Which of the following is a common cardiovascular complication associated with kidney failure?

A. Hypertension: Hypertension is a frequent cardiovascular complication of kidney failure. Impaired renal function leads to sodium and fluid retention as well as activation of the renin-angiotensin-aldosterone system, all of which contribute to elevated blood pressure and increased cardiac workload. B. Osteoporosis: Osteoporosis is a complication more closely associated with mineral and bone disorders in chronic kidney disease due to altered calcium and phosphate balance, but it is not considered a cardiovascular complication. C. Atherosclerosis: Atherosclerosis can occur in patients with kidney failure, especially due to dyslipidemia and chronic inflammation, but hypertension is more directly and commonly linked as the primary cardiovascular complication. D. Respiratory depression: Respiratory depression is not a cardiovascular complication. It may occur as a side effect of medications such as opioids or due to severe acidosis, but it is unrelated to the cardiovascular impact of kidney failure.
