Sample CMG Medicina General Practice Questions

Try these sample questions to review concepts for the CMG Medicina General exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A 52-year-old male with a newly confirmed diagnosis of primary arterial hypertension (blood pressure 146/92 mmHg) and no history of diabetes, chronic kidney disease, or cardiovascular events begins lifestyle modifications. According to current international hypertension guidelines (ACC/AHA, ESC/ESH), which drug class is a recommended first-line option if drug therapy is started?

A.Angiotensin-converting enzyme inhibitor (ACE inhibitor) or thiazide diuretic

B.Non-dihydropyridine calcium channel blocker (e.g., diltiazem or verapamil)

C.Centrally acting alpha-2 adrenergic agonist (e.g., clonidine or methyldopa)

D.Direct peripheral arteriolar vasodilator (e.g., hydralazine or minoxidil)

Explanation: NOM-030-SSA2-2009 leaves drug selection to the national pharmacological treatment guidance; in international guidelines (ACC/AHA, ESC/ESH), first-line drug classes for essential hypertension without compelling comorbidities are ACE inhibitors, ARBs, thiazide or thiazide-like diuretics, and dihydropyridine calcium channel blockers. ACE inhibitors and thiazides have demonstrated robust reduction in cardiovascular morbidity and mortality.

2A 48-year-old female presents for a routine check-up. She is asymptomatic. Her body mass index (BMI) is 31 kg/m². A fasting plasma glucose test reveals 134 mg/dL. A repeat fasting glucose test obtained one week later is 130 mg/dL. In accordance with NOM-015-SSA2-2010, what is the definitive diagnosis and primary initial management step?

A.Impaired fasting glucose; prescribe acarbose and repeat fasting testing in 6 months

B.Type 2 diabetes mellitus; initiate medical nutrition therapy, exercise, and metformin

C.Metabolic syndrome only; recommend lifestyle changes without medical pharmacotherapy

D.Normal glucose tolerance; recommend hypocaloric diet and repeat annual health screening

Explanation: NOM-015-SSA2-2010 defines diabetes mellitus as two fasting plasma glucose readings of 126 mg/dL or greater taken on different days in an asymptomatic patient. Once confirmed, first-line management consists of structured lifestyle intervention (diet and exercise) combined with metformin unless contraindicated.

3A 64-year-old male with long-standing hypertension and a previous anterior myocardial infarction presents with worsening exertional dyspnea (NYHA functional class III) and bilateral ankle edema. Echocardiography demonstrates a left ventricular ejection fraction (LVEF) of 32%. He is currently taking enalapril 10 mg twice daily and furosemide 40 mg daily. Which medication should be added next to reduce mortality, provided his heart rate is 76 bpm and potassium is 4.4 mEq/L?

A.Digoxin 0.25 mg once daily with periodic serum digoxin concentration monitoring

B.Amlodipine 10 mg once daily for peripheral arterial vasodilation and afterload

C.Carvedilol 3.125 mg twice daily titrated gradually toward target guideline doses

D.Isosorbide dinitrate 20 mg orally three times daily with a nitrate-free interval

Explanation: In patients with heart failure with reduced ejection fraction (HFrEF) who are clinically stable on an ACE inhibitor and diuretic, guideline-directed medical therapy requires adding an evidence-based beta-blocker (carvedilol, bisoprolol, or metoprolol succinate) with gradual upward titration to reduce hospitalizations and all-cause mortality.

4A 24-year-old female presents with recurrent episodes of wheezing, nocturnal dry cough, and chest tightness that worsen with cold air exposure. Spirometry demonstrates an FEV1/FVC ratio of 68% that increases by 15% and 240 mL following inhalation of 400 mcg of salbutamol. What is the most appropriate long-term controller therapy according to Mexican and GINA asthma guidelines?

A.Short-acting beta-2 agonist (salbutamol) as needed alone for acute symptom relief

B.Oral systemic corticosteroid maintenance therapy (prednisone 20 mg once daily)

C.Oral methylxanthine (theophylline 200 mg twice daily) as maintenance bronchodilator

D.Low-dose inhaled corticosteroid combined with formoterol as controller and reliever

Explanation: Mexican and international asthma guidelines (GINA) strongly recommend that all adults and adolescents with asthma receive inhaled corticosteroid (ICS) containing controller therapy to reduce the risk of severe exacerbations and asthma-related death. The preferred regimen across tracks is low-dose ICS-formoterol taken as maintenance and reliever or as-needed controller.

