A 3-year-old child presents with a barking cough, inspiratory stridor, and low-grade fever. Neck X-ray shows a 'steeple sign.' What is the most likely diagnosis?
Answer: Viral croup (laryngotracheobronchitis)
Viral croup causes subglottic narrowing visible as the steeple sign on AP neck X-ray, with characteristic barking cough and inspiratory stridor.
A 48-year-old male presents with sudden severe 'thunderclap' headache described as the worst of his life. CT head is negative. What is the next most appropriate step?
Answer: Perform lumbar puncture to detect xanthochromia
A negative CT does not rule out subarachnoid hemorrhage; lumbar puncture detecting xanthochromia is required to exclude SAH when CT is negative.
A 32-year-old woman presents with pleuritic chest pain, malar rash, oral ulcers, and arthralgias. Lab work shows anti-dsDNA antibodies and low complement (C3/C4). What is the most likely diagnosis?
Answer: Systemic lupus erythematosus (SLE)
SLE is characterized by malar rash, oral ulcers, serositis (pleuritis), arthritis, and positive anti-dsDNA with low complement levels.
A 70-year-old male smoker presents with a 3-cm solitary pulmonary nodule found incidentally on chest X-ray. What characteristic would MOST suggest a benign lesion?
Answer: Popcorn calcification pattern
Popcorn calcification is characteristic of pulmonary hamartoma and is a reliable benign pattern, along with central, laminated, or diffuse calcification.
A 25-year-old male presents with urethral discharge and dysuria. Gram stain shows gram-negative intracellular diplococci. Which antibiotic regimen is currently recommended by CDC guidelines?
Answer: Ceftriaxone 500mg IM single dose plus doxycycline 100mg twice daily for 7 days
Current CDC guidelines recommend ceftriaxone 500 mg IM (or 1g if weight ≥150 kg) plus doxycycline (if chlamydia not excluded) for uncomplicated gonorrhea.
A 60-year-old woman presents with progressive difficulty climbing stairs and rising from a chair over 4 months, with proximal muscle weakness but no muscle pain. CK is mildly elevated. Which antibody is associated with dermatomyositis?
Answer: Anti-Mi-2
Anti-Mi-2 antibodies are highly specific for dermatomyositis (classic DM) and correlate with a good response to treatment.
A newborn is found to have bilious vomiting on day 2 of life. X-ray shows a 'double bubble' sign. What is the most likely diagnosis?
Answer: Duodenal atresia
Duodenal atresia produces the classic double bubble sign (distended stomach and proximal duodenum) and presents with bilious vomiting in the first 24-48 hours.
