What is true about antiretroviral drugs used to treat human immunodeficiency virus (HIV)?

Choice A reason: Providing the client with antipyretic therapy is not the nurse's priority. Antipyretic therapy is a treatment that lowers the body temperature and reduces fever. Fever is a common symptom of acute osteomyelitis, which is a bacterial infection of the bone and bone marrow. Antipyretic therapy may help to relieve the discomfort and inflammation caused by fever, but it does not address the underlying cause of the infection.

Choice B reason: Administering antibiotics to the client is the nurse's priority. Antibiotics are medications that kill or inhibit the growth of bacteria. Antibiotics are the main treatment for acute osteomyelitis, as they target the specific type of bacteria that is causing the infection. Antibiotics can prevent the spread of the infection to other bones or organs and reduce the risk of complications, such as chronic osteomyelitis, septic arthritis, or sepsis.

Choice C reason: Increasing the client's protein intake is not the nurse's priority. Protein intake is a nutritional factor that affects the wound healing and immune system. Protein is composed of amino acids, which are the building blocks of cells and tissues. Protein intake can enhance the repair and regeneration of the bone and the soft tissues that are damaged by the infection. Protein intake can also support the immune system's ability to fight off the infection. However, protein intake alone is not sufficient to treat acute osteomyelitis, as it does not eliminate the bacteria that are causing the infection.

Choice D reason: Teaching relaxation breathing to reduce the client's pain is not the nurse's priority. Relaxation breathing is a technique that involves deep and slow breathing that helps to relax the body and mind. Relaxation breathing can help to reduce the pain and stress that are associated with acute osteomyelitis. Pain is a common symptom of acute osteomyelitis, which is caused by the inflammation and pressure on the bone and the surrounding tissues. Relaxation breathing can help to ease the pain and improve the mood and quality of life of the client. However, relaxation breathing alone is not enough to treat acute osteomyelitis, as it does not address the source of the pain.

Choice A reason: A bone fragment has injured the nerve supply in the area is not the best response by the nurse. This may be a possible complication of a fracture, but it does not explain the mechanism of compartment syndrome. Compartment syndrome is a condition where the pressure within a closed space (such as a muscle compartment) exceeds the perfusion pressure and causes ischemia and necrosis of the tissues. A bone fragment may damage the nerve, but it does not cause increased pressure in the compartment.

Choice B reason: An injured artery causes impaired arterial perfusion through the compartment is not the best response by the nurse. This may be a possible cause of compartment syndrome, but it is not the most common one. Compartment syndrome is more often caused by venous obstruction than arterial obstruction. An injured artery may reduce the blood flow to the compartment, but it does not cause increased pressure in the compartment.

Choice C reason: Bleeding and swelling cause increased pressure in an area that cannot expand is the best response by the nurse. This is the most common cause of compartment syndrome and explains the pathophysiology of the condition. Bleeding and swelling are the result of inflammation and tissue injury that occur after a fracture. They increase the volume of fluid in the compartment, which cannot expand due to the rigid fascia that surrounds it. This leads to increased pressure in the compartment, which compresses the blood vessels, nerves, and muscles and causes ischemia and necrosis of the tissues.

Choice D reason: The fascia expands with injury, causing pressure on underlying nerves and muscles is not the best response by the nurse. This is not a correct statement, as the fascia does not expand with injury. The fascia is a tough connective tissue that encloses the muscle compartments and limits their expansion. The fascia is part of the problem, not the cause, of compartment syndrome. The fascia prevents the compartment from accommodating the increased volume of fluid and causes increased pressure in the compartment.
