1. Radiologic Physics:
Question: What is the primary purpose of the X-ray tube’s cathode in
radiography?
a) To convert electrical energy into X-rays
b) To focus the X-ray beam
c) To produce electrons for the anode
d) To filter the X-ray beam
Answer: c) To produce electrons for the anode
Rationale: The cathode contains the filament, which, when heated, emits
electrons that are directed toward the anode. The anode then decelerates these electrons, resulting in the production of X-rays.
2. Anatomy and Positioning:
Question: What is the correct positioning for a lateral chest X-ray?
a) Patient is positioned with the anterior chest against the image receptor
b) Patient stands upright with the left side against the image receptor 1 / 4
c) Patient is seated with the back against the image receptor
d) Patient lies on the table in a supine position
Answer: b) Patient stands upright with the left side against the image receptor
Rationale: For a lateral chest X-ray, the patient should stand with the left side against the image receptor to allow for accurate imaging of the chest anatomy, ensuring the right and left lung fields are properly viewed.
3. Patient Care and Safety:
Question: When assisting a patient with mobility issues in a wheelchair, what is the most important safety consideration?
a) Make sure the wheelchair is locked before assisting the patient
b) Ensure the patient has their seat belt on
c) Use only one person to assist the patient
d) Avoid using the footrests on the wheelchair
Answer: a) Make sure the wheelchair is locked before assisting the patient
Rationale: Locking the wheelchair ensures that it remains stationary while
assisting the patient, preventing falls and ensuring the patient’s safety.
4. Radiation Protection:
Question: Which of the following is the most effective method for reducing
radiation exposure to the patient?
a) Using the lowest possible exposure settings 2 / 4
b) Increasing the exposure time
c) Increasing the kilovoltage (kVp)
d) Reducing the focus-film distance
Answer: a) Using the lowest possible exposure settings
Rationale: The best method for reducing radiation exposure is to use the lowest
possible exposure settings while still obtaining a diagnostic-quality image. This minimizes the patient's radiation dose.
5. Medical Terminology:
Question: The term “radiolucent” refers to materials that:
a) Absorb X-rays
b) Appear white on a radiograph
c) Allow X-rays to pass through them
d) Block the passage of X-rays
Answer: c) Allow X-rays to pass through them
Rationale: Radiolucent materials, such as air, allow X-rays to pass through and
appear dark or black on a radiograph.
6. Radiologic Physics:
Question: What is the effect of increasing the kVp (kilovolt peak) on X-ray
production?
- / 4
a) Decreases the number of X-rays produced
b) Increases the energy and penetrability of X-rays
c) Decreases the contrast of the image
d) Reduces patient exposure
Answer: b) Increases the energy and penetrability of X-rays
Rationale: Increasing the kVp increases the energy and penetrability of the X-
rays, allowing them to pass through the patient and reach the image receptor.
7. Anatomy and Positioning:
Question: For an AP (anteroposterior) projection of the abdomen, where should
the central ray be directed?
a) At the level of the iliac crests
- 2 inches above the iliac crests
c) At the xiphoid process
d) At the level of the ASIS (anterior superior iliac spine)
Answer: a) At the level of the iliac crests
Rationale: For an AP abdomen X-ray, the central ray is directed at the level of
the iliac crests to capture the entire abdominal cavity.
8. Patient Care and Safety:
Question: When performing an X-ray on a pregnant patient, what is the most
important consideration?
- / 4
