| You have an upper abdominal image on a patient that has had a cholecystectomy. How would you be able to identify that on radiograph? | Look for surgical clips in the RUQ |
| You have been asked to perform an AP Axial projection of a patient's C-spine. Where will the CR be directed? | 15-20 degrees cephalic to enter at C4 |
| In relation to the spine, where will the cardiophrenic angles be located? | Medial aspect of the lungs |
| According to Merrill's Atlas, where will the CR be placed for an axiolateral oblique mandible projection of the ramus? | The region of interest |
| When setting up for a Tib/Fib or lower leg, where is the CR directed? | Mid-lower leg |
| Where is the only saddle joint located in the body? (Between which two bones?) | Trapezium and 1st Metacarpal |
| If the hand is fully extended, with the palmar surface of the hand flat against the IR, what position is the thumb in? | PA Oblique |
| Your patient has suspected hip injury and they are positioned on a backboard. The patient's right leg and foot are lying on its lateral side and you are about to position them. What should you do to complete the exam successfully? | Perform the exam without repositioning the leg |
| The ER patient has been suspected to have Osgood-Schlatter's Disease. What Radiographic exam might the ER Physician order? | Tibia-Fibula |
| The physician is performing a lumbar myelogram and he is getting ready to place the needle in the meningeal space. Which meningeal space is the contrast injected? | Subarachnoid |
| This particular disease process causes increased radiodensity in the lung fields on a radiograph due to inflammation and accumulation of fluid: | Pneumonia |
| What bones form the sinus tarsi? | The Talus and Calcaneus |
| If you are setting up to position for a lateral sternum, how will you instruct the patient to position their arms? | Behind the back |
| What would be the most likely cause of free intraperitoneal air on an AP Erect Abdomen radiograph? | Bowel Perforation |
| On a lateral chest x-ray, which hemidiaphragm will be higher? | Right hemidiaphragm |
| Patient arrives to the ER with a large anterior deformity to the shoulder and the physician suspects an anterior dislocation. Which views are considered to be the most appropriate in this scenario? | AP (Neutral Rotation) and PA Oblique Scapular Y-View |
| You are performing a lumbar series and are unable to get the spine horizontal for the lateral. What is the recommended CR angle to accommodate for this? | 5 degrees for men and 8 degrees for women, caudal |
| When you have a properly positioned Oblique L-spine, what makes up the body of the "scotty dog"? | Lamina |
| If the CR is directed 2 inches anterior to the ASIS and 1 1/2 inches inferior to the iliac crest, where is the CR in relation to the lateral L5/S1 Lumbosacral junction? | The CR is well anterior to the L5/S1 junction. |
| On a KUB radiograph, where are the psoas muscles located? | On either side of the L-spine, forming a triangular pattern |
| What bone is the coracoid process located on? | Scapula |
| A patient presents with a left axillary, 6th rib fracture. How will the best be demonstrated? | Upright AP & 45 degree LPO |

| An AP Oblique (Mortise) projection of the ankle demonstrates the distal fibula without talar superimposition and an open talofibular joint. What should be done next? | Nothing, no correction needs to be made |
| Patient presents to the ER because he smashed his index finger with a hammer. What type of fracture might show up on the radiographs? | Comminuted |
| When a PA Chest is positioned properly, where is the manubrium of the sternum seen on a sthenic patient? (What vertebral level) | T4 |
| When performing a portable CXR, fluid levels need to be demonstrated. What factor is most important in demonstrating this? | A horizontal CR |
