Embalming Theory and Practice Exam Verified
Questions, Correct Answers, and Detailed
Explanations for Science Students||Already
Graded A+
1. The primary purpose of arterial embalming is to:
A. Disinfect the body cavity
B. Preserve tissues by chemical action
C. Restore natural color only
D. Dry the tissues
Answer: B
Arterial embalming introduces preservative chemicals through the arterial
system to preserve tissues by chemical action.
2. Which artery is most commonly used for injection in embalming?
A. Femoral artery
B. Axillary artery
C. Brachial artery
D. Common carotid artery
Answer: D
The common carotid artery is most commonly used due to accessibility and
efficient distribution.
3. Which vein is most frequently used for drainage?
A. Femoral vein
B. Jugular vein
C. Subclavian vein
D. Axillary vein
Answer: B
The internal jugular vein allows effective drainage when paired with carotid
injection.
,4. Formaldehyde functions primarily as a:
A. Dehydrating agent
B. Buffer
C. Preservative and disinfectant
D. Coloring agent
Answer: C
Formaldehyde preserves tissues by protein coagulation and destroys
microorganisms.
5. The process by which embalming chemicals diffuse from capillaries into
tissues is called:
A. Osmosis
B. Filtration
C. Diffusion
D. Distribution
Answer: C
Diffusion is the movement of embalming chemicals from higher to lower
concentration within tissues.
6. What is the average formaldehyde concentration of arterial fluid?
A. 5%
B. 10%
C. 20%
D. 37%
Answer: D
Commercial arterial fluids typically contain 37% formaldehyde gas in solution.
7. Which embalming index indicates the percentage of formaldehyde in
solution?
, A. Preservation index
B. Formalin index
C. Embalming index
D. Formaldehyde index
Answer: C
The embalming index expresses grams of formaldehyde per 100 mL of solution.
8. Water hardness primarily affects embalming by:
A. Increasing fluid strength
B. Decreasing preservative action
C. Reacting with embalming chemicals
D. Improving diffusion
Answer: C
Minerals in hard water can react with embalming chemicals, reducing
effectiveness.
9. Which condition would require a higher index arterial fluid?
A. Emaciation
B. Infant case
C. Decomposition
D. Edema
Answer: C
Decomposition requires stronger preservative action to control bacterial
activity.
10. Edema is best treated by using:
A. Hypertonic solutions
B. Hypotonic solutions
C. Isotonic solutions
D. Buffered solutions
Answer: A
Hypertonic solutions draw excess fluid from tissues, reducing edema.
