Introduction
This comprehensive assessment is designed to evaluate the clinical knowledge, diagnostic reasoning, and patient
management skills essential for success on COMSAE Phase 3. The examination consists of 100 multiple-choice
questions that integrate foundational medical sciences with applied clinical practice across all major specialty
,areas. Each question presents realistic clinical scenarios requiring the examinee to demonstrate critical thinking,
evidence-based decision-making, and appropriate application of medical knowledge in complex healthcare
situations. The assessment emphasizes the ability to synthesize information, prioritize interventions, and navigate
ethical and legal considerations in patient care. Questions are structured to mirror the format and rigor of the
actual COMSAE examination, providing a reliable measure of readiness for clinical practice.
SECTION ONE: QUESTIONS 1-100
Question 1
A 72-year-old male with a history of hypertension and type 2 diabetes presents with acute onset of severe right
lower quadrant abdominal pain, nausea, and fever. Physical examination reveals localized tenderness and
guarding in the right lower quadrant. Laboratory studies show leukocytosis with a left shift. CT scan of the
abdomen reveals an inflamed appendix with a 4 cm abscess. Which of the following is the most appropriate
initial management step?
A. Emergent laparoscopic appendectomy
B. Broad-spectrum antibiotics and observation
C. Percutaneous drainage of the abscess followed by interval appendectomy
D. Open appendectomy with abdominal washout
🟢 C. Percutaneous drainage of the abscess followed by interval appendectomy
,🔴 RATIONALE: In the presence of a periappendiceal abscess, the standard of care involves percutaneous
drainage of the abscess and antibiotic therapy, followed by interval appendectomy after 6-8 weeks once
inflammation has resolved. This approach reduces the risk of complications and allows for a safer surgical
procedure.
Question 2
A 45-year-old woman presents with a 3-month history of progressive fatigue, weight loss, and night sweats.
Physical examination reveals cervical lymphadenopathy. A lymph node biopsy shows Reed-Sternberg cells on
microscopic examination. Which of the following is the most important prognostic factor in this patient's
condition?
A. Age at diagnosis
B. Number of involved lymph node regions
C. Presence or absence of B symptoms
D. Erythrocyte sedimentation rate
🟢 B. Number of involved lymph node regions
🔴 RATIONALE: The Ann Arbor staging system, which incorporates the number of involved lymph node regions,
is the most important prognostic factor in Hodgkin lymphoma. Stage at presentation directly correlates with
survival outcomes and guides treatment decisions. The presence of B symptoms, age, and ESR are also
prognostic but secondary to staging.
, Question 3
A 28-year-old primigravida at 39 weeks gestation presents to the labor and delivery unit with regular uterine
contractions occurring every 3-4 minutes. Cervical examination reveals 4 cm dilation and 80% effacement. Fetal
heart rate tracing shows accelerations and moderate variability. Which of the following is the most appropriate
next step in management?
A. Administer oxytocin for augmentation
B. Perform artificial rupture of membranes
C. Continue supportive care and allow labor to progress
D. Prepare for immediate cesarean delivery
🟢 C. Continue supportive care and allow labor to progress
🔴 RATIONALE: This patient is in active labor with reassuring fetal heart rate tracing. No interventions are
indicated at this time. Spontaneous labor progression with supportive care is appropriate. Interventions such as
oxytocin or amniotomy should be reserved for cases of abnormal labor progression or other indications.
Question 4
A 65-year-old male with chronic obstructive pulmonary disease presents with acute worsening of dyspnea,
increased sputum production with purulent appearance, and fever. Arterial blood gas shows pH 7.30, PaCO2 65
mmHg, PaO2 55 mmHg, and HCO3 28 mEq/L. Which of the following is the most appropriate initial
management?
