Introduction
This comprehensive practice examination is designed to assess the
candidate's knowledge, clinical reasoning, and decision-making skills
essential for the Associate – Infection Prevention and Control (a-IPC™)
certification exam administered by the Certification Board of Infection
Control and Epidemiology, Inc. (CBIC®). The exam covers foundational
principles of infection prevention and control, including identification of
infectious diseases, surveillance and epidemiologic investigation,
,transmission prevention, sterilization and disinfection, and program
management and communication. Through 100 multiple-choice questions
and detailed rationales, this assessment evaluates the candidate's ability to
apply theoretical knowledge to real-world infection prevention scenarios,
ensuring they are prepared for the demands of the a-IPC certification
exam. The content aligns with the CBIC a-IPC™ 2025 Content Outline
effective May 22, 2026, and reflects the 2026/2027 exam blueprint.
Section One: Questions 1–100
Question 1
The bacterium most likely to be transmitted from mother to infant during
labor and cause neonatal sepsis is:
A. Escherichia coli
B. Staphylococcus aureus
C. Group B Streptococcus (GBS)
D. Group A Streptococcus
C. Group B Streptococcus (GBS)
RATIONALE: In Group B Streptococcus (GBS) neonatal infections,
heavy maternal colonization is associated with an increased risk for
preterm labor and neonatal infection. Intrauterine infection occurs via
ascending spread of GBS from the vagina of a colonized pregnant
woman.
Question 2
Which of the following is an example of the criterion of "Strength of the
Association" from Hill's Criteria for Causation?
A. In a study of the association between antibiotic exposure and
development of C. difficile infection, the odds ratio was 2.3
B. The authors' conclusions are consistent with those of three other
studies
C. Antibiotic therapy began an average of 3 weeks before C. difficile
infection developed
,D. Prolonged antibiotic therapy was a greater risk factor than short-term
therapy
A. In a study of the association between antibiotic exposure and
development of C. difficile infection, the odds ratio was 2.3
RATIONALE: Strength of Association is the first criterion: the
incidence of disease should be higher in those exposed to the factor.
The odds ratio is a statistical measure indicating how strongly a risk
factor is associated with a disease outcome.
Question 3
Which organism requires the use of soap and water rather than alcohol-
based hand rub for hand hygiene due to spore formation?
A. Staphylococcus aureus
B. Clostridioides difficile
C. Pseudomonas aeruginosa
D. Escherichia coli
B. Clostridioides difficile
RATIONALE: C. difficile forms spores that are resistant to alcohol-
based hand rubs. Soap and water must be used for hand hygiene when
caring for patients with C. difficile infection to physically remove spores.
Question 4
Which of the following is the MOST effective method for reducing
healthcare-associated infections (HAIs)?
A. Routine environmental disinfection
B. Hand hygiene compliance
C. Antimicrobial stewardship programs
D. Active surveillance cultures
B. Hand hygiene compliance
RATIONALE: Hand hygiene is the single most effective intervention
for reducing healthcare-associated infections. Consistent compliance
, with hand hygiene protocols significantly reduces transmission of
pathogens in healthcare settings.
Question 5
What is the primary purpose of surveillance in infection prevention and
control?
A. To identify all infections in a healthcare facility
B. To monitor infection rates, detect outbreaks, and guide prevention
efforts
C. To enforce hand hygiene compliance
D. To collect data for regulatory reporting only
B. To monitor infection rates, detect outbreaks, and guide prevention
efforts
RATIONALE: Surveillance is the ongoing, systematic collection,
analysis, and interpretation of health data essential to planning,
implementation, and evaluation of infection prevention practices.
Question 6
A patient is diagnosed with a surgical site infection (SSI) 10 days post-
operatively. This is classified as:
A. Superficial incisional SSI
B. Deep incisional SSI
C. Organ/space SSI
D. Cannot be determined from the information provided
D. Cannot be determined from the information provided
RATIONALE: Surgical site infections are classified based on the
depth and location of the infection. Without knowing whether the
infection involves the skin/subcutaneous tissue, deep fascia/muscle, or
organ/space, the classification cannot be determined.
