1. A 67-year-old man with a 50-pack-year smoking history presents
with worsening dyspnea and chronic cough. Spirometry shows
FEV1/FVC of 0.48 and FEV1 34% of predicted. His resting PaO2 is
50 mmHg on room air. Which intervention has been shown to
reduce mortality?
A) Inhaled corticosteroid
B) Long-acting beta agonist
C) Long-term oxygen therapy
D) Tiotropium
Answer: C
Rationale: Long-term oxygen therapy reduces mortality in COPD
patients with resting PaO2 ≤55 mmHg or evidence of cor
pulmonale.
2. A 48-year-old woman presents with acute-onset severe headache,
photophobia, and neck stiffness. Temperature is 39.8°C. CSF
shows 2600 WBC/μL (94% neutrophils), glucose 12 mg/dL (serum
100), protein 260 mg/dL. Gram stain shows gram-positive cocci in
pairs. Which is the most appropriate empiric antibiotic regimen?
A) Ceftriaxone + vancomycin
B) Ampicillin + gentamicin
C) Meropenem alone
D) Vancomycin alone
, Answer: A
Rationale: Community-acquired bacterial meningitis requires
third-generation cephalosporin plus vancomycin for resistant
pneumococcus.
3. A 59-year-old man with hypertension and type 2 diabetes
presents with acute substernal chest pain radiating to the jaw.
ECG shows ST elevations in leads V1-V4. Which is the most
appropriate next step?
A) Aspirin and immediate PCI
B) Aspirin and IV tPA
C) Aspirin and clopidogrel with medical management
D) Aspirin and urgent CABG
Answer: A
*Rationale: STEMI requires immediate reperfusion with PCI within
90 minutes if available; fibrinolysis if delay >90-120 minutes.*
4. A 73-year-old woman with atrial fibrillation on warfarin presents
with sudden onset of right arm weakness and aphasia. Last known
well 70 minutes ago. INR is 1.9. CT head shows no hemorrhage.
Which is the most appropriate next step?
A) IV tPA
B) Aspirin 325 mg
C) Mechanical thrombectomy alone
D) Heparin infusion
Answer: A
*Rationale: INR ≤1.7 is acceptable for IV tPA in patients on
warfarin; this patient qualifies within 3-hour window.*
5. A 33-year-old G2P1 at 31 weeks gestation presents with blood
pressure 172/106 mmHg and 4+ proteinuria. She reports a
persistent headache and epigastric pain. Which is the most
, appropriate management?
A) Labetalol and expectant management until 34 weeks
B) Magnesium sulfate and delivery at 34 weeks
C) Immediate cesarean delivery
D) Methyldopa and outpatient monitoring
Answer: C
Rationale: Severe preeclampsia with maternal symptoms
(epigastric pain, headache) at ≥31 weeks: delivery is indicated
after stabilization.
6. A 56-year-old man with heart failure with reduced ejection
fraction (EF 27%) presents with worsening dyspnea and
orthopnea. His medications include carvedilol, lisinopril,
furosemide, and spironolactone. Labs: K 6.4 mEq/L, creatinine 2.7
mg/dL (baseline 1.2). Which medication should be discontinued
first?
A) Carvedilol
B) Lisinopril
C) Furosemide
D) Spironolactone
Answer: D
Rationale: Life-threatening hyperkalemia on spironolactone plus
ACE inhibitor requires holding spironolactone first.
7. A 26-year-old woman presents with acute-onset shortness of
breath and right calf swelling 10 days after a long-haul flight. She
has no prior medical history. CT pulmonary angiography shows a
segmental pulmonary embolism. Which is the most appropriate
initial anticoagulation?
A) Warfarin alone
B) Apixaban alone
C) Enoxaparin followed by warfarin
, D) Unfractionated heparin infusion
Answer: B
Rationale: Direct oral anticoagulants (apixaban, rivaroxaban) are
first-line for acute PE in hemodynamically stable patients without
cancer.
8. A 47-year-old woman with systemic lupus erythematosus
presents with new-onset confusion and seizures. BP is 194/116
mmHg. Urinalysis shows RBC casts. Which finding on renal biopsy
is most characteristic of her condition?
A) Wire-loop lesions
B) Membranous thickening
C) Crescent formation
D) Focal segmental sclerosis
Answer: A
Rationale: Active lupus nephritis (class IV) shows wire-loop lesions
from subendothelial immune complexes.
9. A 66-year-old man presents with acute-onset left-sided weakness
and neglect. Last known well 3.5 hours ago. CT head shows no
hemorrhage. CT perfusion shows a small ischemic core with a
large penumbra. Which is the most appropriate treatment?
A) IV tPA alone
B) Mechanical thrombectomy alone
C) IV tPA followed by mechanical thrombectomy
D) Aspirin 325 mg
Answer: C
Rationale: Large vessel occlusion within 4.5 hours: IV tPA plus
mechanical thrombectomy if eligible and salvageable tissue
present.
