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.

The Certification Study Guide (6th edition) emphasizes that educational objectives must be written using measurable, observable action verbs that clearly define learner outcomes. This principle is grounded in adult learning theory and Bloom’s taxonomy, both of which are highlighted in the education and communication sections of the guide. Effective objectives allow educators to evaluate whether learning has occurred by observing or assessing learner performance.

The verb “know” is considered inappropriate because it is vague and not measurable. It does not specify how the learner will demonstrate knowledge, making it impossible to objectively assess whether the objective has been achieved. For this reason, “know” is frequently cited in the study guide as an example of a poorly written objective verb.

In contrast, verbs such as define, compare, and explain are acceptable because they describe specific actions the learner can perform. These verbs allow the instructor to evaluate learning through verbal responses, written assessments, or demonstrations. The study guide stresses that well-written objectives should answer the question: What will the learner be able to do at the end of the session?

This concept is commonly tested on the CIC exam because infection preventionists are expected to design and deliver education effectively. Clear, measurable objectives support competency-based education, documentation of learning outcomes, and program evaluation—all essential components of a successful infection prevention program.

The CBIC Certified Infection Control Exam Study Guide (6th edition) follows the standardized surveillance methodology used for calculating central line days, which is essential for accurate reporting of central line–associated bloodstream infection (CLABSI) rates. A central line day is counted for each patient who has one or more central lines in place at the time of the daily count, regardless of the number of central lines present.

Therefore, if a patient has more than one central line, the patient is still counted as one central line day, making option C the correct statement. This approach ensures consistency and comparability of CLABSI rates across units and facilities.

Option A is incorrect because tunneled central venous catheters and implanted ports are included in central line counts if they meet the definition of a central line. Option B is incorrect because a central line is counted on any day it is present, even if it has been in place for less than 24 hours. Option D is incorrect because peripheral intravenous lines are not central lines and must never be included in central line day counts.

Accurate calculation of device days is a foundational surveillance competency for infection preventionists. Understanding these definitions is critical for valid CLABSI rate calculation, benchmarking, and performance improvement and is a frequently tested concept on the CIC® exam.

The CBIC Certified Infection Control Exam Study Guide (6th edition) defines prophylactic antimicrobial therapy as the use of antibiotics to prevent infection in the absence of clinical signs or symptoms of active disease. In this scenario, the patient has a history of Clostridioides difficile infection but is currently asymptomatic for diarrhea or other CDI manifestations. The antibiotic is therefore not being used to treat active infection.

Empiric therapy (Option A) is initiated when infection is suspected but the causative organism has not yet been identified—this does not apply here, as the patient has no symptoms suggesting infection. Targeted therapy (Option D) requires laboratory confirmation of a specific pathogen, which is also not present. While prescribing antibiotics in patients with prior CDI may be clinically questionable depending on indication and stewardship principles, the type of therapy being applied is best categorized as prophylactic, not inappropriate, based on standard antimicrobial definitions.

The Study Guide emphasizes that antimicrobial stewardship programs carefully evaluate prophylactic antibiotic use because unnecessary exposure can disrupt normal flora and increase the risk of CDI recurrence. However, from a classification standpoint, antibiotics given without signs of active infection fall under prophylactic use.

For CIC® exam preparation, it is important to correctly identify antimicrobial intent, even when clinical appropriateness may be debatable.

The CBIC Certified Infection Control Exam Study Guide (6th edition) identifies Neisseria meningitidis as a highly transmissible organism spread through respiratory droplets and direct contact with oral secretions. Healthcare personnel who have unprotected, close exposure—such as mouth-to-mouth resuscitation—to a patient with meningococcal meningitis are considered high-risk contacts.

In this scenario, the nurse had direct exposure to respiratory secretions during CPR, which constitutes a significant risk for transmission. The Study Guide emphasizes that postexposure chemoprophylaxis is indicated as soon as possible, ideally within 24 hours of exposure, to prevent invasive meningococcal disease. Recommended prophylactic agents include rifampin, ciprofloxacin, or ceftriaxone, depending on contraindications and institutional protocols.

Option A is incorrect because chlorhexidine oral rinse does not eliminate systemic infection risk. Option B is inappropriate because quarantine is not required for exposed healthcare workers who receive appropriate prophylaxis. Option D is insufficient, as monitoring alone does not adequately reduce the risk of developing disease following high-risk exposure.

Rapid initiation of chemoprophylaxis is a critical infection prevention intervention and a high-yield CIC® exam concept. Early action protects the exposed healthcare worker and prevents secondary transmission within the healthcare setting.

