Use the following information to answer the next 2 questions.  Substances PQR is freely filtered and 100% secreted Plasma concentration of PQR = 140mg% Renal plasma flow = 590 mL/min Glomerular filtration rate = 115 mL/min Urine flow = 1 mL/min How much PQR is secreted by the tubules?

Use the following material to answer the next 4 questions. Cardiac output = 5.7 L/min Hematocrit = 40% Renal plasma flow = 650 mL/min Glomerular filtration rate = 110 mL/min Urine flow 1 ml/min Plasma K+ concentration 4 mEq/L (maintain units) Urine K+ concentration 35 mEq/L (maintain units) What is the filtration fraction?  

Use this same scenario for this question A 40-year old man is admitted to the hospital with acute renal failure after exposure to a toxic chemical spill at his workplace.  At his last yearly check-up, he was 70 kg, his blood analysis and urinalysis were unremarkable and his GFR was estimated to be 120 mL/min with a creatinine of 1 mg/dL.  Upon admission to the hospital, his plasma creatinine was 2 mg/dl.  Over the following week, his plasma creatinine rose to 4mg% and then came down to 3mg% and stabilized at 3 mg%.  How is the acute renal failure in this man best classified?

Consider the CO2/HCO3- buffer system with a pka of 6.1. If H2SO4 is added to this buffer system at a physiologic pH, one would expect an increased production of which of the following?

Cardiac output = 5.7 L/min Hematocrit = 40% Renal plasma flow = 650 mL/min Glomerular filtration rate = 110 mL/min Urine flow 1 ml/min Plasma K+ concentration 4 mEq/L (maintain units) Urine K+ concentration 35 mEq/L (maintain units) What is the renal fraction?

Consider the transporters in the proximal tubule and in the distal tubule that move H+ across the luminal membrane of nephron. Which of the following is a characteristic they have in common?

Use the following material to answer the next 4 questions.

A 60-year old woman is always thirsty and is unable to sleep for 8 hours at a time because she must get up to urinate. Her plasma osmolarity is 303 mOsm/L ((higher than normal) and her urine osmolarity is 70 mOsm/L (range is 70-1200 mOsm). Her plasma levels of ADH are higher than normal and her urine glucose is essentially zero.  What is the BEST explanation for the CAUSE of her condition?
