When is hand washing recommended over hand sanitizers?

• A. When hands are visibly dirty.
• B. Before entering a patient room.
• C. After using gloves.
• D. When hands are dry.

Answer: (A)

When hands are visibly dirty, washing with soap and water is preferred. Soap and water physically remove dirt, debris, and many microorganisms through mechanical action, which alcohol-based hand sanitizers can’t do when hands are soiled. Some pathogens, and occupational contamination with protein-rich material or spores (like C. difficile), are less effectively addressed by sanitizers, making washing the better choice in those situations. Hand sanitizers are convenient and effective when hands are not visibly dirty, but they won’t remove visible grime or all types of organisms. The other scenarios aren’t as definitive for preferring washing: sanitizers can be used before entering a patient room or after removing gloves if hands are clean, and dryness isn’t a criterion that dictates washing.
