The nurse is caring for a patient in the burn unit.The nurse recalls that this type of wound heals by which process?

A) Tertiary intention.
B) Secondary intention.
C) Partial-thickness repair.
D) Primary intention.

A wound involving loss of tissue such as a burn or a pressure injury or laceration heals by secondary intention.The wound is left open until it becomes filled with scar tissue.It takes longer for a wound to heal by secondary intention;thus the chance of infection is greater.A clean surgical incision is an example of a wound with little loss of tissue that heals by primary intention.The skin edges are approximated or closed,and the risk for infection is low.Partial-thickness repair are done on partial-thickness wounds that are shallow,involving loss of the epidermis and maybe partial loss of the dermis.These wounds heal by regeneration because the epidermis regenerates.In tertiary intention,a wound is left open for several days,and then the wound edges are approximated;wound closure is delayed until the risk of infection is resolved.
