GRADE A+
Aging population
Fast food
DM
HTN
Obesity - answer ✔✔-Risk for CKD
Filter protein, waste products and toxins
Returns vitamins, amino acids
Regulate fluid and electrolyte
Acid/base balance
BP control
RBC production
Maintain bone health - answer ✔✔-What do the kidneys do?
190 L - answer ✔✔-How much fluid/day go through the kidneys?
2 L - answer ✔✔-How much urine output/day?
Elimination and reabsorption - answer ✔✔-How does acid/base balance occur?
Renin angiotensin system
,Aldosterone control - answer ✔✔-How does BP control take place?
1. Renin converts angiotensinogen (from the liver) to angiotensin I
2. Angiotensin I --> angiotensin II (ACE enzyme)
3. Angiotensin II causes vasoconstriction which increases BP and causes release of aldosterone from
adrenal gland - answer ✔✔-How does the RAAS system work?
stimulates increased reabsorption of Na+, which increases water reabsorption and plasma volume
tries to replace volume to get BP up - answer ✔✔-How does aldosterone work?
Erythropoietin
Lower O2 level - answer ✔✔-Secreted to have body make more RBC
secreted in response to?
Their kidneys cannot secrete erythropoietin which decreases RBC - answer ✔✔-Why do kidney patients
become anemic?
Kidneys control Vitamin D activation aids in the absorption of calcium in the intestinal tract
Vitamin D helps our bones absorb calcium keeping our bones strong - answer ✔✔-How does the kidneys
maintain bone health?
Bone health - answer ✔✔-A huge problem for renal disease patients
Vasoconstriction or vasodilation
Increasing circulating blood volume
Renin secreted activating the RAAS
Aldosterone secreted by adrenal gland - answer ✔✔-How do kidneys regulate BP?
Creatinine
0.6-1.2 - answer ✔✔-Good indicator of how kidneys are functioning
,waste from muscle breakdown
normal ranges
Through our glomerulus, but we do not reabsorb through the tubules - answer ✔✔-How do we filter
creatinine?
there is something wrong with the filter - answer ✔✔-If creatinine levels go up
At least 50% of the kidney function is lost- and elevation in creatinine should be further assessed -
answer ✔✔-Creatinine does not increase until..
dehydrated, continual going up is usually decreased GFR - answer ✔✔-Creatinine can go up a little if...
Creatinine clearance
urine and blood
blood creatinine
87-107
107-239 - answer ✔✔-Amount of blood the kidneys can make creatinine free in a minute
Compare ___ and ____ to see how much creatinine is filtering
Blood is collected for 24 hours to do the test
If those numbers go down and we are not filtering out, then our ______ has gone up
Women normal range
Men normal range
BUN- blood urea nitrogen - answer ✔✔-Measures effectiveness of kidney excretion of urea nitrogen
Reabsorbed- not specific for kidneys- goes up and down when other things are going on
, nitrogenous waste that accumulates in the body
Breakdown of protein in the liver
makes urea - answer ✔✔-Where does urea come from?
Kidney filter urea nitrogen from blood
kidneys excrete the waste in urine elimination
Some days get reabsorbed in the tubules
Will increase w/ tubal disease and glomerular disease - answer ✔✔-How do we get rid of urea?
Increases
AKI causes it to increase along with infection, cancer treatment, steroids, tissue injury - answer ✔✔-
What happens to BUN in dehydration?
what else can cause this?
7-21 - answer ✔✔-Normal BUN
6-25 - answer ✔✔-BUN/creatinine ratio normal range
Tells you where the problem is in the kidneys- helps determine whether non-kidney-related factors,
such as decreased CO or RBC destruction are causing an increase
Because of BUN reabsorption, BUN increases faster than creatinine
Deficient fluid volume (dehydration) or decreased CO (BUN is higher than creatinine) - answer ✔✔-Pre-
renal BUN/creatinine ratio
If there is tubular destruction, which eliminates BUN reabsorption, BUN and creatinine will rise together-
suggest kidney dysfunction that is not related to dehydration or poor perfusion
The path through the tubules has been slowed down giving more time for reabsorption - answer ✔✔-
Intrarenal BUN/creatinine ratio
