Normal Fluid and Electrolyte Balance Flashcards
Normal fluid and electrolyte balance means that the body
is at homeostasis/equilibrium
Normal body function depends upon…
fluid and electrolyte balance
1 Liter of water is equal to ___ lbs and ___ kg
2.2 lbs and 1 kg
Body fluid is composed od
chemical compounds (electrolytes)
blood cells
soluble molecules
2 things body regulates to achieve balance
-VOLUME of fluid in extracellular spaces
- water CONCENTRATION of solutes (osmolality) of all body fluids
Concentration of solutes in a solution
osmolality
3 Locations Body Fluid is found
-Vascular Fluid (in blood and lymph nodes)
-Interstitial FLuid (between cells)
-Intracellular Fluid (Within cells)
2 MAIN Types of body Fluid
Intracellular (ICF) located in cells (WATER)
-Extracellular (ECF) all fluid outside of cell (intravascular & interstitial spaces)
PRIMARY INTRACELLULAR ELECTROLYTES
Potassium
Phosphate
Sulfate
PRIMARY EXTRACELLULAR ELECTROLYTES
Sodium
Chloride
Bicarbonate.
Hormone released when body notices its not taking in enough fluids
ADH- Anti Diuretic Hormone (holds on to fluids body has left)
An IV bag is a L of fluid. T or F
True
Electrolytes have + and - Charge. T or F
True
the fluid in your vessels aka
Volume
Most important aspect of fluid balance is _____; w/o this, you cannot maintain ______
Volume; Blood pressure
2/3 of body contains:
1/3 of body contains:
water;
ECF
WHy is water important to body?
- Maintains normal body temp
-Waste Elimination - Transport nutrients to/from cells
- Maintain blood volume
Fluid found in intravascular space
Blood Plasma fluid component of blood
(Normal Saline- 0.9 % can be used as a replacement for this fluid)
liquid part of bloods
plasma
Loss of volume can lead to ____
Hypovolemic Shock
WHat kind of environment is needed for fluid and electrolyte imbalance?
ALKALINE
pH 7.37- 7.43
pH is determined by
H+ ions
hydrostatic pressure minus osmotic pressure
filtration pressure
Filtration occurs…
in glomerulus of kidneys
