What is the primary cause of Buerger’s disease, also known as thromboangiitis obliterans?

Choice A reason: Avoiding cold temperatures prevents vasospasm in Buerger’s disease but is secondary to tobacco cessation, the primary driver of disease progression. Cold exacerbates symptoms, but smoking causes the underlying inflammation and thrombosis, making this a less critical initial focus for teaching.

Choice B reason: Meticulous hygiene prevents infection in ischemic tissues but does not address the primary cause of Buerger’s disease progression, which is tobacco use. Hygiene is supportive but secondary, making this an incorrect initial focus compared to eliminating the disease’s main trigger.

Choice C reason: A low-saturated fat diet reduces atherosclerosis risk but is not the primary intervention for Buerger’s disease, which is driven by tobacco-induced inflammation and thrombosis. While beneficial for cardiovascular health, it is secondary to smoking cessation, making this an incorrect initial teaching focus.

Choice D reason: Abstaining from tobacco is the primary intervention for Buerger’s disease, as smoking causes inflammatory thrombosis, leading to vessel occlusion and ischemia. Cessation halts disease progression, reducing pain and tissue damage, making this the nurse’s initial focus to effectively manage and prevent worsening of the condition.

Choice A reason: Aerobic exercise for 30 minutes most days (150 minutes weekly) lowers blood pressure by improving vascular function and reducing cardiac workload. This is a correct recommendation, as it aligns with hypertension guidelines, promoting cardiovascular health in a 55-year-old patient.

Choice B reason: Limiting alcohol to one drink per day reduces blood pressure, as excessive alcohol raises it by increasing vascular resistance. This is a correct recommendation, supporting hypertension management by minimizing alcohol’s adverse effects on cardiovascular function in the patient.

Choice C reason: A diet high in saturated fats increases cholesterol and blood pressure, worsening hypertension. Low-saturated-fat diets, like DASH, are recommended, making this incorrect, as the nurse should teach reducing saturated fats to improve cardiovascular outcomes in hypertension.

Choice D reason: Losing weight if overweight reduces blood pressure by decreasing vascular resistance and cardiac strain. This is a correct recommendation, as weight loss is a key lifestyle change for hypertension management, improving overall cardiovascular health in the patient.

Choice E reason: Increasing processed food intake is incorrect, as these foods are high in sodium, raising blood pressure. A low-sodium diet is recommended for hypertension, making this an incorrect choice, as the nurse should teach avoiding processed foods to control blood pressure.
