Which projection is a radiographer performing if the patient's hand
is turned in extreme internal rotation, with the central ray
directed perpendicular to the first metacarpophalangeal joint?
ANSWERS: Anteroposterior(AP) thumb.
A finished radiograph has marked quantum mottle. Positioning,
collimation, and identification markers are correct. Which action
should the
radiographer take?
ANSWERS: Repeat the image with an appropriate increase in technical
factors.
,A radiographer evaluates a posteroanterior (PA) chest radiograph. The
image demonstrates rotation, but the radiographer believes that the
rotation resulted from the patient's scoliosis. What would be
demonstrated on the
image to make the radiographer believe this is the case?
ANSWERS: O The distance between the lung margins and the spine
varies down the length of each lung.
Pediatric patients require special consideration and appropriate
radiation protection procedures because they are more vulnerable
to which?
ANSWERS: O Both the late somatic effects and genetic effects of
radiation,
,Which advantage does a 500 milliampere (mA) station have over a 200
mA station?
ANSWERS: Increased photon flux to the image receptor (IR).
Which type of exposure technique chart would allow the
radiographer to make small, fine adjustments for orthopedic
work?
ANSWERS: Variable kilovolts peak (kVp).
An electrically neutral sodium atom has 1 valence electron. What
chemical event happens when the sodium atoms encounter a
chlorine atom with 7 valence electrons?
ANSWERS: lonic bonding.
Under which condition might an x-ray photon be deviated from its
original direction?
ANSWERS: O Interaction occurs.
A patient is having a lengthy procedure done in the medical imaging
department. The patient seemed to be anxious at the beginning of the
procedure and starts wheezing. What should the radiographer do
next?
ANSWERS: O Ask the patient if they have a history of asthma.
, In the event that a pregnant patient is inadvertently irradiated, who
should perform the calculations necessary to determine fetal dose?
ANSWERS: Radiologic physicist.
Which statement is correct regarding the relationship of patient dose
to exposure index (EI)?
ANSWERS: OEl gives an approximation of the patient's dose.
If computed radiography (CR) imaging plates (IP) haven't been
used, how often should they be erased?
ANSWERS: O48 hours.
Which material is used most anode disks and is light, strong,
and heat-resistant?
ANSWERS: Molybdenum.
What could cause a computed radiography image with very
noticeable lines uniformly in the same direction over the entire
image? (Select the three that apply.)
ANSWERS: 1-Noise resulting from the plate reader electronics. 2-Grid
used with grid
frequency equal to the image reader's laser scan lines. 3-Grid
utilized with grid lines running parallel to the laser scan lines of the
image reader device.
