NR 412 Exam #6 [Patho]
Kidney functions - correct answer ✔ ✔ -Produces erythropoietin
-Converts Vitamin D to its active form (facilitates Ca+ absorption)
-Responds to stimuli from ADH to cause water reabsorption
What is included in the upper urinary tract? Lower? - correct answer ✔
✔ Upper: kidneys and the ureters
Lower: bladder and he urethra
Function of nephron? - correct answer ✔ ✔ -Responsible for filtering
out blood to rid the body of wastes and reabsorbs substances that the
body needs
-Creates filtrate which forms urine for excretion
,Afferent arteriole - correct answer ✔ ✔ -Brings oxygen rick blood to
the blood to the glomerulus
-High pressure
2 types of capillaries involved in kidney filtration - correct answer ✔
✔ -Glomerular capillaries
-Peritubular capillaries
Efferent arteriole - correct answer ✔ ✔ -Help comprise arterial blood
supply to other parts of the nephron
-Low pressure
Peritubular capillaries - correct answer ✔ ✔ -Originate from efferent
arterioles
-Facilitate reabsorption of water and nutrients our body needs
-Excretion of wastes or excessive nutrients our body doesn't need
Where do peritubular capillaries empty? - correct answer ✔ ✔
Inferior vena cava
Specific gravity- what does it measure and whats the normal range? -
correct answer ✔ ✔ -Measure of urine concentration
, Normal= 1.010-1.025
Normal pH for urine? - correct answer ✔ ✔ pH: 4.6-8.0
-Most bacteria favor an alkaline environment
What does protein in the urine indicate regarding kidney function? -
correct answer ✔ ✔ Protein in the urine indicates abnormal
glomerular permeability seen with most kidney diseases
What is the most important measure of kidney function? - correct answer
✔ ✔ Glomerular Filtration Rate (GFR)
How does a decrease in renal blood flow affect GFR and urine output? -
correct answer ✔ ✔ GFR will decrease, urine output declines
Blood Urea Nitrogen (BUN) - correct answer ✔ ✔ Normal- 8-20
mg/dL
-Nitrogenous wastes that are the end product of protein metabolism
-Values affected by protein intake, tissue breakdown, GI bleeding, fluid
volume changes
