Embalming Techniques & Protocols Flashcards

According to OSHA standards, which personal protective equipment (PPE) is mandatory during arterial embalming procedures?

Answer: Gloves, gown, face shield, and waterproof apron

OSHA's Bloodborne Pathogen Standard requires gloves, protective gown, face shield or mask with eye protection, and fluid-resistant apron during embalming to protect against exposure to blood and chemicals.

What is the role of a modifying fluid (co-injection) used alongside primary arterial fluid?

Answer: It supplements the primary fluid by addressing specific tissue conditions the preservative alone cannot correct

Co-injection fluids (modifying fluids) work alongside arterial preservative to condition blood, dilate vessels, control pH, add moisture, or counteract specific conditions such as jaundice or edema.

Which of the following is a sign that arterial embalming fluid has NOT reached the facial tissues adequately?

Answer: Sunken, pale, or discolored areas on the face with no resistance to palpation

Pale, sunken, or soft facial tissue after arterial injection indicates inadequate fluid distribution, requiring supplemental hypodermic or surface treatment.

What is the correct sequence of steps when performing cavity embalming?

Answer: Aspirate thoroughly, then inject cavity fluid and re-aspirate after 6–8 hours if needed

Proper cavity embalming requires first aspirating gases and liquids with the trocar, then injecting cavity fluid; re-aspiration and re-injection may be performed 6–8 hours later if purge occurs.

Which chemical reaction occurs when formaldehyde contacts proteins in body tissue during embalming?

Answer: Cross-linking of protein chains (fixation)

Formaldehyde fixes tissue by forming methylene bridges (cross-links) between protein molecules, making them resistant to decomposition by bacterial enzymes.

When is it appropriate to use a higher injection pressure during arterial embalming?

Answer: When clots, arteriosclerosis, or vessel resistance impede fluid flow

Increased pressure may be necessary to force fluid past obstructions such as thrombi or calcified arteries, though it must be balanced against the risk of tissue distension.

A body shows signs of purge at the mouth or nose during embalming. What is the FIRST action the embalmer should take?

Answer: Position the body with head elevated, aspirate purge material, and pack the throat as needed

Purge should be controlled by elevating the head, aspirating expelled material with a nasal tube or trocar, and packing the throat to prevent further seepage while embalming continues.
