Translate PDF. The use of x-rays to create a medical image on patients is referred to as a. ANS: 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. Particular care must be taken when using radiation for medical imaging.
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. 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.
ANS: 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. The Greek physician Hippocrates is regarded as the father of Western medicine. ANS: 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.
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. 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.
Wilhelm C. Although his discovery was accidental, his early research was so thorough that no significant findings have been added to his original theories.
