CHC CHC Infection Control & Interim Life Safety 1 — Questions and Answers
Question 1: What does ICRA stand for in healthcare construction?
- Infection Control Risk Assessment (Correct answer)
- Interim Construction Risk Analysis
- Infectious Containment Remediation Action
- Interior Construction Regulatory Assessment
Correct answer: Infection Control Risk Assessment
ICRA stands for Infection Control Risk Assessment, a process used to identify and mitigate infection risks during healthcare construction activities.
Question 2: Which ICRA class level requires the highest level of infection control measures during construction?
- Class I
- Class II
- Class III
- Class IV (Correct answer)
Correct answer: Class IV
ICRA Class IV requires the most stringent infection control measures, used for high-risk construction near immunocompromised patients.
Question 3: During ICRA, which patient population is considered highest risk for construction-related infections?
- Ambulatory care patients
- Transplant and immunocompromised patients (Correct answer)
- General medical-surgical patients
- Emergency department patients
Correct answer: Transplant and immunocompromised patients
Transplant and immunocompromised patients face the greatest risk from construction-related pathogens such as Aspergillus due to their compromised immune systems.
Question 4: What is the primary fungal pathogen of concern during healthcare construction projects?
- Candida albicans
- Cryptococcus neoformans
- Aspergillus fumigatus (Correct answer)
- Mucor species
Correct answer: Aspergillus fumigatus
Aspergillus fumigatus is the primary construction-related pathogen of concern because it releases airborne spores during demolition and excavation.
Question 5: What barrier type is required for ICRA Class III and IV construction projects?
- Plastic sheeting only
- Solid barriers such as drywall with negative air pressure (Correct answer)
- Tape on floors only
- Rope and signage barriers
Correct answer: Solid barriers such as drywall with negative air pressure
Class III and IV ICRA projects require solid barriers such as drywall combined with negative air pressure to prevent dust and spore migration into patient areas.
Question 6: Before starting ICRA Class IV work, contractors must ensure which of the following is established?
- Patients are notified via email
- HEPA filtration and negative pressure containment (Correct answer)
- Only weekend work hours are used
- An architect signs off on aesthetics
Correct answer: HEPA filtration and negative pressure containment
ICRA Class IV work requires HEPA filtration and negative air pressure containment to prevent airborne contaminants from reaching vulnerable patient care areas.
