COMPREHENSIVE RADIOGRAPHY PRACTICE TEST V1
(2025) | 191 QUESTIONS | WITH ACTUAL SOLUTIONS.
Where is edge enhancement post processing most helpful in digital
radiography? Answer - Low contrast situations
Which technique produces a 3 mR exposure to an IR plate if 70 kVp at 25 mAs
produces 1.6 mR?
(Hint: Times 25 by 1.25 because 2 mR is 25% greater than 1.6 mR) Answer - 70
kVp at 31.25 mAs
Which factor will decrease the patient's dose during fluoroscopy? Answer -
Bring the image intensifier as close as possible to the patient
Where is the safest place for the radiographer to stand during fluoroscopy?
Answer - 90 degrees and one meter from the patient
Which device temporarily stores and electric charge? Answer - Capacitor
What is the maximum speed of filament electrons as they travel toward the
anode? Answer - Half the speed of light
,On which system does hospital staff input new orders for radiologic
examinations? Answer - Hospital Information System
What may be effects of fetal irradiation?
(Four Apply) Answer - Prenatal Death
Growth Retardation
Childhood and early adult cancers
Spontaneous Abortion
In an x-ray tube, what is the source of electrons used to make x-rays? Answer -
Filament
What CR angle is best for heavy, wide-hipped patients for lateral lumbar spine
projections? Answer - 5 degrees caudad
What elbow projection will show the radial head freest of superimposition?
Answer - AP, External Oblique
Prior to performing a PA chest projections with automatic exposure control
(AEC), the radiographer discovers that the patient has had a right total
pneumonectomy. What technical consideration should be considered? Answer
- Selecting only the detector on the left side
What is the minimum thickness of lead required for protective lead curtains?
Answer - .25 mm lead equivalence
, Which positioning method is prescribed to demonstrate the right zygomatic
arch free of superimposition on an inferosuperior tangential projection?
Answer - Rotate the head to the right with the chin tilted to the right
What is the magnitude of the angle formed by the intervertebral foramina and
the MSP in the thoracic spine? Answer - 90 degrees
Which digital communication network is used to store patient billing

Why should CR IR's be erased if they haven't been used? Answer - Remove fog
from background radiation
Which term refers to the radiation that exits the x-ray tube through the
collimator? Answer - Primary
Place the types of contrast media in order of decreasing opacity: Answer -
Thick barium sulfate
Thin barium sulfate
Ionic, water soluble
Carbon Dioxide
How much can exposure to the lens of the eyes be reduced by utilizing the PA
projection of the cranium over the AP projection? Answer - 95%
