Which outcome is most likely in an individual with hypertension whose kidneys exhibit increased aldosterone production but normal angiotensin II levels?

💡 Explanation

Increased aldosterone promotes sodium and water retention in the kidneys, because it acts on the distal tubules and collecting ducts. This increases blood volume and, therefore, blood pressure, rather than the opposite, due to a failure in the mineralocorticoid receptor regulation by other hormones.
