1A 58-year-old man presents to the emergency department in a provincial hospital in Buenos Aires with 90 minutes of crushing retrosternal chest pain radiating to his left arm and jaw. An immediate 12-lead electrocardiogram (ECG) reveals 3 mm ST-segment elevation in leads V1–V4. The nearest facility with a cardiac catheterization laboratory capable of primary percutaneous coronary intervention (PCI) is 3 hours away. Blood pressure is 135/85 mmHg, heart rate is 82 bpm, and oxygen saturation is 97% on room air. There are no contraindications to thrombolysis. According to Argentine and international acute coronary syndrome guidelines, what is the most appropriate next step in management?

A.Immediate administration of systemic intravenous fibrinolytic therapy (e.g., tenecteplase or alteplase) along with dual antiplatelet therapy and anticoagulation

B.Immediate transfer for primary PCI regardless of the expected transfer delay because PCI is always superior to fibrinolysis

C.Administration of sublingual nitrates and oral beta-blockers alone while awaiting serial cardiac troponin results

D.Emergency coronary artery bypass grafting (CABG) as first-line revascularization for anterior STEMI

Explanation: In patients presenting with ST-elevation myocardial infarction (STEMI) within 12 hours of symptom onset, primary PCI is the preferred reperfusion strategy only if it can be performed within 120 minutes of first medical contact. When the anticipated delay to primary PCI exceeds 120 minutes (in this case, transfer takes 3 hours), immediate intravenous fibrinolytic therapy should be administered within 10 minutes of diagnosis in the absence of contraindications, accompanied by dual antiplatelet therapy (aspirin plus clopidogrel) and anticoagulation (enoxaparin or unfractionated heparin).

2A 67-year-old woman with a history of ischemic cardiomyopathy (left ventricular ejection fraction 30%) presents to the emergency service with severe dyspnea, orthopnea, and pink frothy sputum. Physical examination reveals blood pressure 180/100 mmHg, heart rate 110 bpm, respiratory rate 32 breaths/min, oxygen saturation 84% on room air, bilateral pulmonary crackles extending to the upper lung fields, and jugular venous distension. What is the most appropriate immediate therapeutic combination?

A.High-dose intravenous beta-blocker (metoprolol) bolus and rapid isotonic crystalloid infusion (2000 mL normal saline)

B.Intravenous furosemide, sublingual/intravenous nitroglycerin, and non-invasive positive pressure ventilation (CPAP/BiPAP)

C.Immediate endotracheal intubation, intravenous dopamine infusion, and low-dose spironolactone

D.Intravenous digoxin bolus, oral enalapril, and continuous loop diuretics via subcutaneous route

Explanation: This patient is presenting with acute decompensated heart failure and hypertensive acute pulmonary edema. First-line emergency management includes non-invasive positive pressure ventilation (CPAP or BiPAP) to reduce work of breathing and improve oxygenation, intravenous loop diuretics (furosemide) to reduce preload, and intravenous vasodilators (nitroglycerin or nitroprusside) to rapidly reduce afterload and systemic vascular resistance in hypertensive presentations.

3A 52-year-old man presents to the emergency room with a blood pressure reading of 210/120 mmHg. He reports a mild generalized tension headache but denies chest pain, shortness of breath, visual changes, or focal neurological deficits. Fundoscopic examination is normal without papilledema or flame hemorrhages. Serum creatinine, electrolytes, and urinalysis are within normal limits. An ECG shows voltage criteria for left ventricular hypertrophy without acute ischemic changes. What is the most appropriate management for this patient?

A.Diagnose hypertensive emergency and administer intravenous sodium nitroprusside to lower mean arterial pressure by 50% in the first hour

B.Administer sublingual nifedipine capsules immediately to rapidly normalize blood pressure to < 120/80 mmHg

C.Diagnose hypertensive urgency and initiate or adjust oral antihypertensive medication with planned outpatient follow-up within 24 to 72 hours

D.Admit the patient to the intensive care unit for continuous intravenous labetalol infusion and arterial line placement

Explanation: Hypertensive crisis without evidence of acute target organ damage (e.g., encephalopathy, acute pulmonary edema, acute aortic dissection, acute renal failure, or ACS) is defined as hypertensive urgency. These patients should be managed with oral antihypertensive agents (e.g., ACE inhibitors, ARBs, calcium channel blockers) to lower blood pressure gradually over 24 to 48 hours, followed by outpatient monitoring, avoiding precipitous drops in perfusion pressure.

