ch 4 objectives

Question 1

identify and explain laboratory testing used to evaluate glomerular filtration

Answer 1

GFR
–> creatinine clearance
–> albumin

Question 2

identify and explain laboratory testing used to evaluate tubular reabsorption

Answer 2

osmolality/specific gravity

beta-microgloblin –> 99% reabsorbed so presence in the urine signifies tubular dysfunction

Question 3

creatinine clearance significance

Answer 3

measures how well glomeruli are filtering plasma

Question 4

how do you use glomerular filtration rate

Answer 4

measures amount of blood filtered by kidneys per minute
