Tunneling is defined as what in wound assessment?

• A. A narrow passageway under the skin in a wound
• B. A type of ulcer
• C. A type of exudate
• D. A sign of infection

Answer: (A)

Tunneling is a narrow passageway that extends from the wound bed under the surface of the skin. This channel can run in various directions and may be deeper than the apparent wound opening, sometimes needing probing to identify its length and path. Recognizing tunneling is important because it affects healing plans—closing only the surface won’t address the tunnel itself, which may require targeted debridement or treatment of the surrounding tissue to prevent fluid buildup or infection. This feature is distinct from undermining (where tissue under the wound edge is lost, creating a void beneath the edge) and is not itself an ulcer, exudate, or a sign of infection.
