Which practice is a core component of medical asepsis?

• A. Sterilization
• B. Hand Hygiene
• C. Disinfection
• D. Vaccination

Answer: (B)

Medical asepsis centers on reducing the spread of microorganisms during care. The most effective way to do this is hand hygiene, because hands are the main vehicle for transferring germs between people, surfaces, and objects. Washing with soap and water or using an alcohol-based hand sanitizer dramatically lowers the number of microbes and helps prevent infection with every patient interaction. It’s important to clean hands before touching a patient, after contact with bodily fluids, after removing gloves, and after touching the patient’s environment.

Sterilization targets instruments and materials used for invasive procedures and removes all microorganisms on those items, which is beyond routine patient care. Disinfection lowers the microbial load on surfaces but doesn’t guarantee all pathogens are gone and doesn’t replace the need for hand hygiene. Vaccination prevents certain diseases from developing but isn’t a hands-on practice used to reduce transmission during everyday care.
