RATIONALES
Which central ray (CR) angle is best for heavy, wide-hipped
patients for lateral lumbar spine projections?
A. 5 degrees cephalad
B. Perpendicular
C. 10 degrees caudad
D. 5 degrees caudad - ✔✔✔ Correct Answer > D. 5 degrees caudad
With heavy, wide hipped patients, it is best to begin with a 5
degree caudal angle. Perpendicular CRs simply don't work well
with these patients. Extreme cases of wide hips may require
even more angle of 10 degrees caudad, but these will be the true
exception, rather than the rule. A cephalic angle would close the
joint spaces.

A radiographer critiques an image of an anteroposterior (AP)
pelvis. The left obturator foramen is narrower than the right.
What should the radiographer do?
A. Rotate the patient to the right.
B. Accept the image.
C. Rotate the patient to the left.
D. Internally rotate both feet - ✔✔✔ Correct Answer > A. Rotate the
patient to the right.
The patient is in a left posterior oblique (LPO) position, so the
patient should be rotated to the right to be in a true AP position.
The highest potential dose to the radiographer during c-arm
fluoroscopy originates from which source?
A. The side where x-rays exit the patient.
B. Leakage radiation from the image intensifier.
C. The side where x-rays enter the patient.
D. Leakage radiation from the x-ray tube. - ✔✔✔ Correct Answer > C.
The side where x-rays enter the patient.
,Page 3 of 106
The highest scatter dose during c-arm fluoroscopy is at the
entrance surface of the patient, closest to the x-ray tube.
How does the central ray (CR) for an anteroposterior (AP)
scapula differ from an AP shoulder x-ray?
A. 1 inch higher
B. CR is the same
C. 1 inch lower
D. Same level, medial - ✔✔✔ Correct Answer > C. 1 inch lower
Which projection best demonstrates the aortic impression on the
esophagus in an esophagram?
A. Left lateral
B. RAO
C. LAO
D. PA - ✔✔✔ Correct Answer > B. RAO
The best view of the aortic impression on the esophagus is
obtained in the RAO projection. This impression is hidden from
view in the LAO, PA, and left lateral.

Which patient body habitus may require the patient to be in the
Trendelenburg position during a small bowel series?
A. Hyposthenic
B. Asthenic
C. Sthenic
D. Hypersthenic - ✔✔✔ Correct Answer > B. Asthenic
Asthenic patients may be placed in Trendelenburg position to
separate overlapping loops of small bowel.
Which joint is the central ray (CR) entrance point for a
posteroanterior (PA) finger projection?
A. PIP
B. CMC
C. MCP
D. IP - ✔✔✔ Correct Answer > A. PIP
Where is the central ray (CR) directed for an anteroposterior
(AP) projection of the lower leg?
