CIC - Certification in Infection Prevention and Control Environment of Care Questions and Answers

Question 1

A hospital is beginning a major renovation project directly adjacent to its oncology unit, which houses many immunocompromised patients. According to Infection Control Risk Assessment (ICRA) principles, which of the following is the MOST critical environmental control measure?

Accepted Answer

Establishing rigid, sealed barriers and maintaining negative air pressure within the construction zone.

Answer

The most critical measure is to contain dust and particulates at the source and prevent their aerosolization into patient care areas. Establishing rigid barriers and using HEPA-filtered negative air machines prevents airborne fungal spores (e.g., Aspergillus) and bacteria from reaching high-risk, immunocompromised patients. While other measures are important, they do not address the primary risk of airborne environmental pathogens.

Question 2

An Infection Preventionist is verifying the proper functioning of an Airborne Infection Isolation Room (AIIR). Which of the following air handling specifications is a fundamental requirement for these rooms?

Accepted Answer

Air that is exhausted directly to the outside or recirculated through a HEPA filter.

Answer

The primary purpose of an AIIR is to contain airborne pathogens within the room. This is achieved by maintaining negative pressure and ensuring that air removed from the room is not circulated to other areas of the facility. Therefore, the air must be safely exhausted directly to the outdoors or made safe for recirculation by passing it through a HEPA filter.

Question 3

A hospital's multi-disciplinary team is developing a water management program to prevent healthcare-associated Legionellosis, in alignment with CMS requirements. What is the primary goal of this program?

Accepted Answer

To identify and mitigate hazardous conditions in the building's water systems that could promote the growth and spread of Legionella.

Answer

The core purpose of a water management program, as required by CMS and guided by ASHRAE 188, is to proactively identify risks and implement control measures to minimize the growth and transmission of Legionella and other opportunistic waterborne pathogens. Documentation and monitoring are essential components of the program, but the ultimate objective is the mitigation of hazardous conditions for patient safety.

Question 4

An environmental services (EVS) staff member is performing terminal cleaning on a room that housed a patient with a confirmed *Clostridioides difficile* infection (CDI). Which of the following represents the correct cleaning and disinfection practice?

Accepted Answer

Cleaning surfaces to remove organic matter, followed by application of an EPA-registered sporicidal disinfectant.

Answer

*C. difficile* forms hardy spores that are resistant to many standard hospital disinfectants, including quaternary ammonium compounds and alcohol. CDC guidelines mandate the use of an EPA-registered sporicidal disinfectant (List K), such as a bleach-based product, for the daily and terminal cleaning of rooms for patients with CDI to ensure the spores are inactivated.

Question 5

A Sterile Processing Department (SPD) technician runs a steam sterilization load and discovers the biological indicator (BI) test is positive, indicating a potential sterilization failure. However, the chemical indicators on the packages passed. What is the MOST appropriate immediate action?

Accepted Answer

Immediately quarantine the entire load, retrieve any items that may have been prematurely released, and notify the IP and relevant departments.

Answer

A positive biological indicator signifies that the conditions for sterilization were not met to kill a high number of resistant bacterial spores, representing a failure of the cycle. The entire load is considered non-sterile and must be quarantined immediately. A recall of any distributed items is critical to prevent patient harm, and an investigation into the cause of the failure must be initiated.
