The recommended source-to-image distance (SID) for a lateral projection of the C-spine
is ________ inches.

A fracture of the distal radius with posterior displacement is a ________ fracture.

All of the following are inappropriate sites for venipuncture EXCEPT FOR:
arms on the side of a mastectomy.
edematous areas.
sites above an intravenous access device.
the dorsal side of the wrist. - Answers - the dorsal side of the wrist.
An increase in image contrast will result from increasing which of the following?
OID
SID
kVp
focal spot size - Answers - OID
(SID and focal spot size have no effect on image contrast. Increasing the kVp will lower
image contrast due to an increase in scatter radiation reaching the receptor. Increasing
OID increases image contrast due to the air gap, resulting in less scatter reaching the
receptor.)
All of the following are quality control (QC) tests for photostimulable imaging detectors
EXCEPT FOR:
uniformity.
spatial resolution.
luminance.
erasure thoroughness. - Answers - luminance.
If a fluoroscopic procedure takes 1 hour to perform, and the exposure rate is 48
mrem/hr, the patient dose for a procedure time of 30 minutes would be ______ mrem.
