The correct answer is C, "Reviewing principles of adult learning," as this activity will best prepare a newly hired infection preventionist to present information at the facility’s orientation program. According to the Certification Board of Infection Control and Epidemiology (CBIC) guidelines, effective education delivery, especially for healthcare professionals during orientation, relies on understanding adult learning principles (e.g., andragogy), which emphasize learner-centered approaches, relevance to practice, and active participation. Reviewing these principles equips the infection preventionist (IP) to design and deliver content that addresses the specific needs, experiences, and motivations of the audience—such as new staff learning infection control protocols—enhancing engagement and retention (CBIC Practice Analysis, 2022, Domain IV: Education and Research, Competency 4.1 - Develop and implement educational programs). This preparation ensures the presentation is tailored, impactful, and aligned with the goal of promoting infection prevention behaviors.

Option A (observing other departments’ orientation presentations) can provide insights into presentation styles or facility norms, but it is less focused on the IP’s specific educational role and may not address the unique content of infection prevention. Option B (meeting with the facility’s leadership) is valuable for understanding organizational priorities and gaining support, but it is more about collaboration and context-setting rather than direct preparation for presenting educational material. Option D (administering tuberculin skin tests to orientees) is a clinical task related to TB screening, not a preparatory activity for designing or delivering an educational presentation.

The focus on reviewing adult learning principles aligns with CBIC’s emphasis on evidence-based education strategies to improve infection control practices among healthcare personnel (CBIC Practice Analysis, 2022, Domain IV: Education and Research, Competency 4.2 - Evaluate the effectiveness of educational programs). This approach enables the IP to effectively communicate critical information, such as hand hygiene or isolation protocols, during the orientation program.
