A nurse is providing education to a client who has a newly diagnosed abdominal aortic aneurysm (AAA). Which of the following statements should the nurse include in the teaching?
An abdominal aortic aneurysm is commonly found in the suprarenal aorta.
An abdominal aortic aneurysm occurs as a result of a thickened wall of the abdominal artery.
An abdominal aortic aneurysm is a dilation of the abdominal aorta greater than 30 mm in diameter.
Abdominal aortic aneurysms might rupture if blood pressure is too low.
The Correct Answer is C
A. An abdominal aortic aneurysm is commonly found in the suprarenal aorta: This statement is incorrect. Abdominal aortic aneurysms (AAAs) are most commonly found infrarenally, below the level of the renal arteries, rather than in the suprarenal region.
B. An abdominal aortic aneurysm occurs as a result of a thickened wall of the abdominal artery: This statement is incorrect. An abdominal aortic aneurysm typically occurs due to weakening of the arterial wall, rather than thickening. The weakened wall allows the arterial wall to bulge or balloon out, forming an aneurysm.
C. An abdominal aortic aneurysm is a dilation of the abdominal aorta greater than 30 mm in diameter: This statement is correct. An abdominal aortic aneurysm is defined as a localized dilation of the abdominal aorta that exceeds 50% of the normal vessel diameter, typically greater than 30 mm in diameter. This dilation occurs due to weakening of the arterial wall, which can result from various factors such as atherosclerosis, hypertension, and genetic predisposition.
D. Abdominal aortic aneurysms might rupture if blood pressure is too low: This statement is incorrect. Abdominal aortic aneurysms are more likely to rupture when blood pressure is too high, rather than too low. Hypertension increases the pressure within the weakened arterial wall, potentially leading to rupture. Therefore, controlling blood pressure is crucial in managing abdominal aortic aneurysms to reduce the risk of rupture.

Correct Answer is ["D","E"]
Explanation
A. Diabetes mellitus: An inverse association between diabetes mellitus (DM) and abdominal aortic aneurysm (AAA) risk hasbeen reported. Apart from a lower AAA prevalence among patients with vsthose without DM, there isdata showing that DM may exert a protective role on aneurysmal growth in patients with small AAAs, thus decreasing the risk of rupture. As atherosclerosis has almost the same risk factors as aneurysms, the decreased AAA prevalence in patients with DM may indicate that atherosclerosis is an associated feature and not a cause of the aneurysms.
B. Total cholesterol 170 mg/dL (less than 200 mg/dL): While elevated total cholesterol is a risk factor for cardiovascular disease, it is not specifically listed as a risk factor for abdominal aortic aneurysm (AAA). However, dyslipidemia, including elevated total cholesterol levels, can contribute to the development of atherosclerosis, which is a risk factor for AAA.
C. HDL cholesterol 65 mg/dL (male greater than 45 mg/dL; female greater than 55 mg/dL): High-density lipoprotein (HDL) cholesterol levels greater than 65 mg/dL are not listed as a risk factor for abdominal aortic aneurysm (AAA). However, low levels of HDL cholesterol are associated with an increased risk of cardiovascular disease, which may indirectly contribute to the development of AAA through the promotion of atherosclerosis.
D. Smoking cigarettes: Smoking cigarettes is a significant modifiable risk factor for abdominal aortic aneurysm (AAA). Smoking damages the walls of blood vessels, promotes inflammation, and accelerates the development of atherosclerosis, increasing the risk of AAA formation and rupture.
E. Family history of aneurysm: A family history of aneurysm, particularly abdominal aortic aneurysm (AAA), is a risk factor for developing AAA. Genetic factors can predispose individuals to the development of aneurysms, and a positive family history increases the likelihood of AAA occurrence.
Correct Answer is B
Explanation
A. "You can have 2 to 3 cups of coffee throughout the day": Caffeine consumption can exacerbate tinnitus symptoms in some individuals. Therefore, advising the client to limit caffeine intake, rather than specifying a quantity, would be more appropriate.
B. "You should practice deep breathing exercises": Deep breathing exercises and relaxation techniques can help reduce stress and anxiety, which may contribute to tinnitus symptoms. Stress management strategies can be beneficial in managing tinnitus-related distress.
C. "You can use at least 2,300 mg of sodium daily": High sodium intake may exacerbate tinnitus symptoms in some individuals. Advising the client to limit sodium intake would be more appropriate to potentially alleviate symptoms.
D. "You should avoid exercising": Regular exercise is generally beneficial for overall health and well-being, including stress reduction, which can help manage tinnitus symptoms. Therefore, advising the client to avoid exercising is not appropriate.
