ANSWERS WITH RATIONALES NEWEST VERSION
,Chapter 1 — Introduction to Radiologic Science
1. A 28-year-old patient arrives for a chest x-ray. Which of the following best
describes the purpose of the radiographer’s role in image acquisition?
A. To interpret the radiograph and diagnose disease for the referring physician.
B. To produce diagnostic images of optimal quality while minimizing radiation
exposure to the patient.
C. To perform any invasive procedure necessary to obtain the image.
D. To ensure the patient signs a waiver accepting radiation risk prior to imaging.
Answer: B
Rationale: The radiographer’s primary duty is to produce diagnostic images of the
required anatomy with optimal image quality while adhering to radiation
protection principles (ALARA). Radiographers do not diagnose (A) — that’s the
physician’s role — nor perform invasive procedures unless trained and authorized
(C). Informed consent procedures (D) are institution- and procedure-dependent;
routine x-rays often don’t require a separate waiver.
2. Which historical development most directly allowed radiography to change from
a purely experimental field into a clinical tool?
A. Discovery of x-rays by Wilhelm Röntgen.
B. Introduction of digital detectors.
C. Establishment of radiation protection standards.
D. Development of fluoroscopy.
Answer: A
Rationale: The discovery of x-rays by Röntgen (1895) made imaging possible;
this discovery is the seminal event that allowed radiography to become a clinical
tool. Digital detectors (B) and fluoroscopy (D) were later technological advances.
Radiation protection (C) enabled safer practice but is not the initial enabler.
,3. A student radiographer is studying the core components of the radiologic
sciences. Which discipline focuses primarily on interactions between ionizing
radiation and living tissue?
A. Radiography.
B. Radiation biology.
C. Radiologic physics.
D. Radiologic technology management.
Answer: B
Rationale: Radiation biology studies how ionizing radiation affects living
organisms (cellular damage, deterministic/stochastic effects). Radiography (A)
pertains to image acquisition; radiologic physics (C) focuses on physical principles
of radiation production and detection; management (D) deals with administration.
4. Which of the following statements about evidence-based practice (EBP) in
radiologic technology is MOST accurate?
A. EBP relies solely on randomized clinical trials from medicine and is rarely
applicable to radiology.
B. EBP integrates clinical expertise, patient values, and the best available research
evidence to guide practice.
C. EBP means strictly following manufacturers’ equipment manuals for every
procedure.
D. EBP replaces clinical judgment entirely.
Answer: B
Rationale: EBP combines clinical expertise, current best evidence, and patient
preferences to make decisions. It’s not limited to RCTs (A), nor does it replace
judgment (D). Equipment manuals (C) are important but not the same as EBP.
5. Which professional organization is primarily responsible for developing
standards of practice and code of ethics for radiologic technologists in the United
States?
A. Food and Drug Administration (FDA).
B. American Registry of Radiologic Technologists (ARRT).
, C. American Society of Radiologic Technologists (ASRT).
D. International Atomic Energy Agency (IAEA).
Answer: C
Rationale: The ASRT (now American Society of Radiologic Technologists)
provides practice standards and a code of ethics and is the main professional
society for technologists. ARRT (B) certifies/specialty registers technologists and
sets credentialing requirements; FDA (A) oversees devices/regulation; IAEA (D) is
international and focuses on nuclear/radiation safety.
6. A radiographer’s adherence to the ALARA principle most directly affects which
of the following?
A. The speed at which images are processed in the PACS.
B. The balance between image quality and radiation exposure.
C. The type of film screen used in computed radiography.
D. The billing code used for the exam.
Answer: B
Rationale: ALARA (As Low As Reasonably Achievable) guides minimizing
radiation exposure while ensuring sufficiently high image quality for diagnosis; it’s
directly about tradeoffs between dose and diagnostic quality. It does not relate to
PACS speed (A), film screens (C — outdated tech), or billing (D).
7. A radiographer obtains a portable abdomen radiograph and inadvertently
includes identifying markers incorrectly. Which ethical principle is MOST directly
violated?
A. Veracity.
B. Beneficence.
C. Nonmaleficence.
D. Professionalism/accuracy in documentation.
Answer: D
Rationale: Using correct markers and accurate documentation is part of
professional practice; mislabelling compromises quality and legal/ethical
standards. While veracity (truth) might be indirectly affected (A), the best fit is
