ANIMAL TECHNICIAN GRADED A+ - 148 Questions
Section 1: Animal Care and Use Program (Questions 1-14)
1 An institution's Animal Care and Use Program is found to have no written disaster plan. During an external
review, the consulting veterinarian emphasizes that this omission could jeopardize AAALAC accreditation.
Which of the following best explains why a written disaster plan is considered a critical component of a
compliant program?
A) It is required by the Animal Welfare Act regulations specifically for disaster preparedness.
B) It ensures continuity of animal care and human safety during emergencies, demonstrating institutional
commitment to the Guide's performance standards.
C) It is a substitute for having an emergency power generator and backup water supply.
D) It must be approved by the USDA annually to maintain registration.
Answer: B
Rationale: The Guide for the Care and Use of Laboratory Animals (8th edition) identifies disaster planning as an
essential element of the occupational health and safety program and overall animal care program. A written plan
demonstrates proactive risk management and compliance with performance standards, not merely prescriptive
requirements. The Animal Welfare Act does not explicitly mandate a disaster plan, but AAALAC expects one.
Options A, C, and D are incorrect because the AWA does not require a written disaster plan (A), a plan does not
substitute for physical infrastructure (C), and USDA does not approve plans annually (D).
2 A research institution is expanding its animal facility and must decide how to structure the Animal Care and Use
Program to meet federal requirements. Which of the following configurations ensures compliance with the PHS
Policy on Humane Care and Use of Laboratory Animals?
A) The IACUC reports directly to the Principal Investigator of the largest animal use protocol.
B) The Attending Veterinarian has authority over all aspects of animal care and use, including protocol review,
and reports to the Institutional Official.
C) The Institutional Official is a senior administrator who oversees both the IACUC and the Attending
Veterinarian, but the Attending Veterinarian has independent authority over veterinary care.
D) The IACUC chair is appointed by the Attending Veterinarian and serves a renewable term of five years.
Answer: C
Rationale: The PHS Policy requires that the Attending Veterinarian has authority over veterinary care and is a voting
member of the IACUC, but the IACUC reports to the Institutional Official. The Institutional Official is the
individual who signs the Assurance and has ultimate responsibility for the program. Option C correctly separates
the authority of the veterinarian from the administrative oversight of the IO. Option A is wrong because the IACUC
must be independent from principal investigators. Option B incorrectly gives the veterinarian authority over
protocol review, which is the IACUC's role. Option D is incorrect because the IACUC chair is appointed by the
Institutional Official, not the veterinarian.
,3 During a semiannual facility inspection, the IACUC discovers that cages in a rodent room are not labeled with
the required protocol number and species. The institution's Animal Care and Use Program policy states that all
cages must have a label with the protocol number, species, and PI name. Which of the following actions is most
appropriate for the IACUC to take?
A) Issue a programmatic deficiency report and require corrective action within 30 days.
B) Immediately suspend all protocols using that room and notify the USDA.
C) File a report with the Institutional Official and request a complete review of the entire program.
D) Document the finding as a minor noncompliance and request corrective action before the next inspection.
Answer: D
Rationale: Missing cage labels are a minor noncompliance that does not pose an immediate threat to animal welfare.
The IACUC should document the finding and request corrective action, typically before the next inspection. Option
A is too severe for a minor issue; programmatic deficiencies are more systemic. Option B is disproportionate and
unnecessary. Option C is excessive for a single room issue; a full program review is not warranted.
4 An institution's Animal Care and Use Program has been accredited by AAALAC International. Which of the
following statements best describes the relationship between AAALAC accreditation and the institution's
compliance with the Guide for the Care and Use of Laboratory Animals?
A) AAALAC accreditation exempts the institution from adhering to the Guide's standards.
B) AAALAC accreditation is a voluntary process that confirms the program meets or exceeds the Guide's
standards, but does not replace federal regulatory oversight.
