RADT 1010 EXAM 1 QUESTIONS & ANSWERS
Radiography - Answer -the use of x-rays to create radiographs of internal bodily
structures
Radiation - Answer -energy that is transmitted by waves through space or through a
medium (matter)
Energy - Answer -capacity to operate or work
Gamma Rays - Answer -used in nuclear medicine with radioactive substances
When were x-rays discovered? - Answer -November 8,1895
Who discovered x-rays? - Answer -Wilhelm Conrad Roentgen
Radiologic Technology - Answer -the science of the use of x-rays and/or radioactive
substances to diagnose or for a therapeutic purpose in all modalities
Radiography - Answer -the use of x-rays to create radiographs or internal bodily
structures
Radiographer/ Radiologic Technologist - Answer -a registered technologist that
specializes in radiography *technologist not technician*
Radiologist - Answer -a physician/medical doctor who interprets radiographs, performs
fluoroscopic exams and interventional procedures
Certification - Answer -a process through which an agency grants recognition to an
individual on demonstration, usually by examination, of specialized professional skills
Registry - Answer -list of individuals holding certification in a particular profession
Liscensure - Answer -process by which a governmental agency (usually a state) grants
permission to individuals to practice their profession
Infection - Answer -the establishment and growth of a microorganism on or in a host
Microorganism - Answer -pathogen, can do 3 things (mulitply, damage tissue, secrete
exotoxins)
Disease - Answer -if an infection causes injury to the host, resulting in interruption of
the normal structure of function of any part, organ, organ system, the host is said to
have a disease
, Symptoms - Answer -subjective, can't measure
Signs - Answer -objective, can measure
Pathogen - Answer -any disease-producing organism
Types of pathogens - Answer -bacteria, virsuses, fungi, protozoan parasites
What are the 3 things pathogens can do? - Answer -multiply in large numbers causing
an obstruction, cause tissue damage, secrete organic substances called exotoxins
Exotoxin - Answer -toxin that destroys cells or disrupts normal cell metabolism
What are the side effects of exotoxins? - Answer -elevated body temp, nausea,
vomiting, shock
Bacteria - Answer -prokaryotes, no capacity to inject particles or liquid droplets, may
reside in host in the form of a colony
Prokaryotes - Answer -single celled organisms that lack nuclei and membrane-bound
organelles
Bacteria Morphology - Answer -size or shape - 3 types
Cocci - spheres
Bacilli - rods
Spirals
What are some types of bacterial infections - Answer -streptococcal pharyngitis (strep)
Klebsiella pneumonia (bacterial pneumonia)
Clostridium botulinum (food poisoning)
Viruses - Answer -intracellular parasites - must live within a cell (host)
Lack the ability to synthesize proteins
Carry their own genetic information (RNA or DNA not both)
Very very tiny
What is the viral infection process? - Answer --virion attaches to host cell & inserts
genetic information into cell
-the virus uses the metabolic functions of the host cell to produce new viruses
-new viral particles are then released
-sometimes results in destruction of the host or death of the host
What are some types of viral infections? - Answer --rhinovirus (common cold)
-epstein-barr (mononucleosis)
-HIV (human immunodefiency virus)
-HBV (hepatitus B)
