Fluid and Electrolyte Balance Flashcards
Is the range that cells function within limited?
Yes
What does electrolyte concentration impact?
The elevtrical activity of both NERVE and MUSCLE cells
What is understanding the pathology of a disease
Understanding what is happening at the CELLULAR level
What is the most important electrolyte
Potassium
What is most important when it comes the body fluid and elevtrolytes
BALANCE
What does it mean if you have dry mucouses and feel dizzy
Dehydration
What should equal fluid gain
fluid loss
Why is it important to drink more water when you have a fever
Increased metabolic rate, mouth breathing
What type of fluid loss is difficult to measure
Insensible
What are some examples of insensible fluid loss
SKIN, LUNGS
What is insensible fluid loss effected by
Humidity and respiratory rate
What type of fluid loss is easy to measure
Sensible
What are some examples of sensible fluid loss
Urine, feces, wound drainage
Where is 2/3 of the total body water
Intracellular fluid
Where is 1/3 of the total body water
Extracellular fluid
What is the interstitial fluid
Between the cells and outside blood vessels
What is intravascular fluid
Inside blood vessels
What is blood plasma
Intravacular fluid
Where are lymph and transcellular fluids
Fluids around joints and organs
What are sweat and urine
Lymph and transcellular fluids
What are the three type of passive transposrt
DIFFUSION, OSMOSIS, FILTRATION
What is diffusion
Movement of SOLUTES from HIGH concentration to LOW conentration
What are some examples of solutes
Salt or sugar
What is osmosis
Movement of WATER across a selectively permeable membrane from an area of LOWER PARTICLE concentration to an area of HIGHER PARTICLE concentration
What is Filtration
Movement of WATER and SOULUTES in a solution from an area of HIGHER hydrostatic PRESSURE to LOWER hydrostatic PRESSURE
What type of transport uses energy
Active transport
What does active transport do
Uses energy to facilitate movement of PARTICLES across the cell membrane
What is osmolality
How SALTY we are (electrolytes)
What determines fluid osmolality
Concentration of dissolved particles
What is the normal osmolality range
275-295 mosm/kg
Where is sodium most abundant
ECF
Where is potassium most abundant
ICF
What particle determines the movement of water into/out of cells
Na
What are osmotic forces
The PRESSURE created when teo SOLUTIONS are different CONCENTRATATIONS and are SEPARTED by a selectively permeable mebrane
What is edema
FLUID EXCESS, in the INRERSTITIAL compartments
?How does edema manafest
Swelling and enlargement of tissues
Where does most edema happen
Butt, ankles, feet
What are some negativies related to edema
Can COMPRESS on vessels
What should you use to find the pulse if a pt has really bad edema
Pedopler
What are the four causes of edema
INCREASED CAPILLARY hydrostatice PRESSURE, LOSS of plasma PREOTEINS, OBSTRUCTION of LYMPATIC circulation, INCREASED CAPILLARY PERMEABILITY
Can water leave capillaries easily
Yes
What does increased capillary hydrostatic epressure do to BP
Increases BP
What does increased hydrostatic pressure do
PREVENTS fluid return at the VENOUS end or FORCES excessive amounts of fluids OUT into the TISSUES
What are some causes of increased hydrostatic pressure
prolonges sitting/standing, kidney disease and pregnacy (excess volume)
Why does prologed sitting/ standing cause increase hydrostatic pressure
Gravity and pressure
What is oncotic/ osmotic pressure
The difference of PROTEIN consentration between the capillaries and the surrounding tissue
What is the main protein that maintains osmotic pressure
Albumin
What are the three plasma proteins
Albumin, globulin, ribrinogen
What does globulin do
IMMUNE functioning
What does fibrinogent do
Blooc CLOTTING
Why does obsturction of lymphatic circulation cause edema
The extra fluid pools and is not picked up
What can cause obstruction of lymphatic circulation
Tumors, lumph node removal
Is swelling hard to get rid of
Yes
What can cause localized edema
inflammation or infection
Why does increased cappillary premeability cause edema
Increased PERMEABILITY, fluid movement into IS area, IS osmotic pressure
What would a burn or tramua cause
increased capillary permeability
