Final Answer : C, Explanation :  Pressure injuries are full-thickness wounds that extend into the dermis and heal by scar formation because the deeper structures do not regenerate;hence the need for full-thickness repair.The full-thickness repair has three phases: inflammatory,proliferative,and remodelling.A wound heals by primary intention when wounds such as surgical wounds have little tissue loss;the skin edges are approximated or closed;and the risk for infection is low.Partial-thickness repairs 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 risk of infection is resolved.
