UNIT 6 Flashcards
Body Fluid
A mixture of water, chemicals called elctrolytes and nonelectrolytes, and blood cells.
Fluid Compartments
Where body fluid is located.
usually two general components
Intracellular Fluid
- Fluid inside the cell
- Represents the greater portation of water in the body.
Extracelluar Fluid
- Remaining body fluid
- Fluid outside the cell
Interstitial Fluid
Fluid in the tissue space between or around cells
Intravascular Fluid
The watery plasma,or serum, portion of the blood
Electrolyetes
- Chemical compounds such as sodium and chloride
- Essential for maintaining cellualar, tissue, and organ functions
Ions
Substances that carry either a positive or a negative electrical charge
Cations
Electrolyetes with a positive charge
Anions
electrolytes with a negative
Nonelectrolyetes
Chemical compounds that remain bound together when dissoloved in a solution and do not possess an eletrical charge
Average Blood for adults
3L Plasma
2 L of blood cells
5L average circulating volume
Sodium Na
normal serum level
cation
135-148
Potassium K
normal serum level
cation
3.5-5.0
Chloride Cl
normal serum levels
Anion
90-110
What are 3 fluid components?
- intracellular
- extra cellular
- intrasituial
Examples of Nonelectrolyetes
Carbs
Protein
Fat
How are nonelectrolytes distruibuied in our body?
Osmosis Filtration Passive Diffusion Facilitated diffusion Active Transport
What can we not get rid of fluid?
Heart Failure
Edema
Kidney Failure
Pregnancy
What is everything measured in?
mL
Hypovolemia
Low volume of extracellular fluid
which results in dehydration and weight loss
MILD Dehyrdration
3%-5% loss of body weight
MODERATE Dehydration
6%-10% loss of body weight
SEVERE Dehydration
9%-15% loss of body weight
Hypervolemia
Higher than normal volume of intavascular fluid compartment
- Edema Develops
- also can cause circulatory overload
Foods HIGH in sodium
Peanut Butter Processed meat Processed foods Dairy Pickles Snacks ... you know sodium , like sodium(:
Circulatory Overload
Severly compromised heart function
3rd Spacing
Movement if intravascular fluid to non vascular fluid compartments
Hypoalbuminemia
Low albuminin the blood
-might indicate liver diease or kidney diease
Isotonic Solution
- Stays in vein
- 0.9% normal saline
- 5% Dextrose water
- Ringers solution or lactated ringers
- Maintain fluid balance
Hypotonic Solution
- Out of the vessels
- NaCl 0.45% also called half strength saline
- 5% saline in 0.45% saline
- People who need more fluid
Hypertonic Solutions
*Enters The vessles 3% saline 10% d10W 20% dextrose in water *Critical care unit
Crystalloid Soultions
Isotonic Solution
Hypotonic Solution
Hypertonic Solution
What do we include in patients intake?
- All the liquids a client drink
- foods that are liquid by the time they are swallowed
- IV solutions
- Fluid amdinstered through feeding tubes
What do we include in patients output
- Urine
- Emesis
- Blood loss
- Diarrhea
- wound/tube drainage
- aspirated irrigation
Fluid balance restored by?
- Ristricting or limiting oral fluids
- Reducing salt consumption
- Discounting/ Reducing IV fluid infusion
- Adminstering drugs to promote fluid elimination
- Combing all these interventions
when giving a dieretic you need to watch what?
The Electrolytes
Why are intravenous fluids infused into a vein?
- Maintain/restore fluid balance
- Maintain/replace Electrolytes
- Adminster viatmins
- Provide source of calories
- Admin rugs
- blood and blood products
Collioid Steroids
- Blood
- Components of Blood
- Plasma,WBC,Albumen, Platelets
Needle stick contributions?
Student
Imporoper disposal
Recapping needle NEVER DO
Why is a filter used for IV?
Reduce air bubbles
pedatric patients
adminster blood

How long can you hang blood before it is bad?
4 hours
How often do you change tubing?
Every 24 hours, or as order or policy says
What is the only solution compatable with blood?
Normal Saline
