Fluid & Electrolytes Test Questions with Verified Answers
What is insensible loss - -Perspiration and sweat
What two electrolytes use mg/dL - -Ca++ and PO4-
What % of body fluid is ICF and where is ICF found -
-2/3 of body weight-fluid inside of cells
In acid base balance are we talking about arterial or
venous side? - -Arterial
What is ECF - -1/3 of body weight-fluid outside of
cells
In fluid and electrolyte shifts are we talking about arterial
or venous side? - -Venous
What are the 3 components of the ECF - -
Interstitial, Intravascular, Transcellular
What is the number one indicator for whether or not the
patient has adequate fluid balance and they are shifting
What is the interstitial space - -Fluid between the their fluids properly - -Urine output
cells and outside of blood vessels (contains lymph)
What is osmosis - -movement of FLUID from a
How does adipose tissue and fat relate to a persons water LESSER solute concentration to an area of GREATER
quantity - -The more adipose tissue and fat you solute concentration to equalize
have the less water you will have b/c the fat is pushing out
the water or taking up the space where the water would
be What is osmotic pressure - -The drawing power. If
there is a high solute concentration there is a high osmotic
pressure that draws water into itself (ex. intercranial
What areas in the body have the highest amount of water pressure-diuretic pulling pressure off of the brain)
- -Muscle, skin and blood
What is osmolarity - -Tells us the amount of water in
What is the intravascular compartment - -Blood comparison to the solutes
plasma within the vein
What do hypertonic solutions have in them - -More
What is the transcellular compartment - -CSF, molecules, electrolytes and ions in them
sweat, peritoneal, synovial and pleural "protective
component"
What do hypertonic solutions do to the cell - -Shrink
it
What does the blood volume represent - -What is
inside the intravascular space
Why would you want to shrink a cell using hypertonic
solutions - -Have too much ICF and the cell is too
What is the electrolyte unit of measurement - -mEq big and the intravacular space (blood volume) is
dehydrated. So you hydrate intravascular by shrinking the
cell. Move fluid from ICF to ECF
What are 3 ways we intake water - -Drinking,
ingesting food and oxidation of food during metabolic
processes (500mL/day) What are some hypertonic IV solution examples - -
D10W, NS3-5%, D5W in 0.9%NS, D5W in 0.45% NS,
D5W in Lactated Ringers
What is Cl- "married" to---following each other - -
sodium
1/3
