| Which of the following positions should be employed to obtain a radiographic image on a pt that has injured their ant 5th rib? 1. Erect PA 2. AP w/inspiration 3. Prone w/expiration | 1 & 2 |
| A radiographic image of the C-spine is obtained in the AP axial obl proj. This projection is commonly used for the evaluation of the: | Intervertebral foramina farthest from the IR |
| A radiographic image of the L-spine is obtained in the lat proj. This proj is most often requested to demo the: 1. Transverse processs of the vertebrae 2. Spinous processes of the vertrae 3. Height of the vertebral disc space | 2 & 3 |
| A radiographic image of the T-spine is obtained in the lat proj. If the lower vertebral column is not elevated to the horizontal position, the CR should be directed to the lvl of T7 at a: | 10-15° Cephalic |
| A radiograhpic image of the odontoid process is obtained in the AP(Fuchs) proj. The chin should be extended until: | The tip of the chin & mastoid process at vertical |
| A radiographic image of the costal jts is obtained in the AP axial proj for the demonstration of rheumatoid spondylitis. The CR is directed to enter the midsagittal plane 5 cm above the xiphoid process at a: | 20° cephalic |
| An image of the sternoclavicular jts is obtained in the axiolateral (Kurz Bauer) proj. The pt is placed in the lat recumbent position on their affected side w/the arm raised. The CR is directed thru the sternoclavicular jt closest to the IR at a: | 15° caudal |
| A radiographic image of the cervical spine is obtained in the lateral proj. The use of a radiographic grid is generally NOT required because of the scatter reduction that occurs: | From the use of the natural air gap |
| A radiographic image of the C-spine is obtained in the AP axial proj. A 15-20° cephalic angulation of the CR should be employed to better define the: | Intervertebral disk spaces |
| In an AP axial proj of the T-spine. The pt is placed in the rt lat recumbent position & rotated ant 20°. The CR is directed through T7. The structures best demonstrated would be the: | Rt zygapophyseal articulations |
| A radiographic image obtained in the PA axial obl (Kovacs) proj is most often taken to demonstrate the: | L5-S1 interspace |
| A radiographic image of the C-spine is obtained in the AP (Ottonello) proj while the pt is asked to open & close their mouth during the exposure. This maneuver is employed in the evaluation of: | The entire C-spine |
| A radiographic image of the symphysis pubis is taken in the PA (Chamberlain) proj w/the pt erect. This weight-bearing position is used to evaluate abnormal slippage of the: | Sacroiliac jts |
| A radiographic image of the C-spine is obained in the AP axial proj to demonstrate the lower cervical vertebrae. The CR should be directed 15° cephalic to enter at the: | Thyroid cartilage |
| What projection is most commonly used to more closely align the intervertebral disk spaces of the L-spine w/the divergence of the x-ray beam? | PA proj |
| A radiographic image of the entire spine is obtained to evaluate a pt w/lateral scoliosis. What proj can be used to reduce the radiation dosage to the thyroid, gonads & breasts of the pt? | PA proj |
| A radiographic image of the atlas & axis is obtained in the AP (open mouth) proj. In order to keep the tongue in the floor of the mouth the pt is instructed to: | Softly phonate the "ah" during the exposure |
| A radiographic image of the L-spine is obtained on a female pt in the lateral proj. If the spine is not adjusted to the horizontal plane for the exposure, the CR shoudl be directed: | 8° caudal |
| A radiographic image of the axillary portion of the right ribs can be best demonstrated in the: | PA obl (LAO) proj |
