Fluids Flashcards
Homeostasis
Delicate balance of fluids and electrolytes is maintained
True or false
Subtle changes can occur that often go unrecognized and untreated
True
True or false
Timely assessment and interventions prevent complications and saved lives
True
Where are bodily fluids found and gives examples
Intracellular and extracellular
- water
- electrolytes
- blood plasma
- proteins
- solutes
What percentage of intracellular fluid is there in the body?
67 %
What percentage of extracellular fluid in the body?
26%
What makes up extracellular fluid?
Intravascular fluid
Cerebral fluid
Intracellular fluid is
Inside the cell
- proteins , water, electrolytes, solutes
Extracellular fluid is
Outside the cell
- - sodium!,
Types of extracellular fluid
Whole blood - RBC / wbc/ plasma
What is the most critical component of the body’s overall fluid balance
Extracellular fluid
What are some causes of loss of intracellular fluid?
Diuretics
Bleeding
V/ d
Inadequate fluid intake
Interstitial fluid
Outside the blood vessels & b/w cells
Excess interstitial fluid is caused by
Edema
Intrapleural
Lubricates space b/w pleura acts as cushion for lungs
Synovial fluid function
Reduces friction between articulate cartilages of joints during movement
Cerebral spinal fluid is where
Around brain and spinal cord to cushion from injury and provide nutrients
What allows fluid to move
Osmotic pressure and hydrostatic pressure
What factors help determine fluid movement?
Intact/ functioning vascular tissue
Normal protein levels
Adequate hydrostatic pressure inside blood vessels
If albumin (enzyme) decreases what happens to homeostasis?
Edema
Leakage of intracellular fluid into interstitial areas causes a decrease in pressure
Osmolality
Measure of concentration of dissolved solutes in blood
What triggers the release of antidiuretic hormone in kidneys
Osmolality
Osmolarity
Proportion of dissolved particles in an amount of fluid
Osmolarity and Osmolality used interchangeably
True
Hypervolemia is
Excess fluid volume
What causes hypervolemia
Heart failure
Kidney failure
Cirrhosis
Hypovolemia is
The loss of fluid greater then output
What causes hypovolemia
V/d
Excessive sweating
Poor fluid intake
What are the 3 types intravenous solutions?
Isotonic
Hypotonic
Hypertonic
Isotonic solutions are
Similar concentration as blood
Hypotonic solutions
Lowers concentration of dissolved solutes than blood causing an imbalance
A person is dehydrated what type of solution would you use?
Hypotonic
Hypertonic solutions
Higher concentration of dissolved particles than blood
Increase of solutes in intravascular space compared to cells
Hypertonic
Why are electrolytes so important ?
Help w/ fluid regulation & bodily functions
Electrolyte abnormalities help you understand normal ranges and causes of imbalances
True or false
True
