A patient with adrenal tumor has symptoms of hypertension, edema, hypernatremia and hypokalemia. Which drug would be most likely to prescribe to antagonize the renal and systemic side effects of the hormone excess?
Correct Answer: A
Rationale: The correct answer is A: Spironolactone. Spironolactone is a potassium-sparing diuretic that works by antagonizing aldosterone, which is responsible for the symptoms of hypertension, edema, hypernatremia, and hypokalemia seen in adrenal tumor. By blocking aldosterone receptors, spironolactone helps to reduce sodium reabsorption and potassium excretion, thus counteracting the hormonal effects.
Bumetanide (choice B) and Furosemide (choice C) are loop diuretics that primarily work by inhibiting sodium reabsorption in the loop of Henle and are unlikely to be as effective in this scenario. Acetazolamide (choice D) is a carbonic anhydrase inhibitor that works in the proximal tubule and is not indicated for the specific hormonal effects seen in this case.
