Final answer:
A stage II pressure ulcer involves partial-thickness loss of the dermis. The statements in the question are true.
Step-by-step explanation:
A stage II pressure ulcer involves partial-thickness loss of the dermis and manifests as a red-pink, open ulcer without slough. A stage I pressure ulcer presents as intact, nonblanchable, red skin, often over a bony prominence. A stage III pressure ulcer involves full-thickness tissue loss so that subcutaneous fat is visible. A stage IV pressure ulcer involves full-thickness tissue loss extending to and exposing bone, tendon, and/or muscle.
The statements in the question are true. A stage II pressure ulcer is characterized by partial-thickness loss of the dermis, typically appearing as a shallow open ulcer with a red-pink color. It does not have slough, which is dead tissue that appears yellow and may need to be removed for proper healing.
