The nurse is caring for a client who develops compartment syndrome from a severely fractured arm. The client asks the nurse why this can happen. What is the best response by the nurse?
A bone fragment has injured the nerve supply in the area.
An injured artery causes impaired arterial perfusion through the compartment.
Bleeding and swelling cause increased pressure in an area that cannot expand.
The fascia expands with injury, causing pressure on underlying nerves and muscles.
The Correct Answer is C
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.

Correct Answer is C
Explanation
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.
Correct Answer is C
Explanation
Choice A reason: Culturing the wound is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Culturing the wound is a procedure that involves collecting a sample of the wound drainage and sending it to the laboratory for analysis, which can help identify the type and source of infection. Culturing the wound is an important intervention, but it should be done after inspecting the wound and assessing the drainage, and with a medical order and a sterile technique.
Choice B reason: Applying topical ointment to the wound is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Applying topical ointment to the wound is a procedure that involves applying a medication or a dressing to the wound site, which can help prevent or treat infection, inflammation, or pain. Applying topical ointment to the wound is an important intervention, but it should be done after inspecting the wound and assessing the drainage, and with a medical order and a clean technique.
Choice C reason: Inspecting the wound and assessing the drainage is the nurse's priority assessment for this client, because it is the most urgent and relevant action. Inspecting the wound and assessing the drainage is a process that involves observing and measuring the wound site and the wound exudate, which can reveal the presence and severity of infection, injury, or healing. Inspecting the wound and assessing the drainage is an essential assessment, as it can guide the diagnosis, treatment, and evaluation of the client's condition.
Choice D reason: Calling the provider to initiate antibiotics is not the nurse's priority assessment for this client, because it is not the most urgent and relevant action. Calling the provider to initiate antibiotics is a communication that involves reporting the client's situation and requesting a prescription for an antimicrobial agent, which can help fight or prevent infection. Calling the provider to initiate antibiotics is an important communication, but it should be done after inspecting the wound and assessing the drainage, and with the necessary data and documentation.
