Question

which of the following best defines the term eschar?
multiple choice
to make an incision into the skin
swelling of the tissues around a burn
tissue changes resulting from lack of oxygen
scraping away of the superficial layer
the dead tissue lying on top of third - degree burns

Explanation:

An eschar is defined as the dead tissue that lies on top of third - degree burns. Incision into the skin is a surgical act (not related to eschar). Swelling around a burn is edema. Tissue changes due to lack of oxygen is ischemia - related. Scraping away the superficial layer is debridement (but not specifically eschar).

Answer:

the dead tissue lying on top of third - degree burns
