Which practice is the cornerstone of preventing infection in clinical settings?

• A. Wearing gloves and gowns during every activity
• B. Regularly performing hand hygiene to remove pathogens
• C. Relying on antibiotics for everyone
• D. Avoiding PPE whenever possible

Answer: (B)

Regular hand hygiene is the practice that most effectively stops the spread of infection in clinical settings because hands are the primary way pathogens move between patients, surfaces, and healthcare workers. Cleaning hands before touching a patient and after any patient contact or environmental exposure removes transient microorganisms that could be transmitted. Using an alcohol-based hand rub is quick and practical when hands aren’t visibly dirty, while washing with soap and water is necessary when hands are visibly soiled or after exposure to certain pathogens. Proper technique and adequate duration—about 20–30 seconds for hand rubs or longer for washing—make the difference.

Gloves and gowns have protective roles, but they’re not needed for every activity and do not replace the need for hand hygiene. They should be used based on risk and guidelines; overusing them can give a false sense of security and still leave hands as a transmission route. Relying on antibiotics for everyone isn’t a preventive strategy for acquiring infections and contributes to resistance and side effects. Avoiding PPE when it’s indicated increases exposure risk and undermines safety.
