Water and Fluid Balance Flashcards
Signs of dehydration in infant
Sunken fontanels, sunken eyes , lethargy
What is diffusion ?
movement of particles down a concentration gradient
The concentration gradient
is the difference between the high and low concentration areas
What does diffusion depend on ?
Concentration gradient
membrane permeability
particle size
electrical potential across the membrane
Remember what cations and anions are
cations (+)
anions (-)
Fluid and electrolyte alterations can be treated with
IV solutions
Two main groups of IV solutions
Colloids and Crystalloids
Isotonic solutions have similar
solute concentration with plasma
Different isotonic solutions
Dextrose in water - D5W, Normal Saline, Lactated Ringer
Once you are giving fluids, you are always monitoring your
Intake and Output
Signs of Hypovolemia
Increased thirst dry mouth and swollen tongue weakness dizziness palpitations (feeling that the heart is jumping or pounding) confusion sluggishness feeling
Isotonic Fluid Excess is also known as
Hypervolemia
A bolus
is fluid given over a short amount of time, like 30 minutes. It is a higher amount than what a normal person could tolerate. Receiver could have trauma that necessitates a large amount of fluid intake
Deficits or excess of electrolytes are shown in
serum labs values
Potassium is _______________.
what is the normal range?
tightly regulated.
3.5-5 mEq/L
