This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Excretory System (Kidney, Bladder) Acid-Base Balance, Subject name: Physiology
[{'content': 'A patient has a GFR of 100 ml/min, her urine flow rate is 2.0 ml/min, and her plasma glucose concentration is 200 mg/100 ml. If the kidney transpo maximum for glucose is 250 mg/min, what would be her approximate rate of glucose excretion? \nSelect and explain. \nA. 0 mg/min, B. 50 mg/min, C. 100 mg/min, D. 150 mg/min', 'role': 'user'}, {'content': 'Answer: A \nExplanation: The filtration rate of glucose in this example is: = GFR x plasma glucose concentration =(100 ml/min) x (200 mg/100 ml, or 2 mg/ml) =200 mg/min. Because the transpo maximum for glucose in this example is 250 mg/min, All of the filtered glucose would be reabsorbed and the renal excretion rate for glucose would be zero(0 mg/min).', 'role': 'assistant'}]