The Certification Study Guide (6th edition) outlines a structured approach to outbreak investigation, emphasizing that the first step is to verify the problem and establish baseline facts before initiating control measures. When an infection preventionist becomes aware of potential clustering—such as multiple newborn readmissions with staphylococcal infections—the initial priority is to review the medical records of the affected cases.

Reviewing records allows the IP to confirm diagnoses, identify common organisms, determine timing of symptom onset, and assess potential epidemiologic links (e.g., same nursery, staff exposure, procedures, or length of stay). This step helps determine whether the cases represent a true outbreak, coincidental community-acquired infections, or unrelated events. The study guide stresses that interventions should not begin until the problem is clearly defined, as premature actions may waste resources or obscure the true source.

The other options are appropriate later steps in an investigation. Observing practices and obtaining surveillance cultures are targeted control measures that should follow confirmation of an outbreak and hypothesis generation. Beginning prospective surveillance is also important, but only after case definitions and baseline data are established.

CIC exam questions frequently test sequencing of outbreak investigation steps. Recognizing that case confirmation and record review come first is essential for effective infection prevention decision-making and accurate epidemiologic analysis.

The incidence rate measures new cases of infection in a population over a defined time period using the formula:

Why the Other Options Are Incorrect?

B. Disease specific – Refers to infections caused by a particular pathogen, not the general rate of new infections.

C. Point prevalence – Measures existing cases at a specific point in time, not new cases.

D. Period prevalence – Includes both old and new cases over a set period, unlike incidence, which only considers new cases.

APIC defines incidence rate as the number of new infections in a population over a given period​.

The CBIC Certified Infection Control Exam Study Guide (6th edition) emphasizes that education and training on safe work practices must be specific to the job or task performed. This principle aligns with occupational safety and infection prevention standards, which recognize that risks vary significantly depending on an employee’s role, responsibilities, and work environment. Training is most effective when it directly addresses the actual hazards staff may encounter and the specific procedures they are expected to perform.

Job- and task-specific training ensures that healthcare personnel understand how to apply safe practices in real-world situations, such as proper use of personal protective equipment, safe handling of sharps, device reprocessing, and exposure prevention. Generic or overly broad education may fail to address critical nuances and can result in gaps in compliance or increased risk of injury and infection.

Option B is incorrect because safety education is not optional and must be provided at orientation and ongoing as needed. Option C is misleading; while training should be provided in a language and format the employee understands, there is no concept of a single “nationally approved language.” Option D describes a possible timing for education but does not capture the core requirement that training be tailored to specific work activities.

For the CIC® exam, this question reinforces that effective infection prevention and occupational safety education must be job- and task-specific, making option A the correct answer.

The correct answer is C, "Rate of multi-drug resistant organisms acquisition," as it represents an example of an outcome measure. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, outcome measures are indicators that reflect the impact or result of infection prevention and control interventions on patient health outcomes or the incidence of healthcare-associated infections (HAIs). The rate of multi-drug resistant organisms (MDRO) acquisition directly measures the incidence of new infections caused by resistant pathogens, which is a key outcome affected by the effectiveness of infection control practices (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.4 - Evaluate the effectiveness of infection prevention and control interventions).

Option A (hand hygiene compliance rate) is an example of a process measure, which tracks adherence to specific protocols or practices intended to prevent infections, rather than the resulting health outcome. Option B (adherence to environmental cleaning) is also a process measure, focusing on the implementation of cleaning protocols rather than the end result, such as reduced infection rates. Option D (timing of preoperative antibiotic administration) is another process measure, assessing the timeliness of an intervention to prevent surgical site infections, but it does not directly indicate the outcome (e.g., infection rate) of that intervention.

Outcome measures, such as the rate of MDRO acquisition, are critical for evaluating the success of infection prevention programs and are often used to guide quality improvement initiatives. This aligns with CBIC’s emphasis on using surveillance data to assess the effectiveness of interventions and inform decision-making (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.5 - Use data to guide infection prevention and control strategies). The focus on MDRO acquisition specifically highlights a significant healthcare challenge, making it a prioritized outcome measure in infection control.

When a positive biological indicator (BI) is detected, the immediate response is to retest the sterilizer using another BI to confirm results. This helps distinguish between a true sterilization failure and a defective BI.

The CBIC Study Guide advises:

“If there is no indication of abnormalities, then the sterilizer should be tested again in three consecutive cycles using paired biological indicators from different manufacturers.”

Immediate recall is reserved for implant loads or confirmed sterilization failure.

Incorrect responses:

A. Check employee technique may be appropriate later but not as a first step.

B. Informing risk manager or C. Notifying patients occurs only after confirmation of failure.