4A 72-year-old man with a history of hypertension and type 2 diabetes mellitus presents for a routine check-up. He is asymptomatic, but physical examination reveals an irregularly irregular pulse at 88 bpm. An ECG confirms atrial fibrillation. Transthoracic echocardiogram shows normal left ventricular function and mild left atrial enlargement without valvular heart disease. His CHA2DS2-VASc score is calculated as 3 (Age 65-74 = 1, Hypertension = 1, Diabetes = 1). According to clinical guidelines, what is the best strategy for stroke prevention in this patient?

A.Dual antiplatelet therapy with aspirin 100 mg daily plus clopidogrel 75 mg daily

B.Aspirin 325 mg daily alone as monotherapy

C.No antithrombotic therapy is indicated because the patient is entirely asymptomatic and normofrequent

D.Oral anticoagulation with a direct oral anticoagulant (DOAC, e.g., apixaban, dabigatran, or rivaroxaban) or a vitamin K antagonist (acenocoumarol/warfarin)

Explanation: In non-valvular atrial fibrillation, stroke risk is stratified using the CHA2DS2-VASc score. In men with a score >= 2 (or women >= 3), oral anticoagulation is strongly recommended to reduce the risk of thromboembolic stroke. Direct oral anticoagulants (DOACs) or vitamin K antagonists (such as acenocoumarol, the standard VKA in Argentina, or warfarin) are effective; DOACs are generally preferred over VKAs due to lower rates of intracranial hemorrhage.

5A 70-year-old woman is brought to the emergency department with a 3-day history of productive cough with rust-colored sputum, right-sided pleuritic chest pain, and high fever (38.8°C). Physical examination reveals confusion (disoriented to time and place), respiratory rate of 34 breaths/min, blood pressure of 85/55 mmHg, and heart rate of 105 bpm. Chest radiography confirms right lower lobe consolidation. Laboratory testing reveals blood urea nitrogen (BUN) of 28 mg/dL (urea 60 mg/dL). What is her CURB-65 score and the recommended site of care?

A.CURB-65 score of 5; requires urgent hospital admission with consideration for intensive care unit (ICU) monitoring

B.CURB-65 score of 1; suitable for outpatient oral antibiotic treatment

C.CURB-65 score of 2; requires brief observation in the emergency department and same-day discharge

D.CURB-65 score of 0; indicates low-risk pneumonia manageable with symptomatic home therapy

Explanation: The CURB-65 score assigns 1 point for each of: Confusion, Urea > 7 mmol/L (BUN > 19 mg/dL), Respiratory rate >= 30/min, Blood pressure < 90 mmHg systolic or <= 60 mmHg diastolic, and Age >= 65 years. This patient meets all five criteria — confusion (disoriented to time and place), BUN 28 mg/dL, respiratory rate 34/min, blood pressure 85/55 mmHg, and age 70 — giving the maximum score of 5. A score of 3 to 5 indicates severe community-acquired pneumonia requiring immediate hospitalization, and scores of 4–5 carry a 30-day mortality above 40%, making ICU assessment strongly indicated.

6A 64-year-old man with a 40 pack-year smoking history and severe COPD (GOLD Stage 3) presents with a 4-day worsening of dyspnea, increased sputum volume, and sputum purulence (Anthonisen Type 1 exacerbation). Physical examination shows tachypnea (26 breaths/min), diffuse expiratory wheezing, and an oxygen saturation of 88% on room air. Arterial blood gas shows pH 7.34, PaCO2 50 mmHg, PaO2 56 mmHg, and HCO3 26 mEq/L. In addition to controlled supplemental oxygen therapy (target SpO2 88–92%) and inhaled short-acting bronchodilators (salbutamol + ipratropium), what pharmacotherapy is indicated according to Argentine and GOLD guidelines?

