When preparing to add antiseptic iodine to a sterile field. Why must some of the liquid be poured into the sink before adding the remainder to the sterile container?
a. to wash the container's lip to prevent contamination
b. to prevent splashing of the liquid onto the sterile tray
c. to allow the technologist to determine the consistency of the liquid
d. to remove any solidified particles from the liquid - ACCURATE ANSWER-a. to wash the container's lip to prevent contamination (this maintains the sterile field)
Why is the maximum injection pressure of an automatic injection device preset during contrast media administration?
a. to prevent vessel damage
b. to control contrast volume
c. to allow bolus tracking
d. to maintain contrast viscosity - ACCURATE ANSWER-a. to prevent vessel damage
The QC technologist performs testing after images acquired in the past week demonstrate exposure inconsistencies which kVp accuracy test reading at 80 kVp would require corrective action?
a. 70 b. 72
c. 74
d. 76 - ACCURATE ANSWER-a. 70 (this is greater than the acceptable limit of 10%) A football player with broad shoulders presents with an obvious separation of the AC joint. What upright bilateral AC joints projection should be taken to best demonstrate the
condition?
a. with weights at 180 cm
b. without weights at 180 cm
c. with weights at 100 cm
d. without weights at 100 cm - ACCURATE ANSWER-a. with weights at 180 cm (using weights will best demonstrate the separation, and the longer SID reduces magnification which increases image quality)
What area of the gown is considered part of the sterile field?
a. the cuffs of the sterile gown
b. the entire front of the gown
c. the entire gown, front and back
d. the front of the gown, waist to shoulder - ACCURATE ANSWER-d. the front of the gown, waist to shoulder
What test must be performed first to ensure the validity of a mA linearity test result?
a. the light-filed congruency
b. HVL
c. timer accuracy
d. reproducibility - ACCURATE ANSWER-c. timer accuracy (The time and kVp accuracy must be verified prior to evaluating mA linearity)
What demonstrates minimal foreshortening of the femoral neck on an Axiolateral hip image?
a. the greater and lesser trochanter are on the same transverse level b. the lesser trochanter is proximal to the greater trochanter c. the greater trochanter is proximal to the lesser trochanter
d. the lesser trochanter is demonstrated in profile posteriorly - ACCURATE ANSWER-a.
the greater and lesser trochanter are on the same transverse level (this will verify that the CR is perpendicular to the femoral neck and the IR is parallel to the femoral neck)
Mr. Rogers presents with fixation devices protruding from the inferior aspect of his heel. The foot is flexed 70 degrees. Calcaneus images have been ordered. How should the technologist direct the CR for axial projections?
a. 40 degrees caudad
b. 40 degrees cephalad
c. 60 degrees cephalad
d. 60 degrees caudad - ACCURATE ANSWER-c. 60 degrees cephalad (The angle for a 90 degree flexed foot should be 40 degrees to the long axis of the foot. the angle must increased by 20 degrees (90-70=20) to compensate for lesser dorsiflexion. 40+20 = 60 degrees)
What will best demonstrate any medial or lateral displacement of a fracture of the ramus
of the mandible?
a. AP axial (Towne) b. Axiolateral oblique
c. Lateral
d. Panorex (orthopantomogram) - ACCURATE ANSWER-a. AP axial (Towne)
which of the following would demonstrate air/ fluid levels in the abdomen on an ICU patient who must remain supine?
a. left lateral decubitus
b. right lateral decubitus
c. dorsal decubitus
d. AP - ACCURATE ANSWER-c. dorsal decubitus
