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

a. electrocardiography.
b. radiography.

Radiography is the making of records of internal structures of the body by passage of x-
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
rays or gamma rays through the body. These records or images are typically referred to as ra
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
diographs.

2. Particular care must be taken when using radiation for medical imaging. This is the result of
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
radiation’s ability to create in human tissue and possible biochemical changes.

d. thermal changes l8
ANS: A l8l8
Some forms of electromagnetic energy, including x-
l8 l8 l8 l8 l8 l8
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrupt t
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
he composition of matter and are capable of disrupting life processes. Special protection sh

c. radiography.
d. magnetic resonance imaging. l8 l8

Radiography involves the use of x- l8 l8 l8 l8 l8
rays for the production of medical images. Medical procedures such as thermograms, sonogr
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
ams, and magnetic resonance scans use nonionizing energy forms and consequently do not p
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
roduce ionizations in human tissue. They are regarded as nonionizing modalities for imaging
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8

l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
following choices represent his medical beliefs EXCEPT the
l8 l8 l8 l8 l8 l8 l8
a. use of high ethical standards of conduct.
l8 l8 l8 l8 l8 l8
b. important medical value of sorcery and witchcraft. l8 l8 l8 l8 l8 l8
c. importance of closely monitoring a patient’s condition and recovery. l8 l8 l8 l8 l8 l8 l8 l8
d. value of diet and exercise and allowing nature to take its course in recovery.
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
ANS: B l8l8
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8
the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the
l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l8 l
