BOARD QUESTIONS WITH COMPREHENSIVE
RATIONALES
1. A 72-year-old patient presents with acute onset of severe headache,
photophobia, and nuchal rigidity. Vital signs are BP 160/90, P 110, R
22, T 101.2°F. Which diagnostic test is most critical to perform
immediately?
A. CT scan of the head without contrast
B. Lumbar puncture
C. MRI of the brain
D. EEG
Correct Answer: A. CT scan of the head without contrast
Rationale: Before performing a lumbar puncture to rule out meningitis,
a CT scan of the head without contrast must be done to exclude
increased intracranial pressure or mass effect, which would make
lumbar puncture dangerous. While lumbar puncture is the definitive
test for meningitis, it must be preceded by CT imaging in patients with
signs of increased ICP or focal neurological deficits.
2. A 45-year-old female with a history of systemic lupus
erythematosus presents with joint pain, fatigue, and a malar rash. She
is currently taking hydroxychloroquine. Which laboratory test should
be monitored routinely in this patient?
A. Complete blood count
,B. Serum creatinine
C. Ophthalmologic examination
D. Liver function tests
Correct Answer: C. Ophthalmologic examination
Rationale: Hydroxychloroquine can cause retinal toxicity, which is
irreversible. Routine ophthalmologic examinations, including visual field
testing and optical coherence tomography, are recommended at
baseline and annually after 5 years of therapy to monitor for early signs
of toxicity.
3. A 6-month-old infant is brought to the clinic for a well-child visit.
Which immunization should be administered at this visit?
A. MMR
B. Varicella
C. DTaP
D. Hepatitis A
Correct Answer: C. DTaP
Rationale: The DTaP (diphtheria, tetanus, and acellular pertussis)
vaccine is recommended at 2, 4, 6, and 15-18 months of age. MMR and
varicella are given at 12-15 months, and hepatitis A is given at 12
months.
4. A 55-year-old male with a history of coronary artery disease
presents with chest pain that occurs at rest and is relieved by
nitroglycerin. He has a history of hypertension and hyperlipidemia. His
medications include aspirin, atorvastatin, and lisinopril. Which
additional medication should be considered for secondary
,prevention?
A. Beta-blocker
B. Calcium channel blocker
C. Diuretic
D. ACE inhibitor
Correct Answer: A. Beta-blocker
Rationale: Beta-blockers are indicated for secondary prevention in
patients with coronary artery disease, especially those who have had a
myocardial infarction. They reduce mortality and recurrent
cardiovascular events by decreasing myocardial oxygen demand and
reducing heart rate.
5. A 30-year-old pregnant woman at 28 weeks gestation presents with
polyuria, polydipsia, and fatigue. Her fasting blood glucose is 140
mg/dL. Which of the following is the most appropriate initial
management?
A. Begin insulin therapy
B. Begin metformin
C. Begin glyburide
D. Begin dietary modification and exercise
Correct Answer: A. Begin insulin therapy
Rationale: In pregnant women with gestational diabetes, insulin is the
preferred pharmacological agent when fasting glucose is significantly
elevated. It does not cross the placenta and is considered safe.
Metformin and glyburide cross the placenta and have varying safety
profiles; dietary modification alone is insufficient with a fasting glucose
of 140 mg/dL.
, 6. A 65-year-old female presents with a 3-month history of progressive
memory loss, difficulty with executive functioning, and personality
changes. She has a history of hypertension and hyperlipidemia. Which
imaging study is most appropriate to evaluate for possible vascular
dementia?
A. CT scan of the head
B. MRI of the brain
C. PET scan
D. Carotid ultrasound
Correct Answer: B. MRI of the brain
Rationale: MRI of the brain is superior to CT for evaluating small vessel
ischemic changes, white matter disease, and microbleeds, which are
common in vascular dementia. It provides better resolution for
detecting subtle changes associated with cognitive decline.
7. A 22-year-old male presents with a painful, swollen right knee after
a basketball game. He has a history of recurrent joint swelling and was
previously diagnosed with hemophilia A. Which medication should be
avoided?
A. Acetaminophen
B. Ibuprofen
C. Hydrocodone
D. Celecoxib
Correct Answer: B. Ibuprofen
Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID)
that inhibits platelet aggregation and can increase the risk of bleeding in
