質問 # 137
An employee is presenting to Occupational Health for clearance prior to starting work at a healthcare facility.
They have a history of having received the Bacillus Calmette-Guerin (BCG) vaccination. What is the preferred methodology for pre-work clearance?
正解：A
解説：
The preferred methodology for pre-work clearance in this scenario is the interferon-gamma release assay (IGRA), making option C the correct choice. This conclusion is supported by the guidelines from the Certification Board of Infection Control and Epidemiology (CBIC), which align with recommendations from the Centers for Disease Control and Prevention (CDC) for tuberculosis (TB) screening in healthcare workers.
The employee's history of receiving the Bacillus Calmette-Guerin (BCG) vaccination, a vaccine commonly used in some countries to prevent severe forms of TB, is significant because it can cause false-positive results in the traditional Tuberculin skin test (TST) due to cross-reactivity with BCG antigens (CBIC Practice Analysis, 2022, Domain I: Identification of Infectious Disease Processes, Competency 1.3 - Apply principles of epidemiology).
The IGRA, such as the QuantiFERON-TB Gold test, measures the release of interferon-gamma from T-cells in response to specific TB antigens (e.g., ESAT-6 and CFP-10) that are not present in BCG or most non- tuberculous mycobacteria. This makes it a more specific and reliable test for detecting latent TB infection (LTBI) in individuals with a history of BCG vaccination, avoiding the false positives associated with the TST.
The CDC recommends IGRA over TST for BCG-vaccinated individuals when screening for TB prior to healthcare employment (CDC Guidelines for Preventing Transmission of Mycobacterium tuberculosis, 2005, updated 2019).
Option A (referral to tuberculosis clinic) is a general action but not a specific methodology for clearance; it may follow testing if results indicate further evaluation is needed. Option B (initial chest radiograph) is used to detect active TB disease rather than latent infection and is not a primary screening method for pre-work clearance, though it may be indicated if IGRA results are positive. Option D (two-step purified protein derivative-based Tuberculin skin test) is less preferred because the BCG vaccination can lead to persistent cross-reactivity, reducing its specificity and reliability in this context. The two-step TST is typically used to establish a baseline in unvaccinated individuals with potential prior exposure, but it is not ideal for BCG- vaccinated individuals.
The IP's role includes ensuring accurate TB screening to protect both the employee and patients, aligning with CBIC's focus on preventing transmission of infectious diseases in healthcare settings (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.2 - Implement measures to prevent transmission of infectious agents).

質問 # 138
Documentation of each steam sterilization cycle should include which of the following pieces of information?
正解：C
解説：
Documentation of each steam sterilization cycle is a regulatory and quality requirement. It must include load contents, the sterilizer ID, date, cycle number, and the person who assembled the load. These details support traceability and quality assurance.
The APIC Text states:
"Each item or package should be labeled with a lot-control identifier that includes the sterilizer identification number or code, a detailed list of the contents, an identifier for the person who assembled the package, the date of sterilization, the cycle number..." Other options like the machine model number or date sterilizer was cleaned are not routine documentation elements for every cycle.

質問 # 139
What inflammatory reaction may occur in the eye after cataract surgery due to a breach in disinfection and sterilization of intraocular surgical instruments?
正解：A
解説：
The correct answer is C, "Toxic Anterior Segment Syndrome," as this is the inflammatory reaction that may occur in the eye after cataract surgery due to a breach in disinfection and sterilization of intraocular surgical instruments. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, Toxic Anterior Segment Syndrome (TASS) is a sterile, acute inflammatory reaction that can result from contaminants introduced during intraocular surgery, such as endotoxins, residues from improper cleaning, or chemical agents left on surgical instruments due to inadequate disinfection or sterilization processes (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.3 - Ensure safe reprocessing of medical equipment). TASS typically presents within 12-48 hours post-surgery with symptoms like pain, redness, and anterior chamber inflammation, and it is distinct from infectious causes because it is not microbial in origin. A breach in reprocessing protocols, such as failure to remove detergents or improper sterilization, is a known risk factor, making it highly relevant to infection prevention efforts in surgical settings.
Option A (endophthalmitis) is an infectious inflammation of the internal eye structures, often caused by bacterial or fungal contamination, which can also result from poor sterilization but is distinguished from TASS by its infectious nature and longer onset (days to weeks). Option B (bacterial conjunctivitis) affects the conjunctiva and is typically a surface infection unrelated to intraocular surgery or sterilization breaches of surgical instruments. Option D (toxic posterior segment syndrome) is not a recognized clinical entity in the context of cataract surgery; inflammation in the posterior segment is more commonly associated with infectious endophthalmitis or other conditions, not specifically linked to reprocessing failures.
The focus on TASS aligns with CBIC's emphasis on ensuring safe reprocessing to prevent adverse outcomes in surgical patients, highlighting the need for rigorous infection control measures (CBIC Practice Analysis,
2022, Domain III: Infection Prevention and Control, Competency 3.5 - Evaluate the environment for infection risks). This is supported by CDC and American Academy of Ophthalmology guidelines, which identify TASS as a preventable complication linked to reprocessing errors (CDC Guidelines for Disinfection and Sterilization, 2019; AAO TASS Task Force Report, 2017).

