A patient presents with increased sodium reabsorption and increased potassium excretion. Which adrenal hormone is most likely elevated?
Understand the Problem
The question is asking to identify which adrenal hormone is most likely elevated given the symptoms of increased sodium reabsorption and increased potassium excretion. This requires knowledge of the function of adrenal hormones, specifically their effects on electrolyte balance.
Answer
Aldosterone
The adrenal hormone most likely elevated is aldosterone. Aldosterone increases sodium reabsorption and potassium excretion.
Answer for screen readers
The adrenal hormone most likely elevated is aldosterone. Aldosterone increases sodium reabsorption and potassium excretion.
More Information
Aldosterone is a mineralocorticoid hormone produced by the adrenal glands. Its primary role is to regulate sodium and potassium levels in the body, which in turn affects blood pressure and fluid balance.
Tips
A common mistake is confusing aldosterone with other adrenal hormones like cortisol. Remember aldosterone specifically regulates sodium and potassium balance.
