Which practice involves cleaning hands to remove pathogens and reduce transmission?

• A. Chain of Infection
• B. Standard Precautions
• C. Medical Asepsis
• D. Hand Hygiene

Answer: (D)

Cleaning hands to remove pathogens and reduce transmission is hand hygiene. This practice is the most effective way to stop the spread of infections because it directly lowers the amount of microorganisms on the hands before they contact patients or surfaces. Hand hygiene can be done with soap and water or with an alcohol-based hand rub, and it’s performed at key moments such as before touching a patient, after contact with a patient or their surroundings, and after removing gloves. It’s a fundamental action that supports infection control by interrupting the route through which pathogens are transmitted.

In contrast, thinking about the chain of infection helps explain how infections spread, but it isn’t the act you perform. Standard precautions are a broad set of rules that include hand hygiene among other safety measures. Medical asepsis refers to the overall approach of preventing infection by keeping things clean and minimizing pathogens, of which hand hygiene is a crucial step.
