Which of the following statements made by a client diagnosed with HIV demonstrates an understanding of the teaching?

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.

Choice A reason: Inflammation is not an example of a client's primary defense to infection. Inflammation is a secondary defense to infection, which is activated after the primary defense has been breached. Inflammation is a complex process that involves 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 exudate. Inflammation aims to contain, neutralize, and eliminate the infectious agent and to repair the damaged tissue.

Choice B reason: Fever is not an example of a client's primary defense to infection. Fever is a secondary defense to infection, which is activated after the primary defense has been breached. Fever is an elevation of the body temperature above the normal range, which is usually 36.5 to 37.5 degrees Celsius or 97.7 to 99.5 degrees Fahrenheit. Fever is a systemic response to infection that is regulated by the hypothalamus, which is the part of the brain that controls the body's thermostat. Fever enhances the immune system's activity and inhibits the growth of some pathogens.

Choice C reason: Phagocytosis is not an example of a client's primary defense to infection. Phagocytosis is a secondary defense to infection, which is activated after the primary defense has been breached. Phagocytosis is a process that involves the engulfment and destruction of foreign particles, such as bacteria, by specialized cells, such as macrophages and neutrophils. Phagocytosis is a type of cellular immunity that eliminates the infectious agent and prevents its spread.

Choice D reason: Intact skin is an example of a client's primary defense to infection. Intact skin is the first and most important line of defense against infection, as it forms a physical barrier that prevents the entry of pathogens into the body. Intact skin also has chemical and biological properties that resist infection, such as the acidic pH, the secretion of sebum and sweat, and the presence of normal flora. Intact skin protects the underlying tissues and organs from infection and injury.
