Which of the following actions is essential in infection control for EMTs?

Hand washing before and after patient contact is considered essential in infection control for EMTs because it is one of the most effective ways to prevent the spread of infections. When EMTs wash their hands, they significantly reduce the likelihood of transferring pathogens from one patient to another or from themselves to patients. This action disrupts the chain of infection, which is crucial in providing safe and effective care. By thoroughly washing hands with soap and water or using an alcohol-based hand sanitizer when soap is not available, EMTs help protect both their patients and themselves from potential infections.

While the other options, such as using gloves, keeping equipment sterile, and limiting patient interactions, also contribute to infection control practices, hand hygiene is fundamentally prioritized because of its proven efficacy. Gloves and sterilized equipment can still be compromised, and limiting interactions may not always be feasible. Therefore, ensuring proper hand hygiene serves as a primary line of defense in maintaining a safe healthcare environment.
