Introduction
This comprehensive self-assessment examination is designed to rigorously evaluate your readiness for the COMSAE
Phase 3. It assesses your ability to synthesize foundational medical knowledge with applied clinical skills, focusing
on real-world patient management and critical decision-making. The exam is structured as a series of multiple-
choice and scenario-based questions that challenge your understanding of regulatory standards, ethical
obligations, and effective communication. Success requires not only recalling facts but also applying principles of
patient safety, systems-based practice, and evidence-based medicine in complex, ambulatory, and hospital-based
settings. This assessment serves as a vital tool to identify strengths and areas for focused study.
,SECTION ONE: QUESTIONS 1–100
1. A 72-year-old male with a history of hypertension and type 2 diabetes presents with a two-day history of
severe, tearing chest pain that radiates to his back. His blood pressure is 110/70 mmHg in the right arm and
100/60 mmHg in the left arm. Which of the following is the most appropriate initial imaging study to
confirm the suspected diagnosis?
A. Chest X-ray
B. CT angiography of the chest
C. Transthoracic echocardiogram
D. Transesophageal echocardiogram
🟢B
🔴 RATIONALE: CT angiography of the chest is the gold standard for the rapid diagnosis of an aortic dissection,
which is suspected given the history of acute, tearing chest pain radiating to the back with a pulse deficit. It is
widely available, sensitive, and specific. Transesophageal echocardiogram is also accurate but is more invasive
and operator-dependent. Chest X-ray may show a widened mediastinum but is not definitive.
2. A 28-year-old woman presents to the clinic with a chief complaint of fatigue, weight gain, cold
intolerance, and constipation for the past three months. Her TSH is 12.5 mIU/L (normal: 0.4-4.0). What is the
most appropriate next step in management?
A. Initiate levothyroxine 25 mcg daily
B. Initiate levothyroxine 100 mcg daily
C. Measure free T4
D. Order a thyroid ultrasound
,🟢C
🔴 RATIONALE: A low TSH and elevated TSH indicates primary hypothyroidism. The most appropriate next step
is to measure free T4 to confirm the diagnosis and assess the severity of the disease before initiating treatment.
Starting empiric levothyroxine without free T4 is not ideal. A thyroid ultrasound is not indicated for routine
hypothyroidism.
3. A 60-year-old patient with a history of chronic obstructive pulmonary disease (COPD) is being discharged
from the hospital after an exacerbation. He is prescribed a long-acting beta-agonist (LABA) and a long-
acting muscarinic antagonist (LAMA). He asks you if there is a simpler regimen. Which of the following best
describes the rationale for using this combination therapy?
A. It reduces the risk of systemic corticosteroid use.
B. It is indicated for all patients with COPD regardless of severity.
C. It has a synergistic effect, improving lung function and reducing exacerbations.
D. It is solely for symptom management during exacerbations.
🟢C
🔴 RATIONALE: The combination of a LABA and LAMA provides synergistic bronchodilation and has been
shown to improve lung function and reduce the risk of exacerbations in patients with COPD, particularly those
with more advanced disease. It is not indicated for all patients, nor is it used only for acute exacerbations.
4. A patient with a history of major depressive disorder (MDD) and anxiety is started on an SSRI. He returns
to the clinic after two weeks and complains of an inability to achieve orgasm and decreased libido. What is
the most appropriate initial management strategy?
A. Discontinue the SSRI immediately.
B. Add bupropion to the regimen.
, C. Reassure him that these symptoms will resolve spontaneously in a few weeks.
D. Switch to a different SSRI.
🟢B
🔴 RATIONALE: Sexual dysfunction is a common side effect of SSRIs. The most appropriate initial strategy is to
add bupropion, which has been shown to improve sexual side effects. Switching to another SSRI may be
considered but is not the first step. Symptoms are not likely to resolve spontaneously in a few weeks. Abrupt
discontinuation is dangerous.
5. A 45-year-old male is admitted for acute pancreatitis. He has a history of alcohol use disorder. He is
experiencing severe epigastric pain, nausea, and vomiting. His lipase is 550 U/L. Which of the following is the
most important initial step in managing his pain?
A. Administering oral opioids
B. Administering IV morphine
C. Administering IV fluids
D. Placing a nasogastric tube for decompression
🟢B
🔴 RATIONALE: Pain control is a critical component of managing acute pancreatitis. IV morphine is effective for
severe pain and is often preferred. Oral opioids are not appropriate due to vomiting. Aggressive IV fluid
resuscitation is also critical, but analgesia is the immediate priority for severe pain. A nasogastric tube is not
routine for mild to moderate disease.
6. A 35-year-old woman presents to the emergency department with severe, unilateral headache and
photophobia. Her vital signs are normal. She has a history of migraines. Which of the following is a
contraindication to prescribing sumatriptan?
