A nurse is discussing the substance that mediates arteriolar remodeling in hypertension.
Which substance is the nurse describing?

Choice A rationale:

The term the nurse should use to describe the finding of pain on ambulation in a patient with peripheral artery disease is "intermittent claudication.”. Intermittent claudication is a classic symptom of peripheral artery disease and is characterized by muscle pain or cramping in the legs during physical activity, such as walking, which improves with rest. This choice is correct because it accurately describes the symptom associated with the condition and helps in effective communication with both the healthcare team and the patient.

Choice B rationale:

Deep vein thrombosis (DVT) is a different vascular condition that involves the formation of blood clots in deep veins, often in the legs. While DVT can also cause leg pain and swelling, it is not the appropriate term to describe the pain on ambulation in a patient with peripheral artery disease. Using this term would lead to a misunderstanding of the patient's condition, so it is not the correct choice.

Choice C rationale:

Thromboangiitis obliterans, also known as Buerger's disease, is a rare inflammatory condition that primarily affects the blood vessels in the arms and legs. While it can cause pain and other symptoms, it is not the term to describe the pain on ambulation in a patient with peripheral artery disease. Using this term would be misleading and not reflective of the patient's condition.

Choice D rationale:

Venous stasis ulcer is a term used to describe open sores or ulcers that develop on the legs due to chronic venous insufficiency. It is not the appropriate term to describe the pain on ambulation in a patient with peripheral artery disease. Using this term would not accurately convey the patient's symptoms, so it is not the correct choice.

Choice A rationale:

Aneurysms Aneurysms are not typically associated with chronic orthostatic hypotension. Aneurysms involve the weakening and ballooning of blood vessels, which can lead to life-threatening complications like rupture or dissection. However, they are not directly related to orthostatic hypotension.

Choice B rationale:

Heart failure Heart failure is a condition in which the heart cannot pump blood effectively, leading to symptoms like fluid retention, shortness of breath, and fatigue. While heart failure can cause orthostatic hypotension, it is not a complication that an older adult patient with chronic orthostatic hypotension should be primarily monitored for. Instead, the focus should be on addressing orthostatic intolerance and the risk of falls.

Choice C rationale:

Falls Chronic orthostatic hypotension is characterized by a drop in blood pressure upon standing, which can lead to dizziness, fainting, and falls. Monitoring for falls is crucial in older adults with this condition to prevent injuries and complications associated with falling. This is the correct choice because it directly addresses the potential risks associated with orthostatic hypotension.

Choice D rationale:

Atherosclerosis Atherosclerosis is a condition characterized by the buildup of fatty deposits in the arteries, which can lead to reduced blood flow to various organs. While atherosclerosis can contribute to cardiovascular issues, it is not the primary concern for an older adult with chronic orthostatic hypotension. The immediate concern is the risk of falls and related injuries.
