Question

Black tissue is characteristic of an eschar. Because the eschar obscures the depth of the wound, this ulcer is unstageable. Stage I ulcers manifest as localized nonblanchable redness over intact skin. Stage II ulcers are characterized by partial-thickness dermis loss. Stage III ulcers are characterized by full-thickness skin loss to the extent that subcutaneous fat may be visible.

a) Eschar
b) Stage I ulcer
c) Stage II ulcer
d) Stage III ulcer

Answer 1

Eschars are characteristic of an eschar and make the wound unstageable. Stage I ulcers show localized nonblanchable redness, Stage II ulcers show partial-thickness dermis loss, and Stage III ulcers show full-thickness skin loss.

Step-by-step explanation:

The question is asking about the characteristics and stages of different types of ulcers. The black tissue mentioned in the question is characteristic of an eschar, which is a scab or dry, dead tissue that forms over a wound or ulcer. Eschars often make it difficult to determine the depth of the wound, resulting in the ulcer being classified as unstageable. On the other hand, Stage I ulcers manifest as nonblanchable redness over intact skin, Stage II ulcers involve partial-thickness dermis loss, and Stage III ulcers involve full-thickness skin loss to the extent that subcutaneous fat may be visible.
