RTE 1000 - Unit 2 - Contrast Mediaatomic number - ANS-the number of protons in the nucleus of an atom
BUN - ANS-blood urea nitrogen; a blood test to determine urea levels in the body (high
levels indicate compromised kidney function)
bronchospasm - ANS-involuntary constriction of the bronchial tubes usually resulting
form an immune system reaction to a foreign particle or molecule.
contraindication - ANS-factors of a patient's history or present status that indicate that
medical procedure should not be performed or that medication should not be given.
creatinine - ANS-nitrogen-containing waste products of metabolism excreted by the
kidney's filtration system. High levels indicate poor filtration by the kidneys.
extravasation - ANS-leakage from a vessel into the tissue.
histamine - ANS-molecular substance containing an amine group; causes bronchial
constriction and a decrease in blood pressure.
ion - ANS-atom or molecule having a negative charge or a positive charge.
osmolality - ANS-measurement of the number of particles that can crowd out water
molecules in a measured mass of water.
osmosis - ANS-movement of water from an area of high concentration to an area of low
concentration.
pH - ANS-relative acidity or basicity of a solution. Below 7.0 is considered acidic and
above 7.0 is alkaline.
radiopharmaceutical - ANS-pharmaceutical compound that is attached to a
radioisotope.
shock - ANS-inadequate blood flow within the body with resulting loss of oxygen and
therefore energy.
, solution - ANS-uniform mixture of two or more substances composed of molecule-sized
particles that do not react together chemically.
suspension - ANS-non-uniform mixture of two or more substances, one of which is
composed of larger-than-molecule-size particles that have a tendency to cluster
together.
radiolucent contrast - ANS-Negative; X-ray photons are easily transmitted through
radiolucent contrast media. Will show up as areas of black on a radiograph or during
fluoroscopy.
radiopaque contrast - ANS-Positive; x-ray photons are absorbed by radiopaque contrast
media because these media are opaque to x-rays. These will appear white on
radiographs or during fluoroscopy.
negative contrast media properties - ANS-composed of low atomic number elements
and are administered as gas (air) or gas-producing tablets, crystals ("fizzies"), or soda
water.
when would negative contrast media be used? - ANS-double contrast studies, UGI and
barium enema with air
are adverse reactions and complications during negative contrast media minimal, yes or
no? - ANS-yes
physical properties of positive contrast media - ANS-barium has an atomic number of 56
(thus making it radiopaque); barium sulfate is an inert powder composed of crystals that
are used for examination of the digestive tract.
barium is water soluble, true or false? - ANS-false; barium is not soluble in water and it
must be shaken into a suspension.
when would you use positive contrast media? - ANS-esophagram, UGI and barium
enema (with and without air)
four consistencies of barium sulfate are...? - ANS-thick, thin, pre-mixed and tablets
patient prep for contrast studies - UGI - ANS-NPO (nothing by mouth) after midnight the
day before the study.
