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




adiography?
A. To treat diseases using ionizing radiation
dy dy dy dy dy




B. To produceimages of internal structures for diagnosis
dy dy dy dy dy dy dy




C. To monitor patient vital signs
dy dy dy dy




D. To sterilize medical equipment
dy d y dy




Answer: B dy




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




ody structures, allowing physicians to detect and diagnose abnormalities. Options A
dy dy dy dy dy dy dy dy d y dy




, C, and D are unrelated to diagnostic imaging.
dy dy dy dy dy d y dy dy




2. What is the primary source ofionizing radiation in medical imaging?
dy dy dy dy dy yd dy dy dy dy




A. MRI scanner dy




B. X-ray tube dy




C. Ultrasound transducer dy




D. PET scanner dy




Answer: B dy




Rationale: The X- dy dy




ray tube generates ionizing radiation used in diagnostic radiography. MRI and ul

trasound use non- dy dy




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

3. How does the ALARA principle guide radiologic practice?
dy dy dy dy dy dy dy




A. Maximizing image quality regardless of dose dy dy dy dy dy




B. Minimizing radiation exposure while achieving diagnostic quality dy dy dy dy dy dy




C. Limiting patient interaction to reduce infection dy dy dy dy dy




D. Increasing exposure time for better penetration dy dy dy dy dy




Answer: B dy




Rationale: ALARA (“As Low As Reasonably Achievable”) ensures patient and st
dy dy dy dy dy dy d y dy dy dy




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

racture. Which safety measure is most important?
dy dy dy dy dy dy




A. Using the fastest imaging speed dy dy dy dy




B. Ensuring properpatient shielding and positioning dy dy dy dy dy




C. Increasing exposure to reduce repeat images dy dy dy dy dy




D. Allowing the patient to move during imaging dy dy dy dy dy dy




Answer: B dy




Rationale: Propershielding and positioning minimize unnecessary exposure and pro

5. Scenario:A 45-year- yd dy




old patient expresses concern about radiation exposure. How should the technol
d y dy dy dy dy d y dy dy dy dy




ogist respond? dy




A. Ignore their concerns;radiation is safedy dy dy dy dy




B. Explain that doseis minimized and benefits outweigh risks
dy dy dy dy d y dy dy dy




C. Refuse to perform the exam dy dy dy dy




D. Increase exposure to ensure better images dy dy dy dy dy




Answer: B dy




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

its, reducing anxiety and promoting informed consent.

6. Which professional organization establishes standards for radiologic

technologists?
A. WHO
B. ASRT
C. FDA
D. CDC
Answer: B dy




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

nal and professional standards. FDA regulates equipment, CDC focuses on infection co

, 7. Which imaging modality does not use ionizing radiation?
dy dy dy dy dy dy dy




A. CT scan dy




B. MRI
C. X-ray
D. Fluoroscopy
Answer: B dy




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




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

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




A. Muscle
B. Skin
C. Bone marrow dy




D. Cartilage
Answer: C dy




Rationale: Bone marrow contains rapidly dividing cells, making it highly sensitive t

9. Which factor primarily affects the quality of an X-ray image?
dy dy dy dy dy dy dy dy dy




A. Patient diet dy




B. Tube voltage and current

C. Room temperature dy




D. Technologist height dy




Answer: B dy




Rationale: Tube voltage (kVp) and current (mA) controlX-
