LRA 223 EXAMS SCRIPT 2025/2026 QUESTIONS AND
SOLUTIONS GRADED A+
✔✔Why is acute extension of the head important during myelography? - ✔✔To prevent
contrast medium from entering the cerebral ventricles
✔✔Why does the radiologic technologist expose the C7-T1 interspace during a cervical
examination of a traumatic patient for a considerably longer time than usual? - ✔✔To
blur overlying lung structures
✔✔When imaging trauma patients, which radiographic examination is an exception to
the central ray part image receptor (CR-part-IR) alignment rule? - ✔✔Anteroposterior
(AP) axial oblique cervical spine

process

not a fracture of the acetabulum has occurred. Which projection will best demonstrate a
fracture of the acetabulum? Select all that apply. - ✔✔Posterior oblique pelvic projection
Posteroanterior (PA) axial oblique projection

✔✔Anteroposterior (AP) unilateral hip projection
✔✔Which statements apply to the male pelvis? Select all that apply. - ✔✔The ilia
appear less flared.
The pubic arch forms an acute angle.
The pelvis appears narrow and deep.
The shape of the inlet of the pelvis is heart shaped.
✔✔At which point should the central ray be directed in an anteroposterior (AP) pelvic
projection? - ✔✔Midway between the level of the anterior superior iliac spine and the
symphysis pubis

ventricles during myelography? - ✔✔Acute extension of the head

✔✔Intervertebral and costovertebral joints fuse
Inflammation progresses up the vertebral column
✔✔ How will the radiologic technologist position the C-arm fluoroscope in order to
obtain a posteroanterior (PA) projection of the patient's hip? - ✔✔Place the C-arm
between the patient's legs and center the image intensifier over and above the affected
hip
✔✔Which structures can be seen in anteroposterior (AP) axial outlet pelvic projection?
Select all that apply. - ✔✔Body of ischium
Ramus of ischium
Inferior rami of pubis
✔✔Which radiographic procedure is contraindicated in a patient who has increased
intracranial pressure? - ✔✔Myelography
✔✔How would the radiographer locate the hip joint without making the patient feel
uncomfortable? - ✔✔Palpate anterior superior iliac spine and 1.5 inches inferiorly and
medially
✔✔Which structures can be best demonstrated in an anteroposterior (AP) bilateral frog-
leg pelvic projection? Select all that apply. - ✔✔Acetabulum
