Final answer:
The statement that wound dressing aims to remove necrotic tissue is true because one of the purposes of wound dressing is to facilitate debridement, clearing away dead tissue to prevent infection and promote healing.
Step-by-step explanation:
A purpose of wound dressing is to remove necrotic tissue. This statement is true. One of the goals of wound dressing is to promote healing by removing nonviable tissue, also known as necrotic tissue, from the wound bed. This process is called debridement, and it can be performed using a variety of methods including surgical, mechanical, enzymatic, or autolytic (allowing the body's own processes to remove the tissue). Removing necrotic tissue is essential as it can harbor bacteria and delay healing, leading to possible infections and complications.
