Introduction
This comprehensive examination is designed to assess the clinical knowledge and decision-making skills essential
for success in the COMSAE Phase 3. It evaluates the application of foundational medical sciences in the context of
patient management, disease prevention, and health promotion across diverse clinical settings. The exam features
multiple-choice questions that emphasize real-world clinical scenarios, requiring the examinee to integrate
diagnostic, therapeutic, and ethical principles. A strong focus is placed on critical thinking, patient safety, and the
effective utilization of healthcare resources, mirroring the complexities of independent practice.
SECTION ONE: QUESTIONS 1-100
,1. A 67-year-old male with a history of hypertension and type 2 diabetes presents with acute onset of severe,
tearing chest pain that radiates to his back. His blood pressure is 180/110 mmHg in the right arm and 130/80
mmHg in the left arm. What is the most appropriate next step in management?
A. Administer sublingual nitroglycerin
B. Obtain a stat CT angiography of the chest
C. Administer a loading dose of clopidogrel
D. Perform a bedside transthoracic echocardiogram
🟢 B. Obtain a stat CT angiography of the chest
🔴 RATIONALE: The patient's presentation of severe, tearing chest pain with a pulse deficit and blood pressure
differential is classic for an acute aortic dissection. While a stat bedside transthoracic echocardiogram (TTE) can
be useful, CT angiography is the gold standard for confirming the diagnosis and assessing the extent of the
dissection with high sensitivity and specificity. Nitroglycerin and clopidogrel are contraindicated or
inappropriate in this setting as they could worsen the condition or cause bleeding.
2. A 42-year-old female presents with a 6-month history of fatigue, arthralgias, and a malar rash. Laboratory
tests reveal ANA positive at 1:640 (speckled pattern), anti-Smith antibody positive, and anti-dsDNA antibody
positive. Which of the following is the most appropriate initial pharmacologic therapy for her active, non-
renal systemic lupus erythematosus?
A. Prednisone 60 mg daily
B. Hydroxychloroquine
C. Methotrexate
D. Mycophenolate mofetil
,🟢 B. Hydroxychloroquine
🔴 RATIONALE: Hydroxychloroquine is the cornerstone of therapy for all patients with SLE to control disease
activity, reduce flares, and improve long-term prognosis. While corticosteroids can be used for acute flares, they
are not the first-line initial therapy for non-renal disease. Methotrexate and mycophenolate are used for more
severe or refractory disease.
3. A 60-year-old male with a 30-pack-year smoking history presents with a 3-month history of progressive
dyspnea on exertion and a dry cough. On auscultation, you hear fine, late inspiratory crackles at the lung
bases. Chest X-ray shows bilateral reticular opacities. Which of the following is the most likely diagnosis?
A. Chronic obstructive pulmonary disease
B. Idiopathic pulmonary fibrosis
C. Bronchiectasis
D. Congestive heart failure
🟢 B. Idiopathic pulmonary fibrosis
🔴 RATIONALE: The combination of progressive dyspnea, dry cough, fine late inspiratory crackles ("Velcro"
crackles), and a reticular pattern on chest X-ray in a patient with a history of smoking is highly suggestive of
Idiopathic Pulmonary Fibrosis (IPF). COPD typically presents with wheezing and a more productive cough.
Bronchiectasis is characterized by chronic sputum production and coarse crackles. CHF would have other signs
like edema and jugular venous distension.
4. A 28-year-old female G1P0 at 32 weeks gestation presents with a 2-day history of a severe, unilateral
headache and visual disturbances. Her blood pressure is 155/100 mmHg, and her urine dipstick shows 3+
protein. Which of the following is the most appropriate next step in management?
, A. Administer oral labetalol
B. Administer magnesium sulfate intravenously
C. Administer hydralazine intravenously
D. Schedule an induction of labor for the next day
🟢 B. Administer magnesium sulfate intravenously
🔴 RATIONALE: This patient is exhibiting signs of preeclampsia with severe features (severe headache, visual
changes, and severe hypertension with proteinuria). The most appropriate initial step is to administer
intravenous magnesium sulfate for seizure prophylaxis to prevent eclampsia. While antihypertensives like
labetalol or hydralazine should also be used to lower blood pressure, the immediate priority is to reduce the risk
of seizures. Delivery is indicated but not the very first immediate step.
5. A 5-year-old male is brought to the emergency department with a 2-day history of fever, cough, and
difficulty breathing. He has a history of wheezing with respiratory infections. On examination, he is in
respiratory distress with subcostal retractions and a respiratory rate of 40/min. On auscultation, there is
diffuse expiratory wheezing. Which of the following is the most appropriate initial therapy?
A. Oral prednisolone
B. Inhaled albuterol via nebulizer
C. Chest physiotherapy and postural drainage
D. Intravenous antibiotics
🟢 B. Inhaled albuterol via nebulizer
🔴 RATIONALE: The patient's presentation of respiratory distress with diffuse wheezing in a child with a history
of wheezing suggests an acute asthma exacerbation. The first-line therapy for acute bronchospasm is a rapid-
acting bronchodilator like inhaled albuterol. Oral prednisolone is the next step for moderate to severe
