,Chapter 01: Introduction to Imaging and Radiologic Sciences
Adler: Introduction to Radiologic and Imaging Sciences and Patient Care, 8TH
Edition
MULTIPLE CHOICE
1. The use of x-rays to create a medical image on patients is referred to as
a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging.
ANSWER: B
Radiography is the making of records of internal structures of the body by passage of x-
rays or gamma rays through the body. These records or images are typically referred to
as radiographs.
REF: p. 4
2. Particular care must be taken when using radiation for medical imaging. This is
the result of radiation’s ability to create in human tissue and possible biochemical
changes.
a. ionizations
b. radio waves
,c. sound waves
d. thermal changes
ANSWER: A
Some forms of electromagnetic energy, including x-rays, have the ability to ionize atoms
in matter. These ionizations have the ability to disrupt the composition of matter and are
capable of disrupting life processes. Special protection should be provided to prevent
excessive exposure to ionizing radiation.
REF: p. 3
3. In the diagnosis of patient disease states, physicians can select from an array of
medical diagnostic modalities. A few of these involve the use of ionizing energy to create
a medical image. If a physician is concerned about the use of ionizing radiation, he or
she may choose to order any of the following diagnostic modalities EXCEPT
a. thermograms.
b. medical sonography.
c. radiography.
d. magnetic resonance imaging.
ANSWER: C
Radiography involves the use of x-rays for the production of medical images. Medical
procedures such as thermograms, sonograms, and magnetic resonance scans use
nonionizing energy forms and consequently do not produce ionizations in human tissue.
They are regarded as nonionizing modalities for imaging and offer excellent alternatives
to physicians concerned about radiation exposure to patients.
REF: pp. 3-4
4. The Greek physician Hippocrates is regarded as the father of Western medicine.
All of the following choices represent his medical beliefs EXCEPT the
, a. use of high ethical standards of conduct.
b. important medical value of sorcery and witchcraft.
c. importance of closely monitoring a patient’s condition and recovery.
d. value of diet and exercise and allowing nature to take its course in recovery.
ANSWER: B
The Hippocratic Corpus is writings that they emphasize rational and natural explanations
for the treatment of disease and reject sorcery and magic. The Hippocratic oath still
governs the ethical conduct of physicians today.
REF: p. 5
5. Throughout the history of medicine, remarkable achievements have been
recorded. These events have led to our current understanding of the human organism
and disease. As this research continues, much of it will most likely focus on
a. proper sanitation and public health.
b. immunology and the development of vaccines.
c. germ theory and infection.
d. human genes and genetic engineering.
ANSWER: D
Although the Human Genome Project is finished, analyses of the data will continue for
many years. The replacement of faulty genes through gene therapy offers promises of
cures for a variety of hereditary diseases, and through genetic engineering, important
pharmaceuticals continue to be developed. Medical research will continue to focus on
the genetic code in all cells.
