Consider a 24 y/o 90 Kg male who has a blood glucose of 500 mg/dl. Glomerular function is normal and urinary flow rate is 3.88 L /day. What is the best estimate of his urinary glucose concentration?

What variable would change in the nephron in the presence of aldosterone? Increase or decrease in that variable? decrease urine volume to zero increase urine volume decrease urine volume result in no change in urine volume 0000

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

35. If a person has a kidney transport maximum for glucose of 175 mg/ min, a glomerular filtration rate (GFR) of 120 a plasma glucose level of 280 mg/100 mL. a unne flow rate of 2.0 ml/min, what would be the approximate rate of glucose excretion, assuming normal kidney functioning? Ans: B A. 161mg/min B. 0 mg/min C. 100mg/min D. 120 mg/min E. 175 mg/min

Lithium is a drug that is often used as a psychiatric medicine. It has the effect of blocking the production of aquaporins in the collecting duct and distal tubule, as well as damages the capillaries in the glomerulus. Q: Both protein and red blood cells are often found in the urine of those taking Lithium. Explain how this may occur.

Pressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?

The client for whom you are caring had the following for breakfast: 4 fluid ounces of milk, 6 fluid ounces of coffee, scrambled eggs, and one piece of toast. The client voided 4 fluid ounces of urine this morning. What is the person’s fluid intake in milliliters? What is the person’s fluid output in milliliters?

Can you help with the correct amount of glomerular filtrate This is not and will not be graded
