Question 1: A 72-year-old male with a 45-pack-year history presents with a chronic cough and
hemoptysis. A CT scan reveals a solitary pulmonary nodule. Which of the following findings
on a biopsy would be most consistent with a diagnosis of small cell lung cancer?
A. Glandular formation with mucin production
B. Keratin pearls and intercellular bridges
C. Sheets of small cells with scant cytoplasm and "salt-and-pepper" chromatin
D. Multinucleated giant cells and granulomatous inflammation
CORRECT ANSWER: C. Sheets of small cells with scant cytoplasm and "salt-and-pepper"
chromatin
Rationale: Small cell lung cancer (SCLC) is characterized histologically by small, oval cells with
scant cytoplasm, finely granular ("salt-and-pepper") chromatin, and absent or inconspicuous
nucleoli. They often grow in sheets or clusters. Option A describes adenocarcinoma, Option B
describes squamous cell carcinoma, and Option D describes granulomatous disease.
Question 2: A 65-year-old female with type 2 diabetes presents with dysuria and suprapubic
pain. A urinalysis shows positive nitrites and leukocyte esterase. Which antibiotic is
contraindicated in this patient due to her age and potential for QT prolongation?
A. Nitrofurantoin
B. Trimethoprim-sulfamethoxazole
C. Ciprofloxacin
D. Fosfomycin
CORRECT ANSWER: C. Ciprofloxacin
Rationale: Fluoroquinolones like ciprofloxacin are associated with QT interval prolongation,
which poses a higher risk in older adults and those with electrolyte imbalances. Nitrofurantoin
(A) is a first-line agent for uncomplicated UTIs but is contraindicated if CrCl <60 mL/min. TMP-
,SMX (B) is another option but resistance is common. Fosfomycin (D) is generally safe and
effective for uncomplicated UTIs.
Question 3: A 78-year-old male with a history of atrial fibrillation is started on warfarin.
Which of the following dietary supplements should he be advised to avoid due to its
interaction that increases the risk of bleeding?
A. Glucosamine
B. Coenzyme Q10
C. Garlic
D. Vitamin D
CORRECT ANSWER: C. Garlic
Rationale: Garlic has antiplatelet properties and can potentiate the anticoagulant effect of
warfarin, increasing the risk of bleeding. Glucosamine (A) may potentiate warfarin but evidence
is weaker than garlic. Coenzyme Q10 (B) may decrease warfarin efficacy. Vitamin D (D) has no
significant interaction with warfarin.
Question 4: A 55-year-old post-menopausal female presents with gradual onset of bilateral
hand stiffness and pain, worse in the mornings, lasting over an hour. She also reports fatigue
and mild weight loss. Which serologic marker is most specific for the diagnosis of rheumatoid
arthritis?
A. Antinuclear antibody (ANA)
B. Rheumatoid factor (RF)
C. Anti-cyclic citrullinated peptide (anti-CCP) antibody
D. Erythrocyte sedimentation rate (ESR)
CORRECT ANSWER: C. Anti-cyclic citrullinated peptide (anti-CCP) antibody
Rationale: Anti-CCP antibodies have a high specificity (approximately 95%) for rheumatoid
arthritis, especially when compared to RF which can be elevated in other conditions. ANA (A) is
more associated with SLE. RF (B) is less specific. ESR (D) is a non-specific marker of
inflammation.
Question 5: A 45-year-old female presents with a blood pressure of 155/95 mm Hg. She has
no other comorbidities. Which of the following pharmacologic classes is recommended as
first-line therapy for hypertension in African American patients according to JNC 8?
A. ACE inhibitors
B. Angiotensin receptor blockers
C. Calcium channel blockers or thiazide diuretics
D. Beta-blockers
CORRECT ANSWER: C. Calcium channel blockers or thiazide diuretics
,Rationale: The JNC 8 guidelines recommend thiazide diuretics or calcium channel blockers as
first-line therapy for the general African American population (including those with diabetes),
as they were shown to be more effective than ACE inhibitors or ARBs in this population. Beta-
blockers (D) are not first-line for essential hypertension.
