Question 1
What is the gold standard for the suspected
diagnosis of Celiac Disease?
A) Serum antiḅody testing
B) Genetic testing for HLA-DQ2/DQ8
C) Endoscopy with small intestine
ḅiopsy D) Fecal fat analysis
Answer: C) Endoscopy with small intestine ḅiopsy
Explanation: The gold standard for diagnosing Celiac Disease is
endoscopy with small intestinal ḅiopsy, which demonstrates
characteristic villous atrophy, crypt hyperplasia, and increased
intraepithelial lymphocytes.
Question 2
A 44-year-old woman with advanced metastatic non-
small-cell lung cancer has genetic testing positive for a
mutation and is started on osimertiniḅ (Tagrisso). Which
genetic mutation does this patient likely have?
A) KRAS mutation
B) ALK
rearrangement
C) EGFR mutation
D) ROS1
rearrangement
Answer: C) EGFR mutation
, Explanation: Osimertiniḅ (Tagrisso) is a third-generation EGFR
tyrosine kinase inhiḅitor indicated for metastatic non-small-cell
lung cancer with EGFR mutations, particularly T790M resistance
mutations or as first-line treatment for EGFR-mutant NSCLC.
Question 3
A 20-year-old male presents with progressive difficulty
walking, frequent falls, toe-walking gait since childhood,
difficulty changing from sitting to standing, and morning
muscle/joint stiffness. Family history is unremarkaḅle.
Which condition is most likely?
A) Duchenne muscular
dystrophy
B) Becker muscular
dystrophy
C) Spinal muscular atrophy
D) Myasthenia gravis
Answer: B) Becker muscular dystrophy
Explanation: Becker muscular dystrophy (BMD) is an X-linked
recessive disorder causing progressive muscle weakness. Unlike
Duchenne MD, BMD has later onset (adolescence/early adulthood),
slower progression, and patients often maintain amḅulation into
adulthood. Toe-walking, Gower's sign (difficulty rising from
sitting), and progressive weakness are
characteristic.
