Fluid and Electrolytes Basic Info Flashcards
How do kidneys maintain fluid balance
adjust urine volume & excrete electrolytes
How does ADH maintain fluid balance
vasopressin; controls water retention
how does the renin-angiotensin-aldosterone system maintain fluid balance
releases renin
how does aldosterone maintain fluid balance
water regulator
what acronym helps us remember the 7 functions of the kidneys
AWETBED
what does A stand for in AWETBED
A: controlling ACID-base balance
what does W stand for in AWETBED
W: controlling WATER balance
what does E stand for in AWETBED
E: maintaining ELECTROLYTE imbalance
what does T stand for in AWETBED
T: removing TOXINS and waste products from the body
what does B stand for in AWETBED
B: controlling BLOOD pressure
what does E stand for in AWETBED
E: producing the hormone ERYTHROPIETIN

D: activating VITAMIN D
What does ADH do for maintaining fluid balance
controls water retention
what is ADH referred to as
vasopressin
What does the Aldosterone (RAAS) system do to help maintain fluid balance
water regulator
Aldosterone (RAAS) regulates what?
Na and water
Aldosterone causes which organ to retain Na & water & excrete K
the kidneys
Is the K high or low when the aldosterone is low
high
Is the K high or low when the aldosterone is high
low
Aldosterone is released when Na is what and K is what
if Na is low and K is high
Aldosterone increases the reabsorption of and the excretion of what
reabsorption of Na and excretion of K
What is hypovolemia
ECF volume is reduced, results in decreased tissue perfusion
what can cause hypovolemia
salt and water loss
vomiting
diarrhea
diuretics
third spacing
Where does the salt and water loss come from during hypovolemia
from the ECF
