NVCC RAD 105 FINAL REVIEW
EXAM QUESTIONS WITH
CORRECT DETAILED ANSWERS
Bremsstrahlung radiation - Answer-occurs when high speed e- passes near nucleus of
an atom
Characteristic radiation - Answer-occurs when an incident e- ejects an orbital e- from an
inner shell of an atom in the bombarded material
General Radiographic Unit - Answer-generates timed exposure of x-radiation to produce
static radiographic image images of the human body
Fluoroscopic Unit - Answer-produces a steady flow of low intensity x-rays used by the
radiologist to view "real time" images of the human body form and function
Digital Imaging - Answer-replacing darkroom film processing systems, it provides a
computerized imaging system that permits LCD screen viewing, eliminates cassettes;
eliminates x-ray film; post-acquisition image enhancement; filmless image archives
portable radiography and fluoroscopy - Answer-mobile units designed to operate at
bedside when a patient cannot be moved
Computed Tomography - Answer-a rotating x-ray tube connected to a computerized
imaging system that produces cross sectional images of the human body
Magnetic resonance imaging - Answer-and extremely powerful pulsating electromagnet
connected to a computerized imaging system that produces cross sectional images of
soft tissue structures
nuclear medicine - Answer-uses a radiation detector to track and image radioactive
pharmaceuticals in the human body
Positron Emission Tomography - Answer-a radioactive drug is injected into the body a
computerized imaging system then produces cross sectional images indicating the
function of an organ
sonography - Answer-uses high frequency sound waves to obtain echo images of
internal organs and body structures
, Picture Archiving and Communication System - Answer-a computer system and data
base that stores radiographic images in a digital format along with all other patient
information and medical records
ethics - Answer-focus on moral questions and guidelines rather than answers and rules
in past - Answer-codes were extremely restrictive and told practitioners what they could
and could not do
today - Answer-codes focus on the ideals for practice in a profession
whistleblowing - Answer-ethically three questions need to be answered; how serious is
the unethical or illegal behavior? what is the strength of the evidence? what are the
normal channels for resolving the issue? have they been attempted?
respondeat superior - Answer-"let the master answer"; the employer pays the victim for
the torts committed by its employees
res ipsa loquitor - Answer-defendant is responsible to prove innocence because "the
thing that speaks for itself"; case built around evidence that an injury could not have
occurred if there had been no negligence
autonomy - Answer-from greek auto-nomos meaning one who gives oneself their own
law; each person is entitled to determine their own destiny; basic right to self
determination including the right to make informed decisions concerning their own body
nonmaleficence - Answer-founded in ethical people "to do no harm"; does not require
individual to perform any additional action but merely asks that the person not harm
another
beneficence - Answer-remove and prevent evil and harm; do and promote good;
requires individual to perform some action either to prevent harm or to do good; may
require health professional to take a stand against another or to intercede for the
patient's well-being
justice - Answer-requires that individuals be treated according to what is due, fair and/or
vowed; "equal distribution of benefits" or impartiality
civil assault - Answer-can be filed if patient is apprehensive of injury by the imprudent
conduct of the radiographer
civil battery - Answer-actual bodily harm has been inflicted on a patient as a result of
intentional physical contact between a health care provider and a patient
negligence - Answer-unintentional misconduct; breach is a failure to fulfill expected
standards of care
