Verified step by step guidance

Understand the importance of hand hygiene in preventing the spread of pathogens. Hand washing is a critical step in infection control, even when gloves are used.

Recognize that gloves do not provide complete protection against all pathogens. Pathogens can still be transmitted through microscopic tears in gloves or during glove removal.

Learn that wearing gloves does not eliminate the need for hand washing. Gloves are a barrier, but hand hygiene is necessary to remove any contaminants that may have come into contact with the skin during glove use.

Understand that hand washing is not limited to situations where gloves are visibly soiled. Pathogens can be present even if there is no visible contamination.

Conclude that hands should always be washed after removing gloves, especially after exposure to blood or other potentially infectious materials, to ensure proper hygiene and reduce the risk of infection.
