1. Which of the following best describes the primary purpose of diagnosti
X@ X@ X@ X@ X@ X@ X@ X@ X@ X@
c radiography?
X@
A. To treat diseases using ionizing radiation
X@ X@ X@ X@ X@

X@ X
@ X@ X@ X@ X@ X@
C. To monitor patient vital signs
X@ X@ X@ X@
D. To sterilize medical equipment
X@ X@ X@
Answer: B X@
Rationale: Diagnostic radiography’s main purpose is to produce images of intern
X@ X@ X@ X@ X@ X@ X@ X@ X@ X@
al body structures, allowing physicians to detect and diagnose abnormalities. Op
X@ X@ X@ X@ X@ X@ X@ X@ X@ X @
tions A, C, and D are unrelated to diagnostic imaging.

2. What is the primary source of ionizing radiation in medical imaging?
X@ X@ X@ X@ X@ X
@ X@ X@ X@ X@
A. MRI scanner X@
B. X-ray tube X@
C. Ultrasound transducer X@
D. PET scanner X@
Answer: B X@
Rationale: The X- X

3. How does the ALARA principle guide radiologic practice?
X@ X@ X@ X@ X@ X@ X@
A. Maximizing image quality regardless of dose X@ X@ X@ X@ X@
B. Minimizing radiation exposure while achieving diagnostic quality
X@ X@ X@ X@ X@ X@
C. Limiting patient interaction to reduce infection
X@ X@ X@ X@ X@
D. Increasing exposure time for better penetration X@ X@ X@ X@ X@
Answer: B X@
Rationale: ALARA (“As Low As Reasonably Achievable”) ensures patient an

X@ X@ X@ X@ X@ X@ X@
A. Using the fastest imaging speed
X@ X@ X@ X@

X@ X
@ X@ X@ X@
C. Increasing exposure to reduce repeat images X@ X@ X@ X@ X@
D. Allowing the patient to move during imagingX@ X@ X@ X@ X@ X@
Answer: B X@
Rationale: Proper shielding and positioning minimize unnecessary exposure and

protect radiosensitive tissues. Options A, C, and D can increase radiation risk or
X@ X @ X@ X@ X@ X@ X@ X@ X@ X@ X @ X@
degrade image quality.

old patient expresses concern about radiation exposure. How should the tech
X @ X@ X@ X@ X@ X@ X@ X@ X@ X@
nologist respond? X@
A. Ignore their concerns; radiation is safe
X@ X@ X
@ X@ X@
B. Explain that dose is minimized and benefits outweigh risks
X@ X@ X
@ X@ X @ X@ X@ X@
C. Refuse to perform the exam X@ X@ X@ X@
D. Increase exposure to ensure better images
X@ X@ X@ X@ X@

X@
A. WHO
B. ASRT
C. FDA
D. CDC
