,Chapter 1: Introduction to Radiologic and Imaging Sciences
1. A patient is anxious about undergoing an imaging procedure involving ionizing radiation. The
radiologic technologist reassures the patient by explaining that the procedure uses minimal
radiation. Which of the following is the most appropriate description of ionizing radiation?
A. Radiation that has no effect on tissues
B. Radiation that removes electrons from atoms
C. Radiation that cannot penetrate the skin
D. Radiation that is absorbed entirely by bones
Rationale: Ionizing radiation has enough energy to remove electrons from atoms, potentially
causing damage to tissues, which is why minimal exposure is always preferred (B). It can
penetrate the skin and may be absorbed differently by various tissues, including bones.

2. What is the primary role of a radiologic technologist during an imaging procedure?
A. Diagnosing imaging results
B. Positioning the patient and operating imaging equipment
C. Determining the appropriate contrast medium
D. Performing surgery on the patient
Rationale: The radiologic technologist's primary role is to position the patient and operate the
imaging equipment during the procedure (B). Diagnosis and other medical decisions are made by
physicians.

3. A radiologic technologist explains the importance of ALARA to a patient. What does ALARA
stand for?
A. As Long As Radiation is Administered
B. All Levels of Radiation Are Acceptable
C. As Low As Reasonably Achievable
D. Average Levels of Radiation Achieved
Rationale: ALARA stands for "As Low As Reasonably Achievable" (C), emphasizing the
importance of minimizing radiation exposure to both patients and healthcare workers.

4. Which of the following professionals is primarily responsible for interpreting the results of
radiologic images?
A. Radiologist
B. Radiologic technologist
C. Nurse practitioner
D. Physician assistant
,Rationale: A radiologist (A) is a medical doctor who specializes in interpreting radiologic
images and diagnosing conditions based on those images.

5. A radiologic technologist is preparing a patient for a CT scan. Which of the following
instructions is most important to give the patient?
A. "You will need to remove all metal objects, including jewelry."
B. "You may eat a large meal before the procedure."
C. "You will need to hold your breath for 30 minutes."
D. "You can bring your phone into the scanner."
Rationale: Removing metal objects (A) is essential because metal can interfere with imaging
results in CT scans. The other options are incorrect or unrealistic.

6. Which of the following best describes the importance of patient positioning during
radiographic procedures?
A. It reduces radiation exposure.
B. It ensures accurate imaging and diagnostic results.
C. It eliminates the need for contrast media.
D. It improves patient comfort but does not affect the outcome.
Rationale: Proper patient positioning (B) is critical for obtaining accurate imaging and
diagnostic results. Incorrect positioning can lead to distorted or unclear images, which may affect
diagnosis.

7. What is the most important consideration when communicating with patients about an imaging
procedure?
A. Using medical terminology to explain the process
B. Speaking as quickly as possible to save time
C. Ensuring the patient understands the procedure and consents to it
D. Giving minimal information to avoid overwhelming the patient
Rationale: Ensuring that the patient fully understands the procedure (C) and provides informed
consent is the most important aspect of communication. Clear and simple language should be
used to avoid confusion.

8. Which of the following imaging modalities uses magnetic fields and radio waves to produce
detailed images of the body?
, A. CT
B. MRI
C. Ultrasound
D. Nuclear Medicine
Rationale: MRI (B) uses magnetic fields and radio waves to create detailed images of internal
structures. CT (A) uses X-rays, ultrasound (C) uses sound waves, and nuclear medicine (D) uses
radioactive tracers.

9. A patient undergoing a diagnostic procedure asks the radiologic technologist whether the
procedure will expose them to radiation. Which of the following procedures does NOT involve
ionizing radiation?
A. X-ray
B. CT scan
C. MRI
D. Fluoroscopy
Rationale: MRI (C) does not involve ionizing radiation; it uses magnetic fields and radio waves.
The other listed procedures involve ionizing radiation.

MSC: Patient Education
10. A radiologic technologist is assisting with a fluoroscopy procedure. Which of the following
is true about fluoroscopy?
A. It uses a continuous X-ray beam to create moving images.
B. It produces static images similar to X-rays.
C. It only uses sound waves for imaging.
D. It is used solely for imaging bones.
Rationale: Fluoroscopy (A) uses a continuous X-ray beam to create moving images, allowing
real-time visualization of internal structures. It differs from static imaging modalities like
traditional X-rays.
DIF: Comprehension
TOP: Imaging Techniques
MSC: Radiologic Technology
11. When using contrast media in imaging procedures, what is the primary purpose of these
substances?
A. To reduce the radiation dose
B. To increase patient comfort during the procedure
C. To improve the visibility of internal organs and structures
D. To eliminate the need for positioning
Rationale: Contrast media (C) improve the visibility of internal organs and structures by
highlighting specific areas during imaging. It does not reduce radiation or eliminate positioning
needs.
