1. Which of the following best describes the primary purpose of diagnostic r
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




adiography?
A. To treat diseases using ionizing radiation
1a 1a 1a 1a 1a




B. To produceimages of internal structures for diagnosis
1a 1a 1a 1a 1 a 1a 1a




C. To monitor patient vital signs
1a 1a 1a 1a




D. To sterilize medical equipment
1a 1 a 1a




Answer: B 1a




Rationale: Diagnostic radiography’s main purpose is to produce images of internal b
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




ody structures, allowing physicians to detect and diagnose abnormalities. Options A,
1a 1a 1a 1a 1a 1a 1a 1a 1 a 1a




C, and D are unrelated to diagnostic imaging.

2. What is the primary source ofionizing radiation in medical imaging?
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




A. MRI scanner 1a




B. X-ray tube 1a




C. Ultrasound transducer 1a




D. PET scanner 1a




Answer: B 1a




Rationale:The X- 1a 1a




ray tube generates ionizing radiation used in diagnostic radiography. MRI and ult
1 a 1a 1 a 1 a 1 a 1a 1 a 1a 1a 1a 1a




rasound use non- 1a 1a




ionizing energy, while PET uses radioactive tracers rather than producing radiatio

3. How does the ALARA principle guide radiologic practice?
1a 1a 1a 1a 1a 1a 1a




A. Maximizing image quality regardless of dose 1a 1a 1a 1a 1a




B. Minimizing radiation exposure while achieving diagnostic quality 1a 1a 1a 1a 1a 1a




C. Limiting patient interaction to reduce infection 1a 1a 1a 1a 1a




D. Increasing exposure time for better penetration 1a 1a 1a 1a 1a




Answer: B 1a




Rationale: ALARA (“As Low As Reasonably Achievable”) ensures patient and st
1a 1a 1a 1a 1a 1a 1 a 1a 1a 1a




aff receive the minimum radiation dosenecessary for diagnostic-quality images.

racture. Which safety measure is most important?
1a 1a 1a 1a 1a 1a




A. Using the fastest imaging speed 1a 1a 1a 1a




B. Ensuring properpatient shielding and positioning 1a 1a 1a 1a 1a




C. Increasing exposure to reduce repeat images 1a 1a 1a 1a 1a




D. Allowing the patient to move during imaging 1a 1a 1a 1a 1a 1a




Answer: B 1a




Rationale:Propershielding and positioning minimize unnecessary exposure and pro

5. Scenario:A 45-year- 1a 1a




old patient expresses concern about radiation exposure. How should the technol
1 a 1a 1a 1a 1a 1 a 1a 1a 1a 1a




ogist respond? 1a




A. Ignore their concerns;radiation is safe 1a 1a 1a 1a 1a




B. Explain that doseis minimized and benefits outweigh risks
1a 1a 1a 1a 1 a 1a 1a 1a




C. Refuse to perform the exam 1a 1a 1a 1a




D. Increase exposure to ensure better images 1a 1a 1a 1a 1a




Answer: B 1a




Rationale:Patients should be informed about the low doseand the diagnostic benef
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




its, reducing anxiety and promoting informed consent.

echnologists?
A. WHO
B. ASRT
C. FDA
D. CDC
Answer: B 1a




Rationale: The American Society of Radiologic Technologists (ASRT) sets educatio

1a 1a 1a 1a 1a 1a 1a




A. CT scan1a




B. MRI
C. X-ray
D. Fluoroscopy
Answer: B 1a




Rationale:MRI uses magnetic fields and radio waves, which are non-
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




ionizing. CT, X-ray, and fluoroscopyall use ionizing radiation.

8. What is the most radiosensitive tissue in the human body?
1a 1a 1a 1a 1a 1a 1a 1a 1a




A. Muscle
B. Skin
C. Bone marrow 1a




D. Cartilage
Answer: C 1a




Rationale:Bone marrow contains rapidly dividing cells, making it highly sensitive to
1a 1a 1a 1a 1a 1a 1a 1a 1a 1a 1a




ionizing radiation. Muscle, skin, and cartilage are less sensitive.
