When should Nicollette demonstrate proper hand-washing technique?

Demonstrating proper hand-washing technique before and after certain procedures is crucial for infection control and maintaining patient safety. Hand hygiene is one of the most effective ways to prevent the spread of pathogens in healthcare settings.

By washing hands before procedures, Nicollette minimizes the risk of transferring harmful microorganisms to patients, which is essential for maintaining a sterile environment. After procedures, hand washing helps remove any contaminants that may have been transferred during the care process, protecting both the healthcare worker and subsequent patients. This practice is important in various scenarios, including before and after administering medication, changing dressings, or handling any medical equipment.

The other options reflect a limited understanding of when hand hygiene is necessary. For example, only washing before taking vital signs or only after using the restroom misses critical moments when contamination could occur. Similarly, washing only when visibly dirty does not account for the numerous invisible pathogens that can be present and transmitted through unwashed hands. Thus, option C encompasses a broader and more effective approach to hand hygiene in a nursing context.
