CBIC CIC Exam With Confidence Using Practice Dumps

The gold standard specimen for diagnosing pertussis (Bordetella pertussis infection) is a nasopharyngeal culture because:

B. pertussis colonizes the nasopharynx, making it the best site for detection.

A properly collected nasopharyngeal swab or aspirate increases diagnostic sensitivity.

This method is recommended for culture, PCR, or direct fluorescent antibody testing.

Why the Other Options Are Incorrect?

A. Cough plate – Not commonly used due to low sensitivity.

B. Nares culture – The nares are not a primary site for pertussis colonization.

C. Sputum culture – B. pertussis does not commonly infect the lower respiratory tract.

CBIC Infection Control Reference

APIC confirms that nasopharyngeal culture is the preferred method for diagnosing pertussis​.

When implementing a multimodal strategy (or bundle) for hand hygiene, the infection preventionist should first assess barriers to compliance before implementing solutions.

Step-by-Step Justification:

Understanding Barriers First:

Identifying barriers (e.g., lack of access to sinks, high workload, or poor compliance culture) is critical for effective intervention​.

APIC Guidelines on Hand Hygiene Improvement:

Strategies must be tailored based on the institution's specific challenges​.

Why Other Options Are Incorrect:

A. Signage for hand hygiene reminders:

Signage alone is insufficient without addressing systemic barriers.

B. Cost-effectiveness of hand hygiene products:

While important, cost analysis comes after identifying compliance barriers.

C. Availability of gloves in the patient care area:

Gloves do not replace hand hygiene and may lead to lower compliance.

The correct answer is D, "Cost benefit analysis and safety considerations," as this provides the best information to support the selection of a new catheter aimed at decreasing the rate of catheter-associated urinary tract infections (CAUTIs). According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, selecting medical devices like catheters for infection prevention involves a comprehensive evaluation that balances efficacy, safety, and economic impact. A cost-benefit analysis assesses the financial implications (e.g., reduced infection rates leading to lower treatment costs) against the cost of the new catheter, while safety considerations ensure the device minimizes patient risk, such as reducing biofilm formation or irritation that contributes to CAUTIs (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.3 - Ensure safe reprocessing of medical equipment). This dual focus provides evidence-based data to justify the catheter’s adoption, aligning with the goal of improving patient outcomes and reducing healthcare-associated infections (HAIs).

Option A (staff member preference and product availability) is subjective and logistical rather than evidence-based, making it insufficient for a decision that impacts infection rates. Option B (product materials and vendor information) offers technical details but lacks the broader context of efficacy and cost-effectiveness needed for a comprehensive evaluation. Option C (value analysis and information provided by the manufacturer) includes a structured assessment of value, but it may be biased toward the manufacturer’s claims and lacks the independent safety and cost-benefit perspective critical for infection prevention decisions.

The emphasis on cost-benefit analysis and safety considerations reflects CBIC’s priority on using data-driven and patient-centered approaches to select interventions that enhance infection control (CBIC Practice Analysis, 2022, Domain II: Surveillance and Epidemiologic Investigation, Competency 2.5 - Use data to guide infection prevention and control strategies). This approach ensures the catheter’s selection is supported by robust evidence, optimizing both clinical and economic outcomes in the prevention of CAUTIs.
