Which parameter is elevated in a patient with adrenal insufficiency?

Explanation:
In adrenal insufficiency, lack of aldosterone reduces potassium excretion in the distal nephron. Aldosterone normally promotes sodium reabsorption and potassium excretion; without it, potassium builds up in the blood, causing hyperkalemia. Sodium tends to be low due to decreased reabsorption, and calcium or magnesium are not typically elevated in this condition. So the elevated parameter you’d expect is potassium.
