Which term refers to the precautions used to prevent transmission of infection by creating barriers between patients and germs?

• A. Isolation Precautions
• B. Isolation
• C. Hand Hygiene
• D. Sterilization

Answer: (A)

The concept being tested is how protective actions create barriers to stop infection from spreading. The term that covers the precautions used to prevent transmission by creating barriers between patients and germs is Isolation Precautions. These are the formal guidelines that dictate how to prevent spread—through personal protective equipment, patient placement, dedicated equipment, and other practices tailored to how the infection is transmitted (contact, droplet, airborne).

Hand hygiene is a crucial component of infection control, and sterilization is about cleaning and removing microorganisms from equipment, but neither by itself describes the whole system of protective measures aimed at blocking transmission. Isolation, in general, can refer to separating a patient, but the specific set of precautions designed to create barriers is Isolation Precautions.
