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.
1. X-ray gloves have to have....of lead equivalent






2. What needs to have high levels of x-ray to light conversion with the correct energy and color for the type of film used






3. If you use an mA of 300 - What time fraction must i use to get an mAs of 10?






4. Negative contrast agents appear what color on a radiograph






5. As this increases - the intensity of the x-ray beam decreases - so the beam intensity increases - and the mAs must decrease to compensate






6. The 2 types of collimators are






7. This gives you the desired mAs - and it gives less time for your patient to move






8. Less forgiving - high contrast - cannot tolerate changes in exposure or processing






9. A...is a series of lead strips on edge which only allow the primary x-rays - which are traveling in straight lines - reach the film






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






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






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






13. Between density and kVp






14. Measures the power of penetrability (quality) of the x-rays produced






15. Lung tissue appears black (radiolucent) on a radiograph






16. If the grid is stationary - more lines that are finer are less apt to show up on a radiograph - this is called....






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






18. Another result of the 20 degree angling






19. What is the term for the spotty appearance on the film due to the large crystals in the screens






20. Types of cell damage






21. The distance from the x-ray tube to the x-ray machine is the SID (source image distance) - or the FFD (also known as....)






22. The effective focal spot is approximately 1/3 the size of the actual focal spot






23. Within the collimator outlines just how much is collimated






24. To double the density






25. When a body part is greater than or equal to.....you should use a grid






26. Has a negative charge






27. Is influenced by quantity of x-rays(mAs) - quality of x-rays (kVp) - type and thickness of tissue being x-rayed






28. Must increase.....to compensate for x-ray absorption by the grid. (we triple our mAs)






29. Means more electrons will be released from the filament and directed at the anode






30. Animal has broken femur - it's ideal to have How many radiographs for diagnostic purposes






31. If perforation is suspected - what compound do we use when radiographing






32. Lead equivalent for thyroid sheild






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






34. Improper centering of grid is one reason for






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






36. The back of the cassette is made of lead to decrease....






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






38. What specific part of the eye is cloudy with a cataract






39. What type of bone tumors started elsewhere and spread to the location it was found






40. MAs for abdomen (standard mAs) x=?






41. There are......intensifying screens within a cassette






42. The greater the number of electrons released






43. If the thorax is greater than or equal to....you should use a grid






44. Safe Operating Procedures






45. MAs for extremities






46. Radiograph of a dogs skeleton has a long scale of contrast






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






48. This is inversely proportional to screen speed






49. Must be radiolucent






50. Infection of a disk - or bone near it
