Removal of foreign matter or dead tissue from a wound is called what?

• A. Aspiration
• B. Incision and drainage
• C. A-line
• D. Debridement

Answer: (D)

Debridement is the process of removing dead tissue and foreign material from a wound to create a clean wound bed that promotes healing and reduces infection. By clearing nonviable tissue and debris, the wound can heal more effectively as healthy tissue can grow into the cleaned area. The other terms refer to different procedures: aspiration removes fluid or air, incision and drainage is used to drain an abscess, and an arterial line is for arterial blood pressure monitoring.