5A 68-year-old male with a 40 pack-year smoking history presents with productive morning cough for the past 3 consecutive years and progressive exertional breathlessness. Physical examination reveals distant breath sounds and prolonged expiration. Post-bronchodilator spirometry shows an FEV1/FVC ratio of 0.62 and an FEV1 of 58% of predicted. What is the confirmed diagnosis and GOLD spirometric severity stage?

A.Chronic obstructive pulmonary disease (COPD), GOLD stage 2 (moderate limitation)

B.Asthma-COPD overlap syndrome, GOLD stage 1 (mild persistent airflow limitation)

C.Severe persistent bronchial asthma with fixed obstruction, GOLD stage 3 criteria

D.Idiopathic pulmonary fibrosis with traction bronchiectasis, stage 2 impairment

Explanation: A post-bronchodilator FEV1/FVC < 0.70 confirms persistent airflow limitation diagnostic of COPD. According to GOLD criteria endorsed by Mexican respiratory clinical guidelines, an FEV1 between 50% and 79% of predicted corresponds to GOLD 2 (moderate airflow limitation).

6A 58-year-old previously healthy female presents to the primary care clinic with a 4-day history of productive cough with rust-colored sputum, right pleuritic chest pain, fever of 38.8°C, and chills. Vital signs show respiratory rate 22 breaths/min, blood pressure 125/80 mmHg, pulse 88 bpm. Auscultation reveals inspiratory crackles and bronchial breath sounds at the right lung base. Chest radiograph confirms right lower lobe consolidation. What is the most appropriate empirical outpatient antimicrobial therapy according to the ATS/IDSA community-acquired pneumonia guideline?

A.Oral ciprofloxacin 500 mg twice daily for 10 days for broad gram-negative coverage

B.Oral amoxicillin 1 g three times daily or amoxicillin-clavulanate with a macrolide

C.Oral vancomycin 125 mg four times daily for empirical methicillin-resistant coverage

D.Intramuscular gentamicin 80 mg daily for 7 days with peak and trough monitoring

Explanation: The 2019 ATS/IDSA community-acquired pneumonia guideline recommends high-dose oral amoxicillin (1 g every 8 hours) for healthy adult outpatients without comorbidities. Doxycycline, or a macrolide where pneumococcal macrolide resistance is below 25%, are alternatives. Patients with comorbidities receive amoxicillin/clavulanate (or a cephalosporin) combined with a macrolide or doxycycline, or a respiratory fluoroquinolone. This covers Streptococcus pneumoniae and atypical pathogens.

7A 44-year-old male presents with burning retrosternal pain radiating upward that occurs 45 minutes after eating spicy meals and upon lying supine. He has had symptoms twice weekly for 6 months. He reports no dysphagia, odynophagia, involuntary weight loss, gastrointestinal bleeding, or anemia. Which initial therapeutic strategy is recommended by the American College of Gastroenterology (ACG) guideline for this patient with uncomplicated gastroesophageal reflux disease (GERD)?

A.Immediate urgent referral for upper endoscopy, esophageal manometry, and pH monitoring

B.Continuous daily oral sucralfate suspension 1 g four times daily for 12 straight months

C.An 8-week empirical trial of a standard-dose oral proton pump inhibitor before breakfast

D.Immediate laparoscopic Nissen fundoplication with posterior crural repair without drugs

Explanation: In patients with typical symptoms of GERD (pyrosis and regurgitation) without alarm features (weight loss, dysphagia, hematemesis, anemia, or new onset at an older age), the ACG 2022 guideline recommends an empirical trial of a proton pump inhibitor (such as omeprazole 20 mg or pantoprazole 40 mg daily before breakfast) for 4 to 8 weeks as both diagnostic confirmation and primary therapy.

8A 56-year-old male with a history of alcohol use disorder presents with abdominal distension and jaundice. Examination reveals scleral icterus, palmar erythema, shifting dullness with a fluid wave, and mild lower extremity edema. Diagnostic paracentesis yields clear yellow fluid with a serum-ascites albumin gradient (SAAG) of 1.4 g/dL and total protein of 1.2 g/dL. What does this SAAG indicate?

