Correct Answers 2025-2026 Edition.
d - Answer Which of the following statements is NOT TRUE regarding anatomically
programmed radiography (APR)?
a. It can be used in conjunction with automatic exposure control (AEC)
b. APR allows for specific anatomical part selection
c. It displays manual exposure factors
d. APR prevents making adjustments to mAs
c - Answer The minimum length of the exposure cord for mobile x-ray units is:
a. 12 feet
b. 9 feet
c. 6 feet
d. 3 feet
c - Answer ________ are used to reduce the effect of scatter radiation.
a. Intensifying screens
b. Compensating filters
c. Radiographic grids
d. Compression devices
a - Answer Anteroposterior (AP) oblique images of the chest can be used when a patient is too
ill for upright or prone positioning. When the patient is in a 45° right posterior oblique (RPO)
position:
a. the right lung field is best displayed
b. the left lung field is best displayed
c. both lungs are well displayed
,c - Answer When evaluating an image of the pelvis, the radiographer notes that there is
maximum demonstration of the lesser trochanters. Was this patient positioned correctly for a
non-trauma AP projection of the pelvis?
a. Yes, because the lesser trochanters are demonstrated in profile.
b. Yes, because there is no foreshortening of the femoral necks.
c. No, because the femoral necks are not parallel with the image receptor.
d. No, because the femora have not been rotated enough in the lateral direction
c - Answer The radiographer can best control the production of scatter radiation by:
a. increasing the kVp
b. adding filtration
c. reducing field size
d. using a grid
b - Answer When a patient has parenteral administration of medication, the medication is NOT
delivered via:
a. injection into a muscle
b. the gastrointestinal system
c. the sublingual area
d. injection into a vein
d - Answer A 58-year-old man is in the radiology department for an upper GI series (UGI). He
has followed nothing by mouth (NPO) instructions and has diabetes. When the radiographer
stands the patient to position him for the upright portion of the study, the patient says he is
dizzy and feeling weak. He took his morning medications along with his normal dose of insulin.
The patient MOST likely is experiencing ________, and the radiographer should ________.
a. hyperglycemia; give the patient a cup of water to drink
b. hypoglycemia; give the patient a carbonated drink such as seltzer water or a soda
c. hyperglycemia; give the patient something salty to eat
, a. make the patient more comfortable
b. prevent the contrast medium from entering the cerebral ventricles
c. prevent the contrast medium from entering the subarachnoid space
d. prevent the contrast medium from entering the thoracic region of the spine.
d - Answer The ________ risk model predicts that excess cancer deaths from irradiation will
increase over time as the naturally occurring risk increases with age in the nonirradiated
population.
a. absolute
b. lethal dose (LD) 50/30
c. threshold response
d. relative
c - Answer To demonstrate the zygapophyseal joints of the thoracic vertebrae, a radiographer
should place the patient in a ________ position.
a. lateral
b. 45° oblique
c. 70° oblique
d. PA
d - Answer Which of the following statements is TRUE regarding source-to-image distance
(SID)?
a. decreasing SID decreases Compton scatter
b. decreasing SID decreases magnification
c. increasing SID increases receptor exposure
d. increasing SID decreases distortion.
a - Answer For conventional fluoroscopy, the light intensities must be converted by the
________ to be viewed on a television monitor.
