South Dakota CNA Level 3 Practice Exam 2025 – Complete Study Resource

Handwashing is a fundamental practice in infection control and is widely recognized as one of the most effective ways to prevent the spread of nosocomial infections, which are infections acquired in a healthcare setting. When a CNA regularly washes their hands with soap and water or uses hand sanitizer when soap is unavailable, they significantly reduce the number of pathogens on their skin. This practice is essential before and after patient contact, after using the restroom, and before preparing or handling food.

While wearing gloves can protect both the CNA and patients when handling potentially infectious materials, gloves can give a false sense of security and may contribute to spreading bacteria if not used properly. Using hand sanitizers is also important but should not replace handwashing, especially when hands are visibly soiled. Limiting visitor access is a strategy that can reduce traffic and potential exposure in a healthcare setting, but it does not directly target the prevention of infections at the level of individual caregiver practices. Thus, handwashing stands out as the most effective and practical measure to prevent the transmission of infections in a clinical environment.
