back
What are oblique cervical spine views used to assess? - ANSWER--
Zygapophyseal joints

Name all functional joint types? - ANSWER-- Synarthrosis
- Amphiarthrosis
- Diarthrosis
List the 6 types of Synovial joint movement? - ANSWER-- Gliding
- Hinge
- Pivot
- Ellipsoid
- Saddle
- Ball and socket
List the 4 image quality factors of a radiograph? - ANSWER-- Density
- Contrast
- Spatial resolution
- Distortion
What are 2 landmarks that should NEVER be palpated? - ANSWER-- Pubis
symphysis
- Ischial tuberosity
What is the position that demonstrates the apices of the lungs, without
superimposition of the clavicles? - ANSWER-Lordotic or Apical
,What is the rationale for positioning the hand in supination for the AP
projection of the forearm? - ANSWER-This prevents the ulna and radius from
crossing
How could the distal humerus be imaged in a lateral projection without rotating
the limb? - ANSWER-Cross table lateral projection or transthoracic projection
Which special projection of the hands is recommended for early detection of
rheumatoid arthritis? - ANSWER-AP oblique (Norgaard method) ball catchers
projection
A patient has an intermedullary nail securing a fractured femur. What is critical
in the post-reduction images? - ANSWER-The entire orthopedic device must be
included
What is the purpose of the CR angle on the lateral projection of the knee? -
ANSWER-To prevent magnification of the medial femoral condyle obscuring
the joint space
What can be done to image the thoracic spine with a more uniform density? -
ANSWER-The anode heel effect or a compensating filter
What changes in patient status should be evaluated on a patient with blunt
abdominal trauma? - ANSWER-Increasing abdominal distention and firmness
to touch (This is a sign of hemorrhage)
Which critical conditions may be masked if a patient is under the influence of
drugs or alcohol? - ANSWER-- Head injury
- Shock
What are the top two chronic conditions of persons older than age 65? -
ANSWER-- Arthritis
, - Hypertension
Why should the use of adhesive tape be avoided when working with geriatric
patients? - ANSWER-They often have thin, fragile skin that can be easily
damaged
Where would the cathode be placed, in reference to the patient, to take
advantage of the anode heel effect on a decubitus position for the chest? -
ANSWER-On the side that is down (Cathode end has more power)
What is the single most effective means of radiation protection for the
radiographer performing mobile procedures? - ANSWER-- Distance
- Must be 6 feet from the mobile x-ray tube
Which images might be improved by using a breathing technique? How are the
exposure factors manipulated to allow breathing during the exposure? -
ANSWER-Lateral cervicothoracic projection, mA is lowered and exposure time
is lengthened (Reciprocity law)
What accommodations are made for patients with cervical trauma? - ANSWER-
- Patients are in an immobilization device (collar) so the equipment will have to
move around the patient instead of us positioning them
- A lateral view must be taken first and cleared by a doctor before proceeding
with imaging
What fractures might be missed if the lateral projection does not demonstrate
the top of T1? - ANSWER-Clay shoveler's fracture
What additional projection is required if T1 is not demonstrated on the C-spine
lateral? - ANSWER-A lateral projection of the cervicothoracic spine
(Swimmers)
