The Mendoza Medical Residency Examination (Primer Nivel) is a 4-hour (240 minutes), 100-question written multiple-choice test conducted in person with optical answer sheets. Resolución 1193/2026 fixes the format: 100 questions with four alternatives and a single correct answer, four hours, 1 point per correct answer to a maximum of 100 points, and that result becomes the merit score for the knowledge stage of the concurso. The Ministerio de Salud y Deportes de Mendoza publishes no arancel for the contest. Mendoza releases the actual papers with official answer keys and a per-profession bibliography rather than percentage weightings, so this bank's coverage of clínica médica, pediatría, cirugía general, tocoginecología and Argentine/Mendoza health regulations (Ley 26.529, Ley 26.657, Ley 27.610, Resolución 521/26) reflects that released material rather than an official blueprint. This prep bank is authored as an English study adaptation aligned to Mendoza's released papers and official syllabus.

1A 58-year-old male presents to the emergency department with severe substernal chest pain of 90 minutes duration radiating to his left jaw. The ECG demonstrates 3 mm ST-segment elevation in leads V1–V4. The hospital has an on-site catheterization laboratory capable of performing primary percutaneous coronary intervention (PCI). What is the recommended reperfusion strategy and target door-to-balloon time?

A.Primary PCI with a target door-to-balloon time of ≤ 90 minutes

B.Immediate intravenous fibrinolytic therapy with tenecteplase within 30 minutes

C.Transfer to an intensive care unit for 24-hour unfractionated heparin infusion before angiography

D.Urgent coronary artery bypass grafting within 6 hours

Explanation: In patients presenting with ST-elevation myocardial infarction (STEMI) within 12 hours of symptom onset at a PCI-capable facility, primary PCI is the gold standard reperfusion modality. The target door-to-balloon time is ≤ 90 minutes. Fibrinolysis is reserved for situations where primary PCI cannot be performed within 120 minutes of medical contact.

2A 67-year-old female presents with fever, productive cough with rust-colored sputum, and pleuritic right-sided chest pain for 3 days. Vital signs show BP 105/65 mmHg, HR 98 bpm, RR 24/min, and oxygen saturation 94% on room air. She is alert and oriented (Glasgow Coma Scale 15). Blood urea nitrogen (BUN) is 16 mg/dL. Chest radiography confirms a right lower lobe consolidation. Based on the CURB-65 score, what is the most appropriate management setting?

A.Immediate admission to the Intensive Care Unit (ICU)

B.Outpatient treatment with oral amoxicillin or amoxicillin-clavulanate plus a macrolide

C.Inpatient admission to the general medical ward with IV dual therapy

D.Observation in the emergency department for 48 hours without antibiotics

Explanation: The CURB-65 criteria assign 1 point each for Confusion, Urea > 19 mg/dL (7 mmol/L), Respiratory rate ≥ 30/min, Blood pressure < 90/60 mmHg, and age ≥ 65 years. This patient scores 1 point solely for age ≥ 65. A CURB-65 score of 0 or 1 indicates low mortality risk (< 1.5%), making outpatient oral therapy safe and appropriate.

3A 62-year-old male with long-standing type 2 diabetes mellitus and a history of myocardial infarction 3 years ago presents for routine follow-up. His current medications include metformin 1000 mg twice daily and enalapril 10 mg daily. His HbA1c is 8.2%, eGFR is 52 mL/min/1.73 m², and urine albumin-to-creatinine ratio is 180 mg/g. Which second-line antihyperglycemic agent is most strongly indicated to reduce both cardiovascular events and progression of chronic kidney disease?

A.Sulfonylurea (e.g., glimepiride)

B.Thiazolidinedione (e.g., pioglitazone)

C.Sodium-glucose cotransporter-2 (SGLT2) inhibitor (e.g., empagliflozin or dapagliflozin)

D.Dipeptidyl peptidase-4 (DPP-4) inhibitor (e.g., sitagliptin)

Explanation: International and Argentine clinical practice guidelines recommend adding an SGLT2 inhibitor (or a GLP-1 receptor agonist with proven cardiovascular benefit) in patients with type 2 diabetes who have established atherosclerotic cardiovascular disease and/or diabetic kidney disease with albuminuria, independent of baseline HbA1c. SGLT2 inhibitors significantly reduce major adverse cardiovascular events, heart failure hospitalizations, and renal disease progression.

