RAD 105 MIDTERM EXAM QUESTIONS
WITH COMPLETE SOLUTIONS GRADED
A+
Law of bergonie and tribondeau - Answer- -Cells are more radiosensitive during active
division and when they are primitive in structure and function.
-Cells are more radioresistant if they are more specialized in structure and function and
do not undergo repeated mitosis.
time, distance, shielding - Answer- cardinal rules of radiation protection
absorbtion, transfer than scatter, transmission - Answer- 3 things that can happen to an
x ray beam
die, repair, divide in damaged state - Answer- 3 responses of cells to radiation
early effects of radiation - Answer- 1. bone marrow syndrome (infection, hemmorrhage
anemia)
2. gastrointestinal syndrome (NVD)
3. central nervous system syndrome (seizures, coma, eventual death)
late effects of radiation - Answer- develop over a long time after exposure
1. somatic effects (cataracts, cancer)
2. genetic effects (germ cell damage, possible mutations to offspring)
acute radiation syndrome - Answer- high whole body exposure in a short period of time
threshold dose - Answer- fictional, amount of safe radiation a person can be exposed to
Maslow's Hierarchy of Needs - Answer- physiological, safety, love/belonging,
esteem,need to know/understand, aesthetics, self-actualization
emotional support, emphasis, palpation - Answer- appropriate touching includes
birth-1 - Answer- infant age
1-3 - Answer- toddlers age group
3-5 - Answer- preschoolers
5-10 - Answer- school aged children
, 10-25 - Answer- adolescents

45-65 - Answer- middle aged adults
65+ - Answer- mature adults
base of support - Answer- Foundation on which the body rests
center of gravity - Answer- a hypothetical area of the body where the mass of the body
is concentrated; gravity works from this area
Stability Muscles - Answer- Muscles of the torso
Mobility Muscles - Answer- Extremity muscles
Wilhelm C. Röentgen
November 8, 1895 - Answer- who discovered x ray? when?
ionization - Answer- The process by which a neutral atom gains or loses an electron,
thus requiring a net charge.
radiologist - Answer- The medical physician who specializes in the use of x-rays and
other forms of both ionizing and non-ionizing radiation in the diagnosis and treatment of
disease.
Radiologic Technologist (RT) - Answer- general term applied to an individual who
performs radiography, radiation therapy, or nuclear medicine technology
radiography - Answer- what does the R in RT stand for?
MRI and ultrasound - Answer- the only 2 modalities that use non ionizing radiation
Accreditation - Answer- Voluntary peer review process through which an agency grants
recognition to an institution for a program of study that meets specified criteria.
JCERT (joint review committee on education in radiologic technology) - Answer- who
accredits our rad tech program
Certification - Answer- Voluntary process through which an agency grants recognition to
an individual on demonstration, usually by examination, of specialized professional
skills.
ARRT - Answer- administers RT exam to certify us
