\Q\.a alkaline solution causes decomposition of the formaldehyde. - ANSWERS✔-
Strong
\Q\.a highly acidic solution promotes of the formaldehyde. - ANSWERS✔-
Polymerization
\Q\.a highly solution promotes polymerization of the formaldehyde. - ANSWERS✔-
Acidic
\Q\.adding prolongs shelf life. - ANSWERS✔-Buffers
\Q\.some dyes maybe when exposed to light which causes a color change of the fluid. -
ANSWERS✔-Oxidized
,\Q\.the of embalming fluid refers to the length of time the fluid maintains its
functionality before it is used. - ANSWERS✔-Shelf Life
\Q\.what are 4 factors that affect the shelf life of embalming chemicals? - ANSWERS✔-
Temperature, Time, pH, Light
\Q\. temperatures accelerate polymerization of formaldehyde into paraformaldehyde,
a solid that precipitates out of the solution. This has an overall effect of reducing the index of
the remaining fluid. - ANSWERS✔-Elevated
\Q\.elevated temperatures cause of other disinfectant and preservative components
in the fluid. - ANSWERS✔-Decomposition
\Q\. temperatures cause precipitation of solutes. - ANSWERS✔-Depressed
\Q\.the average shelf life for embalming chemicals is - ___ years. - ANSWERS✔-2, 5
\Q\.this will cause polymerization of many of the components of embalming fluid especially
formaldehyde. - ANSWERS✔-Time
\Q\.on average you shouldn't keep more than a month supply of embalming fluid on hand.
- ANSWERS✔-6
\Q\.this is routinely used as an antipolymerizing agent for formaldehyde. Given enough time it
can be oxidized to formaldehyde which will then turn into paraform. - ANSWERS✔-Methanol
\Q\.this refers to the acidity or alkalinity of the solution. - ANSWERS✔-pH
, \Q\.some dyes maybe oxidized when exposed to which causes a color change of the
fluid. - ANSWERS✔-Light
\Q\. can also increase polymerization of formaldehyde. - ANSWERS✔-Light
\Q\. fluid is the concentrated, preservative embalming chemical that will be diluted with
water or another appropriate vehicle such as alcohol to form the arterial solution also known as
embalming solution or primary dilution for injection into the arterial system during vascular
embalming. - ANSWERS✔-Arterial
\Q\. fluid is an aqueous solution of gasses, liquids, and solids injected into the arterial
system for diffusion into the tissue cells to aid in preservation. - ANSWERS✔-Embalming
\Q\.arterial fluid may be a part of both and injections. - ANSWERS✔-
Primary, Secondary
\Q\.the first initial injection which may or may not contain preservatives. - ANSWERS✔-Primary
\Q\.what is primary injection sometimes referred to as? - ANSWERS✔-Preinjection
\Q\.the injection that takes place after the primary injection. - ANSWERS✔-Secondary
\Q\.the classification of arterial fluid is done in two way which are? - ANSWERS✔-Index, Color
\Q\.the amount of formaldehyde gas in grams dissolved in 100 ml. of solution. - ANSWERS✔-
