Question

A PCT is caring for a patient who has a large wound on the upper thigh that is draining purulent fluid. The technician should identify that this wound will most likely heal by which of the following processes?

Answer 1

After the formation of a blood clot, the next response in the wound-healing process is the formation of granulation tissue, which involves the growth of new blood vessels and replacement of collagen and extracellular material lost by the injury.

Step-by-step explanation:

After containment of an injury, the tissue repair phase starts with removal of toxins and waste products. Clotting (coagulation) reduces blood loss from damaged blood vessels and forms a network of fibrin proteins that trap blood cells and bind the edges of the wound together. A scab forms when the clot dries, reducing the risk of infection. Sometimes a mixture of dead leukocytes and fluid called pus accumulates in the wound. As healing progresses, fibroblasts from the surrounding connective tissues replace the collagen and extracellular material lost by the injury. Angiogenesis, the growth of new blood vessels, results in vascularization of the new tissue known as granulation tissue. The clot retracts pulling the edges of the wound together, and it slowly dissolves as the tissue is repaired. When a large amount of granulation tissue forms and capillaries disappear, a pale scar is often visible in the healed area.
