質問 # 183
The infection preventionist recognizes that construction barriers are a key component of the Infection Control Risk Assessment (ICRA). The MOST important factor to consider is that construction barriers should:
正解：A
解説：
The CBIC Certified Infection Control Exam Study Guide (6th edition) emphasizes that the primary purpose of construction barriers within an Infection Control Risk Assessment (ICRA) is to prevent the dissemination of dust and potentially infectious microorganisms generated during construction, renovation, or maintenance activities. Construction activities can aerosolize fungal spores (such as Aspergillus), bacteria, and other particulate matter that pose a significant risk to immunocompromised patients and other vulnerable populations.
Barriers must therefore be designed and maintained to effectively contain dust and microorganisms at the source, preventing their migration into occupied patient care areas. This containment function is the cornerstone of infection prevention during construction and directly aligns with ICRA goals of risk reduction and patient safety.
While the other options describe supportive or secondary considerations, they are not the most critical factor.
Withstanding HVAC airflow (Option A) is important, but it serves the larger goal of containment. Sealing air intakes and exhausts (Option B) is a specific engineering control that may be used as part of containment strategies but does not define the primary purpose of barriers. Walk-off mats (Option D) are useful adjunctive controls but are insufficient alone to prevent airborne transmission of contaminants.
For CIC exam preparation, it is essential to recognize that containment of dust and infectious agents is the defining function of construction barriers within an ICRA, and all other measures support this central objective.
質問 # 184
Which of the following measures has NOT been demonstrated to reduce the risk of surgical site infections?
正解：D
解説：
There is no strong evidence that isolating infected cases in a separate surgical suite reduces SSI risk.
Step-by-Step Justification:
* SSI Prevention Strategies Supported by Evidence:
* Preoperative hospital stay limitation reduces exposure to hospital-acquired pathogens.
* Antimicrobial preoperative scrubs lower bacterial load on the skin.
* Adequate nutrition improves immune function and wound healing.
* Why Designating a Separate Surgical Suite Is Not Effective:
* Operating room environmental controls (e.g., laminar airflow, sterilization protocols) are more important than suite designation.
* No significant reduction in SSIs has been observed by segregating infected cases into specific OR suites.
Why Other Options Are Correct:
* A. Limiting preoperative hospital stay: Reduces nosocomial bacterial exposure.
* B. Antimicrobial preoperative scrub: Decreases skin flora contamination.
* C. Assuring adequate patient nutrition: Enhances immune defense against infections.

質問 # 185
After defining and identifying cases in a possible cluster of infections, an infection preventionist should NEXT establish:
正解：B
解説：
When investigating a possible cluster of infections, an infection preventionist (IP) follows a structured epidemiological approach to identify the cause and implement control measures. The Certification Board of Infection Control and Epidemiology (CBIC) outlines this process within the "Surveillance and Epidemiologic Investigation" domain, which aligns with the Centers for Disease Control and Prevention (CDC) guidelines for outbreak investigation. The steps typically include defining and identifying cases, formulating a hypothesis, testing the hypothesis, and implementing control measures. The question specifies the next step after defining and identifying cases, requiring an evaluation of the logical sequence.
Option C, "A hypothesis that will explain the majority of cases," is the next critical step. After confirming a cluster through case definition and identification (e.g., by time, place, and person), the IP should develop a working hypothesis to explain the observed pattern. This hypothesis might propose a common source (e.g., contaminated equipment), a mode of transmission (e.g., airborne), or a specific population at risk. The CDC's
"Principles of Epidemiology in Public Health Practice" (3rd Edition, 2012) emphasizes that formulating a hypothesis is essential to guide further investigation, such as identifying risk factors or environmental sources.
This step allows the IP to focus resources on testing the most plausible explanation before proceeding to detailed analysis or interventions.
Option A, "The route of transmission," is an important element of the investigation but typically follows hypothesis formulation. Determining the route (e.g., contact, droplet, or common vehicle) requires data collection and analysis to test the hypothesis, making it a subsequent step rather than the immediate next action. Option B, "An appropriate control group," is relevant for analytical studies (e.g., case-control studies) to compare exposed versus unexposed individuals, but this is part of hypothesis testing, which occurs after the hypothesis is established. Selecting a control group prematurely, without a hypothesis, lacks direction and efficiency. Option D, "Whether observed incidence exceeds expected incidence," is a preliminary step to define a cluster, often done during case identification using baseline data or statistical thresholds (e.g., exceeding the mean plus two standard deviations). Since the question assumes cases are already defined and identified, this step is complete, and the focus shifts to hypothesis development.
The CBIC Practice Analysis (2022) and CDC guidelines prioritize hypothesis formulation as the logical next step after case identification, enabling a targeted investigation. This approach ensures that the IP can efficiently address the cluster's cause, making Option C the correct answer.

質問 # 186
Surgical site infection (SSI) data for the previous quarter reveal the following numbers. The surgeon with the highest infection rate is Doctor
正解：A
解説：
To determinewhich surgeon has the highest surgical site infection (SSI) rate, use the following formula:
A screenshot of a report AI-generated content may be incorrect.
SinceDr. White has the highest SSI rate at 9.1%, the correct answer isD. White.
CBIC Infection Control Reference
SSI rates are calculated usinginfection count per total proceduresand reported aspercentage values.
質問 # 187
When assessing a patient's infection prevention and control educational needs, it is necessary to FIRST determine the patient's
正解：C
解説：
The correct answer is D, "baseline knowledge of the subject," as this is the necessary first step when assessing a patient's infection prevention and control educational needs. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, effective patient education in infection prevention and control requires a tailored approach that begins with understanding the patient's existing knowledge and comprehension of the topic. Determining baseline knowledge allows the infection preventionist (IP) to identify gaps, customize educational content to the patient's level of understanding, and ensure the information is relevant and actionable (CBIC Practice Analysis, 2022, Domain IV: Education and Research, Competency 4.1 - Develop and implement educational programs). This step ensures that education is neither too basic nor overly complex, maximizing its effectiveness in promoting behaviors such as hand hygiene, wound care, or adherence to isolation protocols.
Option A (severity of illness) is an important clinical consideration that may influence the timing or method of education delivery, but it is not the first step in assessing educational needs. The severity might affect the patient's ability to learn, but it does not directly inform the content or starting point of the education. Option B (educational background) provides context about the patient's general learning capacity (e.g., literacy level or language preference), but it is secondary to assessing specific knowledge about infection prevention, as background alone does not reveal current understanding. Option C (duration of hospitalization) may impact the opportunity for education but is not a primary factor in determining what the patient needs to learn; it is more relevant to scheduling or prioritizing educational interventions.
The focus on baseline knowledge aligns with adult learning principles endorsed by CBIC, which emphasize assessing learners' prior knowledge to build effective educational strategies (CBIC Practice Analysis, 2022, Domain IV: Education and Research, Competency 4.2 - Evaluate the effectiveness of educational programs).
This approach ensures patient-centered care and supports infection control by empowering patients with the knowledge to participate in their own prevention efforts.
