  • 5. 
    When viewing a radiograph of a laterally positioned animal:
    • A. 

      The head should be at the top of the viewbox

    • B. 

      The head should face the viewer's left with the spine at the top

    • C. 

      The head should face the viewer's right with the spine at the top

    • D. 

      The head should face the viewer's left with the spine at the bottom

  • 6. 
    An overexposed film appears _______; to correct this, ___________.
    • A. 

      Too dark; increase mAs or kVp

    • B. 

      Too light; increase mAs or kVp

    • C. 

      Too light; decrease mAs or kVp

    • D. 

      Too dark; decrease mAs of kVp

  • 7. 
    What action should be taken if it is difficult to see anatomic silhouettes on an abdominal film and the film is too light? Why?
    • A. 

      Increase kVp by 10% to 15%; shorten wavelength increase penetrating power

    • B. 

      Increase mAs by 10% to 15%; increase the number of x-rays reaching the film

    • C. 

      Increase mAs by 30% to 50%; increase density

    • D. 

      Decrease mAs by 30% to 50%; lengthen wavelength and decrease penetrating power

  • 8.

      Increase kVp by 10% to 15%

    • C. 

      Increase mAs by 10% to 50%

    • D. 

      Increase kVp by 30% to 50%

  • 9. 
    A thoracic film is too dark. The bone tissue is relatively white. What is the next step?
    • A.

    • C. 

      Decrease mAs by 15%

    • D. 

      Decrease mAs by 50%

  • 10. 
    How does kVp affect scatter radiation?
    • A. 

      As kVp increases, scatter radiation decreases

    • B. 

      KVp has no effect on scatter radiation

    • C. 

      As kVp increases, scatter radiation can increase
