What is the primary use of SWFI in sterile procedures?

• A. Used to irrigate wounds or body cavities
• B. Used as IV fluid
• C. Used for oral hydration
• D. Used for sterilizing equipment

Answer: (A)

SWFI is sterile, pyrogen-free water specifically used in sterile procedures as a fluid to flush and rinse wounds or body cavities. This irrigation helps remove debris and contaminants while keeping the area clean during procedures. It isn’t used as an IV fluid because plain water, even when sterile, is hypotonic and can cause red blood cells to lyse if infused intravenously; IV fluids are designed to be isotonic and electrolyte-balanced. It also isn’t chosen for oral hydration or for sterilizing equipment, since those roles rely on other solutions and sterilization methods rather than sterile water for injection.
