ST elevations in leads II, III, and aVF indicate an inferior MI, which is most commonly caused by occlusion of the right coronary artery.
A patient with type 2 diabetes and CKD stage 3 requires glucose-lowering therapy. Which agent is contraindicated due to risk of lactic acidosis?

Metformin is contraindicated when eGFR is below 30 mL/min due to risk of lactic acidosis from impaired renal clearance.
A 35-year-old woman presents with episodic hypertension, headache, diaphoresis, and palpitations. Plasma free metanephrines are markedly elevated. What is the most appropriate next step?
