- Infectious Agent

What are the 7 Principles of Asepsis?
- Sterile objects remain sterile when touched by other sterile objects
- Only sterile objects are to be places within sterile field (2.5cm border)
- Items held below waist level = unsterile
- Sterile objects become contaminated via prolonged exposure to air
- Wicking = when sterile field comes into contact w/ a wet, contaminated surface
- Anything outside 2.5cm border = contaminated
- Fluid flows in direction of gravity

Describe the Third Stage of Pressure Injuries
Full thickness skin loss
Subcutaneous fat may be visible, yellow slough