4A 24-year-old female with type 1 diabetes mellitus is brought to the emergency department with nausea, vomiting, diffuse abdominal pain, and deep rapid respirations (Kussmaul breathing). Point-of-care capillary glucose is 460 mg/dL. Arterial blood gas shows pH 7.18, HCO3⁻ 10 mEq/L, and pCO2 24 mmHg. Serum potassium is 3.1 mEq/L and serum sodium is 134 mEq/L. Urine ketones are strongly positive. What is the most critical initial intervention before starting continuous intravenous regular insulin infusion?

A.Administer intravenous sodium bicarbonate 100 mEq bolus

B.Administer a subcutaneous dose of glargine insulin

C.Infuse 5% dextrose in water at 200 mL/hr

D.Initiate aggressive isotonic saline hydration and intravenous potassium chloride replacement

Explanation: In diabetic ketoacidosis (DKA), administering insulin drives potassium into cells, which can trigger life-threatening hypokalemia and cardiac arrhythmias if baseline potassium is low. Guidelines mandate that when serum potassium is < 3.3 mEq/L, insulin must be withheld while aggressive IV isotonic saline hydration and potassium repletion (20–30 mEq/hr) are initiated until potassium exceeds 3.3 mEq/L.

5A 71-year-old female with a history of ischemic cardiomyopathy presents to the emergency department with acute dyspnea, orthopnea, and bilateral leg swelling. Physical examination reveals jugular venous distention to the angle of the jaw, bilateral pulmonary crackles extending to mid-lung fields, and an S3 gallop. Vital signs: BP 160/95 mmHg, HR 102 bpm, RR 28/min, SpO2 88% on ambient air. Which initial pharmacologic combination provides the most rapid symptomatic and hemodynamic improvement?

A.Intravenous loop diuretic (furosemide) plus intravenous vasodilator (nitroglycerin) and supplemental oxygen

B.Intravenous beta-blocker (metoprolol tartrate) and oral spironolactone

C.Intravenous digoxin and immediate oral verapamil

D.Intravenous normal saline 1000 mL bolus and oral enalapril

Explanation: Acute decompensated heart failure with pulmonary edema and elevated blood pressure ('wet and warm') is treated primarily with IV loop diuretics (furosemide) to reduce fluid overload and IV vasodilators (nitroglycerin) to rapidly reduce cardiac preload and afterload. Supplemental oxygen or non-invasive positive pressure ventilation (CPAP/BiPAP) should be applied to correct hypoxemia.

6A 73-year-old female with a history of hypertension and well-controlled type 2 diabetes presents for an annual checkup. An ECG reveals asymptomatic atrial fibrillation with a ventricular response rate of 82 bpm. Transthoracic echocardiography shows normal left ventricular systolic function (LVEF 58%) and mild left atrial enlargement. She has no history of stroke, TIA, or vascular disease. According to the CHA2DS2-VASc scoring system, what is her stroke risk score and the recommended stroke prevention strategy?

A.Score of 2; oral antiplatelet monotherapy with aspirin 100 mg daily

B.Score of 4; oral anticoagulation with a Direct Oral Anticoagulant (DOAC) or Warfarin

C.Score of 1; no antithrombotic therapy required

D.Score of 5; dual antiplatelet therapy with aspirin and clopidogrel

Explanation: Her CHA2DS2-VASc score is calculated as: Age 65–74 (1 point), Female sex (1 point), Hypertension (1 point), and Diabetes mellitus (1 point) = 4 points. For non-valvular atrial fibrillation with a CHA2DS2-VASc score ≥ 2 in males or ≥ 3 in females, oral anticoagulation (preferably a DOAC such as apixaban, rivaroxaban, or dabigatran) is strongly recommended for stroke prevention. Aspirin or dual antiplatelets are inferior and ineffective for thromboembolism prevention in AF.

7A 44-year-old male is evaluated for persistent hypertension (BP 168/104 mmHg) despite adherent triple therapy with amlodipine 10 mg, valsartan 160 mg, and hydrochlorothiazide 25 mg daily. Routine labs reveal serum potassium of 3.1 mEq/L (normal: 3.5–5.0 mEq/L) and serum sodium of 144 mEq/L. Which screening laboratory test is most appropriate to confirm or exclude primary hyperaldosteronism as the underlying secondary cause?