質問 # 140
Following recent renovations on an oncology unit, three patients were identified with Aspergillus infections.
The infections were thought to be facility-acquired. Appropriate environmental microbiological monitoring would be to culture the:
正解：D
解説：
The scenario describes an outbreak of Aspergillus infections among three patients on an oncology unit following recent renovations, with the infections suspected to be facility-acquired. Aspergillus is a mold commonly associated with environmental sources, particularly airborne spores, and its presence in immunocompromised patients (e.g., oncology patients) poses a significant risk. The infection preventionist must identify the appropriate environmental microbiological monitoring strategy, guided by the Certification Board of Infection Control and Epidemiology (CBIC) and CDC recommendations. Let's evaluate each option:
* A. Air: Aspergillus species are ubiquitous molds that thrive in soil, decaying vegetation, and construction dust, and they are primarily transmitted via airborne spores. Renovations can disturb these spores, leading to aerosolization and inhalation by vulnerable patients. Culturing the air using methods such as settle plates, air samplers, or high-efficiency particulate air (HEPA) filtration monitoring is a standard practice to detect Aspergillus during construction or post-renovation in healthcare settings, especially oncology units where patients are at high risk for invasive aspergillosis. This aligns with CBIC's emphasis on environmental monitoring for airborne pathogens, making it the most appropriate choice.
* B. Ice: Ice can be a source of contamination with bacteria (e.g., Pseudomonas, Legionella) or other pathogens if improperly handled or stored, but it is not a typical reservoir for Aspergillus, which is a mold requiring organic material and moisture for growth. While ice safety is important in infection control, culturing ice is irrelevant to an Aspergillus outbreak linked to renovations and is not a priority in this context.
* C. Carpet: Carpets can harbor dust, mold, and other microorganisms, especially in high-traffic or poorly maintained areas. Aspergillus spores could theoretically settle in carpet during renovations, but carpets are not a primary source of airborne transmission unless disturbed (e.g., vacuuming). Culturing carpet might be a secondary step if air sampling indicates widespread contamination, but it is less direct and less commonly recommended as the initial monitoring site compared to air sampling.
* D. Aerators: Aerators (e.g., faucet aerators) can harbor waterborne pathogens like Pseudomonas or Legionella due to biofilm formation, but Aspergillus is not typically associated with water systems unless there is significant organic contamination or aerosolization from water sources (e.g., cooling towers). Culturing aerators is relevant for waterborne outbreaks, not for an Aspergillus outbreak linked to renovations, making this option inappropriate.
The best answer is A, culturing the air, as Aspergillus is an airborne pathogen, and renovations are a known risk factor for spore dispersal in healthcare settings. This monitoring strategy allows the infection preventionist to confirm the source, assess the extent of contamination, and implement control measures (e.g., enhanced filtration, construction barriers) to protect patients. This is consistent with CBIC and CDC guidelines for managing fungal outbreaks in high-risk units.
CBIC Infection Prevention and Control (IPC) Core Competency Model (updated 2023), Domain IV:
Environment of Care, which recommends air sampling for Aspergillus during construction-related outbreaks.
CBIC Examination Content Outline, Domain III: Prevention and Control of Infectious Diseases, which includes environmental monitoring for facility-acquired infections.
CDC Guidelines for Environmental Infection Control in Healthcare Facilities (2022), which advocate air culturing to detect Aspergillus post-renovation in immunocompromised patient areas.
質問 # 141
A change in the disinfection protocol is indicated for which of the following scenarios?
正解：B
解説：
The CBIC Certified Infection Control Exam Study Guide (6th edition) emphasizes the importance of applying Spaulding's classification to determine appropriate cleaning, disinfection, and sterilization levels for medical devices based on their intended use. According to this framework, rectal probes are classified as semi-critical devices because they come into contact with mucous membranes. Semi-critical devices require at least high- level disinfection after thorough cleaning.
An enzymatic solution, as listed in option C, is not a disinfectant. Enzymatic detergents are designed solely for cleaning, meaning they help remove organic material such as blood, mucus, and feces, but they do not kill microorganisms. Using an enzymatic solution alone for rectal probes is therefore inadequate and represents an improper disinfection practice, making this the scenario that clearly requires a protocol change.
Option A is acceptable because diaphragm fitting rings are noncritical devices that contact intact skin and may be safely processed using high-level disinfection. Option B is appropriate because blood pressure cuffs are noncritical items and can be disinfected using low- to intermediate-level disinfectants such as sodium hypochlorite. Option D is also appropriate, as cryosurgical probes are semi-critical devices and 2% glutaraldehyde is an accepted high-level disinfectant.
Recognizing the distinction between cleaning versus disinfection and applying the correct level of processing is a core competency for infection preventionists and a frequently tested concept on the CIC exam.
