Test Bank Bontrager’s Textbook of Radiographic Positioning and Related
Anatomy 9th Edition by Lampignano Complete Exam Questions 50+ and
Answers A+
A radiologic technologist is preparing a patient for a PA chest radiograph. The
patient’s chin is not elevated properly and is superimposing the apices of the
lungs. What positioning adjustment should be made to correct this issue?
A. Lower the chin further
B. Elevate the chin slightly
C. Rotate the patient
D. Increase SID
Answer: B
Rationale: Elevating the chin removes superimposition of the mandible over the
lung apices, improving visualization.
During a lateral lumbar spine projection, the technologist notices that the
vertebral bodies are not superimposed. What positioning error is most likely
present?
1
,A. Incorrect centering
B. Patient rotation
C. Overexposure
D. Improper breathing
Answer: B
Rationale: Lack of superimposition of vertebral bodies indicates rotation rather
than a true lateral position.
A patient is positioned for an AP axial (Lordotic) chest projection. What is the
primary purpose of this projection?
A. Visualize heart size
B. Demonstrate lung apices free of clavicles
C. Evaluate diaphragm
D. Assess ribs
Answer: B
Rationale: Lordotic view projects clavicles above lung apices for clearer
visualization.
2
,A technologist is performing a lateral cervical spine projection but cannot visualize
C7-T1 clearly. What additional projection should be performed?
A. Swimmer’s lateral
B. AP axial
C. PA oblique
D. Towne projection
Answer: A
Rationale: Swimmer’s lateral is used to visualize the cervicothoracic junction.
A PA projection of the hand shows closed joint spaces. What positioning error
caused this?
A. Fingers flexed
B. CR not perpendicular
C. Excessive exposure
D. Motion artifact
3
, Answer: B
Rationale: Incorrect CR angulation can close joint spaces, reducing diagnostic
quality.
A patient is positioned for an AP projection of the humerus. What is the correct
positioning of the hand?
A. Fully pronated
B. Supinated
C. Neutral
D. Flexed
Answer: C
Rationale: Neutral position ensures proper alignment of epicondyles.
A lateral knee projection shows the patella not in profile. What is the likely cause?
A. Incorrect centering
B. Rotation of the knee
C. Improper exposure
