Question

which of the following is a signal of infection?
stiffness below the location of the wound.
a bluish color around the site of the wound.
a red and swollen area around the wound.
all of the above

Explanation:

When there is an infection around a wound, the body's immune response causes increased blood flow (leading to redness) and fluid accumulation (causing swelling). Stiffness below the wound location is not a typical direct sign of infection. A bluish color around the wound (cyanosis) is more related to poor blood - oxygenation rather than infection.

Answer:

A red and swollen area around the wound.
