This examination assesses knowledge required for the Associate - Infection Prevention and Control (A-IPC) credential, including
infectious disease processes, surveillance, transmission-based precautions, occupational health, and environment of care.
Select the single best answer. Passing score is 80%.
SECTION 1: Infectious Disease Processes and Pathogens
Q1
A patient develops watery diarrhea 8 days after admission. Stool testing is positive for Clostridioides difficile toxin. The
infection preventionist is asked whether this event meets the definition of a healthcare-associated infection. Which criterion is
most relevant?
A. Any positive C. difficile test is always community-onset
B. Onset of symptoms and positive laboratory test on or after hospital day 4 typically meets criteria for healthcare-facility onset C.
difficile infection
C. Only cases diagnosed after discharge are healthcare-associated
D. C. difficile is never considered healthcare-associated
Correct Answer: B
Rationale:
NHSN and standard surveillance definitions classify C. difficile with onset on or after day 4 of hospitalization as healthcare-facility onset,
provided laboratory evidence supports the diagnosis.
Q2
An outbreak of surgical-site infections is linked to a particular operating room. Cultures from an anesthesia machine grow the
same organism recovered from patients. Which characteristic of the organism would most support its role as an environmental
pathogen capable of prolonged survival?
A. Strict anaerobic metabolism only
B. Ability to form biofilms on moist surfaces and resist desiccation
C. Immediate inactivation by room air
D. Requirement for continuous human carriage to persist
Correct Answer: B
Rationale:
Organisms that form biofilms and tolerate dry or moist environmental conditions can persist on equipment and serve as reservoirs for
transmission.
Q3
A nurse asks why hand hygiene is required even when gloves are worn for contact with a patient on Contact Precautions.
Which explanation is most accurate?
A. Gloves replace the need for hand hygiene in all situations
B. Gloves can become contaminated during removal or have micro-perforations; hand hygiene after glove removal reduces residual
contamination
C. Hand hygiene is required only before glove donning, never after
D. Alcohol-based hand rubs inactivate gloves and should be avoided
Correct Answer: B
Rationale:
Gloves are not a complete barrier. Hands can be contaminated during glove removal, and hand hygiene after removal is a critical step in
interrupting transmission.
Q4
A laboratory reports a blood culture positive for Candida auris from a patient transferred from a long-term care facility. Why is
this organism of particular concern to infection prevention programs?
A. It is always susceptible to all antifungal agents
B. It is often multidrug-resistant, persists in the environment, and has caused difficult-to-control outbreaks in healthcare settings
C. It causes only mild colonization without clinical significance
D. Standard Contact Precautions are never indicated
Correct Answer: B
Rationale:
C. auris is notable for antifungal resistance, environmental persistence, and outbreak potential, prompting enhanced infection-control
measures.
