T/F the C-arm fluoroscopy unit can be rotated a maximum of 180°
True
T/F the AP projection with the x-ray tube, placed directly above the anatomy during a C arm procedure is recommended to minimize 0ID
False
T/F digital C arm units can store images on video tape or computer, hard disk memory
True
What is the term for the process of holding one image on the C arm monitor while also providing continuous fluoroscopy
Roadmapping
Fracture through the pedicles of C2
Hangman
Fracture of proximal half of ulna with dislocation of radial head
Monteggia
Fracture resulting from a disease process

Fracture a long base of first metacarpal
Bennett
Fracture of distal phalanx with finger extended
Baseball
Also called a march fracture

Hutchinson
T/F any trauma study, requires at least two projections as close as possible to 90° opposite from each other
True
T/F on an initial study of a long bone both joints should be included for each projection
True
T/F collimation on trauma cases can lead to cut off of key anatomy and pathology. Therefore, it should be limited to the size of the IR.
False
The technologist must be at least_____ from the x-ray tube during a mobile radiographic procedures
6 feet
T/F wearing a protective lead apron is optional if the technologist is at least 8 feet from both the x-ray tube, and the patient during a mobile radiographic procedure
False
T/F the exposure dose is greater on the image intensifier side, then on the x-ray tube side with the C arm in the horizontal configuration
False
T/F a 30° tilt of the C arm from the vertical perspective, increases the dose by a factor of three to the head and neck region
False
What final step should the technologist take before returning a trauma patient to the emergency room following a radiographic procedure?
Ensure side rails are up on the patient cart
T/F The number of angiography’s of the aortic arch for the trauma patient has declined because of the increased use of CT angiography
True
What is the correct term for the displacement of a bone from a joint?
Dislocation or luxation
What is the correct term for a partial displacement?
Subluxation
Which of the following fracture terms are describes a situation in which the ends of fragments are aligned, but are pulled apart and are not in contact with each other