C) AAALAC accreditation is required by the PHS Policy for all institutions receiving federal funds.
D) AAALAC accreditation is a one-time event that does not require renewal.
Answer: B
Rationale: AAALAC accreditation is a voluntary, peer-reviewed process that demonstrates a program meets the
standards of the Guide and other applicable regulations. It does not exempt an institution from federal laws (e.g.,
AWA, PHS Policy) and requires regular renewal (typically every three years). Option A is false; accreditation does
not override the Guide. Option C is incorrect because PHS Policy does not mandate AAALAC accreditation,
though it is highly recommended. Option D is false because accreditation is not permanent.
5 A university is developing a new Animal Care and Use Program and must define the role of the Institutional
Official (IO). According to the PHS Policy, which of the following is a primary responsibility of the
Institutional Official?
A) Conducting daily animal husbandry and health checks.
B) Reviewing and approving all animal use protocols before IACUC review.
C) Signing the Animal Welfare Assurance and ensuring institutional compliance with the PHS Policy.
D) Serving as the chair of the IACUC.
Answer: C
Rationale: The Institutional Official is the individual who has the authority to sign the Assurance on behalf of the
institution and is responsible for overall compliance with the PHS Policy. Option A describes veterinary or
husbandry staff. Option B is incorrect because protocol approval is the IACUC's responsibility. Option D is
incorrect; the IO appoints the IACUC chair but does not serve as chair.
6 During a review of the Animal Care and Use Program, it is noted that the program does not include a formal
mechanism for reporting concerns about animal welfare. Which of the following best describes the regulatory
requirement for such a mechanism?
A) The Animal Welfare Act requires a confidential reporting system for animal care concerns.
B) The Guide recommends but does not require a mechanism for reporting concerns.
,C) The PHS Policy mandates that institutions establish a whistleblower policy that protects anonymity and
prohibits retaliation.
D) There is no requirement for a reporting mechanism; the IACUC can investigate concerns informally.
Answer: C
Rationale: The PHS Policy (IV.C.1) requires institutions to establish and maintain a mechanism for reporting
concerns about animal care and use, including provisions for anonymity and protection against retaliation. The
Guide also emphasizes this. Option A is incorrect because the AWA does not explicitly require a reporting system,
though USDA policies do. Option B is wrong because the Guide strongly recommends it. Option D is false; formal
mechanisms are required.
7 An institution's Animal Care and Use Program includes a semiannual program review and facility inspection.
During the review, the IACUC identifies that the program's veterinary care policies do not address the use of
non-pharmaceutical-grade compounds. Which of the following is the most appropriate response?
A) The IACUC should immediately suspend all protocols using non-pharmaceutical-grade compounds.
B) The IACUC should document the deficiency and require the program to develop a policy that justifies the use
of such compounds and ensures they are of the highest quality available.
C) The IACUC should ignore the issue because the Guide does not address non-pharmaceutical-grade
compounds.
D) The IACUC should report the deficiency to the USDA and request a waiver.
Answer: B
Rationale: The Guide (Chapter 3) states that pharmaceutical-grade compounds should be used whenever possible,
but if non-pharmaceutical-grade compounds are necessary, the institution must have a policy that justifies their use
and ensures quality. The IACUC should document the deficiency and require the program to develop such a policy.
Option A is too drastic; suspension is not immediately necessary. Option C is false; the Guide does address this.
Option D is unnecessary; this is not a USDA-reportable deficiency unless it involves significant noncompliance.
8 A research institution is applying for PHS funding and must submit an Animal Welfare Assurance. Which of the
following components is NOT required in the Assurance?
A) A description of the institution's animal care and use program, including the IACUC structure.
B) A list of all animal species and numbers to be used over the next five years.
C) A statement of commitment to comply with the PHS Policy and the Guide.
D) Designation of an Institutional Official and Attending Veterinarian.
