A 45 y/o M presents with fever, productive cough with yellow sputum, and pleuritic chest pain. Vitals: Temp 38.5°C, HR 102, RR 24. CXR reveals right lower lobe consolidation. What is the most likely diagnosis?
💡 EXPLANATION:
Fever, purulent sputum, and CXR consolidation (white shadow) are hallmark signs of pneumonia. Asthma presents with wheezing. MI typically presents with crushing substernal pain. Pneumothorax presents with hyper-resonance and absent lung markings.

A patient on metformin and SSRIs presents with chronic watery diarrhea persisting during fasting. Stool osmotic gap is normal (<50 mOsm/kg). What is the most likely etiology?
💡 EXPLANATION:
Normal stool osmotic gap (<50 mOsm/kg) and diarrhea persisting during fasting indicate secretory diarrhea. Given the history, medications (metformin, SSRIs) are the most likely cause. Osmotic diarrhea (e.g., lactose intolerance) stops with fasting.
A 44 y/o F with cholecystitis develops fever (39.5°C), RUQ pain, and confusion on Day 3. BP 90/60 mmHg, HR 120/min. Labs show leukocytosis and hyperbilirubinemia. US reveals dilated intrahepatic ducts. What is the most likely diagnosis?

A 44 y/o F with cholecystitis develops fever (39.5°C), RUQ pain, and confusion on Day 3. BP 90/60 mmHg, HR 120/min. Labs show leukocytosis and hyperbilirubinemia. US reveals dilated intrahepatic ducts. What is the most likely diagnosis?
💡 EXPLANATION:
Reynolds pentad (Charcot triad + hypotension + confusion) confirms acute ascending cholangitis. This is a biliary emergency requiring antibiotics and urgent decompression. Duct dilation confirms obstruction. Cholecystitis rarely causes severe jaundice.

42y M, chronic alcoholic, presents with hand tingling, palpitations, and severe cramps. O/E: BP 110/96, Trousseau sign positive, DTR 4+ bilaterally. What is the most appropriate initial pharmacologic therapy?
💡 EXPLANATION:
Chronic alcoholism causes Mg wasting, leading to neuromuscular hyperexcitability (Trousseau sign, hyperreflexia) and refractory hypocalcemia. IV Magnesium sulfate is the specific treatment to correct the deficit and restore calcium homeostasis.

32y F p/w bloody diarrhea and fever (39.5°C) x2 days after eating undercooked eggs. She is immunocompetent with mild dehydration. Vitals are stable. What is the most appropriate management?
💡 EXPLANATION:
Non-typhoidal Salmonella is usually self-limited in immunocompetent adults. Treatment is supportive (fluids/electrolytes). Antibiotics are not indicated as they prolong the carrier state. Antimotility agents are contraindicated in bloody diarrhea.
A 4 y/o M presents with pallor and dark urine 2 weeks after an episode of bloody diarrhea. Labs: Hb 7.5 g/dL, Plt 95×10^9/L, Cr 168 µmol/L, and schistocytes on smear. Which triad defines this clinical syndrome?

A 4 y/o M presents with pallor and dark urine 2 weeks after an episode of bloody diarrhea. Labs: Hb 7.5 g/dL, Plt 95×10^9/L, Cr 168 µmol/L, and schistocytes on smear. Which triad defines this clinical syndrome?
💡 EXPLANATION:
Diagnosis is Hemolytic Uremic Syndrome (HUS), often post-diarrheal (STEC). The classic triad is Microangiopathic Hemolytic Anemia (MAHA), Thrombocytopenia, and Acute Kidney Injury (AKI). TTP adds fever and neuro signs.

A 37y/o M smoker, BMI 33 kg/m², reports 1-month retrosternal burning worsening after meals and when supine. No dysphagia or weight loss. Vitals are stable. What is the most appropriate initial management?
💡 EXPLANATION:
Classic GERD symptoms without alarm features (dysphagia, GI bleeding, weight loss) warrant an empiric trial of proton pump inhibitors (PPI) for 8 weeks. Endoscopy is indicated for alarm symptoms or treatment failure. Testing for H. pylori is not first-line for typical GERD.

A 40y/o F with obesity and DM2 presents with persistent RUQ pain, fever (38.6°C), and nausea for 12 hours. Exam reveals a positive Murphy sign. What is the most likely diagnosis?
💡 EXPLANATION:
Persistent RUQ pain (>6h), fever, and positive Murphy sign indicate acute cholecystitis due to cystic duct obstruction. Biliary colic typically resolves <6h without systemic signs. Cholangitis presents with Charcot triad (fever, RUQ pain, jaundice).

A 62 y/o M presents with sudden onset of large-volume, painless bright red blood per rectum. Vitals are stable. Abdomen is soft and non-tender. The bleeding stops spontaneously after 4 hours. What is the most likely diagnosis?
💡 EXPLANATION:
Diverticulosis is the most common cause of acute, painless, large-volume lower GI bleeding in patients >60 y/o. It results from the rupture of the vasa recta at the diverticular neck. Unlike ischemic colitis, it is painless.

A 27-year-old male unrestrained passenger in an MVC presents unresponsive. BP 60/33 mmHg, HR 180/min. FAST scan is positive. Blood samples are drawn immediately prior to fluid resuscitation. Which of the following is the most likely Hemoglobin finding?
💡 EXPLANATION:
In acute hemorrhage, whole blood (RBCs and plasma) is lost proportionally. Consequently, initial Hb and Hct remain normal. These values decrease only after hemodilution occurs via IV fluid administration or physiological fluid shifts.
