RADT 1010 Final Exam 2024-2025 100%Correct Questions and Answers| +A Grade
1. The Use Of X-Rays To Create A Medical Image On Patients Is Referred To As:
A) Radiography
B) Ultrasound
C) Mri (Magnetic Resonance Imaging)
D) Ct Scan (Computed Tomography)
ANSWER: A)
Rationale: Radiography Specifically Refers To The Technique Of Using X-Rays To
View The Internal Structure Of The Body. It Is A Foundational Imaging Modality In
Medicine, Allowing For The Visualization Of Bones, Organs, And Other Tissues.
Other Options Like Ultrasound, Mri, And Ct Scans Utilize Different Technologies
And Principles For Imaging.
2. Particular Care Must Be Taken When Using Radiation For Medical Imaging. This
Is The Result Of Radiation's Ability To Create __________ In Human Tissue And
Possible Biochemical Changes.
A) Ionizations
B) Thermal Effects
C) Mechanical Vibrations
D) Chemical Bonds
ANSWER: A)
Rationale: Ionizations Refer To The Process By Which Radiation Can Remove
Tightly Bound Electrons From Atoms, Leading To Charged Particles (Ions). This Can
Cause Damage To Dna And Other Critical Cellular Components, Potentially Leading
To Adverse Health Effects Such As Cancer. Thermal Effects And Mechanical
,Vibrations Do Not Primarily Relate To The Harmful Impacts Of Radiation Used In
Imaging.
3. In The Diagnosis Of Patient Disease States, Physicians Can Select From An Array
Of Medical Diagnostic Modalities. A Few Of These Involve The Use Of Ionizing
Energy To Create A Medical Image. If A Physician Is Concerned About The Use Of
Ionizing Radiation, He Or She May Choose To Order Any Of The Following
Diagnostic Modalities Except:
A) Radiography
B) Nuclear Medicine
C) Ultrasound
D) Ct Scan
ANSWER: A)
Rationale: Radiography, Which Utilizes X-Rays, Is A Form Of Ionizing Radiation. If
A Physician Is Concerned About Ionizing Radiation, They Might Avoid Ordering
Radiography As Well As Ct Scans, Which Also Use Ionizing Radiation. Nuclear
Medicine Involves Radioactive Materials, Thus It Also Falls Under This Category. In
Contrast, Ultrasound Is A Safe Imaging Modality That Does Not Involve Ionizing
Radiation, Making It The Preferred Choice For Those Concerned About Radiation
Exposure.
4. The Greek Physician Hippocrates Is Regarded As The Father Of Western
Medicine. All Of The Following Choices Represent His Medical Beliefs Except The:
A) Importance Of Clinical Observation
B) Role Of Natural Causes In Disease
C) Important Medical Value Of Sorcery And Witchcraft
D) Emphasis On Ethical Practices In Medicine
ANSWER: C)
,Rationale: Hippocrates Is Known For Advocating A Rational And Observational
Approach To Medicine, Emphasizing Natural Causes For Diseases Rather Than
Supernatural Explanations Like Sorcery Or Witchcraft. His Work Laid The
Groundwork For Modern Medical Ethics And Clinical Practices, Focusing On
Observation And Logical Reasoning Over Mystical Explanations.
5. Throughout The History Of Medicine, Remarkable Achievements Have Been
Recorded. These Events Have Led To Our Current Understanding Of The Human
Organism And Disease. As This Research Continues, Much Of It Will Most Likely
Focus On:
A) Human Genes And Genetic Engineering
B) Herbal Medicine And Traditional Remedies
C) Surgical Techniques
D) Radiological Advancements
ANSWER: A)
Rationale: The Field Of Genetics Has Gained Immense Traction In Recent Years,
Particularly With Advancements Such As Crispr And Personalized Medicine.
Research Focusing On Human Genes And Genetic Engineering Holds The Potential
To Revolutionize The Treatment Of Various Diseases, Including Genetic Disorders,
Cancers, And Other Chronic Conditions. While Surgical Techniques And
Radiological Advancements Are Important, They Do Not Address The Foundational
Biological Understanding That Genetics Provides.
6. Wilhelm C. Roentgen's Discovery Of "The X-Ray" Is Regarded As One Of
Medicine's Most Significant Achievements. Although His Discovery Was Accidental,
His Early Research Was So Thorough That No Significant Findings Have Been
Added To His Original Theories. One Of The Most Famous Early Images He Created
Was An X-Ray Image Of His:
A) Daughter's Foot
, B) Wife's Hand
C) Mother's Skull
D) Friend's Chest
ANSWER: B)
Rationale: Wilhelm Roentgen Took One Of The First X-Ray Images Of His Wife’s
Hand, Famously Capturing The Image Of Her Wedding Ring And Bones. This Image
Not Only Showcased The Potential Of X-Ray Technology But Also Marked The
Beginning Of A New Era In Medical Imaging. The Other Options Are Not
Historically Significant In Relation To Roentgen's Discovery.
7. A Valuable X-Ray Procedure Used To Diagnose A Myocardial Infarction Would
Be:
A) Chest X-Ray
B) Coronary Arteriography
C) Mri Of The Heart
D) Echocardiogram
ANSWER: B)
Rationale: Coronary Arteriography, Also Known As Coronary Angiography, Is A
Specialized X-Ray Technique That Visualizes The Coronary Arteries Using Contrast
Dye. It Is Particularly Valuable In Diagnosing Blockages Or Abnormalities That
Could Lead To A Myocardial Infarction (Heart Attack). While Chest X-Rays And
Other Imaging Modalities Provide Some Information About The Heart, They Are Not
As Specific Or Effective For Diagnosing Coronary Artery Disease.
8. All Of The Following Are True Of The Diagnostic Procedure Of Mammography
Except:
A) The Procedure May Be Performed Using A General Radiographic Machine.
B) It Is Used To Detect Breast Cancer At An Early Stage.
