Question

43. The renal clearance rate of creatinine, a nitrogenous waste product, is usually around 140 ml/mm. Which of the following is true? A. There is net secretion of creatinine. B. There is net reabsorption of creatinine. 44. Globulins are proteins normally found in blood plasma. Globulins are too large to pass through the glomerular filter into the initial filtrate. The renal clearance rate (RC) for globulins would be A. Close to zero. B. 125 ml/mm C. 125 mg/min D. Greater than 125 ml/mm. 45. The concentration of glucose in urine is normally close to zero. This is because A. Glucose does not pass through the glomerular filter. B. Glucose is reabsorbed. C. Glucose is secreted. 46. In diabetes mellitus, substantial amounts of glucose may be present in a person's urine. This would likely be because . A. The glomerular filtration apparatus is damaged. B. The osmotic gradient in the kidney is weaker than normal. C. The glomerular filtration rate is too low. D. The level of glucose in the blood is so high that the transport maximum (Tm) for glucose in the filtrate is exceeded.

Explanation / Answer

44. A. There is net secretion of creatinine.

The renal clearance rate of creatinnnine, a nitrogenous waste product, is usually around 140 ml/ min. So, there is net secretion of creatinine because it is exceeding the glomerular filtration rate (90 TO 120 ml/min).
