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 # 173
An infection preventionist is educating healthcare personnel on standard precautions and isolation requirements. Sessions consist of large group lectures and demonstrations. Three months later, a carbapenem- resistant Enterobacterales (CRE) outbreak occurs. Which of the following strategies will minimize the risk of a subsequent outbreak?
正解：D
解説：
The Certification Study Guide (6th edition) stresses that education alone is insufficient to ensure sustained adherence to infection prevention practices. While lectures and demonstrations are valuable for knowledge dissemination, they do not guarantee consistent behavioral compliance over time. In this scenario, the occurrence of a CRE outbreak three months after education indicates a gap between knowledge and practice.
To minimize the risk of a subsequent outbreak, the most effective strategy is directly assessing staff compliance with isolation precautions, which is best accomplished by engaging managers and leadership. The study guide emphasizes the importance of monitoring, auditing, and feedback as core components of an effective infection prevention program. Managers are uniquely positioned to observe daily practice, reinforce expectations, and hold staff accountable for adherence to standard and transmission-based precautions.
The other options focus primarily on educational reinforcement rather than practice validation. Updating content, testing knowledge, or offering recorded lectures may improve awareness but do not address whether staff are actually implementing precautions correctly at the point of care. CRE transmission is most often linked to failures in hand hygiene, contact precautions, and environmental cleaning-issues that require ongoing observation and performance management, not passive education.
This question reflects a common CIC exam theme: preventing outbreaks requires behavioral verification and leadership engagement, not education alone. By assessing and reinforcing compliance through managers, the infection preventionist addresses the root cause of transmission risk and supports sustainable prevention.

質問 # 174
The BEST choice for surgical instrument cleaning and material compatibility is a detergent solution with:
正解：B
解説：
The Certification Study Guide (6th edition) emphasizes that the primary goal of surgical instrument cleaning is to remove organic and inorganic soil while preserving the integrity and functionality of the instrument. For this reason, detergents with a neutral pH are considered the best choice for routine surgical instrument cleaning and material compatibility.
Neutral pH detergents are effective at removing blood, tissue, and other organic matter without causing corrosion, pitting, or degradation of metals, plastics, seals, and coatings commonly used in surgical instruments. The study guide notes that repeated exposure to harsh chemical environments can damage instruments, compromise device performance, and shorten instrument lifespan-ultimately affecting patient safety and increasing replacement costs.
Acidic detergents may be used selectively for removal of mineral deposits or water scale but are not appropriate for routine cleaning due to their corrosive potential. Sodium hypochlorite (bleach) is strongly discouraged for surgical instruments because it is highly corrosive and can rapidly damage stainless steel.
Quaternary ammonium compounds are low-level disinfectants and are not suitable for cleaning critical or semi-critical medical devices prior to disinfection or sterilization.
This question reflects a high-yield CIC exam principle: effective cleaning must balance soil removal with material compatibility. Neutral pH detergents best meet both requirements and are widely recommended by manufacturers and reprocessing standards for surgical instrumentation.

質問 # 175
The infection preventionist notes an increase in Clostridioides difficile infections (CDI) in the ICU. A Root Cause Analysis (RCA) is scheduled. What is the goal of a Root Cause Analysis?
正解：D
解説：
The CBIC Certified Infection Control Exam Study Guide (6th edition) defines a Root Cause Analysis (RCA) as a retrospective, systematic process used to understand why an adverse event or undesired outcome occurred and what system-level changes are needed to prevent it from happening again. In the context of an increase in Clostridioides difficile infections in an ICU, the primary goal of an RCA is to identify underlying process failures and implement corrective actions to prevent recurrence.
RCA focuses on systems and processes rather than individual performance. Through structured methods such as event mapping, cause-and-effect analysis, and contributing factor review, the team examines elements such as antimicrobial use, environmental cleaning practices, hand hygiene compliance, isolation implementation, diagnostic testing practices, and workflow design. The ultimate outcome of an RCA is a set of actionable, sustainable process improvements that reduce the likelihood of similar events in the future.
Option A describes Failure Mode and Effects Analysis (FMEA), which is a proactive risk assessment tool.
Option C refers to a SWOT analysis, used for strategic planning rather than event investigation. Option D reflects an important principle of RCA culture (non-punitive), but it is not the primary goal.
For the CIC exam, it is essential to recognize that the core purpose of RCA is preventing recurrence through system improvement, making option B the correct answer.
質問 # 176
Which humoral antibody indicates previous infection and assists in protecting tissue?
正解：B
解説：
Humoral antibodies, or immunoglobulins, play distinct roles in the immune system, and their presence or levels can provide insights into infection history and ongoing immune protection. The Certification Board of Infection Control and Epidemiology (CBIC) recognizes the importance of understanding immunological responses in the "Identification of Infectious Disease Processes" domain, which is critical for infection preventionists to interpret diagnostic data and guide patient care. The question focuses on identifying the antibody that indicates a previous infection and assists in protecting tissue, requiring an evaluation of the functions and kinetics of the five major immunoglobulin classes (IgA, IgD, IgG, IgM, IgE).
Option C, IgG, is the correct answer. IgG is the most abundant antibody in serum, accounting for approximately 75-80% of total immunoglobulins, and is the primary antibody involved in long-term immunity. It appears in significant levels after an initial infection, typically rising during the convalescent phase (weeks to months after exposure) and persisting for years, serving as a marker of previous infection.
IgG provides protection by neutralizing pathogens, opsonizing them for phagocytosis, and activating the complement system, which helps protect tissues from further damage. The Centers for Disease Control and Prevention (CDC) and clinical immunology references, such as the "Manual of Clinical Microbiology" (ASM Press), note that IgG seroconversion or elevated IgG titers are commonly used to diagnose past infections (e.
g., measles, hepatitis) and indicate lasting immunity. Its ability to cross the placenta also aids in protecting fetal tissues, reinforcing its protective role.
Option A, IgA, is primarily found in mucosal secretions (e.g., saliva, tears, breast milk) and plays a key role in mucosal immunity, preventing pathogen adhesion to epithelial surfaces. While IgA can indicate previous mucosal infections and offers localized tissue protection, it is not the primary systemic marker of past infection or long-term tissue protection, making it less fitting. Option B, IgD, is present in low concentrations and is mainly involved in B-cell activation and maturation, with no significant role in indicating previous infection or protecting tissues. Option D, IgM, is the first antibody produced during an acute infection, appearing early in the immune response (within days) and indicating current or recent infection. However, its levels decline rapidly, and it does not persist to mark previous infection or provide long-term tissue protection, unlike IgG.
The CBIC Practice Analysis (2022) and CDC guidelines on serological testing emphasize IgG's role in assessing past immunity, supported by immunological literature (e.g., Janeway's Immunobiology, 9th Edition). Thus, IgG is the humoral antibody that best indicates previous infection and assists in protecting tissue, making Option C the correct choice.
