RAD 135 Exam 1
| Question | Answer |
|---|---|
| In an upright chest __________ are better visualized | Air/Fluid Levels |
| Why is an upright chest preferred to a supine chest? | The diaphragm will move to its lowest position |
| A PA chest shows symmetric clavicles, well defined lung markings and diaphragm, but 7 posterior ribs visible. What is most likely the issue? | Exposure was taken after suspended single inspiration |
| Superimposed posterior ribs on a lateral chest image indicate | Proper Positioning |
| Which factors are critical to demonstrating fluid levels within the chest ? | Patient as upright as possible or decubitus Horizontal Beam |
| The lungs are enclosed with a shiny, slippery lining called the | Pleura |
| Which condition represents the most likely indication for an anteroposterior (AP) chest projection with the patient in the left lateral decubitus position? | Effusion in left lung |
| A patient has a left anterior rib injury. In which position should the patient be placed for the oblique image? | 45° RAO |
| When the patient is properly positioned for a PA projection of the chest, the central ray will enter the body | Midline, at approximately the level of T7 |
| Ten posterior ribs are visible above the diaphragm on a chest x-ray. This most accurately indicates | Proper Inspiration |
| Exposure for a chest x-ray should be taken on | Second Suspended Inspiration to ensure full expansion of the lungs |
| The serous membrane covering the surface of the abdominal organs is called the | Visceral Pleritoneum |
| What plane is parallel to the Central ray during a lateral chest radiograph? | Coronal |
| What are the functional units of the lung? | Alveoli |
| When the upper lung fields appear underexposed on a lateral chest radiograph, it is usually caused by | Failure to raise the patient’s arms high enough |
| The internal cartilaginous ridge supporting the inferior trachea at the bifurcation is termed the | Carnia |
| Select the two statements that are true for PA oblique SC joints (body rotation method) | The affected side is closer to the IR The CR enters lateral of MSP on the elevated side |
| What is the recommended SID necessary to blur the posterior ribs on a PA oblique projection of the sternum? | 30 inches |
| If you are doing a lateral projection of the abdomen, where should the CR be centered provided you need to include the diaphragm? | Perpendicular to the IR and entering the MCP at the level 2 inches superior to the iliac crest. |
| How can a technologist demonstrate the side of interest on a lateral decubitus image? | The side of interest should be up if free air is suspected and down if fluid buildup is suspected, with radiographic marker on the upside |
| An image of an AP abdomen demonstrates elongation of the right iliac wing and narrowing of the left iliac wing. Which one of the following position errors produces this radiographic outcome | Rotation to the Right |
| Where is the center of the IR positioned for an AP abdominal image performed with the patient in the supine position? | Iliac Crests |
| The Abdominal cavity extends from the | Diaphragm to the True Pelvis |
| An air-fluid level cannot be seen on which of the positions of a standard abdominal series? | Supine Abdomen |
