What is recommended between tasks to prevent cross-contamination?

• A. Sanitize hands or clean equipment
• B. Sit and rest
• C. Change clothing
• D. Ignore contamination risk

Answer: (A)

Between tasks, hand hygiene and cleaning or changing equipment is the key practice to stop cross-contamination. Hands are the main vehicle for transferring germs, so cleaning them before you move to the next task or resident reduces the risk of spreading bacteria or viruses. Using soap and water when hands are visibly dirty, or an alcohol-based hand rub when they aren’t, lowers the microbial load and interrupts transmission. Cleaning or switching to fresh equipment between residents prevents contaminants on tools from moving from one person to another, which is essential for safe care. Resting between tasks doesn’t remove germs, changing clothes isn’t a reliable safeguard on its own, and ignoring contamination risk leaves residents vulnerable, so those options aren’t appropriate.
