Question 1
A 58-year-old male arrives at a rural community hospital in Buenos Aires Province with severe retrosternal crushing chest pain of 2 hours duration, diaphoresis, and nausea. An immediate 12-lead ECG reveals 3 mm ST-segment elevation in leads V1 through V4. The local center lacks a cardiac catheterization laboratory, and the expected transfer time to the nearest percutaneous coronary intervention (PCI) center is 150 minutes. The patient has no contraindications to anticoagulation or thrombolysis. What is the MOST appropriate next reperfusion strategy?
Correct Answer:
Immediate intravenous fibrinolytic therapy (e.g., tenecteplase or alteplase) administered within 30 minutes of arrival
Question 2
A 64-year-old male with ischemic cardiomyopathy and heart failure with reduced ejection fraction (LVEF 30%, NYHA Functional Class II) presents for follow-up. He is currently asymptomatic on enalapril 10 mg twice daily and bisoprolol 10 mg daily. His blood pressure is 118/72 mmHg, heart rate is 64 bpm, serum potassium is 4.3 mEq/L, and estimated GFR is 68 mL/min/1.73 m2. To reduce cardiovascular mortality and heart failure hospitalizations according to guideline-directed medical therapy (GDMT), which medication should be added next?
Correct Answer:
A mineralocorticoid receptor antagonist (e.g., Spironolactone 25 mg daily) and an SGLT2 inhibitor (e.g., Empagliflozin 10 mg daily)
Question 3
A 72-year-old female with a history of essential hypertension and type 2 diabetes mellitus presents to the outpatient clinic for routine evaluation. A 12-lead ECG reveals irregularly irregular narrow-complex tachycardia without distinct P waves at a rate of 98 bpm, confirming newly diagnosed non-valvular atrial fibrillation. Echocardiogram shows mild left atrial enlargement with preserved LVEF (55%). She has no history of stroke, TIA, or bleeding. What is her CHA2DS2-VASc score, and what is the recommended stroke prevention strategy?
Correct Answer:
CHA2DS2-VASc score = 4; initiate oral anticoagulation with a Direct Oral Anticoagulant (DOAC, e.g., Apixaban or Rivaroxaban) or Warfarin
Question 4
A 34-year-old woman is evaluated for treatment-resistant hypertension. Despite adherence to a three-drug regimen including amlodipine 10 mg, valsartan 160 mg, and hydrochlorothiazide 25 mg daily, her office blood pressure remains 168/104 mmHg. Routine laboratory testing reveals serum potassium 2.9 mEq/L, sodium 144 mEq/L, and serum bicarbonate 31 mEq/L. She is not taking licorice or laxatives. What is the MOST appropriate initial screening test for the suspected secondary etiology?
Correct Answer:
Morning plasma aldosterone-to-renin ratio (ARR)
Question 5
A 68-year-old male is brought to the emergency department in Rosario with a 3-day history of high fever, chills, pleuritic right-sided chest pain, and rust-colored sputum. On examination, he is disoriented to time and place. Vital signs: BP 94/58 mmHg, HR 108 bpm, RR 32 breaths/min, temperature 38.9 C, and SpO2 90% on room air. Chest examination reveals right lower lobe bronchial breath sounds and dullness to percussion. Serum urea is 56 mg/dL (BUN 26 mg/dL). Chest radiograph confirms right lower lobe consolidation. Based on the CURB-65 score and Argentine consensus guidelines for Community-Acquired Pneumonia (CAP), what is the appropriate management setting and initial empiric antibiotic regimen?
Correct Answer:
Hospital admission with intensive-care assessment given the high severity score; intravenous Ampicillin/Sulbactam plus Clarithromycin (or Ceftriaxone plus Azithromycin)
