Which term means dead or decaying tissue?

• A. Tracheostomy
• B. Edema
• C. Necrosis
• D. Analgesia

Answer: (C)

Dead or decaying tissue is described by necrosis. Necrosis happens when cells or tissue die due to injury, infection, or lack of blood supply, and it can hinder healing and raise infection risk in wounds. In practice, recognizing necrotic tissue helps guide care decisions like debridement to remove it and promote a healthier wound bed. The other terms refer to different concepts: edema is swelling from fluid buildup, a tracheostomy is a surgical airway opening, and analgesia means pain relief. So, necrosis is the term that means dead or decaying tissue.
