Practice Questions And Correct Answers
(Verified Ans
1. Which arterial fluid component primarily acts as a buffer to maintain a slightly
alkaline pH, thereby preventing acid-driven protein coagulation during injection?
A. Formaldehyde
B. Sodium borate
C. Methanol
D. Phenol
Answer: B. Sodium borate
Rationale: Sodium borate (borax) is a buffering agent that neutralizes acids and maintains
pH near 7.5-8.0, optimizing formaldehyde's cross-linking with proteins. Formaldehyde is
the active preservative, methanol is a stabilizer, and phenol is a germicide-none primarily
buffer.
2. A decedent with a known history of active pulmonary tuberculosis requires
embalming. Which control measure is mandated by Cal/OSHA to mitigate aerosolized
transmission risk during cavity treatment?
A. N95 respirator and eye protection
B. Surgical mask and gloves only
C. Powered air-purifying respirator (PAPR) with HEPA filter
D. Face shield and gown without respiratory protection
Answer: C. Powered air-purifying respirator (PAPR) with HEPA filter
Rationale: Cal/OSHA mandates a PAPR with HEPA filter for aerosol-generating
procedures on known or suspected TB cases, as N95 may not provide adequate protection
during cavity aspiration. Surgical masks and face shields alone are insufficient for
airborne precautions.

,3. During embalming of a jaundiced decedent, the use of a high-index arterial fluid
without adequate drainage may result in which post-embalming artifact?
A. Greenish discoloration of the sclera
B. Excessive tissue dehydration and wrinkling
C. Grayish-brown discoloration due to biliverdin conversion
D. Pinkish-red flush from formaldehyde-induced methemoglobin
Answer: C. Grayish-brown discoloration due to biliverdin conversion
Rationale: High-index formaldehyde can oxidize bilirubin to biliverdin, producing a
grayish-brown hue, especially if drainage is poor and fluid remains in tissues. Dehydration
(B) occurs with strong astringents, while pink flush (D) is from formaldehyde reacting with
hemoglobin, not bilirubin.
4. Which California statute governs the required waiting period before cremation
when no autopsy is performed?
A. Health and Safety Code § 7050
B. Business and Professions Code § 7600
C. Health and Safety Code § 7051.5
D. Penal Code § 274
Answer: C. Health and Safety Code § 7051.5
Rationale: Health and Safety Code § 7051.5 mandates a 24-hour waiting period after death
before cremation if no autopsy is required. § 7050 covers general disposition, § 7600 is
licensing, and Penal Code § 274 addresses illegal disposal.

,5. In restorative art, the 'rule of fifth' is applied to determine which facial proportion?
A. Width of the mouth relative to interpupillary distance
B. Vertical distance from hairline to eyebrows
C. Width of the nose compared to the intercanthal distance
D. Height of the ears relative to the brow line
Answer: C. Width of the nose compared to the intercanthal distance
Rationale: The rule of fifth divides facial width into five equal parts; the central fifth
approximates nose width, which should equal intercanthal distance. Other options refer to
different canons (e.g., rule of thirds for vertical proportions).
6. A body donated to science is later claimed by family for embalming and burial.
Under California law, which entity has priority for disposition if the family disputes
the donation?
A. The anatomical gift recipient
B. The surviving spouse
C. The eldest child
D. The county coroner
Answer: A. The anatomical gift recipient
Rationale: Under the Uniform Anatomical Gift Act as adopted in California, a valid
donation gives priority to the recipient for the specified purpose. Family cannot override a
legal donation unless fraud or misrepresentation is proven.

, 7. When embalming a body with extensive edema, which pre-injection technique is
most effective to reduce swelling and improve fluid distribution?
A. Multiple-site injection with restricted drainage
B. Use of a high-index cavity fluid as pre-injection
C. Surface application of a hypertonic solution
D. Injection of a sclerosing agent via the femoral artery
Answer: A. Multiple-site injection with restricted drainage
Rationale: Multiple-site injection with restricted drainage allows for better fluid
distribution and reduces edema by limiting fluid accumulation. Cavity fluid is for cavities,
hypertonic surface applications are ineffective for systemic edema, and sclerosing agents
are not standard embalming practice.
8. Which embalming instrument is specifically designed to remove blood clots and
debris from the vascular system during injection?
A. Aneurysm needle
B. Arterial tube
C. Drain tube
D. Separator
Answer: D. Separator
Rationale: A separator (or clot extractor) is used to break up and remove clots. Arterial
and drain tubes are for injection and drainage, and an aneurysm needle is for ligating
vessels.
