Verified step by step guidance

Understand the concept of innate immunity: Innate immunity is the body's first line of defense against pathogens and includes physical barriers, chemical barriers, and cellular responses.

Identify the role of a nursing assistant in infection prevention: Nursing assistants play a crucial role in maintaining hygiene and preventing the spread of infections in healthcare settings.

Evaluate the options provided: Consider the effectiveness of each option in preventing infection as part of innate immunity.

Analyze why regular hand washing is effective: Hand washing physically removes pathogens from the skin, reducing the risk of transmission and infection.

Conclude that regular hand washing is the most effective method: It is a simple, cost-effective, and universally recommended practice to prevent infections and support innate immunity.
