When is healing by primary intention expected?
a. When the wound is left open and is allowed to heal
b. When a surgical wound is left open for 3 to 5 days
c. When connective tissue development is evident
d. When the edges of a clean incision remain close together
D
Healing by primary intention occurs when the edges of a clean surgical incision remain close together. The wound heals quickly, and tissue loss is minimal or absent. The skin cells quickly regenerate, and the capillary walls stretch across under the suture line to form a smooth surface as they join. Wounds that are left open and are allowed to heal by scar formation are classified as healing by secondary intention. Connective tissue development is evident during healing by secondary intention. Healing by tertiary intention occurs when surgical wounds are not closed immediately but are left open for 3 to 5 days to allow edema or infection to diminish.
