A KUB radiograph reveals that the gonadal shield is superior to the upper margin of the
symphysis pubis. The female patient has a history of kidney stones. What is the next
step the technologist should take? a. Accept the radiograph because the kidneys were

b. Repeat the exposure without using gonadal shielding
c. Repeat the exposure if the patient complains of pain in the lower abdomen
d. Repeat the exposure with gonadal shielding, but position it below the symphysis
pubis - ANS-Repeat the exposure without using gonadal shielding because the patient
may have renal calculi in the distal ureters and urinary bladder gonadal shielding cannot
be used

you proceed? - ANS-The referring physician that ordered the stress views on the ankle
should be the only one to manipulate the patient's foot and ankle to obtain these views;
it's not in the technologist's scope of practice to manipulate the foot and ankle for stress
views

patient is unable to stand or sit erect. Which of the following projections will best
demonstrate this condition?
a. Left lateral decubitus
b. Dorsal decubitus
c. AP supine
d. AP supine chest - ANS-Left lateral decubitus

pneumoperitoneum. The patient is able to stand. Which of the following projections will
best demonstrate this condition?
a. AP supine abdomen
b. Left lateral decubitus
c. Dorsal decubitus

most often performed for this condition?
a. Single contrast barium enema
b. Double contrast barium enema
c. Intubation small bowel series

35 degree AP axial projection
A patient has an intermedullary nail securing a fractured femur. What is critical in the
post-reduction images? - ANS-The entire orthopedic device must be included

Caldwell (AP axial) image?

A patient is being positioned for a routine scan of the brain.
Why is he asked to tuck his chin down toward his chest?
a. So that the scan time can be reduced
b. To allow immobilization sponges to be used
c. To reduce the radiation
d. To eliminate the need to tilt the gantry so that the axial scan mode can be used -
ANS-To reduce the radiation
The slice angle is determined by the position of the patient's head and the tilt of the
gantry. Having the patient tuck his chin down may allow a slice angle that avoids
scanning through the eye, thereby reducing radiation exposure to the lens. The lens of
the eye is known to be more sensitive to radiation

demonstrated? - ANS-The left side will be demonstrated (The side closest to the IR)
