ANS: B b h b h



Radiography is the making of records of internal structures of the body b h b h b h b h b h b h b h b h b h b h b h



by passage of x-rays or gamma rays through the body. These records or images are
b h b h bh bh bh bh bh bh bh bh bh bh bh bh bh



typically referred to as radiographs.

2. Particular care must be taken when using radiation for medical imaging.
b h b h b h b h b h b h b h b h b h b h



This is the result of radiation’s ability to create
b h b h in human tissue
b h bh b h b h b h b h b h b h b h b h b h b h



and possible biochemical changes.
b h b h b h bh



a. ionizations
b. radio waves b h



c. sound waves b h



d. thermal changes b h




ANS: A
Some forms of electromagnetic energy, including x-rays, have the ability to
b h b h b h b h b h b h b h b h b h b h



ionize atoms in matter. These ionizations have the ability to disrupt the
b h bh b h b h b h b h b h b h b h b h b h b h



composition of matter and are capable of disrupting life processes.
b h b h b h b h b h b h b h b h b h b h



Special protection should be provided to prevent excessive exposure to
b h b h b h b h b h b h b h b h b h b h



ionizing radiation.

REF: p. b h 3

3. In the diagnosis of patient disease states, physicians can select from an
b h b h b h b h b h b h b h b h b h b h b h



array of medical diagnostic modalities. A few of these involve the use
b h b h b h b h b h b h bh b h b h b h b h b h



of ionizing energy to create a medical image. If a physician is
b h b h b h b h b h b h b h b h b h b h b h b h



concerned about the use of ionizing radiation, he or she may choose to
b h b h b h b h b h b h bh b h b h b h b h b h b h



order any of the following diagnostic modalities EXCEPT
b h b h b h b h b h b h b h b h



a. thermograms.
b. medical sonography. b h



c. radiography.
d. magnetic resonance imaging. b h b h




ANS: C
Radiography involves the use of x-rays for the production of medical b h b h b h b h b h b h b h b h b h b h



images. Medical procedures such as thermograms, sonograms, and
b h b h b h b h b h b h b h b h



magnetic resonance scans use nonionizing energy forms and
b h b h b h bh b h b h b h b h



consequently do not produce ionizations in human tissue. They are
b h b h b h b h b h b h bh b h b h b h



regarded as nonionizing modalities for imaging and offer excellent
b h b h b h b h b h b h b h b h bh



alternatives to physicians concerned about radiation exposure to patients.

4. The Greek physician Hippocrates is regarded as the father of Western
b h b h b h b h b h b h b h b h b h b h



medicine. All of the following choices represent his medical beliefs
b h bh bh b h b h b h b h b h b h b h



EXCEPT the
b h b h



a. use of high ethical standards of conduct.
b h b h b h b h b h b h



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



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



d. value of diet and exercise and allowing nature to take its course in
b h b h b h b h b h b h b h b h b h b h b h b h



recovery.
b h




ANS: B
The Hippocratic Corpus is writings that they emphasize rational and natural
b h b h b h b h b h b h b h b h b h b h



explanations for the treatment of disease and reject sorcery and magic. The
bh b h b h b h b h b h b h b h b h b h b h b h



Hippocratic oath still governs the ethical conduct of physicians today.

ANS: D
Although the Human Genome Project is finished, analyses of the data will
b h b h b h b h b h b h b h b h b h b h b h



continue for many years. The replacement of faulty genes through gene
b h b h b h b h b h b h b h b h b h b h b h



therapy offers promises of cures for a variety of hereditary diseases, and
b h b h bh b h b h b h b h b h b h b h b h b h



through genetic engineering, important pharmaceuticals continue to be

6. Wilhelm C. Roentgen’s discovery of ―the x-ray‖ is regarded as one of
b h b h b h b h b h b h b h b h b h b h b h



medicine’s most significant achievements. Although his discovery was
b h bh b h b h bh b h b h b h



accidental, his early research was so thorough that no significant findings
b h b h b h bh b h b h b h b h b h b h b h



have been added to his original theories. This in itself is a true tribute
b h b h b h b h b h b h b h b h b h b h b h b h b h b h



to the brilliance of Roentgen as a scientist. One of the most famous
b h b h b h b h b h b h b h bh b h b h b h b h b h



early images he created was an x-ray image of his
b h b h b h b h b h b h b h b h b h b h



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



c. wife’s hand. b h



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



created the famous image of the hand of his wife. Through his
b h b h bh b h b h b h b h b h b h b h b h b h



b investigative methods, Roentgen identified the properties of x-rays.

, 7. A bh valuable x-ray procedure used to diagnose a myocardial infarction is
b h b h b h b h b h b h b h b h b h



a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography. b h




ANS: D
Coronary arteriography is an extremely valuable tool in diagnosing
b h b h b h b h b h b h b h b h



atherosclerosis, which can block the coronary arteries and cause a heart
b h bh b h b h b h b h b h b h b h b h b h



attack (myocardial infarction). By way of a special catheter with a
b h b h bh b h b h b h b h b h b h b h b h



balloon tip, effective treatment of atherosclerosis is possible. This
b h b h b h b h b h b h b h b h b h



treatment of a blocked blood vessel is termed angioplasty. Angioplasty is
b h b h b h b h b h b h b h b h b h b h b h



used to treat patients without having to use invasive open-heart surgery.

8. All of the following are true of the diagnostic procedure of mammography
b h b h b h b h b h b h b h b h b h b h b h



EXCEPT
b h



a. it is very valuable for the detection of early breast cancers.
b h b h b h b h b h b h b h b h b h b h



b. the procedures may be performed using a general radiographic machine.
b h b h b h b h b h b h b h b h b h



c. radiographers need to be specially trained in order to perform b h b h b h b h b h b h b h b h b h



mammography.
b h



d. radiographers must be certified by the ARRT to qualify b h b h b h b h b h bh b h b h



for the mammography examination.
b h b h bh b h




ANS: B
Special breast imaging centers have been built to accommodate the demand
b h b h b h b h b h b h b h b h b h b h



for mammography procedures. Equipment and supplies, such as a specially
b h b h b h b h b h b h b h b h b h b h



designed x-ray tube and high-resolution digital imaging detectors, are used to
b h b h bh b h b h b h b h b h b h b h b h



create high-quality breast images. Mammography cannot be performed
b h b h b h b h b h b h b h b h



using general x-ray equipment.

9. To study the blood vessels of the brain, kidneys, liver, and other
b h b h b h b h b h b h b h b h b h b h b h



organs, contrast material is administered into these vessels by using
b h b h bh b h b h b h b h b h b h b h



a. catheters.
b. stents.
c. balloons.
d. none of the above. b h b h b h




ANS: A
Angiography is the term for radiologic examination of the blood vessels
b h b h b h b h b h b h b h b h b h b h



after injection of a contrast medium. Most often, the contrast material
b h b h b h b h b h b h b h b h b h b h b h



is injected through a catheter, which can be directed to a variety of
b h b h b h b h b h b h b h b h b h b h b h b h b h



major arteries or veins for visualization of these structures.
