What is the purpose of the five moments for hand hygiene in healthcare?

• A. To ensure all policies are followed.
• B. To standardize when hand hygiene should be performed to prevent transmission.
• C. To measure how fast hands dry.
• D. To identify which patients need isolation.

Answer: (B)

The five moments for hand hygiene establish exactly when healthcare workers should clean their hands to stop the spread of germs. By defining moments such as before touching a patient, before clean/aseptic tasks, after body-fluid exposure risk, after touching a patient, and after touching patient surroundings, the approach creates a consistent, standardized timing for hand hygiene. This focused timing reduces the chance of transferring pathogens between patients, staff, and the environment, which lowers the rate of healthcare-associated infections. The other options aren’t related to when hand hygiene should happen—policies in general, how quickly hands dry, or deciding which patients need isolation—whereas the five moments specifically target preventing transmission through timely hand cleaning.
