Trauma Radiography!
Ch 18 Trauma, Mobile, & Surgical
| Question | Answer |
|---|---|
| What are the types of x-ray systems? | Battery-driven,Battery-Operated, Standard Power Source, Capacitor-Discharge, non-motor units, and Mobile C-Arm |
| Battery-Operated systems have a maximum incline of how many degrees? | 7 degrees |
| Battery-Operated systems can be plugged in for recharging when it is not being used and can be recharged at how many volts? | 110 or 220 Volts |
| Battery-Operated when charging with a 110-volt, 5-amp outlets, the charging time is about how many hours? | 8 hours |
| How many monitors are generally used with the Mobile C-Arm? | Two |
| What is the distance one should stand when operating a C-Arm? | 6 feet |
| What are the three positioning principles for trauma and mobile radiography? | Two projections 90 degress to each other with true cr-part-ir alignment, Entire structure or trauma area on image receptor, and Maintain the safety of the patient, health care workers, and the public |
| Small to medium plaster cast | Increase mAs 50 to 60 percent or +5 to 7 kv |
| Large plaster cast | Increase mAs 100 percent or +8 to 10 kv |
| Fiberglass cast | Increase mAs 25 to 30 percent or +3 to 4 kv |
| For postreduction radiographs after the addition of a small to medium cast, the kVp should be increased by: | 5 to 7 |
| A varus deformity indicates that the: | Distal fracture fragments are angled toward the midline of the body |
| An incomplete fracture on only one side of the bone is termed a(n): | Greenstick fracture |
| A fracture involving the base of the 5th metacarpal is termed: | Boxer’s fracture |
| Apposition or the relationship of the long axes of fracture fragments may be classified as: | Anatomic, Distraction, and Bayonet |
| The partial separation of the bones forming a joint is termed: | Subluxation |
| Examples of incomplete fractures include: | Torus and Greenstick |
| The Salter-Harris system is used to rate fractures classified as: | Epiphyseal |
| A standard power source, capacitor-discharge, non–motor-driven mobile unit may be operated using: | 110 volts and 15 amps |
| A fluoroscopic technique in which a static fluoroscopic image is held on the monitor screen while dynamic fluoroscopy continues is termed: | Road mapping |
| Which of the principles of radiation protection is most effective in reducing exposure to the technologist? | Distance |
| A fracture in which the fracture lines radiate from a central point is termed: | Stellate |
| Which fracture involves the distal fibula? | Pott’s |
| A butterfly fracture consists of | Two fragments positioned laterally to a main wedge-shaped fragment |
| Nursemaid's elbow is a subluxation of the: | radial head |
| The term contusion is synonymous with the term: | Bruise |
| A C-arm should not be rotated 180 degrees to reverse the positions of the x-ray tube and intensifier due to increased: | OID and Personnel radiation exposure |
| Battery-driven and operated mobile x-ray units are powered by: | 10-16 12V batteries |
| Trauma radiography requires: | Inclusion of the joint nearest the injury True CR and IR alignment Two projections 90° from each other |
| CR vertical results in | least exposure to operator |
| CR 30 degree from vertical | increase exposure to operator |
| CR horizontal | least exposure at intensifier side |
| AP projection | not recommended |
| A forced wrenching or twisting of a joint that results in a tearing of supporting ligaments | Sprain |
| An injury which there is no fracture or breaking of the skin | Contusion |
| A break in the bone | Fracture |
| Loss of alignment of the fracture | Angulation |
| Varus | Lateral apex |
| Valgus | Medial apex |
| A fracture in which the bone does not break through the skin | Simple (closed) fracture |
| A fracture in which a portion of the bone protrudes the skin | Compound (open) fracture |
| A fracture that does not traverse through entire bone (not broken into two pieces) | Incomplete (partial) fracture |
| Bone is splintered or crushed at the site of impact | Comminuted fracture |
| What are the three types of comminuted fractures | Segmental, butterfly, and splintered |
| One fragment is firmly driven into the other | Impacted fracture |
| Fracture of the wrist in which the distal radius is fractured with the distal fragment displaced posteriorly | Colles Fracture |
| A fracture of the wrist with a distal fragment of the radius displaced anteriorly | Smith's Fracture |
| Fracture through the pedicles of the axis | Hangman's Fracture |
| Fracture of the promixal half of the ulna and dislocation of the radial head | Monteggia's Fracture |
| Vertebral body collapses | Compression Fracture |
