Answer to Question 1

C
Stage I: Intact skin with nonblanchable redness of a localized area, usually over a bony prominence
Stage II: Partial-thickness loss of dermis presenting as a shallow open ulcer with a red-pink wound bed, without slough; may also present as an intact or open/ruptured serum-filled blister
Stage III: Full-thickness tissue loss; subcutaneous fat may be visible, but bone, tendon, or muscle is not exposed; slough may be present but does not obscure the depth of tissue loss; may include undermining and tunneling
Stage IV: Full-thickness tissue loss with exposed bone, tendon, or muscle

Answer to Question 2

C
As the pain impulse ascends to the brain, the central nervous system extracts information such as location, duration, and quality of the pain impulse. Thus the patient becomes aware of the expe-rience of pain.
