Bontrager Chapter 15: Trauma, Mobile, and Surgical Radiography Questions With Correct Solutions, Already Passed!!

list the two primary types of mobile x-ray - Answer-battery driven and standard AC power non-motor drive t/f: a fully charged battery powered mobile unit has a driving range of up to 10 miles on level ground - Answer-true With battery-powered types, how long does recharging take if the batteries are fully discharged? - Answer-8 hours Which type of mobile unit is lighter in weight? - Answer-Standard power source, nonmotor drive what is the common term for a mobile fluoroscopy unit - Answer-c-arm what are the two primary components of mobile fluoroscopy unit - Answer-x-ray tube and image intensifier why should the mobile fluoroscopy unit not be placed in the AP projection - Answer-significant increase in exposure to head, eyes, and neck of operator With the tube and intensifier in a horizontal position, at which side of the patient should the surgeon stand if he or she must remain near the patient-the x-ray tube side or the intensifier side? Why? - Answer-on the intensifier side because radiation scatters farther on the tube side Of the two monitors found on most mobile fluoroscopy units, which one is generally considered the active monitor , the right or the left - Answer-left t/f the operator must determine image orientation on the mobile fluoroscopy monitors before the patient is brought into the room - Answer-truet/f all mobile digital fluoroscopy units include the ability to magnify the image on the monitor during fluoroscopy - Answer-true a 30 degree C-arm tilt from the vertical perspective increases exposure to the head and neck regions of the operator by a factor of ___ - Answer-four t/f AEC exposure systems are not feasible with mobile fluoroscopy - Answer-false Name the feature that allows an image to be held on the monitor while also providing continuous fluoroscopy imaging. - Answer-roadmapping t/f the intermittent mode used during most mobile fluoroscopy procedures is helpful during procedures to produce brighter images, but results in significantly increased patient exposure - Answer-false Which single term best describes the primary difference between trauma positions and standard positioning? - Answer-adaptation what should be done to achieve specific projections if the patient cannot move because of trauma - Answer-Move CR and IR around the patient to produce similar projections what is the minimum number of projections generally required for any trauma study - Answer-two 90 degrees from each other how many joints must be included for an initial study of a long bone - Answer-2 both joints T/F: A follow-up postreduction radiograph of the middle portion of long bones should be collimated closely to the fracture region. - Answer-false, include at least one joint t/f digital radiography is well suited for ED and mobile procedures - Answer-truet/f nuclear medicine is effective in diagnosing certain emergency conditions such as pulmonary emboli - Answer-true T/F: For trauma patients who cannot be moved for conventional diagnostic imaging, other modalities, such as ultrasound or nuclear medicine, may be used rather than trying to move the patient into specific positions. - Answer-false
