Which of the following demonstrates one end of a structure of interest appearing disproportionately
longer than the opposite end? - Correct answer-Elongation
(True/False)
The farther away a part is from the IR the more magnification is demonstrated. - Correct answer-True
The least amount of divergence in the xray beam is found: - Correct answer-The center of the central ray
Which of the following will help produce better spatial resolution? - Correct answer-Longer SID
When marking a lateral lumbar spine, it is preferred to place the marker anterior, why? - Correct
answer-The marker may be over-exposed and not seen on the image
Which of the following is true when using an angled CR beam? - Correct answer-As the angle increases,
the degree of anatomical part movement increases
,The technologist can compensate for increased OID by: - Correct answer-Increasing SID
To prevent unacceptable entrance skin dose, the skin to source distance should be no less than: -
Correct answer-12"
(True/False)
When an image is mismarked, the technologist should annotate directly over the marker - Correct
answer-False
(True/False)
The thicker the part being imaged, the smaller the collimator light field appears on the patients skin
surface thus requiring the technologist to decrease collimation - Correct answer-False
(True/False)
Clipping of required anatomy may occur due to divergence of the xray beam - Correct answer-True
Gonadal shielding should be used when the primary beam is within ______ inches of the gonads. -
Correct answer-2
Collimation best practices states the xray beam should be narrowed to include the required VOI and
_________. - Correct answer-0.5 - 1" of the surrounding anatomy
Good collimation practices will do all of the following except: - Correct answer-Reduce visibility of
recorded detail
(True/False)
When imaging long bones that require both joints to be included, open the collimation to include 1-2"
beyond each joint space. - Correct answer-True
(True/False)
,When the CR is angled, the structure situated farther away from the IR is projected in the direction of
the central ray angle. - Correct answer-True
(True/False)
Contrast masking may be used to replace collimation practices while performing the procedure. -
Correct answer-False
(True/False)
The image analysis form serves as a systemic approach to evaluate positioning and technical accuracy. -
Correct answer-True
(True/False)
The smaller the focal spot size used, the sharper the recorded detail. - Correct answer-True
(True/False)
A short SID and large OID will keep size distortion to a minimum. - Correct answer-False
Which of the following is the correct way to display a decubitus projection? - Correct answer-Display
with the side up as positioned
(True/False)
Radiation projection practices are important to prevent the occurrence of radiation induced
nonstochastic effects. - Correct answer-True
(True/False)
Foreshortening occurs when the CR and IR are perpendicular to each other but the part is inclined. -
Correct answer-True
When performing a chest xray on a patient with a suspected pneumothorax, which of the following
adjustments should be made? - Correct answer-Decrease kVp by 8%
, A PA chest is ordered for a patient with a history of a left pneumectomy. Which of the following
technical adjustments should be made? - Correct answer-Only the right AEC chamber should be
activated
A PA chest is ordered on a patient with a history of pleural effusion, which of the following technical
adjustments should be made? - Correct answer-Increase mAs by 35%
Which of the following describes the proper placement for a chest tube for air drainage? - Correct
answer-Anteriorly within the pleural space
For adults, the endotracheal tube should be positioned: - Correct answer-1 - 2" superior to the carina
Which of the following is used on neonates to measure oxygen saturation? - Correct answer-Arterial
umbilical catheters
Which of the following is inserted into the subclavian or jugular vein and extends to the superior vena
cava allowing infusion of substances too toxic for peripheral infusion? - Correct answer-Central venous
catheter
Which of the following is implanted in the anterior chest wall to detect heart arrhythmia and deliver a
shock to convert back to normal rhythm? - Correct answer-ICD
Rotation on a lateral chest projection is determined when: - Correct answer-More than 0.5" of space
exists between right and left posterior ribs
A lateral chest radiograph demonstrates the right hemidiaphragm inferior to the left. This is indicative
of: - Correct answer-Inferior midsagital plane was tilted toward the IR
Which of the following terms defines the cavity encasing the lungs? - Correct answer-Pleural space
Which of the following is an internal device located in the patients anterior chest wall with the end of
the catheter tips directed to the right atrium or to the right ventricle and supplies electrical stimulation
to maintain a regular heart rhythms? - Correct answer-Pacemaker
