The nurse would document the healing process as Primary intention.
Step-by-step explanation:
The nurse would document the healing process as Primary intention. Primary intention refers to the healing of a wound where the edges are close enough to be brought together and fastened, allowing for quicker and more thorough healing. In this case, the 6-inch abdominal wound is well approximated and closed with surgical suture, and there is no redness or drainage, indicating a primary intention healing process.
