The primary clinical indication for an operative cholangiogram is:

Initial 55 kV and 5 mAs. A fiberglass cast on the forearm requires what change in tech factors

95 kVp, 20mAs, 150 cm SID, 15 mR exposure. Same tech used @SID of 100cm, what is x-ray exposure

Fragment of bone that separates or pulls away by the attached tendon or ligament is a(n) ___ fx

150kVp, 50mAs, intensity of 40 mR. The x-ray intensity decreased to 22 mR, what is the new kVp?

Which of the following terms best describes a partial dislocation of a joint?

“Boost” exposures used during C-arm procedures are intended to:

Which fx is defined as being crushed at the site of impact, producing two or more fragments?

Only one joint needs to be included for follow-up studies of a long bone fracture

What describes a misalignment of a distal fracture fragment that is angled toward the midline?

Arthroplasty is a formal term describing a(n):

Which fx is often called a reverse Colles’ with anterior displacement of the distal radius?

How much rotation of the body is required for an AP oblique, lateral scapular Y projection?

A health professional who prepares the OR by supplying appropriate supplies and instruments is

With high level fluoro (HLF) the max exposure rate cannot exceed 20 R/min

75 kVp, 50mAs, xray intensity of 20 mR. If kVp is increased to 125 kVp, what is the intensity?

This C-arm orientation results in greatest exposure to the operator’s head region (w PT supine)

Which of the following is not an essential attribute for the surgical radiographer?

Postreduction projections of long bones require only the joint nearest to the fracture site.

At 36" SID, the rad dose is 100 R. What would the dose be in air if the SID was 72'??

Where should the operator stand when using a C-arm fluoro unit in a horizontal CR position?

Which cardinal rule of rad protection ismost effective in reducing exposure in mobile procedure

Typically, how much contrast media is injected by the surgeon during a cholangiogram?

Subluxation is best described as a:

___creates an x-ray beam that activates timed increments to reduce exposure during C-arm fluoro

The following methods will best reduce patient dose during a fluoroscopic procedure in surgery?

100 kVp, 25 mAs, with an x-ray intensity of 28 mR.If mAs is 35 mAs what will the intensity be?

Which of the following is not a fracture but a subluxation?

75 kVp, 60 mAs, intensity of 12 mR. If the mAs is decreased to 25 mAs, what willintensity be?

Both joints need to be included for a long bone trauma x-ray
