Test your basic knowledge |

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

7. We ideally take a radiograph of the abdomen at the peak of inspiration






8. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






9. Is the device which restricts (narrows) the beam of x-rays as they leave the x-ray machine






10. These screens have increased definition/detail - need to have increased radiation exposure






11. Is the source of electrons






12. If the kVp is too low






13. Between density and kVp






14. A living animal - with tissue densities such as fat - muscle - fluid - and air






15. Calcium 'bridges' between adjacent vertebrae






16. Is to the right - it produces the electrons






17. MAs for extremities






18. With the heel effect - more x-rays tend to be produced toward the cathode end

20. Radiographic signs dont always agree with what






21. Infection of a disk - or bone near it






22. Types of cell damage






23. These screens are high speed - they decrease exposure - poorer detail - able to penetrate thicker areas






24. What is one of the most common areas of occurance for spinal problems ( 85% dachshunds)






25. What type of bone tumors started in the location they were first found






26. What spinal problem do doberman's get

28. AgBr + light =






29. With what kind of typical film do we get 95% exposure due to visible light and 5% is due to the x-rays directly






30. The x-ray machine we've been using has a rotating anode






31. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






32. The electrical current sent through the filament to cause this electron release is called






33. Collimator






34. This stage of pregnancy is the most dangerous for the fetus






35. Dislocations or separations






36. We should always try and stay How many feet from our x-ray machine






37. Is the measurement for the maximum energy available at that setting






38. Faster screens/less detail; slower screens/more detail






39. What is one of the most common area of occurance for spinal problems (15% dobermans)






40. To utilize this - you position the thickest part of the animal towards the cathode end of the x-ray tube






41. Why do we not give atropine with a contrast radiograph






42. When the density difference is great - there is
