Q1 Question 1 of 100
Q1. A 34-year-old woman presents with progressive muscle weakness, ptosis, and fatigue that worsens
with repetitive activity. Electromyography reveals a decremental response to repetitive nerve stimulation.
This clinical presentation is most consistent with a pathophysiologic defect involving which of the following
mechanisms?
A. Defective presynaptic acetylcholine synthesis and packaging
B. Demyelination of peripheral motor nerve fibers
C. Presynaptic voltage-gated calcium channel dysfunction
D. Antibody-mediated destruction of postsynaptic acetylcholine receptors
Correct Answer: D
Rationale:
The patient's presentation with ptosis, muscle weakness worsening with use, and decremental EMG response is
classic for myasthenia gravis, caused by autoantibodies against postsynaptic acetylcholine receptors at the
neuromuscular junction. Presynaptic calcium channel dysfunction describes Lambert-Eaton syndrome, which typically
presents with proximal weakness that improves with repetition, not worsens.
Q2 Question 2 of 100
Q2. A 6-month-old infant is evaluated for failure to thrive, hepatosplenomegaly, and progressive
neurologic deterioration. Enzyme analysis reveals deficient glucocerebrosidase activity. Accumulation of
which of the following substrates is responsible for this patient's symptoms?
A. Sphingomyelin in reticuloendothelial cells
B. Glucosylceramide in macrophage lysosomes
C. Ganglioside GM2 in neuronal lysosomes
D. Heparan sulfate in connective tissue fibroblasts
Correct Answer: B
Rationale:
Deficient glucocerebrosidase leads to Gaucher disease, characterized by accumulation of glucosylceramide
(glucocerebroside) within macrophage lysosomes. Sphingomyelin accumulation occurs in Niemann-Pick disease,
ganglioside GM2 accumulation in Tay-Sachs disease, and heparan sulfate accumulation in mucopolysaccharidoses
such as Hurler syndrome.

,Q3 Question 3 of 100
Q3. A 42-year-old man with a long-standing history of gastroesophageal reflux disease undergoes upper
endoscopy, which reveals salmon-colored mucosa in the distal esophagus extending 3 cm above the
gastroesophageal junction. Biopsy confirms intestinal metaplasia. This patient is at greatest risk for
developing which of the following malignancies?
A. Squamous cell carcinoma of the esophagus
B. Adenocarcinoma of the esophagus
C. Gastric lymphoma
D. Gastrointestinal stromal tumor
Correct Answer: B
Rationale:
The findings describe Barrett esophagus, a complication of chronic GERD in which normal squamous epithelium is
replaced by intestinal metaplasia. Barrett esophagus is the major risk factor for esophageal adenocarcinoma.
Squamous cell carcinoma is associated with alcohol, smoking, and achalasia, not Barrett metaplasia.
Q4 Question 4 of 100
Q4. A 28-year-old woman of Ashkenazi Jewish descent presents with vague abdominal discomfort and is
found to have a large pelvic mass. Pathologic examination of the excised mass reveals a tumor with
sheets of uniform cells with cleared cytoplasm and central nuclei, previously termed a 'skyline' pattern.
Cytogenetic analysis is most likely to reveal a translocation involving which chromosomes?
A. t(9;22)
B. t(8;14)
C. t(12;15)
D. t(11;22)
Correct Answer: D
Rationale:
The description is consistent with Ewing sarcoma or a related primitive neuroectodermal tumor (PNET), which
characteristically harbors a t(11;22)(q24;q12) translocation producing the EWS-FLI1 fusion gene. The t(9;22) is the
Philadelphia chromosome seen in CML, t(8;14) is associated with Burkitt lymphoma, and t(12;15) is seen in
congenital fibrosarcoma.

, Q5 Question 5 of 100
Q5. A 55-year-old man with a 30-pack-year smoking history presents with a persistent cough and weight
loss. Chest imaging reveals a 4 cm central lung mass. Biopsy shows sheets of small, round blue cells with
scant cytoplasm, finely granular chromatin, and absent nucleoli. Immunohistochemistry is positive for
chromogranin and synaptophysin. Which molecular abnormality is most characteristic of this tumor type?
A. KRAS mutation
B. EGFR mutation
C. Amplification of MYC family genes
D. ALK rearrangement
Correct Answer: C
Rationale:
The biopsy findings describe small cell lung carcinoma (SCLC), a neuroendocrine tumor positive for chromogranin
and synaptophysin. SCLC is characteristically associated with amplification of MYC family genes (MYC, MYCL,
MYCN). KRAS and EGFR mutations are more typical of adenocarcinoma, and ALK rearrangements are found in a
subset of non-small cell lung cancers.
Q6 Question 6 of 100
Q6. A 3-year-old boy is evaluated for recurrent bacterial sinopulmonary infections and chronic diarrhea.
Laboratory studies reveal very low IgG, IgA, and IgM levels, with absent B cells on flow cytometry. Genetic
testing reveals a mutation in the BTK gene. This condition is inherited in which of the following patterns?
A. Autosomal recessive
B. Autosomal dominant
C. X-linked recessive
D. Mitochondrial inheritance
Correct Answer: C
Rationale:
The patient has X-linked agammaglobulinemia (Bruton disease), caused by mutations in the BTK gene located on the
X chromosome. This results in absent mature B cells and severely depressed immunoglobulin levels. It is inherited in
an X-linked recessive pattern, affecting males almost exclusively. Autosomal recessive forms of agammaglobulinemia
exist but involve different genes.
