CHAPTER 1: INTRODUCTION TO RADIOLOGIC SCIENCE
1. Which of the following best describes the primary purpose of diagnostic
radiography?
A. To treat diseases using ionizing radiation
B. To produce images of internal structures for diagnosis
C. To monitor patient vital signs
D. To sterilize medical equipment
Answer: B
Rationale: Diagnostic radiography’s main purpose is to produce images of internal body
structures, allowing physicians to detect and diagnose abnormalities. Options A, C, and D are
unrelated to diagnostic imaging.
2. What is the primary source of ionizing radiation in medical imaging?
A. MRI scanner
B. X-ray tube
C. Ultrasound transducer
D. PET scanner
Answer: B
Rationale: The X-ray tube generates ionizing radiation used in diagnostic radiography. MRI
and ultrasound use non-ionizing energy, while PET uses radioactive tracers rather than
producing radiation in a tube.
3. How does the ALARA principle guide radiologic practice?
A. Maximizing image quality regardless of dose
B. Minimizing radiation exposure while achieving diagnostic quality
C. Limiting patient interaction to reduce infection
D. Increasing exposure time for better penetration
Answer: B
Rationale: ALARA (“As Low As Reasonably Achievable”) ensures patient and staff receive
the minimum radiation dose necessary for diagnostic-quality images.

4. A radiologic technologist is preparing to image a patient with a suspected fracture.
Which safety measure is most important?
A. Using the fastest imaging speed
B. Ensuring proper patient shielding and positioning
C. Increasing exposure to reduce repeat images
D. Allowing the patient to move during imaging
Answer: B
Rationale: Proper shielding and positioning minimize unnecessary exposure and protect
radiosensitive tissues. Options A, C, and D can increase radiation risk or degrade image quality.
5. Scenario: A 45-year-old patient expresses concern about radiation exposure. How should
the technologist respond?
A. Ignore their concerns; radiation is safe
B. Explain that dose is minimized and benefits outweigh risks
C. Refuse to perform the exam
D. Increase exposure to ensure better images
Answer: B
Rationale: Patients should be informed about the low dose and the diagnostic benefits,
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
Rationale: The American Society of Radiologic Technologists (ASRT) sets educational and
professional standards. FDA regulates equipment, CDC focuses on infection control, WHO on
global health.
