What are the causes of a pressure ulcer? (Select all that apply.)

Choice A reason: Inflammatory is the phase of wound healing that occurs at the time of injury and lasts about 35 days, because it is the first and immediate response to tissue damage. Inflammatory is the phase of wound healing that involves the activation of the immune system, the release of chemical mediators, the dilation of blood vessels, the increase of blood flow, the migration of white blood cells, and the formation of a clot. Inflammatory is the phase of wound healing that aims to control bleeding, prevent infection, and prepare the wound for healing.

Choice B reason: Proliferative is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather the phase of wound healing that occurs after the inflammatory phase and lasts about 23 weeks. Proliferative is the phase of wound healing that involves the growth and multiplication of new cells, the formation of granulation tissue, the synthesis of collagen, the contraction of the wound edges, and the development of epithelial tissue. Proliferative is the phase of wound healing that aims to fill the wound, restore the strength, and cover the defect.

Choice C reason: Maturation is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather the phase of wound healing that occurs after the proliferative phase and lasts about several months to years. Maturation is the phase of wound healing that involves the remodeling and reorganization of the collagen fibers, the reduction of scar tissue, the improvement of elasticity, and the restoration of function. Maturation is the phase of wound healing that aims to refine the wound, enhance the quality, and optimize the outcome.

Choice D reason: Intentional is not the phase of wound healing that occurs at the time of injury and lasts about 35 days, but rather a classification of wound healing that depends on the type and extent of tissue damage, the degree of contamination, and the method of closure. Intentional is a classification of wound healing that refers to wounds that are surgically created, have minimal tissue loss, are clean and sterile, and are closed by primary intention, which means that the wound edges are approximated with sutures, staples, or glue. Intentional is a classification of wound healing that results in faster healing, less scarring, and lower risk of infection.

Choice A reason: Eradicating the disease is not the purpose of the medications, because osteoarthritis is a chronic and progressive condition that cannot be cured by drugs. Osteoarthritis is a degenerative joint disease that causes the breakdown of cartilage and bone, leading to pain, stiffness, and reduced mobility.

Choice B reason: Turning on the immune system is not the purpose of the medications, because osteoarthritis is not an autoimmune disease that involves the immune system attacking the joints. Osteoarthritis is a mechanical disease that involves the wear and tear of the joints due to aging, injury, or overuse.

Choice C reason: Reducing pain and inflammation is the purpose of the medications, because osteoarthritis is a painful and inflammatory condition that affects the quality of life of the client. The medications for osteoarthritis include analgesics, such as acetaminophen or opioids, and antiinflammatory drugs, such as nonsteroidal antiinflammatory drugs (NSAIDs) or corticosteroids, which can relieve the symptoms and improve the function of the joints.

Choice D reason: Managing weight loss is not the purpose of the medications, because osteoarthritis is not a metabolic disease that affects the weight of the client. Osteoarthritis is a structural disease that affects the joints of the client. However, managing weight is an important factor in preventing or treating osteoarthritis, as excess weight can increase the stress and damage on the joints.
