Final answer:
Hydrocolloid dressing is the type of dressing that remains in place for three to seven days and promotes wound healing.
Step-by-step explanation:
The type of dressing that has the advantage of remaining in place for three to seven days, resulting in less interference with wound healing, is hydrocolloid dressing. Hydrocolloid dressings are made of a gel-like substance that forms a moist environment around the wound, promoting healing. They have an adhesive backing that adheres to the skin and can stay in place for several days, protecting the wound from external contaminants.
