MULTIPLE CHOICE k




1. The use of x-rays to create a medical image on patients is referred to as
k k k k k k k k k k k k k k


a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging. k k




ANS: B
Radiography is the making of records of internal structures of the body by k k k k k k k k k k k k


kpassage of x- rays or gamma rays through the body. These records or
k k k k k k k k k k k k


kimages are typically referred t o a s radiographs.

2. Particular care must be taken when using radiation for medical imaging. This is the
k k k k k k k k k k k k k


result of radiation’s ability to create
k k k k k k


in human tissue and possible biochemical changes k k k k k k


.
a. ionizations
b. radio waves k


c. sound waves k


d. thermal changes k




ANS: A
Some forms of electromagnetic energy, including x-
k k k k k k


rays, have the ability to ionize atoms in matter. These ionizations have the ability to
k k k k k k k k k k k k k k


disru pt the composition of matter and are capable of disrupting life
k k k k k k k k k k k k


processes.
k


Special protect k


i on should be provided to prevent excessive exposure to
k k k k k k k k k




k ionizing radiation. REF:p. 3 k k k




3. In the diagnosis of patient disease states, physicians can select from an array of medical
k k k k k k k k k k k k k k


diagnostic modalities. A few of these involve the use of ionizing energy to
k k k k k k k k k k k k k


create a medi cal image. If a physician is concerned about the use of ionizing
k k k k k k k k k k k k k k k


radiation, he or she may choose to order any of the following diagnostic
k k k k k k k k k k k k k


modalities EXCEPT
k k


a. thermograms.
b. medical sonography. k


c. radiography.
d. magnetic resonance imaging. k k




ANS: C
Radiography involves the use of x- k k k k k


rays for the production of medical images. Medical procedures such as thermograms, son
k k k k k k k k k k k k


o grams, and magnetic resonance scans use nonionizing energy forms and consequently d
k k k k k k k k k k k k


o not produce ionizations in human tissue. They are regarded as nonionizing
k k k k k k k k k k k


kmodalities f or i maging and offer excellent alternatives to physicians concerned about
k k k k k k k k k k k k


kradiation expo sure t o patients. k k k k k

4. The Greek physician Hippocrates is regarded as the father of Western medicine. All
k k k k k k k k k k k k


kof t he following choices represent his medical beliefs EXCEPT the
k k k k k k k k k


a. use of high ethical standards of conduct.
k k k k k k


b. important medical value of sorcery and witchcraft. k k k k k k


c. importance of closely monitoring a patient’s condition and recovery. k k k k k k k k


d. value of diet and exercise and allowing nature to take its course in recovery.
k k k k k k k k k k k k k




ANS: B
The Hippocratic Corpus is writings that they emphasize rational and
k k k k k k k k k


natural explanations f or the treatment of disease and reject sorcery and
k k k k k k k k k k k k


magic. The Hippocratic oath still gove
k k r ns the ethical conduct of
k k k k k k k k k


physicians today.

5. Throughout the history of medicine, remarkable achievements have been
k k k k k k k k


krecorded. The s e events have led to our current understanding of the human organism
k k k k k k k k k k k k k k


kand disease. A k s this research continues, much of it will most likely
k k k k k k k k k k k k k


kfocus on k


a. proper sanitation and public health. k k k k


b. immunology and the development of vaccines. k k k k k


c. germ theory and infection. k k k


d. human genes and genetic engineering. k k k k




ANS: D
Although the Human Genome Project is finished, analyses of the data will continue
k k k k k k k k k k k k


for m any years. The replacement of faulty genes through gene therapy
k k k k k k k k k k k k


koffers promises of cure s for a variety of hereditary diseases, and through
k k k k k k k k k k k k


genetic engineering, important pharma ceuticals continue to be developed. Medical
k k k k k k k k k k


kresearch will continue to focus on the gene ti c code in all cells.

6. Wilhelm C. Roentgen’s discovery of ―the x-
k k k k k k


ray‖ is regarded as one of medicine’s most significant achievements. Although his disco
k k k k k k k k k k k k


kvery was accidental, his early research was so thorough that no significant
k k k k k k k k k k k


kfindings have been added to his original theories. This in itself is a true tribute to
k k k k k k k k k k k k k k k


kthe brilliance of Ro entgen as a scientist. One of the most famous early
k k k k k k k k k k k k k


k images he created was an x- k k k k k


ray image of his
k k k


a. colon.
b. laboratory assistant’s foot. k k


c. wife’s hand. k


d. kidneys.
ANS: C
November 8, 1895, is believed by historians to be the day that Roentgen created
k k k k k k k k k k k k k


the famo us image of the hand of his wife. Through his investigative methods, Roentgen
k k k k k k k k k k k k k k k


identified the properties of x-rays.
