| 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 and in body? (Hint: 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 ED Physician order? | Tibia-Fibula |
| The physician is performing a lumbar myelogram and he getting ready to place the needle into 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 arrive to the ER with a large anterior deformity to the shoulder and the physician suspects an anterior dislocation. Which views are considered to be most appropriate in this scenario? | AP (Neutral rotation) and PA Oblique Scapular Y-View |
| You are performing a lumbar series and unable to get the spine horizontal for the lateral. What is the recommended CR angle to accommodate for this? | 5° for men, and 8° degrees caudal for women |
| When you have a properly positioned Oblique L-Spine, what makes up the body of the “Scotty Dog?” | Lamina |
