During assessment of a client's infection site, the nurse determines that the site is warm to the touch. How should the nurse explain this warmth to the client?

1. "Infection causes fluid overload in your body, so the infected site gets warm and red." 2. "Your lymphatic system has shut down to keep the infection from spreading, so the site gets warm and red." 3. "The little vessels around your infection are leaking, so the area gets warm and red." 4. "Your body is sending extra blood and white cells to the site to fight the infection."
