question: Q:A 52-year-old man is brought to the emergency department by ambulance after a motor vehicle accident. He was an unrestrained passenger who was ejected from the vehicle. On presentation, he is found to be actively bleeding from numerous wounds. His blood pressure is 76/42 mmHg and pulse is 152/min. Attempts at resuscitation fail, and he dies 25 minutes later. Autopsy shows blood in the peritoneal cavity, and histology of the kidney reveals swelling of the proximal convoluted tubule epithelial cells. Which of the following is most likely the mechanism underlying the renal cell findings?? 
  {'A': 'Decreased activity of caspase 7', 'B': 'Decreased function of the Na+/K+-ATPase', 'C': 'Increased activity of caspase 8', 'D': 'Increased activity of caspase 9', 'E': 'Increased function of the Na+/K+-ATPase'},
