|
Name three objectives of IV therapy
|
1.) to maintain daily fluid requirments
2.) Replace present fluid losses 3.) Restore concurrent fluid losses |
|
|
Define the following:
Interstitial volume~ Intravascular volume~ |
Interstitial volume~ fluid between cells (lymph)
Intravascular volume~ plasma |
|
|
What is the most abundant electrolyte in intracellular fluid?
Extracellular? |
intracellular~ Potassium
extracellular~Sodium |
|
|
What is Intracellular fluid?
|
Intracellular fluid~ located within cells, 2/3 of total body weight, constists of 25L of fluid
|
|
|
What is extracellular fluid?
|
Consists of interstitial and intravascular fluids, as well as cerebrospinal/intraocular fluids, as well as GI secretions. 1/3 of total body weight, 15 liters of fluid,
|
|
|
What are the key elements of parenteral fluids?
|
1.) Water
2.) Carbohydrates 3.) Protien 4.) Vitamins 5.) Electrolytes |
|
|
Why is water important in our body?
|
(Most abundant) transports materials in and out of cells, helps regulate body temperature, helps with food digestion, medium for excreeting waste.
|
|
|
Osmotic pressure is effected by what? What is the osmoality of blood?
|
Osmotic pressure is effected by permebility of the membrane through which particles move. Blood osmoality is 310 mOsm/liter
|
|
|
What are isotonic fluids?
|
Isotonic fluids are the same as plasma, cells remain unchanged, water does not leave or enter the celles, EX
0.9%NS, D5W, Ringers, Ringer's lactate |
|
|
What are hypotonic fluids?
|
Water moves from intravascular space to intracellular. Used to treat electrolyte imbalnces, Cells swell, EX 0.45%Saline, 0.2%NS, 2.5% Dextrose
THINK HYPO~LESS (Less solution, more water) |
|
|
What are Hypertonic fluids?
|
Hypertonic fluids pull fluids into the vascular system, used for volume expansion, cells shrink, EX 10% Dextrose, D5.45% NS, D5NS
THINK HYPER=MORE MORE SOLUTE, LESS WATER |
