Test Bank Bontrager’s Textbook of Radiographic Positioning and Related
Anatomy 9th Edition by Lampignano Complete Exam Questions 80+ and
Answers A+
A radiologic technologist is preparing to perform an AP projection of the scapula.
The patient is unable to abduct the arm due to trauma. What alternative
positioning should be used to best visualize the scapula?
A. PA projection with arm abducted
B. Lateral scapula projection (Y position)
C. AP projection without arm movement
D. Oblique projection of the shoulder
Answer: C
Rationale: If the patient cannot abduct the arm, an AP projection without
movement is performed, though some superimposition may remain.
During a PA chest radiograph, the technologist observes that the medial ends of
the clavicles are not equidistant from the vertebral column. What does this
indicate?
A. Proper positioning
1
,B. Patient rotation
C. Incorrect exposure
D. Motion artifact
Answer: B
Rationale: Unequal clavicle spacing from the spine indicates rotation, which can
distort diagnostic interpretation.
A patient is positioned for an AP axial coccyx projection. What is the correct
central ray angle?
A. 10° cephalad
B. 10° caudad
C. 15° cephalad
D. 15° caudad
Answer: B
Rationale: A 10° caudad angle projects the coccyx free of superimposition.

,A lateral lumbar spine radiograph shows intervertebral foramina not open. What
is the likely cause?
A. Incorrect centering
B. Patient rotation
C. Improper breathing
D. Overexposure
Answer: B
Rationale: Rotation prevents foramina from appearing open in a lateral
projection.
A technologist performs an AP projection of the forearm. What is essential for
proper positioning?
A. Elbow flexed
B. Wrist and elbow in same plane
C. Hand pronated only
D. Shoulder rotated
3
, Answer: B
Rationale: The forearm must be fully extended with wrist and elbow in the same
plane to avoid distortion.
A patient is positioned for a lateral chest radiograph. The posterior ribs are not
superimposed. What adjustment is needed?
A. Increase exposure
B. Correct patient rotation
C. Adjust CR angle
D. Raise arms higher
Answer: B
Rationale: Superimposition of posterior ribs indicates a true lateral position.
A radiograph of the foot shows elongated metatarsals. What positioning error
occurred?
A. Excessive CR angulation
B. Insufficient CR angulation
