A client has had an uncomplicated repair of an Inguinal hernia. On the second post-operative day, the client has mildly elevated temperature and general malaise. The nurse recognizes that this is a generalized body response which is common to which phase of healing?

The correct answer is D: Inflammatory phase. Post-operatively, the body responds to tissue injury with inflammation, characterized by redness, warmth, swelling, pain, and fever. Elevated temperature and malaise indicate the body's inflammatory response to the surgical trauma, which is a normal part of the healing process. This phase involves clearing debris, preventing infection, and initiating tissue repair. Remodeling (A) occurs later in the healing process, involving the maturation and reorganization of tissue. Infection (B) would present with localized symptoms and signs of infection, such as purulent discharge and worsening pain. Proliferation (C) is the phase of healing where new tissue is formed to repair the injury, and it does not typically present with fever and malaise.
