Texas Certified Nursing Assistant (CNA)

What is the most important practice a nursing assistant can adopt to prevent disease transmission?

1. Wearing gloves at all times

2. Using hand sanitizer frequently

3. Washing her hands

4. Avoiding close contact with residents

The correct answer is: Washing her hands

The practice of washing hands is the most important method to prevent disease transmission. Hand hygiene is essential in healthcare settings because hands are the primary vehicle for the spread of infections. When nursing assistants wash their hands thoroughly with soap and water, they remove dirt, bacteria, and viruses that could potentially be transmitted to themselves, other staff members, or residents. Proper handwashing techniques include using soap and water for at least 20 seconds, ensuring that all areas of the hands are cleaned, including the backs of hands, between fingers, and under nails. By doing this, nursing assistants effectively reduce the risk of pathogen transmission. While wearing gloves, using hand sanitizer, and avoiding close contact are also important practices in infection control, they are not as fundamental as proper handwashing. Gloves can become contaminated and may give a false sense of security, hand sanitizers are effective but do not eliminate all types of germs as thoroughly as washing hands with soap and water, and avoiding close contact may not always be feasible in a caregiving role. Therefore, frequent and effective handwashing remains the cornerstone of hygiene and disease prevention in healthcare settings.
