INTRODUCTION
The National Board Examination (NBE) Science section (FSE 217-0901) is a comprehensive, high-stakes
assessment that evaluates a candidate's mastery of the scientific foundations essential for funeral service
practice. Administered by the International Conference of Funeral Service Examining Boards (ICFSEB), this
rigorous examination is a critical component of licensure for funeral directors and embalmers across the United
States. The NBE Science section comprises approximately 150 scored questions and 20 unscored pretest
questions covering Embalming, Restorative Art, Preparation for Disposition, and Funeral Service Sciences. This
exam demands a deep understanding of embalming chemistry and fluid dynamics, pathology and disease
processes, microbiology and infection control, OSHA regulations and workplace safety, and restorative art
principles. This comprehensive question bank contains 200 advanced, scenario-based questions designed to
simulate the actual NBE Science exam experience. Each question is crafted to test application-level knowledge,
clinical reasoning, and critical thinking skills required for successful funeral service practice. With detailed
rationales explaining both correct and incorrect answers, this resource will prepare you to pass the NBE Science
examination on your first attempt and excel in your funeral service career.
CORE DOMAINS TESTED
1. Embalming (Approx. 62 Questions) – Embalming theory, arterial and cavity treatment, chemical
calculations, fluid dynamics, preservative and accessory chemicals, injection techniques, distribution
and diffusion, and complications management.
2. Restorative Art (Approx. 34 Questions) – Facial and cranial anatomy, features of the face, facial
expression, restorative techniques, modeling compounds, cosmetic application, and post-embalming
treatments.
3. Preparation for Disposition (Approx. 28 Questions) – Preparation of autopsied and traumatized
remains, handling of infectious cases, dressing and casketing procedures, and final preparation
techniques.
4. Funeral Service Sciences (Approx. 26 Questions) – Pathology (disease processes and causes of death),
microbiology (microorganisms and infection control), chemistry (embalming chemistry and reactions),
and anatomy (vascular and skeletal systems).
5. OSHA Regulations & Workplace Safety – OSHA Formaldehyde Standard (29 CFR 1910.1048),
Bloodborne Pathogens Standard (29 CFR 1910.1030), Hazard Communication Standard (29 CFR
1910.1200), personal protective equipment (PPE), and exposure control plans.
6. Microbiology & Infection Control – Pathogenic and saprophytic microorganisms, modes of disease
transmission, disinfection and sterilization, antimicrobial agents, and public health considerations.

QUESTIONS 1-100
Q1: A 72-year-old male decedent with a history of diabetes and
peripheral vascular disease presents for embalming. The embalmer
notes significant edema in the lower extremities and signs of tissue
necrosis. Which of the following pre-embalming treatments is
MOST appropriate for this case?
A) Immediate arterial injection with high-pressure fluid
B) Hypodermic injection of a strong preservative fluid into the
edematous tissues
C) Surface application of a humectant solution
D) Restriction of all fluid injection and reliance on cavity treatment
only
Rationale: The correct answer is B because edematous tissues require
supplemental hypodermic injection to ensure adequate preservation
where arterial fluid may not penetrate effectively due to
compromised circulation. Option A is incorrect because high-pressure
injection can further damage compromised tissues and may cause
additional trauma. Option C is incorrect because surface humectants
address moisture balance but do not provide preservation. Option D
is incorrect because relying solely on cavity treatment would leave
the edematous tissues inadequately preserved.
Q2: Which of the following chemical agents is MOST effective at
inactivating saprophytic bacteria while simultaneously destroying
their nutrient source?
A) Humectants
B) Surfactants
,3
C) Vehicles
D) Dyes
Rationale: The correct answer is B because surfactants reduce surface
tension, allowing the preservative fluid to penetrate tissues more
effectively, which aids in destroying both bacteria and their nutrient
sources. Option A is incorrect because humectants primarily help
maintain moisture balance. Option C is incorrect because vehicles are
solvents used to carry other chemicals. Option D is incorrect because
dyes are used for cosmetic purposes and do not have antimicrobial
properties.
Q3: A embalmer is preparing an arterial solution using a 25-index
fluid. The desired dilution is 1:2 (one part fluid to two parts water).
What is the final index of the solution?
A) 6.25
B) *8.33*
C) 12.5
D) 25
Rationale: The correct answer is B because the final index is
calculated by multiplying the index of the concentrate by the fraction
of concentrate in the total volume. With a 1:2 dilution, the fraction of
concentrate is 1/(1+2)=1/3. 25 × 1/3 = 8.33. Option A is incorrect
because 6.25 would result from a 1:3 dilution. Option C is incorrect
because 12.5 would result from a 1:1 dilution. Option D is incorrect
because 25 is the index of the undiluted concentrate.
Q4: During an embalming procedure, the embalmer observes that
the arterial fluid is not distributing properly to the lower
, 4
extremities. Which of the following is the MOST likely cause of this
issue?
A) Use of an excessively strong fluid concentration
B) Atherosclerosis or advanced arteriosclerosis
C) Improper pH of the injection solution
D) Overly rapid injection rate
Rationale: The correct answer is B because atherosclerosis and
arteriosclerosis narrow and harden the arteries, impeding the flow of
arterial fluid to the extremities. Option A is incorrect because strong
fluid concentration may cause tissue dehydration but does not
directly impede distribution. Option C is incorrect because pH affects
chemical reactions but is not the primary cause of distribution failure.
Option D is incorrect because rapid injection may cause vessel rupture
but does not explain distribution failure.
Q5: Sodium citrate, when used in embalming fluids, functions
primarily as a(n):
A) Anticoagulant
B) Surfactant
C) Humectant
D) Preservative
Rationale: The correct answer is A because sodium citrate is used as
an anticoagulant in embalming fluids to prevent blood from clotting
and to facilitate drainage. Option B is incorrect because surfactants
reduce surface tension. Option C is incorrect because humectants
maintain moisture. Option D is incorrect because preservatives, such
as formaldehyde, are the primary preserving agents.
