What is the primary mechanism of action of spironolactone?
💡 EXPLANATION:
Spironolactone is a potassium sparing diuretic that competitively antagonizes aldosterone receptors in the distal nephron, reducing sodium reabsorption and potassium excretion.

A 55M with resistant hypertension, carotid bruits, and peripheral artery disease has hypokalemia and elevated plasma renin activity. These findings are most consistent with which condition?
💡 EXPLANATION:
Widespread atherosclerosis with resistant hypertension and high renin levels suggests renal artery stenosis causing renovascular hypertension. Primary aldosteronism typically suppresses renin.

The underlying pathophysiology of iron deficiency anemia involves:
💡 EXPLANATION:
Iron is essential for heme synthesis. Deficiency leads to reduced hemoglobin production and microcytic hypochromic red blood cells.

A stable 30-year-old woman with pain and bleeding at 8 weeks amenorrhea has ultrasound evidence of a right adnexal mass and no intrauterine pregnancy. Beta hCG is 1200. What is the most appropriate management?
💡 EXPLANATION:
This is a confirmed ectopic pregnancy meeting criteria for medical management with methotrexate due to hemodynamic stability, low beta hCG level, and small adnexal mass.

A patient with Graves disease develops a subtle high frequency tremor of the outstretched hands. This finding represents which complication?
💡 EXPLANATION:
Hyperthyroidism produces an adrenergic state leading to a high frequency low amplitude fine tremor, best seen with hands outstretched.

A patient with an inferior STEMI develops hypotension after nitrates with clear lung fields. What is the most likely cause?
💡 EXPLANATION:
Inferior STEMI may involve the right ventricle. Nitrates reduce preload and can precipitate hypotension in right ventricular infarction. Clear lungs argue against left ventricular failure.
