The nurse is performing discharge teaching for a Type 2 diabetic client on insulin glargine. The nurse is aware that the teaching has been effective when the client states:

Choice A Reason
Acute compartment syndrome occurs when bleeding or swelling within an enclosed bundle of muscles – known as a muscle compartment – leads to increased pressure. This pressure can impede blood flow to the body tissue and destroy function. The fascia, which is a tough layer of fibrous tissue, does not stretch easily, so any swelling or bleeding can quickly lead to increased pressure.

Choice B Reason
While displaced bones can compress nerves and vessels, this is not the primary mechanism of acute compartment syndrome. Displaced bones are more likely to cause direct injury or impingement, but compartment syndrome specifically refers to the pressure build-up within a muscle compartment that affects circulation and tissue viability.

Choice C Reason
Interruption of blood supply to the bone is a serious concern and can lead to conditions such as avascular necrosis. However, in the context of acute compartment syndrome, the primary issue is the pressure within the muscle compartment rather than direct disruption of blood supply to the bone.

Choice D Reason
Compression of muscle tissue can restrict blood flow to the area, which is a part of the pathophysiology of compartment syndrome. However, the compression is a result of increased pressure within the compartment, not the primary cause. The increased pressure is due to bleeding and swelling, which is why choice A is the most accurate description.

Choice A Reason
Increased urine output is not a direct indicator of the effectiveness of nitroglycerin for angina pectoris. Nitroglycerin is a vasodilator used primarily to relieve chest pain by improving blood flow to the heart muscle, not to influence urine production.

Choice B Reason
Asking the client if their chest pain has been relieved is the most direct method of evaluating the effectiveness of nitroglycerin. Relief of chest pain indicates that the medication is working as intended, reducing the ischemia that causes angina.

Choice C Reason
While taking the client's blood pressure is important, especially since nitroglycerin can cause hypotension, it is not the primary method for evaluating the effectiveness of the medication in relieving angina. Blood pressure measurements are more of a safety check to monitor for adverse effects.

Choice D Reason
Ambulation and assessing for the absence of dyspnea can be part of an overall evaluation of the client's cardiovascular status, but they are not specific to evaluating the effectiveness of nitroglycerin for angina relief. Dyspnea may be a symptom of heart failure or other conditions, not specifically angina pectoris.