Question 6: A 68-year-old male presents with sudden onset of severe, tearing chest pain
radiating to his back. His blood pressure is 190/110 mm Hg. Which diagnostic test is the gold
standard for confirming this suspected diagnosis?
A. Chest X-ray
B. Computed tomography angiography (CTA)
C. Transthoracic echocardiogram (TTE)
D. Electrocardiogram (ECG)
CORRECT ANSWER: B. Computed tomography angiography (CTA)
Rationale: CTA of the chest is the gold standard for diagnosing acute aortic dissection due to its
high sensitivity and specificity. It allows visualization of the intimal flap and the extent of the
dissection. Chest X-ray (A) may show a widened mediastinum but is not confirmatory. TTE (C) is
less sensitive than TEE. ECG (D) is useful to rule out MI but does not diagnose dissection.
Question 7: A 60-year-old female with osteoporosis is prescribed alendronate. Which of the
following instructions should be provided to ensure proper absorption and minimize
esophageal irritation?
A. Take with a full glass of milk
B. Take with food to reduce gastric upset
C. Take on an empty stomach with plain water and remain upright for 30 minutes
D. Take at bedtime with a small snack
CORRECT ANSWER: C. Take on an empty stomach with plain water and remain upright for 30
minutes
Rationale: Alendronate must be taken on an empty stomach with a full glass of plain water (not
mineral water, juice, or milk) first thing in the morning. The patient must remain upright for at
least 30 minutes to prevent esophageal irritation and ulceration. Options A, B, and D are
incorrect and could reduce absorption or increase risk of esophagitis.
Question 8: A 62-year-old male with a history of COPD presents with worsening dyspnea,
increased sputum purulence, and volume. Which of the following antibiotics is most
appropriate for a patient with risk factors for Pseudomonas aeruginosa?
A. Azithromycin
B. Amoxicillin-clavulanate
C. Levofloxacin
D. Cefpodoxime
, CORRECT ANSWER: C. Levofloxacin
Rationale: Levofloxacin is a fluoroquinolone with good activity against Pseudomonas
aeruginosa, making it a suitable choice for exacerbations of COPD in patients with risk factors
(e.g., frequent exacerbations, severe airflow obstruction, or prior isolation of Pseudomonas).
Azithromycin (A) is a macrolide but not effective against Pseudomonas. Amoxicillin-clavulanate
(B) and Cefpodoxime (D) are not reliably effective against Pseudomonas.
Question 9: A 70-year-old male presents with painless jaundice, dark urine, and clay-colored
stools. He reports a 10-pound weight loss over the last two months. Which of the following is
the most likely diagnosis?
A. Viral hepatitis
B. Choledocholithiasis
C. Pancreatic cancer
D. Primary biliary cholangitis
CORRECT ANSWER: C. Pancreatic cancer
Rationale: Painless jaundice with weight loss in an older adult is a classic presentation for
pancreatic cancer, specifically cancer of the head of the pancreas. Viral hepatitis (A) typically
presents with flu-like symptoms. Choledocholithiasis (B) usually causes painful jaundice.
Primary biliary cholangitis (D) is more common in middle-aged women and presents with
fatigue and pruritus.
Question 10: A 55-year-old female with a history of asthma is prescribed a moderate-dose
inhaled corticosteroid (ICS) and a long-acting beta-agonist (LABA). Which of the following side
effects is she at the highest risk for?
A. Tachycardia
B. Oral candidiasis
C. Hyperkalemia
D. Hypoglycemia
CORRECT ANSWER: B. Oral candidiasis
Rationale: Use of inhaled corticosteroids (even with a LABA) increases the risk of oropharyngeal
candidiasis (thrush) due to local immunosuppression. This risk is mitigated by rinsing the mouth
after inhalation. Tachycardia (A) is more associated with beta-agonists. Hyperkalemia (C) and
hypoglycemia (D) are not typical side effects of ICS/LABA therapy.
Question 11: A 67-year-old male with chronic kidney disease stage 3 (eGFR 45 ml/min) is
diagnosed with gout. Which of the following medications should be used with caution or
avoided due to its renal clearance?
