BMS Bachelor of Mortuary Science Embalming and Mortuary Chemistry Questions and Answers Flashcards

What is the primary purpose of a pre-injection fluid in the embalming process?

Answer: To condition the vascular system and reduce clotting before arterial injection

Pre-injection fluids contain anticoagulants and surfactants that condition blood vessels, break down clots, and prepare the vascular system for better distribution of the arterial solution.

Which type of embalming fluid would be most appropriate for a body exhibiting signs of jaundice?

Answer: A non-formaldehyde or low-index fluid with active dye

Jaundiced remains benefit from a low-index or non-formaldehyde fluid with active dye to counteract yellow discoloration, since high-index fluids can intensify the jaundice coloring.

What does the term 'index' refer to when describing embalming fluid strength?

Answer: The percentage of formaldehyde in the concentrated fluid

The index of an embalming fluid indicates the percentage of formaldehyde gas dissolved in the concentrated solution before dilution.

During cavity embalming, which chemical is the primary active ingredient in most cavity fluids?

Answer: Formaldehyde at a higher concentration than arterial fluid

Cavity fluids contain formaldehyde at significantly higher concentrations than arterial fluids to ensure thorough preservation of the visceral organs.

What is the effect of rigor mortis on the embalming process?

Answer: It restricts fluid distribution due to muscle stiffness

Rigor mortis causes muscle stiffness that can impede the flow and distribution of embalming fluid, often requiring massage or manipulation to achieve adequate penetration.

Which modifying agent is added to embalming fluid to counteract the effects of edema in tissues?

Answer: A desiccant or dehydrating agent such as aluminum sulfate

Dehydrating agents like aluminum sulfate help draw excess moisture from edematous tissues, firming them and improving the cosmetic result.
