A 44-year-old man diagnosed with acute tubular necrosis has a blood urea nitrogen of 60 mg/dL and a blood glucose level of 100 mg/dL. A 2+ urine glucose is also reported. Questions: 1. State the renal threshold for glucose. 2. What is the significance of the positive urine glucose and normal blood glucose?

a. Using Table 10.1, identify the diseases that result when the filtration membranes within the kidneys become damaged and are unable to restrict or regulate the movement/filtration of larger substances. b. What kinds of disorders cause damage to the filtration membrane? ABNORMAL CONDITION CAUSE COMPONENT Caused by glucose levels in the blood that exceed the renal tubule's ability to reabsorb it. It is a common sign of diabetes mellitus. Glucose Glycosuria or Glucosuria Albumin Albuminuria Caused by damage to the glomerular and resulting in the leakage of large quantities of protein, including albumin, into the filtrate. filtration mer Red blood cells Caused by damage to the glomerular filtration membrane, allowing whole cells from the blood to pass into the filtrate. Hematuria Hemoglobinuria Caused by the hemolysis of red blood cells within the bloodstream, which releases hemoglobin into plasma that crossek the glomerular filtraton membrane during Hemoglobin renal filtration.
