Which bony landmark is commonly used for central ray location an an
anteroposterior (AP) chest projection? - CORRECT ANSWERS Jugular notch
A radiographer prepares to do an excretory urogram on a patient who has a history
of asthma. At this institution, policies are in place to select the type of contrast used
based on the needs of the patient. Which type of contrast should be used in this
situation? - CORRECT ANSWERS Iodinated, nonionic
In conventional tomography, the radiographer is able to control the thickness of the
tomographic slice by altering which of the following?
A. Exposure angle
B. Fulcrum height
C. Tube trajectory - CORRECT ANSWERS A. Exposure angle
On a radiograph of a shoulder, the greater tubercle is visualized in profile. Which
projection was taken? - CORRECT ANSWERS Anteroposterior (AP), external
rotation
Which factor will increase x-ray beam quantity at the image receptor (IR) without
increasing heat units produced by the tube? - CORRECT ANSWERS
Decreased filtration
Which position most accurately describes the Camp Coventry method for
demonstrating the intercondylar fossa of the knee? - CORRECT ANSWERS
Prone with the femur parallel to the image receptor
Which position of the elbow will clearly demonstrate the radial neck free of ulnar
superimposition? - CORRECT ANSWERS Lateral oblique
What would a continuous, fine, horizontal white line across the computed

Where should the radiographer direct the central ray for a posteroanterior (PA)
chest? - CORRECT ANSWERS Midsagittal plane and 18-20 cm below the
vertebral prominens
Why is it important for the radiographer to observe the milliampere seconds (mAs)
readout at the end of each exposure when using automatic exposure control (AEC)?
- CORRECT ANSWERS This value may be used as a basis for calculating
manual techniques
Pelvis routine calls for an anteroposterior (AP) with a perpendicular central ray (CR),
and an axial AP with a 40 degree cephalic angle. Using a caliper measurement, the
technique chart yields a perfect set of exposure factors for the perpendicular AP.
How will the necessary exposure factors for the axial differ from the perpendicular
AP? - CORRECT ANSWERS Greater measurement, higher kilovolts peak
(kVp) and milliampere-seconds (mAs)
Which characteristics are true of both x-rays and gamma rays? (Select the three
that apply.) - CORRECT ANSWERS Are low linear energy transfer (LET)
radiation, Are electromagnetic radiation, Damage biologic tissues through indirect
action
Which projection of the stomach demonstrates the duodenal bulb filled with barium
and free of superimposition? - CORRECT ANSWERS Posteroanterior (AP)
oblique projection, right anterior oblique (RAO) position
A radiographer critiques an anteroposterior (AP) image of the ribs. The left
sternoclavicular (SC) joint is demonstrated without vertebral column
superimposition. What should the radiographer do? - CORRECT ANSWERS
Rotate the patient to the right
Which projection is a radiographer performing if the patient's hand is turned in
extreme internal rotation, with the central ray directed perpendicular to the first
metacarpophalangeal joint? - CORRECT ANSWERS Anteroposterior (AP)
thumb

A lateral knee image reveals that the femoral condyles are not superimposed with
the medial condyle situated posteriorly. How should the radiographer correct this
image? - CORRECT ANSWERS Position patella closer to the image receptor
(IR)
Which is the proper amount and direction of heel rotation recommended for a
posteroanterior (PA) projection of the patella? - CORRECT ANSWERS 5 to 10
degrees laterally
What is the best projection to evaluate the coronoid process in profile? - CORRECT
ANSWERS Medial oblique elbow
A lateral scapula image demonstrates the lateral border of the scapula next to the
ribs and the vertebral border of the scapula demonstrated posterolaterally. How
should the radiographer correct this image? - CORRECT ANSWERS Decrease
patient obliquity
What is a method of electronic display resolution quality control testing? -
CORRECT ANSWERS Society of Motion Picture and Television Engineers
(SMPTE) test pattern
Which advantage does a 500 milliampere (mA) station have over a 200 mA station?
- CORRECT ANSWERS Increased photon flux to the image receptor (IR)
A patient is scheduled for an interventional radiological procedure that requires
general anesthesia. Who is the most appropriate person to obtain informed consent
for the procedure in this situation? - CORRECT ANSWERS Radiologist
At a 50 inch source-to-image-receptor-distance (SID), how closely must the x-ray
beam and the light field be aligned? - CORRECT ANSWERS 1 inch
Which may be effects of fetal irradiation? (Select the four that apply.) - CORRECT
ANSWERS Prenatal death, Growth retardation, Developmental abnormalities,
Childhood and early adult cancers
