A battery powered, battery operated mobile xray unit can climb a maximum incline of how many degrees? |
Which type of mobile xray unit is self propelled? |
Which type of mobile xray unit is lighter in weight? |
True/false: C-arms are most generally stationary fluoro units used in surgery. |
True/false: C arm fluoro unit can be rotated a minimum of 180 degrees |
True/false: The AP projection with the xray tube placed directly above the anatomy during a C arm procedure is recommended to minimize OID |
True/false: Digital C arm units can store images on videotape or computer hard disk memory. |
What is the term for the process of holding one image on the C arm monitor while also providing continuous fluoro? |
Fracture through the pedicles of C2 |
Fracture of proximal half of ulna with dislocation of radial head |
Fracture due to a disease process |
Fracture resulting in an isolated bone fragment |
Subluxation of the radial head on a child |
Fracture along base of first metacarpal |
Fracture of distal phalanx with finger extended |
Also called a March fracture |
Also called a chauffeur's fracture |
True/false: Any trauma study requires at least two projections as close to 90 degrees opposite from eachother as possible |
True/false: On an initial study of a long bone, both joints should be included for each projection |
True/false: Collimation on trauma cases can lead to cutoff of key anatomy and pathology therefore it should be limited to the size of the IR |
The technologist must be at least _____ from the xray tube during a mobile |
True/false: Wearing a protective lead apron is optional if the tech is at least 8 feet away from both the tube and the patient during a mobile |
True/false: The exposure dose is greater on the image intensifier side than on the xray tube side with the C-arm in the horizontal configuration. |
True/false: A 30 degree tilt of the C arm from the vertical perspective will increase the dose by a factor of three to the head and neck region. |
What should be the final step that the tech takes before returning a trauma patient to the ER following a radiographic procedure? |
True/false: Angiography of the aortic arch for the trauma patient has declined due to increased use of CR angiography |
What is the correct term for the displacement of a bone from a joint? |
What is the correct term for a partial displacement? |
What term describes a poor alignment between the ends of a fractured bone? |
What term describes a bending of a distal fracture away from the midline? |
A tech using the C arm receives 125 mR/hr standing 2 feet from the patient. What is the exposure rate if the tech moves to a distance of 6 feet? |
A tech receives 30 mR/hr during C arm fluoro. What is the total exposure dose if the procedure takes 8 minutes of fluoro time? |
Radiologists often use the Salter Harris system to classify _____ fractures. |
A patient with a possible pleural effusion in the right lung enters the emergency room. The patient is unable to stand or sit erect. What position would best demonstrate this condition? |
Where is the CR centered for an AP semi-erect projection of the chest? |
A patient with a crushing injury to the thorax enters the emergency room. The patient is on a backboard and cannot be moved. Which projections can be performed to determine whether the sternum is fractured? |
