<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 41-year-old man is brought to the emergency room after a blunt-force injury to the abdomen. His pulse is 130min and blood pressure is 7040 mm Hg. Ultrasound of the abdomen shows a large amount of blood in the hepatorenal recess and the pelvis. Which of the following responses by the kidney is most likely?? A: Decreased proton excretion, B: Decreased potassium excretion, C: Increased sodium reabsorption, D: Increased sodium filtration, E: Increased creatinine absorption,  <response>: This is a question about the renal response to hypovolemic shock caused by internal bleeding after abdominal trauma. The key findings are tachycardia, hypotension, and evidence of significant blood loss on ultrasound. In shock, the kidney responds by attempting to increase blood volume and blood pressure through several mechanisms. Choice A is incorrect because proton excretion would not be a primary focus. Choice B is incorrect because decreasing potassium excretion would not help restore blood volume. Choice C is correct because the kidney responds to volume loss by increasing sodium reabsorption to retain fluid. Choice D is incorrect because sodium filtration would not be increased in this situation. Choice E is incorrect because creatinine absorption does not play a major role in the shock response.C: Increased sodium reabsorption
