Which failure mode becomes likely when chronic hypertension causes arterial stiffness to diminish baroreceptor sensitivity and impair regulation of aldosterone?

A)Increased natriuretic peptide secretion
B)Decreased potassium excretion rate
C)Exaggerated blood pressure fluctuations
D)Reduced renin-angiotensin activation

💡 Explanation

Exaggerated blood pressure fluctuations become likely because impaired baroreceptor sensitivity disrupts the normal negative feedback loop controlling aldosterone secretion; therefore, aldosterone levels become less responsive to changes in blood volume and pressure, rather than maintaining stable control.
