1. Which of the following best describes the primary purpose of
embalming?
A. To permanently preserve the body indefinitely
B. To temporarily preserve the body and delay decomposition
C. To eliminate all microorganisms from the body
D. To restore life functions
Rationale: Embalming is intended to temporarily preserve the body, slow
decomposition, and provide sanitation and presentation, not to stop
decomposition permanently or restore life.
2. The main chemical used in arterial embalming fluid is:
A. Ethanol
B. Formaldehyde
, C. Acetone
D. Phenol
Rationale: Formaldehyde is the primary active preservative chemical used
in embalming due to its ability to cross-link proteins and inhibit microbial
activity.
3. Rigor mortis is caused primarily by:
A. Bacterial activity
B. ATP depletion in muscle cells
C. Blood clotting
D. Dehydration of tissues
Rationale: Rigor mortis occurs when ATP is depleted, preventing muscle
relaxation and causing stiffness.
4. The ideal pH range for arterial embalming fluid is:
A. 1–2
B. 10–12
C. 3–5
D. 7–8
Rationale: Acidic pH (3–5) enhances protein coagulation and preservation
efficiency of formaldehyde-based fluids.
, 5. The first sign of decomposition is usually:
A. Rigor mortis
B. Green discoloration of the abdomen
C. Bone exposure
D. Skin hardening
Rationale: Green discoloration of the abdomen is due to bacterial action
and hemoglobin breakdown.
6. The purpose of a cavity injection is to:
A. Restore facial features
B. Preserve internal organs and body cavities
C. Increase blood circulation
D. Remove arterial fluid
Rationale: Cavity fluid disinfects and preserves internal organs where
arterial fluid may not reach effectively.
7. Which vessel is most commonly used for arterial embalming?
A. Jugular vein
B. Carotid artery
C. Femoral vein
D. Pulmonary artery
Rationale: The carotid artery is commonly used due to accessibility and
efficient distribution of embalming fluid.
, 8. The term hypostasis refers to:
A. Muscle stiffening
B. Settling of blood due to gravity after death
C. Tissue swelling
D. Gas formation in tissues
Rationale: Hypostasis (lividity) is the pooling of blood in dependent areas
after circulation stops.
9. Embalming fluid strength is measured in:
A. PSI
B. Fahrenheit
C. Index or dilution ratio
D. Millimeters
Rationale: Strength refers to concentration ratios of chemicals in
embalming fluid.
10. The main cause of postmortem dehydration is:
A. Blood loss
B. Infection
C. Evaporation and chemical action of preservatives
D. Temperature increase
Rationale: Formaldehyde-based fluids draw moisture from tissues, causing
dehydration.
