SECTION 1: EMBALMING CHEMISTRY & THEORY (Questions 1-60)
Question 1
When treating blisters, which of the following is NOT accepted as proper
technique?
A) Puncture and drain blisters before embalming
B) Remove loose skin after embalming
C) Observe color change in the affected areas
D) Remove loose integument before embalming
Answer: D) Remove loose integument before embalming
Rationale: The loose integument should be removed after embalming, not before.
Removing it before embalming can lead to additional tissue damage and
compromise the preservation process. The proper sequence involves puncturing
and draining blisters before embalming, observing color changes, and removing
loose skin after embalming is complete.

Question 2
One purpose for which cavity fluids would NOT be recommended is:
,A) Surface packs
B) Arterial injections
C) Visceral treatment
D) Bleaching agents
Answer: B) Arterial injections
Rationale: Cavity fluids are specifically formulated for cavity treatment, surface
packs, and bleaching applications. They are not recommended for arterial
injections because they have different chemical properties, including higher
formaldehyde content and different dye compositions, that make them unsuitable
for vascular infusion.

Question 3
If you use 2 bottles of arterial fluid to make 2½ gallons of a 3-index solution, what
is the index of the concentrated arterial fluid?
A) 30 index
B) 18 index
C) 27 index
D) 36 index
Answer: A) 30 index
,Rationale: The dilution formula is C₁V₁ = C₂V₂. If 2 bottles (assumed to be 1 gallon
total) of concentrated fluid are diluted to 2.5 gallons to achieve a 3-index solution,
then the concentrated index is (2.5 × 3) ÷ 1 = 7.5. However, since 2 bottles are
used, the index per bottle is 30 (15 per bottle × 2). More precisely: (2.5 gallons × 3
index) ÷ (2 bottles × 1 gallon per bottle) = 7.5 ÷ 0.25 = 30 index.

Question 4
A discoloration that appears on the body during life is considered:
A) Ante mortem
B) Post mortem
C) Intravascular
D) Interosseus
Answer: A) Ante mortem
Rationale: Ante mortem discolorations occur during life and are present at the
time of death. These include conditions like jaundice, carbon monoxide poisoning,
and ecchymosis from injuries sustained before death. Post mortem discolorations
develop after death.

Question 5
, Which of the following is a purpose of pre-embalming analysis?
A) To apply appropriate restorative techniques
B) To prescribe and apply proper embalming techniques
C) To aid in proper post-embalming techniques
D) To apply proper service after call
Answer: B) To prescribe and apply proper embalming techniques
Rationale: The pre-embalming analysis is conducted to evaluate the condition of
the body, identify any diseases or conditions that may affect embalming, and
determine the appropriate techniques, chemicals, and procedures needed for
successful preservation and restoration.

A) Yellow
B) Gray
C) Bronze
D) Green
