Wound Treatment Associate (WTA) Practice Exam

Which characteristic is associated with the inflammatory phase of full-thickness wound healing?

1. Granulation tissue formation

2. Presence of necrotic tissue

3. Scar tissue maturation

4. Increased epithelialization

The correct answer is: Presence of necrotic tissue

The inflammatory phase of full-thickness wound healing is primarily characterized by the body's immediate response to injury, which includes the presence of necrotic tissue. This phase typically occurs within the first few days following an injury and is critical for creating a conducive environment for healing. During this time, the body's immune response is activated, leading to increased blood flow and the movement of immune cells to the wound site. Necrotic tissue may form due to the initial injury or from damage caused by the body's inflammatory response. It is crucial to recognize necrotic tissue during this phase because it can impede healing and lead to infection if not managed properly. The removal of necrotic tissue often takes place in conjunction with subsequent phase transitions in the healing process. The other choices are associated with different phases of healing. Granulation tissue formation typically occurs in the proliferative phase, indicating new tissue growth. Scar tissue maturation occurs during the remodeling phase, which is later in the healing process, and increased epithelialization is also seen as healing progresses after the inflammatory phase. Understanding the role of necrotic tissue during the inflammatory phase helps in effective wound management and treatment strategies.
