Score Higher on Verified CIC | CBIC Certified Infection Control Exam Questions with Answers

Even if the healthcare worker is negative for bloodborne pathogens, the patient has the right to be informed of a potential exposure. Transparency builds trust and aligns with ethical obligations in patient care.

The APIC Text states:

“Providers should inform patients when an HAI or other exposure event occurs, regardless of whether the exposure results in harm or is caused by negligence.” Courts and professional guidelines support disclosure.

CBIC and OSHA guidelines emphasize prompt and transparent reporting of exposures.

Options C and D are incorrect because the lack of infection does not negate the ethical duty to inform the patient.

The Certification Study Guide (6th edition) explains that device-associated infection rates are calculated using a standardized formula that expresses the number of infections per 1,000 device days. This allows comparison over time and between units with different patient volumes or device utilization.

The formula for ventilator-associated pneumonia (VAP) rate is:

(Number of VAPs ÷ Number of ventilator days) × 1,000

In this scenario, there were 8 ventilator-associated pneumonias and 240 ventilator days over the 6-month period.

8 ÷ 240 = 0.033

0.033 × 1,000 = 33.3 VAPs per 1,000 ventilator days

Rates are typically rounded to a whole number for reporting and benchmarking purposes, resulting in 33 per 1,000 ventilator days.

The study guide emphasizes that ventilator days—not patient days or admissions—are the correct denominator because they reflect time at risk for ventilator-associated infection. This approach ensures valid surveillance and supports accurate trend analysis and benchmarking.

The other answer choices represent incorrect calculations or decimal misplacement. Understanding rate calculations is a core CIC exam competency, particularly for interpreting device-associated infection data and guiding quality improvement initiatives in high-risk units such as NICUs.

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.