A.24-hour urinary free cortisol excretion

B.24-hour urinary metanephrines and normetanephrines

C.Plasma Aldosterone Concentration to Plasma Renin Activity (or concentration) ratio (ARR)

D.Renal artery duplex ultrasound

Explanation: Primary hyperaldosteronism (Conn's syndrome or bilateral adrenal hyperplasia) is the most common endocrine cause of secondary and resistant hypertension. The recommended initial screening test is the morning plasma aldosterone-to-renin ratio (ARR). An elevated ratio (typically ARR > 20–30 with aldosterone > 15 ng/dL) warrants confirmatory suppression testing.

8A 66-year-old male with a 40 pack-year smoking history and severe baseline COPD presents with increased dyspnea, increased sputum volume, and new yellowish-green purulent sputum over the past 48 hours (Anthonisen Type 1 exacerbation). Pulse oximetry is 90% on room air. In addition to inhaled short-acting bronchodilators (salbutamol plus ipratropium) and controlled oxygen, what is the guideline-directed standard medical therapy for this exacerbation?

A.Inhaled corticosteroids alone without systemic steroids or antibiotics

B.Intravenous aminophylline infusion for 7 days

C.Oral broad-spectrum fluoroquinolone for 21 days without corticosteroids

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

Explanation: According to GOLD and Argentine respiratory consensus guidelines, an acute COPD exacerbation presenting with all three Cardinal symptoms (worsening dyspnea, increased sputum volume, and increased sputum purulence) benefits from antimicrobial therapy (typically 5–7 days with amoxicillin-clavulanate, azithromycin, or doxycycline) and a short course of systemic corticosteroids (prednisone 40 mg daily for 5 days) to accelerate recovery and reduce relapse.

9A 32-year-old woman taking oral contraceptive pills presents with sudden-onset sharp right-sided pleuritic chest pain, dyspnea, and tachycardia (HR 110 bpm). Blood pressure is 120/75 mmHg and RR is 22/min. Physical examination of the lower extremities shows no asymmetry or edema. Her simplified Wells score for pulmonary embolism is 3 (moderate/intermediate risk). What is the most appropriate next diagnostic step?

A.High-sensitivity D-dimer assay

B.Immediate unfractionated heparin bolus without further diagnostic testing

C.Chest radiography alone to rule out pulmonary embolism

D.Transthoracic echocardiogram alone to rule out acute pulmonary embolism

Explanation: In hemodynamically stable patients with low or intermediate clinical probability for pulmonary embolism (PE) by Wells or Geneva criteria, the recommended next step is a high-sensitivity D-dimer test. A normal D-dimer safely rules out PE without the need for radiation and contrast. If positive, computed tomography pulmonary angiography (CTPA) is indicated.

10A 64-year-old male is brought to the hospital 75 minutes after the sudden onset of right-sided hemiplegia and expressive aphasia. Non-contrast brain CT reveals no acute intracranial hemorrhage or early hypodense infarction. His blood pressure is 165/95 mmHg, blood glucose is 138 mg/dL, platelet count is 220,000/mm³, and INR is 1.0. He has no history of head trauma, recent surgery, or gastrointestinal bleeding. What is the most appropriate immediate intervention?

A.Oral administration of aspirin 325 mg and clopidogrel 300 mg

B.Intravenous recombinant tissue plasminogen activator (rtPA / alteplase) at 0.9 mg/kg

C.Lower the systolic blood pressure acutely to < 120 mmHg using intravenous nitroprusside

D.Immediate intravenous therapeutic unfractionated heparin infusion

Explanation: Intravenous thrombolysis with rtPA (alteplase 0.9 mg/kg, maximum 90 mg) is the proven first-line therapy for acute ischemic stroke when initiated within 4.5 hours of symptom onset in eligible patients after intracranial hemorrhage has been ruled out by non-contrast CT. His blood pressure is < 185/110 mmHg and he has no contraindications.

About the Residencias Mendoza — Medicina (Primer Nivel) Exam

The Concurso de Residencias en Salud de la Provincia de Mendoza (Primer Nivel — Medicina) is the official provincial competitive examination administered annually by the Ministerio de Salud y Deportes de Mendoza for entry into postgraduate medical residency programs across public and affiliated private hospitals throughout Mendoza, Argentina.
