Environment of Care Flashcards

An infection preventionist is reviewing the ICRA (Infection Control Risk Assessment) for a renovation project. Which patient population warrants the most stringent Class IV containment measures?

Answer: Severely immunocompromised hematology/oncology inpatients

Severely immunocompromised patients (e.g., stem cell transplant recipients) face the highest risk from construction-related fungal exposure and require Class IV ICRA measures.

Which disinfectant is the preferred choice for environmental surfaces contaminated with Clostridioides difficile spores?

Answer: EPA-registered sodium hypochlorite (bleach) solution

EPA-registered sodium hypochlorite (bleach) is sporicidal and is the recommended disinfectant for C. difficile-contaminated environmental surfaces.

What is the primary purpose of a 'protective environment' (PE) room in infection prevention?

Answer: Protect a severely immunocompromised patient from external environmental pathogens

A protective environment uses positive pressure and HEPA filtration to protect severely immunocompromised patients from exogenous airborne pathogens, particularly fungi.

A hospital observes an increase in gram-negative infections traced to shared equipment. Which practice most directly reduces this risk?

Answer: Dedicating or thoroughly disinfecting equipment between patients

Dedicating equipment to individual patients or rigorously disinfecting shared equipment between patients is the most direct way to interrupt gram-negative transmission via fomites.

Which agency publishes the primary guidelines for ventilation requirements in healthcare facilities referenced by the CIC exam?

Answer: American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)

ASHRAE Standard 170 (Ventilation of Health Care Facilities) is the primary reference for healthcare ventilation requirements and is widely adopted in building codes.

Improper reprocessing of flexible endoscopes most frequently leads to which type of healthcare-associated infection (HAI) transmission?

Answer: Direct inoculation of pathogens during the procedure

Inadequately reprocessed endoscopes can directly inoculate patients with residual pathogens from previous patients during invasive procedures.

What is the appropriate dwell time consideration when using a disinfectant wipe on a patient care surface?

Answer: The surface must remain visibly wet for the manufacturer-specified contact time

Disinfectants must remain in contact with the surface (stay wet) for the manufacturer-specified dwell time to achieve the labeled kill claims.
