Question 1
What is the gold standard for the suspected diagnosis of Celiac
Disease?
A) Serum antibody testing
B) Genetic testing for HLA-DQ2/DQ8
C) Endoscopy with small intestine biopsy
D) Fecal fat analysis
Answer: C) Endoscopy with small intestine biopsy
Explanation: The gold standard for diagnosing Celiac Disease is endoscopy
with small intestinal biopsy, 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
osimertinib (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: Osimertinib (Tagrisso) is a third-generation EGFR tyrosine
kinase inhibitor 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 unremarkable. 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 ambulation into adulthood. Toe-walking, Gower's
sign (difficulty rising from sitting), and progressive weakness are
characteristic.
Question 4
, A female patient presents with an elevated ferritin level found on
previous laboratory work. She is asymptomatic with no significant
medical history. What should the provider do next?
A) Start iron chelation therapy immediately
B) Order genetic testing for hereditary hemochromatosis
C) Obtain a complete history and physical examination, including alcohol
use, inflammatory conditions, and repeat ferritin with iron studies
D) Refer for liver biopsy
Answer: C) Obtain a complete history and physical examination,
including alcohol use, inflammatory conditions, and repeat ferritin
with iron studies
Explanation: Elevated ferritin is nonspecific and can be caused by iron
overload, inflammation, infection, malignancy, liver disease, or alcohol use.
The next appropriate step is history-taking and repeat testing with iron
studies (serum iron, TIBC, transferrin saturation) to determine etiology
before proceeding with interventions.
Question 5
A 75-year-old female presents to the emergency department with an
irregular heart rate of 130 bpm and is diagnosed with atrial
fibrillation. Which medication would be appropriate for rate control?
