Accurate Questions With Correct Answers
The Material Commonly Used For Shielding Against Radiation Exposure In
Protective Aprons And Gloves Is:
A. Bismuth
B. Barium Impregnated Vinyl
C. Lead
D. Titanium
ANS: C. Lead
Rationale: Lead Is A Dense Material That Effectively Absorbs And Attenuates
Radiation, Making It Ideal For Use In Protective Aprons And Gloves To Shield
Healthcare Workers From Harmful Radiation Exposure.
The Radiation A Person Receives From The Sun (Cosmic Radiation) Is Categorized
As:
A. Medical Background Radiation
B. Natural Background Radiation
C. Radioactivity
D. Atmospheric Radiation
ANS: B. Natural Background Radiation
Rationale: Cosmic Radiation Is A Type Of Natural Background Radiation That
Comes From Outer Space, And All Humans Are Exposed To It Regularly.
What Is Postprocessing?
ANS: Manipulation Of Medical Images After They Have Been Acquired Through X-
Ray Exposure, To Improve Image Quality And Diagnostic Yield.
,Rationale: Postprocessing Techniques Enhance The Visibility And Diagnostic Value
Of Medical Images By Adjusting Contrast, Brightness, And Applying Filters.
What Is A Primary Barrier?
ANS: A Shielding Structure That Can Be Struck By The Primary X-Ray Beam
Exiting The X-Ray Tube.
Rationale: Primary Barriers Are Designed To Protect Against The Direct Radiation
From The X-Ray Source, Ensuring Safety In Radiographic Environments.
With Regard To The Alara Principle, The Responsibility Of The Radiographer Is To:
A. Obtain High-Quality Radiographs In An Efficient Manner
B. Keep Radiation Exposures At The Lowest Levels Possible
C. Assess Image Quality As A Function Of Dose
ANS: B. Keep Radiation Exposures At The Lowest Levels Possible
Rationale: Alara Stands For "As Low As Reasonably Achievable," Emphasizing The
Need To Minimize Radiation Exposure While Still Obtaining Necessary Medical
Images.
The Units Of Energy Equal To 1000 Electron Volts Are:
A. Air Kerma
B. Becquerel (Bq)
C. Kiloelectron Volts (Kev)
D. Photoelectric Absorption
ANS: C. Kiloelectron Volts (Kev)
Rationale: The Kiloelectron Volt (Kev) Is A Standard Unit Of Energy In The Field
Of Radiology, Specifically Used To Measure Photon Energy.
The Best Way To Communicate With A Non-English Speaking Person Is To:
A. Talk Louder Than Normal
, B. Show Frustration
C. Pantomime And Demonstrate What You Want
D. Immobilize Them
ANS: C. Pantomime And Demonstrate What You Want
Rationale: Non-Verbal Communication Through Gestures And Demonstrations Can
Effectively Convey Messages To Individuals Who Do Not Speak The Same
Language.
The Study Of Aging And Diseases Of Older Adults Is:
A. Gerontology
B. Pediatrics
C. Bariatrics
D. Obstetrics
ANS: A. Gerontology
Rationale: Gerontology Is The Multidisciplinary Study Of The Aging Process And
The Challenges That Older Adults Face.
A Computer Network For The Transmission, Viewing, And Storage Of Medical
Images Is Called The Pacs System.
ANS: True
Rationale: Pacs (Picture Archiving And Communication System) Is A Medical
Imaging Technology Used For Storing, Transmitting, And Managing Images, Which
Enhances Accessibility And Efficiency.
A Reliable Device To Measure Oxygen Saturation Level Of Arterial Blood Is A:
A. Spirometer
B. Stethoscope
C. Sphygmomanometer
D. Pulse Oximeter
