rationales (Chapter 1-12
Which of the following demonstrates one end of a structure of interest appearing disproportionately
longer than the opposite end? - Correct answer-Elongation
(True/False)

When marking a lateral lumbar spine, it is preferred to place the marker anterior, why? - Correct
answer-The marker may be over-exposed and not seen on the image
Which of the following is true when using an angled CR beam? - Correct answer-As the angle increases,

(True/False)
When an image is mismarked, the technologist should annotate directly over the marker - Correct
answer-False
(True/False)

Correct answer-True
(True/False)
The smaller the focal spot size used, the sharper the recorded detail. - Correct answer-True
(True/False)
A short SID and large OID will keep size distortion to a minimum. - Correct answer-False
Which of the following is the correct way to display a decubitus projection? - Correct answer-Display
with the side up as positioned
(True/False)
Radiation projection practices are important to prevent the occurrence of radiation induced
nonstochastic effects. - Correct answer-True
(True/False)
Foreshortening occurs when the CR and IR are perpendicular to each other but the part is inclined. -
