Write answer in between .Q:A 9-year-old boy is brought to the emergency department for the evaluation of diarrhea and vomiting for the last 2 days. During this period, he has had about 12 watery, non-bloody bowel movements and has vomited three times. He came back from a trip to India 3 days ago, where he and his family were visiting relatives. He has not been able to eat anything since the symptoms started. The patient has not urinated since yesterday. He appears pale. His temperature is 38C 100.4F, pulse is 106min, and blood pressure is 9660 mm Hg. Examination shows dry mucous membranes. The abdomen is soft with no organomegaly. Bowel sounds are hyperactive. Laboratory studies show:Hemoglobin 13 gdLSerumNa 148 mEqLCl- 103 mEqLK 3.7 mEqLHCO3- 19 mEqLUrea nitrogen 80 mgdLGlucose 90 mgdLCreatinine 2 mgdLIntravenous fluid resuscitation is begun. Which of the following is the most likely cause of this patients abnormal renal laboratory findings?? A: Decreased renal perfusion, B: Renal artery stenosis, C: IgA complex deposition, D: Glomerulonephritis, E: Urinary tract obstruction,  <response>: This is a clinical vignette about a 9-year-old boy with diarrhea, vomiting, and dehydration after returning from a trip to India. The key abnormal lab findings are an elevated BUN and creatinine, indicating acute kidney injury. The history of recent travel to India and presentation of profuse diarrhea suggests an infectious gastroenteritis, most likely viral or bacterial. The dehydration and reduced renal perfusion from the diarrhea and vomiting can cause prerenal azotemia, explaining the elevated BUN and creatinine. Choice A Decreased renal perfusion is the most likely cause of the abnormal renal labs in this setting of volume depletion from gastroenteritis. The other answer choices are less likely in an otherwise healthy child with this acute presentation.A: Decreased renal perfusion