A.High-dose intravenous methylprednisolone for 21 days and immediate empiric triple antifungal therapy

B.A 5-day course of systemic oral corticosteroids (e.g., prednisone 40 mg daily) and an oral antibiotic (e.g., amoxicillin-clavulanate or azithromycin)

C.Inhaled fluticasone alone without oral steroids or antibiotics

D.Oral theophylline and prophylactic low-dose aspirin without bronchodilators

Explanation: In acute exacerbations of COPD with all three cardinal symptoms (increased dyspnea, increased sputum volume, and increased sputum purulence—Anthonisen Type 1), evidence-based guidelines recommend: 1) Controlled oxygen to maintain SpO2 88-92% (avoiding hypercapnic respiratory arrest); 2) Inhaled short-acting beta-2 agonists plus anticholinergics; 3) A short course of systemic corticosteroids (prednisone 40 mg daily for 5 days) to shorten recovery time and reduce treatment failure; and 4) Empiric antibiotics targeting H. influenzae, S. pneumoniae, and M. catarrhalis (e.g., amoxicillin-clavulanate, azithromycin, or clarithromycin) for 5 to 7 days.

7A 24-year-old woman with known moderate persistent asthma presents to the emergency room with severe acute bronchospasm. She can only speak in single words, has marked intercostal retractions, a respiratory rate of 36 breaths/min, pulse rate of 125 bpm, and a peak expiratory flow (PEF) of 35% of predicted. After receiving 3 continuous nebulizations of salbutamol (albuterol) with ipratropium bromide and 200 mg intravenous hydrocortisone over the first hour, she remains in severe respiratory distress with persistent wheezing and PEF 40%. What is the most appropriate next pharmacologic adjunct?

A.Subcutaneous epinephrine 1 mg rapid bolus every 5 minutes

B.Intravenous aminophylline continuous infusion without monitoring

C.Intravenous magnesium sulfate (2 g infused over 20 minutes)

D.Oral montelukast chewable tablets as monotherapy

Explanation: Intravenous magnesium sulfate (2 g single dose IV over 20 minutes) is recommended as an effective adjunct in patients with severe acute asthma exacerbations (PEF < 50% predicted or lack of response to initial intensive inhaled bronchodilators and systemic steroids). It acts as a smooth muscle relaxant by inhibiting calcium influx, reducing hospital admission rates in severe acute asthma.

8A 45-year-old woman who underwent total abdominal hysterectomy 10 days ago presents with sudden-onset pleuritic chest pain, dyspnea, and hemoptysis. Physical exam reveals heart rate 112 bpm, blood pressure 125/80 mmHg, respiratory rate 24 breaths/min, and oxygen saturation 93% on room air. Her left lower extremity is swollen, warm, and tender to palpation. Her Wells score for pulmonary embolism (PE) is 7.5 (high probability). What is the definitive diagnostic imaging modality of choice?

A.Qualitative plasma D-dimer assay

B.Standard posterior-anterior and lateral chest radiography

C.Transthoracic echocardiogram alone without vascular imaging

D.Computed tomography pulmonary angiography (CTPA / Angio-TC de tórax)

Explanation: In hemodynamically stable patients with a high clinical pre-test probability of pulmonary embolism (Wells score > 6 or simplified Wells >= 4), Computed Tomography Pulmonary Angiography (CTPA / Angio-TC de tórax) is the reference standard diagnostic imaging of choice. D-dimer testing is not indicated in high-probability patients because a negative D-dimer cannot safely rule out PE in this setting.

9A 56-year-old man with newly diagnosed type 2 diabetes mellitus (HbA1c 8.2%) has a history of stage 3a chronic kidney disease (estimated glomerular filtration rate [eGFR] 52 mL/min/1.73m²) and established atherosclerotic cardiovascular disease (prior myocardial infarction 3 years ago). His BMI is 31 kg/m². According to Argentine Ministry of Health and international diabetes guidelines (ADA/KDIGO), what is the optimal initial combination pharmacotherapy?

A.Metformin plus an SGLT2 inhibitor (e.g., empagliflozin or dapagliflozin) or GLP-1 receptor agonist

B.Glibenclamide monotherapy at maximum dose

C.Rapid-acting insulin analogue sliding scale before meals with no oral agents

D.Pioglitazone combined with high-dose acarbose

Explanation: In patients with type 2 diabetes and established atherosclerotic cardiovascular disease or chronic kidney disease, metformin is the foundational first-line agent (safe when eGFR >= 30 mL/min/1.73m²), combined with an SGLT2 inhibitor (e.g., empagliflozin, dapagliflozin) or a GLP-1 receptor agonist with proven cardiovascular and renal benefits, independent of baseline HbA1c.

