Module 5

Question 1

Concentrated, preservative, embalming chemical that is diluted with water to form the arterial solution for injection into the arterial system during vascular embalming. Its purpose is to inactivate saprophytic bacteria and render the body tissues less susceptible to decomposition.

Answer 1

Arterial Fluid

Question 2

Mixture of arterial ( vascular) fluid and water used for the arterial injection. May include supplemental fluids.

Answer 2

Arterial solution

Question 3

Embalming chemical that is injected into a body cavity following aspiration in cavity embalming. Cavity fluid can also be used as the chemical in hypodermic and surface embalming.

Answer 3

Cavity Fluid

Question 4

A fluid the embalmer injects prior to the preservative solution( preinjection fluid) or adds to the preservative solution to enhance certain qualities of the preservative fluid. ( e.g., coinjection, dye, humectant, and water conditioner).

Answer 4

Supplemental Fluid

Question 5

Chemicals used in addition to vascular (arterial) and cavity embalming fluids. Include but are not limited to hardening compounds, preservative powders, sealing agents, mold- preventive agents, and compress application agents.

Answer 5

Accessory Chemicals

Question 6

Fluids designed for use with special body conditions such as jaundice or bodies requiring a high preservative demand as seen in bodies with renal failure, extensive burns, or decomposition.

Answer 6

Special Purpose fluids

Question 7

Formaldehyde is generally available as this, an aqueous solution containing 37% formaldehyde gas by mass in water, or in water and methyl alcohol.

Answer 7

Formalin

Question 8

The precipitate is a solid form of formaldehyde.

Answer 8

Paraformaldehyde

Question 9

Identifies only the absolute formaldehyde gas present in any given product. Refers only to the amount of formaldehyde gas present.

Answer 9

Index

Question 10

pure form liquid at ambient temperature and is used as an embalming and fixative agent. It changes the nature of the proteins, makes them unsuitable as food for bacteria. In addition, used as a disinfecting agent is effective against microorganisms including viruses and spores making it many times more effective as a disinfectant than formaldehyde.

Answer 10

Glutaraldehyde

Question 11

also known as carbolic acid, is classified as a preservative as well as a germicide. Used chiefly in cavity fluid formulations.

Answer 11

Phenol

Question 12

The methyl derivatives of hydantoins. These also liberate formaldehyde at a slow rate.

Answer 12

donor compounds

Question 13

Liquids that serve as a solvent for the numerous ingredients incorporated into embalming fluids

Answer 13

Vehicles

Question 14

Coloring agent, Substances that, on being dissolved, impact a definite color to the embalming solution. They are classified as to their capacity to permanently impart color to the tissues of the body into which they are injected.

Answer 14

Dye

Question 15

Chemical components of vascular fluids that control the rate and degree of tissue firmness by the fluid utilized (e.g; humectants and buffers) ; chemicals for which there may be greatly varying demands predicted on the type of embalming, the environment, and the embalming fluid used.

Answer 15

Modifying agents

Question 16

Embalming chemical that effects the stabilization of acid-base balance within embalming solutions and in embalmed tissues.

Answer 16

Buffers

Question 17

Chemicals taht increase the ability of embalmed tissue to retain moisture.

Answer 17

Humectants

Question 18

Ingredient of embalming fluids that retards the natural postmortem tendency of blood to become more viscous or prevents adverse reactions between blood and other embalming chemicals.

Answer 18

Anti-coagulants

Question 19

surface tension reducer; wetting, penetrating, or surface-active agent. Chemical that reduces the molecular cohesion of a liquid so that it can flow through smaller apertures.

Answer 19

Surfactants

Question 20

Supplemental fluid used primarily to enhance the action of vascular (arterial) solutions.

Answer 20

Co-injection fluids

Question 21

Humectant. Supplemental fluid, used with the regular arterial solution, whose purpose is to retain body moisture and retard dehydration.

Answer 21

Restorative fluids

Question 22

designed to clear the blood vascular system of the blood prior to injection of the preservative solution.

Answer 22

Pre-injection fluid

Question 23

Corrective co-injection chemical reduces tissues swollen with edema.

Answer 23

Edema fluid

Question 24

The mixture of arterial fluid with water and/ or supplemental fluids is called

Answer 24

Primary dilution

Question 25

an embalmer using arterial fluid that has not been diluted with water but rather with supplemental fluids such as coinjection, humectants, and water-corrective fluids.

Answer 25

Waterless embalming

Question 26

in the tissue spaces, the arterial solution is further diluted.

Answer 26

Secondary dilution

Question 27

Passage of solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a semipermeable membrane.

Answer 27

Osmosis

Question 28

Solution having a lesser concentration of dissolved solute than the solution with which it is compared,

Answer 28

Hypotonic

Question 29

Solution having a greater concentration of dissolved solute than the solution with which it is compared.

Answer 29

Hypertonic

Question 30

A solution having a concentration of dissolved solute equal to that of a standard of reference.

Answer 30

Isotonic
