mR/mAs
d. 5.5 mR/mAs - <<ANSWER>>b. 2.5 mR/mAs
(200 mA x 0.2 seconds = 40 mAs. 100 mR divided by 40 mAs = 2.5 mR/mAs)
