Certification Board of Infection Control and Epidemiology (CBIC) Practice Exam 2026 – The All-in-One Guide for Exam Success

The initial step when using alcohol-based surgical hand scrub products is to prewash hands and forearms with non-antimicrobial soap. This prewashing step is crucial as it helps remove dirt, organic material, and transient microorganisms from the skin's surface, creating a clean starting point for the subsequent application of the alcohol-based scrub.

By removing these contaminants, the efficacy of the alcohol-based product is significantly enhanced, as alcohol works best on clean, dry skin and is not effective against visible soiling. This practice is part of the recommended protocols in infection prevention to ensure that the surgical hand antisepsis process is as effective as possible, reducing the risk of surgical site infections.

Since other options either suggest applying the scrub directly without prior cleaning or involve procedures that don't align with the recommended hand hygiene guidelines, they do not set the appropriate foundation for effective surgical hand antisepsis. Proper adherence to the prewashing step is essential to ensure that health professionals are well-prepared for surgical procedures.
