Which term refers to the measures that help create barriers between people and germs?

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

Answer: (C)

Creating barriers to infection through isolation precautions helps protect both patients and staff by preventing the spread of germs. This approach includes placing a patient in an appropriate isolation setting when needed, using personal protective equipment, and limiting the sharing of rooms and equipment, along with proper cleaning and visitor policies. PPE is a tool used during isolation precautions, but it alone does not describe the full system of barriers. Hand hygiene reduces the chance of transmitting germs during contact, yet it is a practice rather than the overall barrier framework. Sterilization focuses on removing microorganisms from instruments, not on creating ongoing barriers between people and germs. For these reasons, isolation precautions best represent the measures that establish barriers between people and germs.
