The nurse is providing teaching to a patient with Buerger disease. Which of the following statements by the patient would the nurse evaluate as indicating understanding about Buerger disease?

A. "Smoking cessation is important because nicotine is a vasoconstrictor.": Buerger disease is strongly associated with tobacco use, and nicotine causes vasoconstriction, which exacerbates the condition. Smoking cessation is crucial in managing and preventing progression.
B. "Adequate fluid intake is important to maintain blood pressure.": While staying hydrated is generally important, it is not specifically related to the management of Buerger disease, which is more focused on vascular health and smoking cessation.
C. "Those most affected are middle-aged women after menopause.": Buerger disease predominantly affects young male smokers, not middle-aged women.
D. "A low-fat diet is required to reduce atherosclerosis in large arteries.": Buerger disease involves inflammation and thrombosis in small and medium-sized arteries and veins, not atherosclerosis in large arteries. Therefore, a low-fat diet, while beneficial for general cardiovascular health, is not specifically targeted for Buerger disease.

A. I will walk 20 minutes every other day: This is correct. Walking is a safe, low-impact activity that promotes cardiovascular health without placing undue stress on the abdominal area, which is important for a patient with an AAA.
B. Instead of taking my car, I will ride my bike everywhere: Biking can be too strenuous and risky for someone with an AAA, as it may involve physical exertion and potential for trauma to the abdominal area.
C. I am starting back to work as a grocery store stocker next week: This job likely involves heavy lifting and significant physical activity, which is contraindicated for a patient with an AAA due to the risk of increased intra-abdominal pressure and potential aneurysm rupture.
D. I am going to continue my marathon training tomorrow: Marathon training is highly strenuous and can significantly increase blood pressure and stress on the abdominal region, posing a high risk of aneurysm rupture.
