Why should manipulation of a body exhibiting frozen tissue be kept to a minimum
Because ice crystals that form when tissue freezes will tear the tissue if manipulated
Why is cavity embalming important in cases of renal failure
Because, in addition to edema, there is a buildup of nitrogenous wastes in the tissues, which can neutralize the preservative solution, indicating a high preservative demand

Dry gangrene
What is the main reason rigor mortis should be relieved before embalming begins
During rigor, the proteins of the muscles are "locked" together and it is difficult for the preservative to attach to the proteins. This means there is little absorption of the preservative by the muscles during rigor mortis

What are three body sites where edema can be found
Intracellular - Edema within the individual cells; Intercellular - Edema within the spaces between the cells; Edema within the body cavity
Briefly describe how Epsom salts work on edema
It creates a hypertonic solution which sets up an osmotic gradient that draws the edema from the tissue spaces toward this concentrated salt solution in the capillaries
How is ascites affected by the arterial solution and blood drainage
It is unaffected by arterial fluid and blood drainage because it is located within the cavity around the visceral organs
What is the main purpose behind using a six-pinot injection on a delayed/decomposed embalming

Severe facial edema
Why might an embalmer wait until after embalming is completed to close the mouth of a body in which decomposition is evident
Since the mouth area may swell during embalming, it may be easier to obtain a proper closure after injection (firming is not a problem in these bodies because it is delayed)

In a case of renal failure/jaundice, how is ammonia formed and what is its significance to the embalmer
ammonia, is formed in the gastrointestinal tract by bacterial action and digestive processes. Most ammonia enters the portal circulation and is effectively eliminated by the liver. In liver disease states, minimal removal of ammonia occurs and bypass collateral circulation, in addition to reduced ability for enzymic conversion of ammonia to urea, extremely elevated blood ammonia levels are possible. General alkalemia is the result as blood pH values rise and ammonia readily permeates cells and tissues and causes serious disease consequences with potentially lethal toxicities. The embalming consequence is sky high aldehyde demand and extreme formaldehyde neutralization resulting in poor or failed preservation
List some examples of surface discolorations and when they should be cleaned (and why)
blood, betadine, adhesive tape marks, gentian violet (anti-fungal agent), paint, mercurochrome and tobacco tars- Should be cleaned prior to arterial injection because the pores in the skin are still open and easier to clean. After arterial injection the pores close and it is more difficult to completely clean off discolorations. The embalmer must also see the skin clearly to evaluate if arterial solution is present in a particular location while injecting
Regarding delayed embalming, the main factor that brings about the body's increased fluid need
breakdown of tissues (proteins)
List some examples of extra-vascular blood discolorations
ecchymosis, purpura, petechia, hematoma, post-mortem stain, and Tardieu spots

fluids with an index of 25 or higher
When embalming a case of an aortic aneurysm, what would little or no drainage indicate
loss of embalming solution into the thoracic or abdominal cavity
Describe Tardieu spots
pinpoint hemorrhages seen in areas of advanced livor mortis
List five embalming complications generally encountered in bodies with early signs of decomposition
poor distribution, poor drainage, swelling, increased formaldehyde demand, little to no firming (Fluid distribution is poor because coagula are present in the arterial system; Drainage is poor because blood elements have decomposed; Tissues easily swell because capillaries have broken down or are easily torn by the pressure of the fluid, and tissue structure has been weakened by autolytic and putrefactive changes; Ammonia and nitrogenous products in the tissues greatly increase the preservative demand; Little or no firming is exhibited because of protein breakdown)
What is one of the major problems encountered by the embalmer in preparing a body with diabetes mellitus
poor peripheral circulation - calling for strong arterial solution, a coinjection fluid to increase distribution and diffusion, and dye to indicate distribution
Use of moderate arterial solution in large volume; Slow injection; Use of coinjection; Use of humectant; Use of large amounts of fluid; Intermittent or alternate drainage; Application of massage cream (or other moisture retainer) to exposed skin; Avoid excessive massage of hands, face, and neck; Avoid exposure to air currents
some recommended treatments that will maintain moisture or add moisture to dehydrated bodies.
What should be done if no drainage occurs in a case of an aortic aneurysm
stop the injection and begin a multi-point injection
How can livor mortis be an advantage to the embalmer
the breaking and clearing of livor mortis indicates that fluid has been distributed into those tissues
On a casketed body, what is a good way to detract from eye problems which may have occurred
the use of glasses
What is the significance of nitrogenous products created during the decomposition process
they greatly increase formaldehyde demand
When there has been a delay between death and embalming, describe why a slow rate of flow/slow injection is necessary
to avoid distension or dislodged coagula
Why should the head and shoulders of the dead human body always be elevated
to drain blood from these areas
Describe the theory behind the conversion of yellow jaundice to green jaundice. Include the chemical process and compounds involved
when aldehydes combine with protein or amino acid, it increases the acidity in the local tissues by proton release. The hydrogen ions which produce the acid condition result from the chemical action between aldehyde and protein. The acid medium results in oxidation changes, and the bilirubin is converted to biliverdin.
What are the classic colors of dehydration
yellow, brown and black
