Which statement about hand hygiene is true in preventing infection?

• A. It is the most effective measure to prevent the spread of infection
• B. It is optional in most settings
• C. It should only be performed after leaving a patient’s room
• D. It should be performed without soap

Answer: (A)

Hand hygiene is the most essential practice for stopping the spread of infections in healthcare settings. Clean hands remove or kill germs that can be transferred to patients, staff, or surfaces, making it the single most effective measure to prevent infections. This simple action directly interrupts transmission at the point of care and dramatically lowers the risk of healthcare-associated infections when done consistently.

In practice, hand hygiene should occur before touching a patient and after touching a patient or their surroundings, after removing gloves, and after leaving a patient’s room. It is not optional; it’s required in most patient-care situations. It should be performed with soap and water when hands are visibly dirty or when a healthcare facility guidelines call for it (such as after contact with patients with certain infections), otherwise an alcohol-based hand rub is typically used. It should not be done without some cleansing agent, since plain hands without cleaning do not effectively remove or kill germs.
