1. Which of the following best describes the primary purpose of diagnostic
x# x# x# x# x# x# x# x# x# x# x#
radiography?
A. To treat diseases using ionizing radiation
x# x# x# x# x#
B. To produce images of internal structures for diagnosis
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 internal
x# x# x# x# x# x# x# x# x# x#
body structures, allowing physicians to detect and diagnose abnormalities. Option
x# x# x# x# x# x# x# x# x# x #
s A, C, and D are unrelated to diagnostic imaging.
x# x# x# x# x# x# x # x# x#
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# x#
ray tube generates ionizing radiation used in diagnostic radiography. MRI and
x# x# x # x # x # x# x# x# x# x# x#
ultrasound use non- x# x#
ionizing energy, while PET uses radioactive tracers rather than producing radiat
x# x# x# x# x# x# x# x# x# x#
ion in a tube.
x # 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 and
x# x# x# x# x# x# x # x# x# x
staff receive the minimum radiation dose necessary for diagnostic-
# x# x# x# x# x# x# x# x#
quality images. x#
,4. A radiologic technologist is preparing to image a patient with a suspected
x# x# x# x# x# x# x# x# x# x# x#
fracture. Which safety measure is most important?
x# x# x# x# x# x# x#
A. Using the fastest imaging speed
x# x# x# x#
B. Ensuring proper patient shielding and positioning x# x# x# x# x#
C. Increasing exposure to reduce repeat images x# x# x# x# x#
D. Allowing the patient to move during imaging x# x# x# x# x# x#
Answer: B x#
Rationale: Proper shielding and positioning minimize unnecessary exposure and p
x# x# x# x# x# x # x# x# x#
rotect radiosensitive tissues. Options A, C, and D can increase radiation risk or de
x# x# x# x# x# x# x# x# x# x# x# x# x#
grade image quality. x# x#
5. Scenario:A 45-year- x# x#
old patient expresses concern about radiation exposure. How should the techn
x # x# x# x# x# x# x# x# x# x#
ologist 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#
Answer: B x#
Rationale: Patients should be informed about the low dose and the diagnostic be
x# x# x# x# x# x# x# x# x# x# x# x#
nefits, reducing anxiety and promoting informed consent.
x# x# x # x# x# x#
6. Which professional organization establishes standards for radiologic
x# x# x# x# x# x#
technologists?
x#
A. WHO
B. ASRT
C. FDA
D. CDC
Answer: B x#
Rationale: The American Society of Radiologic Technologists (ASRT) sets educat
x# x# x# x# x# x# x# x# x#
ional and professional standards. FDA regulates equipment, CDC focuses on infectio
x# x# x# x# x# x # x# x# x# x#
n control, WHO on global health.
x # x# x# x# x#
, 7. Which imaging modality does not use ionizing radiation?
x# x# x# x# x# x# x#
A. CT scan x#
B. MRI
C. X-ray
D. Fluoroscopy
Answer: B x#
Rationale: MRI uses magnetic fields and radio waves, which are non-
x# x# x# x# x# x# x# x# x# x#
ionizing. CT, X-ray, and fluoroscopy all use ionizing radiation.
x# x# x# x# x# x# x# x #
8. What is the most radiosensitive tissue in the human body?
x# x# x# x# x# x# x# x# x#
A. Muscle
B. Skin
C. Bone marrow x#
D. Cartilage
Answer: C x#
Rationale: Bone marrow contains rapidly dividing cells, making it highly sensitive
x# x# x# x# x# x# x# x# x# x# x
to ionizing radiation. Muscle, skin, and cartilage are less sensitive.
# x# x # x# x# x# x# x# x# x#
9. Which factor primarily affects the quality of an X-ray image?
x# x# x# x# x# x# x# x# x#
A. Patient diet x#
B. Tube voltage and current
x# x# x#
C. Room temperature x#
D. Technologist height x#
Answer: B x#
Rationale: Tube voltage (kVp) and current (mA) control X-
x# x# x# x# x# x# x# x#
ray energy and photon quantity, directly affecting image quality.
x# x# x# x# x # x# x# x #
10. How often should radiologic equipment be tested for quality assurance?
x# x# x# x# x# x# x# x# x#
A. Daily
B. Monthly
C. Annually
D. Only when malfunction occurs
