24. Measurements are made of the renal tubular fluid concentration of various substances along the length of the proximal tubule and plotted as the tubular fluid to plasma concentration ratio (TF/P). As these substances are reabsorbed along with water, the following profiles are obtained. (All substances are freely filtered at the glomerulus, the TF/P = 1 at the glomerulus.) Glucose is represented by which of the following curves? OA) [Tubular fluid] [Plasma] OB) 3.0- 2.0- 1.0- 0 B O C) E 25 50 75 Proximal tubule length (%) OD) 100 OE)

36. A 3-month-old boy is brought to the emergency department because of a 2-day history of lethargy. Physical examination shows no other abnormalities. The results of laboratory studies are shown: Serum Na+ 165 mEq/L (N=139-146) CI- 130 mEq/L (N=95-105) 334 mOsmol/kg H₂O (N=282-295) Osmolality Urine 1.001 Specific gravity Osmolality 117 mOsmol/kg H₂O (N>200) He is admitted to the hospital. His urine output is increased. His serum ADH (vasopressin) concentration is 24 pg/mL (N=1-5); aldosterone and renin concentrations are within the reference ranges. The urine osmolality remains unchanged after administration of 1-deamino-8-arginine vasopressin. An MRI of the brain and pituitary gland shows no abnormalities. Ultrasonography shows normal kidneys. The most likely underlying cause of the findings in this patient is a defect in which of the following? A) Angiotensin-converting enzyme B) Aquaporin C) 11a-Hydroxylase D) Renin E) Vasopressin receptors