Answer: B
Rationale: The PHS Policy requires the Assurance to include a description of the program, a statement of
commitment, and designation of key personnel (IO and AV). However, it does not require a detailed list of species
and numbers for five years; that information is part of individual protocols. Option B is therefore not required in
the Assurance.
9 During an AAALAC site visit, the evaluators note that the institution's Animal Care and Use Program does not
include a formal process for reviewing the qualifications of personnel involved in animal procedures. Which of
the following best explains why this is considered a deficiency?
A) The Animal Welfare Act requires that all personnel be certified by AALAS.
B) The Guide states that the institution must ensure that personnel are qualified and trained, and the IACUC must
verify this as part of protocol approval.
C) The PHS Policy mandates that all personnel have a minimum of five years of experience.
D) AAALAC standards require that all personnel hold a veterinary degree.
Answer: B
, Rationale: The Guide (Chapter 2) and PHS Policy require that the IACUC review the qualifications of personnel as
part of protocol approval. The institution must have a process to ensure that personnel are adequately trained and
qualified. Option A is incorrect; AALAS certification is not mandated by the AWA. Option C is false; no specific
experience requirement exists. Option D is false; not all personnel need a veterinary degree.
10 An institution's Animal Care and Use Program must establish a mechanism for reporting concerns regarding
animal welfare. Which of the following best describes the required elements of such a mechanism under the
PHS Policy and Guide for the Care and Use of Laboratory Animals?
A) A formal, written process that includes multiple reporting pathways (e.g., anonymous, confidential) and
protection against reprisal, with a designated individual responsible for receiving and investigating reports.
B) An informal system that encourages verbal reporting to the attending veterinarian, with no requirement for
written documentation or whistleblower protection.
C) A mandatory reporting line managed by the IACUC chair, with reports required to include the reporter's
identity and a written statement of the concern.
D) A system that allows reporting only through the institutional official, with all reports investigated by an
external third party.
Answer: A
Rationale: The Guide and PHS Policy require a formal, written process for reporting concerns, including multiple
pathways (e.g., anonymous, confidential) and protection against reprisal. Option A correctly captures these
elements. Options B, C, and D lack key components: B omits written documentation and protection; C restricts
anonymity and mandates identity; D limits reporting to one pathway and external investigation.
11 A research institution is expanding its animal care program to include nonhuman primates (NHPs) for the first
time. The IACUC is reviewing the program's compliance with the Guide for the Care and Use of Laboratory
Animals. Which of the following considerations is most critical for the program's approval?
A) Ensuring that the NHP housing area includes environmental enrichment devices that are rotated weekly to
prevent habituation.
B) Demonstrating that the program has established a comprehensive occupational health and safety program that
addresses zoonotic diseases, allergies, and physical hazards specific to NHP handling.
C) Providing evidence that all NHP handlers have completed at least 40 hours of hands-on training prior to
animal arrival.
D) Confirming that the NHP diet includes at least 25% fresh fruits and vegetables to meet nutritional
requirements.
Answer: B
Rationale: The Guide emphasizes that an occupational health and safety program is essential for personnel working
with NHPs due to risks of zoonoses, allergies, and injury. While enrichment (A) and diet (D) are important, they
are secondary to personnel safety. Training hours (C) are not specified as a fixed number in the Guide.
12 During a semiannual IACUC inspection, it is noted that the animal facility's emergency power system has not
been tested in over 18 months. The facility houses rodents, rabbits, and dogs. According to the Guide for the
Care and Use of Laboratory Animals, what is the appropriate corrective action?
A) Document the deficiency and schedule a test within the next 30 days, as the Guide recommends testing at
least annually.
B) Immediately cease all animal activities until the emergency power system is tested and verified operational.
C) No action is required because the Guide only recommends emergency power for facilities with critical
life-support systems, which does not apply to this facility.
D) Submit a plan to the institutional official to install a backup generator within 6 months, as the Guide requires
backup power for all animal facilities.