10A 21-year-old woman with type 1 diabetes mellitus is admitted to the emergency ward with nausea, vomiting, abdominal pain, and Kussmaul breathing. Laboratory results show: capillary blood glucose 480 mg/dL, arterial pH 7.15, serum bicarbonate 9 mEq/L, anion gap 24 mEq/L, urine ketones strongly positive (++++), and serum potassium 3.1 mEq/L. What is the essential first step before initiating intravenous regular insulin therapy?

A.Administer an immediate intravenous bolus of regular insulin at 0.4 units/kg followed by sodium bicarbonate

B.Infuse intravenous isotonic saline (0.9% NaCl) and replete potassium to > 3.3 mEq/L before starting insulin

C.Withhold all fluids and administer intravenous potassium chloride as a direct rapid push

D.Administer subcutaneous long-acting insulin degludec and delay all IV hydration

Explanation: In the management of diabetic ketoacidosis (DKA), vigorous fluid resuscitation with 0.9% NaCl is the priority. However, if baseline serum potassium is below 3.3 mEq/L, intravenous insulin MUST be withheld while potassium is actively replaced (20–30 mEq/hour in IV fluids) until serum potassium rises above 3.3 mEq/L. Initiating insulin in a hypokalemic patient drives potassium intracellularly, triggering fatal cardiac arrhythmias or respiratory muscle paralysis.

About the ERES Bonaerense Medicina Exam

The Examen de Residencias del Sistema de Salud Bonaerense (ERES Bonaerense) — Medicina is the official competitive entrance examination for medical residency training across provincial and municipal hospitals and primary care centers in Buenos Aires Province, Argentina. Governed by the Escuela de Gobierno en Salud Floreal Ferrara under the Reglamento del ERES Bonaerense 2026 and Ley Provincial 10.471, it tests clinical competence across internal medicine, pediatrics, general surgery, obstetrics and gynecology, and public health. Language note: the ERES Bonaerense is set and sat entirely in Spanish against the official PBA temario. These practice questions are an English-language multiple-choice study adaptation built from that official scope — they are not an official translation, not published or endorsed by the Ministerio de Salud de la Provincia de Buenos Aires, and not a simulation of the exam's Spanish-language testing environment. Official exam names, Argentine statute numbers, and local clinical terms are kept in Spanish so you can match them to the real bibliography.

Assessment

Frequently Asked Questions

What is the Examen de Residencias Bonaerenses (ERES Bonaerense)?

The ERES Bonaerense is the competitive entrance examination organized by the Escuela de Gobierno en Salud Floreal Ferrara under the Ministerio de Salud de la Provincia de Buenos Aires to select medical graduates for residency positions in provincial and municipal hospitals throughout Buenos Aires Province.

How is the exam structured and administered?

Article 9 of the Reglamento del ERES Bonaerense 2026 sets the paper at exactly 100 single-best-answer multiple-choice questions worth 1 point each, sat in person on optical answer sheets at designated provincial sedes. The reglamento does not publish an exam duration, so do not assume one — check the convocatoria for the sitting you are entered for.

How is the final merit ranking (Orden de Mérito) determined?

Article 11 of the Reglamento del ERES Bonaerense 2026 sets the formula for básicas as (E) + (P x 0,5): the 100-point written score plus half of the university GPA including aplazos on a 0-10 scale. Ties break first on the higher exam score, then the higher GPA, then a draw. Posbásicas use (E x 0,5) + A, where A is up to 5 points of assessed antecedentes.

What core subject areas and laws are tested?

The Escuela Floreal Ferrara publishes an official bibliography per specialty and discipline, but it does not publish percentage weightings for the Medicina paper. This bank therefore covers the core clinical areas drawn from that bibliography — internal medicine, pediatrics, general surgery, tocoginecología, and public health with provincial and national health law (Ley 10.471, Ley 26.529, Ley 26.657, Ley 27.610, SNVS/SISA reporting) — and the question counts shown are this bank's own distribution, not an official blueprint.

How much does it cost to register for the ERES Bonaerense?

The Reglamento del ERES Bonaerense 2026 does not set any arancel or examination fee, and none is published on the Escuela Floreal Ferrara residency portal. Confirm the current requirements on the official portal before registering.

Is this practice bank in Spanish like the real exam?

No. The official ERES Bonaerense is set in Spanish. This bank is an English-language multiple-choice study adaptation derived from the official Floreal Ferrara temario, designed for candidates preparing in English while retaining Argentine statutory numbers and local clinical terminology in Spanish.
