RATED A+
A 26-year-old female presents with fatigue, muscle aches, bloating, numbness,
tingling, and constipation following diarrhea and anti-diarrheal use. Celiac
disease is suspected after antibody testing.
Which follow-up test is considered the gold standard for confirming the
diagnosis?
✔✔ Endoscopy with small intestine biopsy
📝 Explanation: This procedure allows direct visualization and biopsy of the small
intestine to detect villous atrophy, confirming Celiac disease.
A 44-year-old woman with advanced non-small-cell lung cancer (NSCLC)
tests positive for a genetic mutation. She is started on osimertinib (Tagrisso).
Which two mutations are commonly associated with this treatment?
✔✔ EGFR mutation
✔✔ ALK mutation
📝 Explanation: Osimertinib is specifically indicated for EGFR mutations. ALK
rearrangements are also targeted in NSCLC, although typically with different
medications (e.g., alectinib). This question may require clinical clarification, as
Tagrisso is EGFR-specific.
A 20-year-old male presents with long-standing gait issues (toe-walking),
frequent falls, difficulty standing, and stiffness. Symptoms began in childhood
and worsened over time. There is no relevant family history.
What is the most likely diagnosis?
✔✔ Becker Muscular Dystrophy
📝 Explanation: This is a milder, late-onset form of muscular dystrophy
