The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 63-year-old man with diverticular disease comes to the emergency department because of painless rectal bleeding, dizziness, and lightheadedness for 2 hours. His temperature is 37.6°C (99.6°F), pulse is 115/min, respirations are 24/min, and blood pressure is 86/60 mm Hg. He appears pale. Physical examination shows bright red rectal bleeding. Colonoscopy shows profuse diverticular bleeding; endoscopic hemostasis is performed. After initiating fluid resuscitation, the patient becomes hemodynamically stable. The following day, laboratory studies show: Hemoglobin 8 g/dL Leukocyte count 15,500/mm3 Platelet count 170,000/mm3 Serum Urea nitrogen 60 mg/dL Creatinine 2.1 mg/dL Bilirubin Total 1.2 mg/dL Indirect 0.3 mg/dL Alkaline phosphatase 96 U/L Alanine aminotransferase (ALT, GPT) 2,674 U/L Aspartate aminotransferase (AST, GOT) 2,254 U/L Which of the following cells in the patient's liver were most likely damaged first?"   (A) Periportal hepatocytes   (B) Hepatic sinusoidal endothelial cells   (C) Hepatic Kupffer cells   (D) Centrilobular hepatocytes
