10 Free Radiography Practice Questions

1. If the patient exhibits cardiac or respiratory arrest while in the radiographer’s care, the radiographer should:

   1. A, B, and C
   2. Signal for an AED
   3. Assess patient respiration
   4. Assess patient circulation
   Show Answer & Explanation

   Correct answer: A, B, and C

   In as short as 3 to 5 minutes, deoxygenation can cause irreversible brain damage. It is essential the radiographer be skilled in CPR/BLS techniques while working in the healthcare setting. A patient who is in respiratory or cardiac arrest should be assessed for a clear airway, breathing, and adequate circulation. A single rescuer should signal for help and an AED. An adult patient requires 80 to 100 compressions per minute for a single rescuer technique, with 2 ventilations for every 30 compressions.

6. Which anatomical feature corresponds to the number 5 in this image?

   1. Inferior Articular Process
   2. Femoral Neck
   3. Sacral Foramina
   4. Superior Acetabular Rim
   Show Answer & Explanation

   Correct answer: Inferior Articular Process

   Number 5 in this AP view demonstrates the Inferior articular process. Answer Key: 1. Pedicle 2. Spinous process 3. Body of the vertebra 4. Diaphragm 5. Inferior articular process

7. The patient’s chart can serve as a method of communication between multiple healthcare providers. A radiographer would expect to find all of the following within a patient’s chart, except:

   1. The patient’s gender identity
   2. Consent forms
   3. Therapeutic reports
   4. Patient identifying information
   Show Answer & Explanation

   Correct answer: The patient’s gender identity

   Communication is a key aspect of healthcare, and a fluid communication and trade off between healthcare personnel allows for the patient to receive a high level of patient care. A patient chart or electronic health record can serve as a method of communication between multiple healthcare providers and may include information such as a patient’s medical history including recent lab work or medical imaging examinations, identifying patient information, therapeutic and diagnostic reports, and consent forms. A patient’s assigned (biologic) sex would fall under the scope of patient identifying information; personal sense of gender identity differs from assigned (biologic) sex.

8. The radiographer can ensure patient understanding by:

   1. A and B
   2. Explaining the procedure and patient expectations
   3. Permitting the patient to ask questions and responding to patient inquiries
   4. Asking the patient to verify their requisition
   Show Answer & Explanation

   Correct answer: A and B

   While asking the patient to verify their requisition will allow the patient to read the name of the examination ordered by their provider and ensure that their identifying information is correct, this would not ensure patient understanding of the nature of the examination. It is the responsibility of the technologist to thoroughly explain what the procedure entails and the patient expectations which must be followed to carry out the examination. The technologist should also permit the patient to ask questions for clarification and respond to any patient inquiries.

9. Which of the following contributes to the acceleration of electrons?

   1. High potential difference between the cathode and anode
   2. Magnetic properties of the target material
   3. Rotating anode component
   4. Stationary anode component
   Show Answer & Explanation

   Correct answer: High potential difference between the cathode and anode

   A focused electron beam travels from the cathode toward the anode. Electrons accelerate toward the anode end of the tube as a result of the high potential difference between the cathode and the anode. A rotating versus stationary anode would not contribute to the acceleration of electrons, but rather, the dissipation of heat.

10. Atoms with the same mass number and atomic number are called:

    1. Isomers
    2. Isotones
    3. Isobars
    4. Isotopes
    Show Answer & Explanation

    Correct answer: Isomers

    Isomers are atoms that have the same mass and atomic number. Atoms with the same atomic number, or number of protons, but distinct mass numbers are called isotopes. As a result, the number of neutrons in them varies. Isobars are groups of atoms with the same mass number but distinct atomic numbers. Isotones are atoms with distinct atomic numbers but the same neutron number.
