A nurse is admitting a patient who has a DTI (deep tissue injury) to the hospital. The nurse understands that a DTI:

may be caused when one layer of tissue slides over another layer of tissue.

requires dressing changes twice daily to promote healing.

is usually caused by overhydration.

is a partial thickness injury caused by pressure

Answer and Explanation

The Correct Answer is A

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. Choice C rationale: A DTI is not typically caused by overhydration but is associated with pressure-related damage to underlying tissues.

Choice D rationale: DTI is not a partial thickness injury, but rather an injury to the deep layers of tissue that may not be visible on the surface. A partial thickness injury involves damage to the epidermis and/or dermis, such as a stage 2 pressure ulcer.
