Patient Care: 200 Questions &
Answers with Rationales – 8th Edition
Exam Review
Unit 1: The Profession of Radiologic and Imaging Sciences

1. A physician who specializes in the interpretation of medical images
is known as a:

 A) Radiographer
 B) Radiologist
 C) Radiologic Technologist
 D) Radiologist Assistant

Answer: B) Radiologist

Rationale: A radiologist is a physician who has completed medical school
and specialized training in interpreting diagnostic medical images.
Radiographers and radiologic technologists are the professionals who
perform the imaging examinations, while radiologist assistants are
advanced-level technologists who work under radiologist supervision.




2. Which imaging modality uses no ionizing radiation and utilizes radio
waves and magnetic fields?

,  A) Nuclear imaging
 B) Thermography
 C) Computed tomography
 D) MRI

Answer: D) MRI

Rationale: Magnetic resonance imaging (MRI) uses a strong magnetic field
and radio waves along with a computer to generate sectional images. MRI
creates no ionizations at current energy levels and is considered safe,
particularly for pediatric and pregnant patients. Nuclear imaging and CT
both use ionizing radiation.




3. To become a board-certified radiologist, the traditional educational
sequence after high school is:

 A) Residency, baccalaureate degree, medical school
 B) Residency, medical school, baccalaureate degree
 C) Baccalaureate degree, residency, medical school
 D) Baccalaureate degree, medical school, residency

Answer: D) Baccalaureate degree, medical school, residency

Rationale: Students must first complete a 4-year premed baccalaureate
degree, then attend medical school, followed by a residency in radiology
(typically 3-4 years). Some radiologists continue with additional
specialization through fellowships.

,4. The radiography "practice standards" are developed and maintained
by which organization?

 A) American Medical Association (AMA)
 B) American Society of Radiologic Technologists (ASRT)
 C) American Registry of Radiologic Technologists (ARRT)
 D) Food and Drug Administration (FDA)

Answer: B) American Society of Radiologic Technologists (ASRT)

Rationale: Clinical practice standards for radiography are developed by the
ASRT. These practice standards define the role of the radiographer and
establish criteria used to judge professional performance. The ARRT
administers certification examinations, while the AMA represents
physicians.




5. Which professional organization is responsible for administering the
certification examination for radiologic technologists?

 A) ASRT
 B) ARRT
 C) JRCERT
 D) RSNA

Answer: B) ARRT

Rationale: The American Registry of Radiologic Technologists (ARRT) is the
certifying body that administers the national certification examination. The
ASRT is the professional society, JRCERT accredits educational programs,
and RSNA is a radiology society for physicians.

, 6. Which of the following is NOT directly involved with and
responsible for a student radiographer's education?

 A) Program director
 B) Clinical coordinator
 C) Medical equipment applications specialist
 D) Didactic faculty member

Answer: C) Medical equipment applications specialist

Rationale: Applications specialists from medical imaging companies teach
users how to operate specific products but are not responsible for the
fundamental education of radiography students. Program directors, clinical
instructors, and didactic faculty have direct responsibility for teaching the
principles of radiography.




7. What is the minimum degree typically required to become a
registered radiologic technologist?

 A) Certificate
 B) Associate degree
 C) Bachelor's degree
 D) Master's degree

Answer: B) Associate degree

Rationale: Most entry-level radiologic technologists complete an associate
degree program accredited by JRCERT. While bachelor's degree programs
