A 73-year-old patient has increased pulmonary pressure resulting in right heart failure. What could be a potential cause for the right heart to fail?

Choice A rationale
Advocating for a diet rich in saturated fats is not a recommended strategy to prevent cardiovascular disease. Saturated fats can raise the level of cholesterol in your blood and increase your risk of heart disease.
Choice B rationale
Recommending cessation of smoking is a crucial intervention to prevent cardiovascular disease. Chemicals in tobacco can damage the heart and blood vessels, leading to narrowing of the arteries (atherosclerosis), which can ultimately lead to a heart attack.
Choice C rationale
Regular blood pressure monitoring is important as high blood pressure is a significant risk factor for heart disease. Controlling blood pressure helps ensure that your heart is not working harder than it should be, which can prevent damage to your heart and arteries.
Choice D rationale
Regular cholesterol screenings are essential because high levels of cholesterol can lead to the buildup of plaques in your arteries, increasing your risk of heart disease.
Choice E rationale
Regular physical exercise helps control your weight and can reduce your chances of developing other conditions that may put a strain on your heart, such as high blood pressure, high cholesterol, and diabetes.
Choice F rationale
Suggesting no more than 5 alcoholic drinks a day is not a recommended strategy to prevent cardiovascular disease. In fact, it is advised to limit alcohol intake as excessive drinking can lead to high blood pressure, heart failure, or even stroke.

Choice A rationale
Low urine osmolarity and creatinine clearance are not the primary indicators of inadequate renal perfusion in a patient being stabilized after an acute coronary syndrome. These measures reflect the concentration of the urine and the kidney’s ability to filter waste from the blood, respectively. While they can be affected by renal perfusion, they are not the most direct or reliable indicators.
Choice B rationale
A decreasing serum blood urea nitrogen (BUN) level is not typically associated with inadequate renal perfusion. In fact, a high BUN level may indicate that the kidneys aren’t working properly. However, BUN levels can be influenced by many factors, including protein intake and liver function, so they are not the most reliable indicator of renal perfusion.
Choice C rationale
A urine output of less than 30 mL/hr is a common sign of inadequate renal perfusion. The kidneys need adequate blood flow to filter waste products from the blood and produce urine. If renal perfusion is inadequate, urine output can decrease.
Choice D rationale
A urine-specific gravity of less than 1.010 is not typically associated with inadequate renal perfusion. Specific gravity is a measure of the concentration of solutes in the urine. It can be influenced by hydration status and certain kidney disorders, but it is not a direct measure of renal perfusion.
