Introduction
This comprehensive assessment is designed to rigorously evaluate your readiness for the COMSAE Phase 3
examination. It focuses on the integration of foundational medical knowledge with advanced clinical reasoning,
professionalism, and systems-based practice. The exam utilizes a multiple-choice and scenario-based structure to
simulate real-world clinical decision-making, emphasizing the safe and effective application of medical knowledge
in patient care. This test bank is intended to serve as a definitive tool for self-assessment, highlighting key areas for
review and reinforcing the critical thinking skills required for success in the clinical setting.
SECTION ONE: QUESTIONS 1-100
,1. A 72-year-old male with a history of hypertension and type 2 diabetes presents with a three-day history of
progressive dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. On examination, he has jugular venous
distension, bilateral crackles up to the mid-lung fields, and 2+ pitting edema in his lower extremities. His
blood pressure is 165/95 mmHg and heart rate is 102 bpm. An ECG reveals left ventricular hypertrophy.
Which of the following is the most appropriate initial pharmacologic intervention to reduce both preload
and afterload in this patient?
A. Intravenous furosemide
B. Sublingual nitroglycerin
C. Oral lisinopril
D. Intravenous sodium nitroprusside
🟢 D. Intravenous sodium nitroprusside
🔴 RATIONALE: This patient is presenting with acute decompensated heart failure with evidence of fluid
overload and hypertension. Sodium nitroprusside is a potent balanced vasodilator that reduces both preload
and afterload, making it the ideal agent for acute management in a hypertensive patient with pulmonary
edema. While furosemide reduces preload and nitroglycerin primarily reduces preload, they do not address
afterload reduction. Lisinopril is an oral agent with a slower onset, unsuitable for the acute setting.
2. A 55-year-old woman presents with a two-week history of progressive weakness in her proximal upper
and lower extremities. She reports difficulty rising from a chair and brushing her hair. She also notes a rash
on her face and hands. Physical exam reveals symmetric, proximal muscle weakness and a heliotrope rash on
her eyelids. Laboratory studies show elevated creatine kinase and aldolase levels. Which of the following is
the most likely diagnosis?
,A. Polymyalgia rheumatica
B. Dermatomyositis
C. Systemic lupus erythematosus
D. Inclusion body myositis
🟢 B. Dermatomyositis
🔴 RATIONALE: The classic presentation of proximal muscle weakness, heliotrope rash (periorbital purplish
discoloration), and Gottron's papules (not mentioned but often present on hands) is highly characteristic of
dermatomyositis. Polymyalgia rheumatica presents with muscle aches and stiffness, not weakness and a rash.
SLE can present with a malar rash, not heliotrope, and muscle weakness is less prominent. Inclusion body
myositis typically affects distal muscles, is more common in older men, and is less responsive to treatment.
3. A 45-year-old male with a history of chronic alcoholism presents to the emergency department with
severe, tearing chest pain that radiates to his back. His blood pressure is 180/110 mmHg in the right arm and
160/90 mmHg in the left arm. On examination, he has a diastolic murmur. Which of the following is the most
appropriate initial imaging study to confirm the suspected diagnosis?
A. Chest X-ray
B. Transthoracic echocardiogram (TTE)
C. Transesophageal echocardiogram (TEE)
D. Computed tomography (CT) angiography of the chest
🟢 C. Transesophageal echocardiogram (TEE)
🔴 RATIONALE: The classic presentation of aortic dissection includes severe, tearing chest pain radiating to the
back with a pulse or blood pressure differential. While CT angiography is the gold standard for diagnosis, TEE is
, the most appropriate initial imaging study in the emergency setting as it can be performed rapidly at the
bedside without contrast, especially in a hemodynamically unstable patient. A chest X-ray may show a widened
mediastinum but is not diagnostic. TTE is less sensitive for visualizing the descending aorta.
4. A 28-year-old woman at 32 weeks gestation presents with a headache, blurred vision, and right upper
quadrant pain. Her blood pressure is 160/105 mmHg and she has 3+ proteinuria on a urine dipstick. Which of
the following is the most definitive treatment for this patient's condition?
A. Intravenous magnesium sulfate
B. Oral labetalol
C. Delivery of the fetus
D. Dexamethasone administration
🟢 C. Delivery of the fetus
🔴 RATIONALE: This patient is presenting with preeclampsia with severe features, including severe
hypertension, headache, visual changes, and epigastric pain, which may indicate HELLP syndrome. The only
definitive treatment for preeclampsia is delivery of the fetus and placenta. Magnesium sulfate is administered to
prevent seizures (eclampsia) but is not curative. Antihypertensives like labetalol manage blood pressure but do
not address the underlying pathology. Dexamethasone is used to accelerate fetal lung maturity in preterm
labor.
5. A 6-year-old boy is brought to the clinic with a rash and joint pain. He had a sore throat three weeks ago.
On examination, he has erythematous, warm, and tender joints in his knees and ankles. A new murmur is
auscultated. Which of the following laboratory findings would be most consistent with the suspected
diagnosis?
