The best strategy to reduce the risk of infection in hemodialysis patients is to use an arteriovenous (AV) fistula as the preferred vascular access method. AV fistulas have the lowest infection rates compared to catheters and grafts because they do not involve foreign material and are less prone to biofilm formation and bloodstream infections.

Why the Other Options Are Incorrect?

B. Use of a non-cuffed percutaneous catheter – Non-cuffed catheters have a higher risk of bloodstream infections and should be used only for short-term access.

C. Placement of a femoral catheter – Femoral catheters have higher infection risks and should only be used for bed-bound patients and for the shortest duration possible.

D. Replacement of dialysis catheters monthly – Routine catheter replacement does not reduce infection risk and should be done only when medically necessary.

According to APIC guidelines, AV fistulas are the preferred vascular access due to their lower infection rates and improved long-term outcomes​.

The correct answer is D, "sodium hypochlorite," as it is an effective sporicidal disinfectant for Clostridioides difficile that the infection preventionist (IP) should recommend. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, Clostridioides difficile (C. difficile) is a spore-forming bacterium responsible for significant healthcare-associated infections (HAIs), and its spores are highly resistant to many common disinfectants. Sodium hypochlorite (bleach) is recognized by the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) as a sporicidal agent capable of inactivating C. difficile spores when used at appropriate concentrations (e.g., 1:10 dilution of household bleach) and with the recommended contact time (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.4 - Implement environmental cleaning and disinfection protocols). This makes it a preferred choice for environmental disinfection in outbreak settings or areas with known C. difficile contamination.

Option A (quaternary ammonium compound) is effective against many bacteria and viruses but lacks sufficient sporicidal activity against C. difficile spores, rendering it inadequate for this purpose. Option B (phenolic) has broad-spectrum antimicrobial properties but is not reliably sporicidal and is less effective against C. difficile spores compared to sodium hypochlorite. Option C (isopropyl alcohol) is useful for disinfecting surfaces and killing some pathogens, but it is not sporicidal and evaporates quickly, making it ineffective against C. difficile spores.

The IP’s recommendation of sodium hypochlorite aligns with CBIC’s emphasis on selecting disinfectants based on their efficacy against specific pathogens and adherence to evidence-based guidelines (CBIC Practice Analysis, 2022, Domain III: Infection Prevention and Control, Competency 3.5 - Evaluate the environment for infection risks). Proper use, including correct dilution and contact time, is critical to ensure effectiveness, and the IP should collaborate with the Product Evaluation Committee to ensure implementation aligns with safety and regulatory standards (CDC Guidelines for Environmental Infection Control in Healthcare Facilities, 2019).

The CBIC Certified Infection Control Exam Study Guide (6th edition) emphasizes that measles is a reportable, airborne disease, but actions such as public health notification and contact tracing should occur after appropriate clinical and laboratory confirmation is initiated, unless there is a clear epidemiologic link or high clinical suspicion.

In this scenario, the diagnosis was made solely on the basis of rash, which is insufficient to confirm measles. Many viral illnesses can present with rash, and misclassification can lead to unnecessary alarm, resource use, and disruption. Therefore, the next appropriate step for the infection preventionist is to discuss necessary diagnostic testing with the provider, such as measles-specific IgM serology and PCR testing, to confirm or rule out measles.

Options A and B are premature. Public health notification and contact tracing are essential after measles is suspected and testing is initiated or confirmed, but they should not precede diagnostic clarification when the diagnosis is uncertain. Option D may support clinical assessment but does not replace the need for laboratory confirmation.

The Study Guide highlights that infection preventionists must balance rapid response with diagnostic accuracy. Ensuring appropriate testing is initiated first allows subsequent infection control actions—such as airborne exposure assessment and public health reporting—to be targeted, evidence-based, and defensible.

For the CIC® exam, this question tests understanding of sequencing infection prevention actions, reinforcing that confirmation and testing discussion is the critical next step before escalation.
