1Which CDC publication provides the foundational environmental infection control framework that a consulting environmental infection control consultant would cite when developing a healthcare facility's program?
A.Guidelines for Environmental Infection Control in Health-Care Facilities (Sehulster & Chinn, 2003, with HICPAC updates)
B.FDA 21 CFR 820
C.EPA AP-42 Compilation of Emission Factors
D.OSHA HazCom (29 CFR 1910.1200)
Explanation: Sehulster et al. (2003) Guidelines for Environmental Infection Control in Health-Care Facilities, developed with HICPAC, is the foundational CDC reference for environmental infection control. It covers air, water, surfaces, construction, laundry, and waste in healthcare and is updated periodically.
2Which is true about the consulting role of a CEICC under ASHRAE 188 Water Management Program development?
A.The CEICC writes the program in isolation
B.The CEICC facilitates a multidisciplinary team — engineering, infection prevention, microbiology, environmental services — to develop a documented WMP including hazard analysis, control measures, monitoring, corrective actions, and verification
C.The CEICC reviews only the executive summary
D.The CEICC is excluded from WMP work
Explanation: ASHRAE 188 requires a Building Water Systems team. The CEICC typically facilitates the team — engineering, infection prevention, microbiology, environmental services, facility management — to develop hazard analysis, identify control measures, set critical limits, monitor, take corrective action, and verify.
3Which is the appropriate consulting recommendation for a hospital's ICRA program to align with current FGI Guidelines and CDC practice?
A.Use a single Class II precaution for all renovations
B.Implement the CDC ICRA matrix (Type A-D activity × Group 1-4 patient risk) with documented Class I-IV precautions, signage, daily barrier inspection, dust monitoring, and post-construction verification
C.Skip ICRA for renovations <2 weeks
D.Use ICRA only for ground-up construction
Explanation: Robust ICRA programs follow the CDC matrix with documented Class I-IV precautions, ICRA permit signage at the work zone, daily barrier inspection, real-time particle monitoring (where appropriate), and structured post-construction verification before re-occupancy.
4Which is the appropriate consulting consideration for a Healthcare Acquired Infection (HAI) reduction strategy involving environmental disinfection?
A.Recommend a single 'silver bullet' disinfectant
B.Implement bundle: enhanced cleaning audits with ATP/fluorescent verification, ES staff training, EPA-registered products matched to pathogen (List N/K/P/G), adjunct technology where evidence supports (UV-C, HPV), and IP-led surveillance
C.Replace ES with robotics only
D.Eliminate environmental cleaning
Explanation: Effective HAI reduction through environmental control combines: cleaning audits (ATP, fluorescent), ES training and supervision, EPA-registered products matched to pathogen (List N COVID, List K C. diff, List P C. auris, List G norovirus), adjunct technologies (UV-C, HPV) where evidence supports, and IP-led surveillance.
5Per ASHRAE 170, the typical minimum total ACH for an Airborne Infection Isolation (AII) room is:
A.2 ACH
B.6 ACH (existing/legacy facilities allowed)
C.12 ACH (new construction)
D.30 ACH
Explanation: ASHRAE 170 requires 12 total ACH minimum in AII rooms for new construction; existing facilities are permitted to operate at 6 ACH under some circumstances. AII rooms are negative pressure and exhausted directly outdoors or through HEPA before recirculation.
6Which is the appropriate consulting recommendation for a healthcare facility's Operating Room pressure relationship and humidity?
A.Negative pressure, 0% RH
B.Positive pressure to corridor with minimum 20 total ACH and humidity within FGI/ASHRAE 170 range (commonly 20-60%)
C.Negative pressure, 80% RH
D.Variable pressure based on procedure
Explanation: ORs per FGI/ASHRAE 170 are positive pressure to adjacent corridors with minimum 20 total ACH, with humidity managed within 20-60% RH (per current FGI relaxation to accommodate sterile supply requirements while balancing static control).
7Which is the appropriate consulting recommendation when investigating an Aspergillus cluster in a hematology unit during nearby construction?
A.Limit investigation to clinical chart review
B.Conduct culturable air sampling on Sabouraud/DG18 inside the unit and adjacent zones, audit construction barrier integrity and HEPA negative-pressure containment, inspect HVAC for water-damaged components, review clinical isolates for molecular typing
C.Sample only outdoor air
D.Defer until construction ends
Explanation: Investigation requires: culturable air sampling (Sabouraud/DG18 via Andersen impactor) inside the unit and adjacent zones, audit of barrier and HEPA negative-pressure containment, HVAC inspection for water-damage, and molecular typing of clinical isolates to support environmental linkage.
8Which is the appropriate consulting role of the CEICC in healthcare facility design review?
A.Submit comments after construction is complete
B.Participate in design phase reviews of FGI Guidelines and ASHRAE 170 compliance, focusing on pressure relationships, AII/PE/OR layouts, water distribution dead-leg minimization, sink/handwash placement, ICRA-supportive features, and EHS integration
C.Comment only on flooring colors
D.Stay disengaged
Explanation: Design phase review is one of the highest-value CEICC services: review FGI and ASHRAE 170 compliance, pressure layouts, water distribution to minimize dead legs, sink/handwash placement, ICRA-supportive design (anteroom integration, mechanical access), and integration with EHS.
9Which environmental disinfectant claim category is most relevant for inactivating Clostridioides difficile (C. difficile) spores on environmental surfaces?
A.EPA List N (SARS-CoV-2)
B.EPA List K (sporicidal claims against C. difficile)
C.EPA List G (norovirus)
D.EPA List H (Hepatitis A)
Explanation: EPA List K identifies products with sporicidal claims against C. difficile, typically sodium hypochlorite at 1:10 dilution or specific peracetic-based products. Standard quat disinfectants are not sporicidal.
10Which best describes the role of a CEICC during a Joint Commission survey?
A.Refuse to interact with surveyors
B.Support the facility's IC team in addressing surveyor questions, provide documentation on HVAC, ICRA, WMP, ES audits, and demonstrate corrective action follow-through
C.Replace the Infection Preventionist
D.Block the survey
Explanation: During Joint Commission surveys, the CEICC supports the IC team by providing environmental documentation (HVAC pressure logs, ICRA records, WMP, ES audits), explaining systems to surveyors, and demonstrating corrective action follow-through.
