| during atrial systole, blood flows into the | left ventricle via the bicuspid valve; right ventricle via the tricuspid valve |
| how should a chest exam to rule out air-fluid levels be obtained on a trauma pt | inlude a lateral chest exam -dorsal decubitus position |
| use of iodinated constrast agents w/ pts taking metformin | metformin is used to help lower blood sugar levels in type 2 diabetic pts; pts on metformin who have IV iodinated contrast are at risk for renal failure; metformin should be withheld for 48 hours after IV iodinated contrast studies. |
| erect PA, chin extended, OML 15 deg from horizontal | to get PA axial Caldwell |
| Position is used to demo the frontal & ethmoid sinuses; the ethmoid sinuses are seen near the medial aspect of the orbits; the perpendicular plate is seen in midline of the nasal cavity | PA axial Caldwell |
| to avoid excessive metacarpophalangeal joint overlap in the oblique projection of the hand | oblique the hand no more than 45 deg1 |

| AP knee on pt 21 cm from ASIS to tabletop, CR is | 0 degrees (perpendicular) |
| olecranon process is best seen in | medial oblique |
| on a lateral LSP, can see | intervetrebral foramina & pedicles best |
| which of tangential axial projections of the patella is complete relaxation of the quadriceps femoris required for an accurate diagnosis | supine flexion 45 degrees (Merchant) |
| which projections can be used to supplement the traditional "open-mouth" projection when the upper portion of the odontoid process cannot be well demonstrated | AP or PA through the forament magnum |
| floor of cranium includes all the following bones | 2 temporals, ethmoid, sphenoid |
| lateral projection of the hand in extention is often recommended to evaluate | foreign body or soft tissue |
| the condition that results from a persistent fetal foramen ovale is | an atrial septal defect |
| which of the following projections or positions will best demonstrate subacromial or subcoracoid dislocation | PA oblique scapular Y |

| what positions can be used to demo the axillary ribs of the right thorax | LAO & RPO |
| in which projection of the foot are the interspaces between the first & second cuneiforms best demonstrated | lateral oblique foot |
| the sternal angle is at approx. the same level as the | T5 |
| which of the following structures is (are) located in the right upper quadrant (RUQ) | gallbladder, hepatic flexure |
| to demo esophageal varices, the pt must be examined in | the anatomic position |
| the tissue that occupies the central cavity w/in the shaft of a long bone in an adult is | yellow marrow |
| all the following stuctures are assoc. w/ the posterior femur except | intertrochanteric line {anterior femur popliteal surface, intercondyloid fossa, linea aspera} |
| which of the following prejections of the ankle would best demo the mortise | medial oblique 15-20 degrees |
| which of the following bony landmarks is in the same transverse plane as the symphysis pubis | prominence of the greater torchanter |
| a radiolucent sponge can be placed under the pt's waist for a lateral projection of the lumbosacral spine to | make the vertebral column parallel w/ the IR; place the intervertebral disk spaces perpendicular to the IR |
| to reduce the amount of scattered radiation reaching the IR in CR/DR imaging of the lumbosacral region, which of the following is recomended | close collimation & lead mat on table posterior to the pt |
| which of the following is distal to the tibial plateau | tibial condyles & tibial tuberosity |
