Correct Answer is A

Explanation

Choice A rationale: A DTI is a type of pressure injury that occurs when the skin and underlying soft tissue are compressed between a bony prominence and an external surface for a prolonged period of time.

Choice B rationale: Dressing changes for a DTI would depend on the severity and characteristics of the injury, but a specific frequency is not universally prescribed.
