Answer: B. Operate imaging equipment safely
Rationale: Radiologic technologists are responsible for producing high-quality diagnostic
images while ensuring patient safety.
2. What is the most important consideration when positioning a patient for an X-ray?
A. Patient comfort
B. Image quality
C. Radiation safety
D. All of the above
Answer: D. All of the above
Rationale: Proper positioning ensures diagnostic quality, minimizes repeat exposures, and
maintains patient comfort.
3. What does ALARA stand for in radiology practice?
A. As Low As Reasonably Achievable
B. All Levels Are Radiology Approved
C. As Long As Radiation Allowed
D. Advanced Level Radiology Assessment
Answer: A. As Low As Reasonably Achievable
Rationale: ALARA principle guides minimizing radiation exposure while achieving
diagnostic images.
4. Which of the following is a common side effect of contrast media?
A. Nausea
B. Rash
C. Itching
D. All of the above
,Answer: D. All of the above
Rationale: Contrast reactions can vary; mild reactions include nausea and rash, while
severe reactions are rare.
5. Which of the following is a contraindication for MRI?
A. Pacemaker
B. Metallic implants
C. Pregnancy (first trimester)
D. All of the above
Answer: D. All of the above
Rationale: MRI uses strong magnetic fields that can interfere with implanted devices or
affect fetal development.
6. What is the primary function of a collimator in X-ray imaging?
A. Limit scatter radiation
B. Improve image contrast
C. Reduce patient dose
D. All of the above
Answer: D. All of the above
Rationale: Collimators shape the X-ray beam, reducing exposure and improving image
quality.
7. Which of the following is considered ionizing radiation?
A. X-rays
B. Gamma rays
C. Ultraviolet radiation
D. Both A and B
Answer: D. Both A and B
Rationale: X-rays and gamma rays have sufficient energy to ionize atoms and affect
biological tissue.
8. What is the primary purpose of shielding in radiology?
A. Protect the patient from unnecessary exposure
B. Protect the technologist
, C. Both A and B
D. None of the above
Answer: C. Both A and B
Rationale: Lead aprons and barriers protect both patients and staff from scattered
radiation.
9. Which of the following is a common projection for chest X-rays?
A. PA (posteroanterior)
B. Lateral
C. AP (anteroposterior)
D. All of the above
Answer: D. All of the above
Rationale: Chest imaging uses multiple projections to visualize structures accurately.
10. What is the purpose of a grid in radiographic imaging?
A. Reduce scatter radiation
B. Increase contrast
C. Improve image quality
D. All of the above
Answer: D. All of the above
Rationale: Grids absorb scattered X-rays, enhancing contrast and diagnostic value.
11. Which of the following is a key principle in patient radiation protection?
A. Minimize exposure time
B. Maximize distance from source
C. Use shielding
D. All of the above
Answer: D. All of the above
Rationale: The three principles of radiation protection reduce risk to patients and staff.
12. Which of the following is the primary imaging modality for soft tissue visualization?
A. CT
B. MRI
