Chapter 11 Key Terms

Question 1

Adverse reaction

Answer 1

undesirable reaction to contrast media that may be harmful to the patient

Question 2

Anaphylactic

Answer 2

manifesting extremely great sensitivity to foreign material

Question 3

High-osmolality contrast media (HOCM)

Answer 3

contrast media that has an osmolality greater than human plasma

Question 4

Hydrophilicity

Answer 4

a tendency of the blood and tissues to absorb fluid

Question 5

Hyperosmolar

Answer 5

a solution that has higher osmotic concentration of particles in solution as compared to blood plasma

Question 6

Hypertonic

Answer 6

the same as hyperosmolar; when a fluid is hypertonic, it will create dehydration

Question 7

Iso-osmolar

Answer 7

having the same osmolality as another fluid; in this case, any contrast that has the same osmolality as human plasma

Question 8

Low-osmolality contrast media (LOCM)

Answer 8

contrast media that has osmolality that is closer to that of human blood plasma

Question 9

Miscibility

Answer 9

capable of being mixed with some other fluid and remaining mixed

Question 10

Osmolality

Answer 10

the concentration of a solution expressed in weight of the molecule in solution

Question 11

Persistence

Answer 11

in terms of contrast media, it means the ability of the contrast to stay in the body

Question 12

Side effect

Answer 12

an unintended reaction to contrast media that is of little or no consequence

Question 13

Tonicity

Answer 13

the osmotic pressure of a solution relative to that of blood

Question 14

Toxicity

Answer 14

the state of being poisonous

Question 15

Viscosity

Answer 15

the resistance of flow (the thickness of a material)
