ARRT prep exam 2 Questions and
Correct solutions
Iron is an example of a _______________ material. - correct answers:Ferromagnetic
For trauma radiography, a radiographer could best acquire images of a lateral distal femur by: - correct
answers:acquiring a cross-table lateral femur with a lateromedial projection
Total brightness gain for the image intensifier is calculated by: - correct answers:flux gain multiplied by
minification gain.
A person with acute radiation syndrome does not demonstrate signs of illness during the ________
period. - correct answers:latent
An adult patient has diffuse erythema following a contrast injection. The technologist can apply all of the
following treatments to the patient EXCEPT: - correct answers:administering an epinephrine injection.
The number of signal selections sent from a photodetector to the analog-to-digital converter is known
as: - correct answers:sampling frequency.
________ has a threshold dose of 6 Gy to the whole body. - correct answers:The gastrointestinal
syndrome
The HVL for a 60 kVp beam is ________ of aluminum equivalent (Al/eq). - correct answers:The HVL for a
60 kVp beam is 1.3 mm of Al/eq.
The ________ grid pattern configuration transmits the greatest number of photons. - correct
answers:focused
A portable anteroposterior (AP) chest radiograph was acquired without a grid using a technique of 109
, kVp and 3 mAs. The image was repeated with a 12:1 grid. The new technique for the second image is: -
correct answers:Using the mAs - grid compensation formula and grid conversion factors, the mAs for the
second image is 15 mAs. The kVp does not change from 109.
Which of the following are rules of body mechanics that should be adhered to when moving objects or
patients in the radiology department? - correct answers:Push heavy objects; avoid pulling.
The Physician's Desk Reference is a resource for medication information that can tell the radiographer
specific drug information EXCEPT: - correct answers:the average price of a medication.
The correct angle of needle entry for an intramuscular injection of medication is: - correct answers:90
A tumor measures 10 inches on a femur radiograph. The femur was placed 6 inches from the image
receptor and the tube was placed at a 48-inch source-to-image distance from the image receptor. The
actual tumor size is: - correct answers:9 inches.
The SOD is determined to be 42 Inches. The magnification factor is then calculated to be 1.1. Using this
factor, the object size is found to be 9 inches.
On a parietoacanthial projection of the sinuses with the open-mouth Waters method variation,
the________ sinus is displayed through the patient's mouth on the image. - correct answers:sphenoidal
The top of the foot is the ________ surface. - correct answers:dorsal
The ________ tendon inserts on the radial tuberosity. - correct answers:biceps brachii
The penumbra for an image taken with a 2-mm effective focal spot, a source-to-image distance (SID) of
48 inches, and SOD of 40 inches is: - correct answers:0.4 mm.
Using the penumbra (focal spot blur) equation requires finding the OID. Once all factors are known and
computed the result is 0.4 mm of unsharpness.