A.Peritoneal carcinomatosis with exudative ascites and malignant peritoneal seeding

B.Peritoneal tuberculosis with lymphatic obstruction and elevated adenosine deaminase

C.Nephrotic syndrome with severe hypoalbuminemia and impaired oncotic vascular pressure

D.Portal hypertension related to cirrhosis or sinusoidal architectural distortion

Explanation: A serum-ascites albumin gradient (SAAG) of 1.1 g/dL or greater indicates the presence of portal hypertension with high diagnostic accuracy (>=97%), most commonly due to cirrhosis, alcoholic hepatitis, or congestive heart failure. A SAAG < 1.1 g/dL points to non-portal causes such as peritoneal carcinomatosis or peritoneal tuberculosis.

9A 36-year-old female presents with heat intolerance, palpitations, involuntary weight loss of 5 kg over two months, and irritability. Physical examination reveals resting sinus tachycardia at 108 bpm, fine hand tremor, and a diffusely enlarged, non-tender thyroid gland with an audible bruit. Serum TSH is <0.01 microIU/mL and free T4 is 3.8 ng/dL (reference: 0.8–1.8 ng/dL). What is the most likely diagnosis?

A.Graves' disease (toxic diffuse goiter with thyroid-stimulating immunoglobulins)

B.Subacute granulomatous thyroiditis (de Quervain) with capsular tenderness and fever

C.Hashimoto's autoimmune thyroiditis in hypothyroid phase with myxedema and fatigue

D.Toxic multinodular goiter (Plummer disease) with autonomous hyperfunctioning adenomas

Explanation: Primary hyperthyroidism characterized by suppressed TSH, elevated free T4, diffuse non-tender goiter with an audible vascular bruit, and signs of thyrotoxicosis in a young female is typical of Graves' disease, mediated by autoantibodies against the TSH receptor (TRAb).

10A 62-year-old female with primary hypothyroidism on levothyroxine 75 mcg daily attends a routine follow-up. She feels well and has no fatigue or cold intolerance. Her serum TSH is 0.15 microIU/mL (reference: 0.4–4.5 microIU/mL) and free T4 is at the upper limit of normal. What is the most appropriate management according to clinical endocrinology guidelines?

A.Discontinue levothyroxine immediately and re-evaluate the full thyroid panel in 4 weeks

B.Decrease levothyroxine dosage slightly (e.g., to 62.5 mcg daily) and recheck TSH in 6-8 weeks

C.Increase levothyroxine dosage to 100 mcg daily to suppress pituitary secretion completely

D.Maintain the current levothyroxine dose unchanged because the patient feels clinically well

Explanation: A suppressed TSH (<0.4 microIU/mL) indicates iatrogenic exogenous subclinical hyperthyroidism. In postmenopausal women, prolonged TSH suppression accelerates bone mineral density loss (osteoporosis) and increases the risk of atrial fibrillation. A modest dosage decrease (12.5–25 mcg) with retesting of TSH in 6–8 weeks is indicated.

Frequently Asked Questions

What is the CMG Certificación en Medicina General?

The Certificación en Medicina General is a voluntary professional certification administered by the Consejo Nacional de Certificación en Medicina General A.C. (CMG) and normed by CONAMEGE. It validates the clinical competence, medical knowledge, and professional practice standards of licensed general practitioners (médicos cirujanos) across Mexico.

How does the CMG certification differ from the EGEL Plus Medicina?

The EGEL Plus Medicina is an academic graduation and exit assessment administered by Ceneval to university graduates completing their medical degree. In contrast, the CMG certification is a voluntary professional board certification for practicing general physicians who already hold their degree (título) and professional license (cédula profesional).

When are the examination sittings held in 2026?

According to the CMG Convocatoria Nacional 2026, sittings are scheduled for 28 February 2026 (application deadline 31 January), 27 June 2026 (application deadline 30 May), and 31 October 2026 (application deadline 30 September). Examinations are administered digitally at authorized testing venues managed by each state council.

What are the eligibility requirements and registration fees?

Candidates must possess a título and cédula profesional in general medicine (médico cirujano), an official photo ID, CURP, and documented proof of current clinical practice in general medicine. The registration fee is MXN 4,500, payable directly to the corresponding state council (Consejo Estatal).

How is the CMG certification maintained and renewed?

Certification is valid for 5 years. Physicians renew it through curricular evaluation with a minimum of 300 points (150 from continuing medical education and 150 from clinical activity); applicants who do not reach the minimum are called to sit the national certification examination instead.

Why does this practice bank present questions in English?

The official CMG examination and its preparation materials are in Spanish. This OpenExamPrep bank is an independent English-language MCQ study adaptation, not an official translation or exam simulation, developed to reinforce clinical concepts, current clinical guidelines, and Official Mexican Standards (NOM) while preserving authentic Spanish regulatory terminology.
