FLUID & ELECTROLYTES
FLASHCARD EXAM WITH CORRECT
QUESTIONS AND ANSWERS 2025
o What is insensible loss - CORRECT-ANSWERSPerspiration and sweat
o What % of body fluid is ICF and where is ICF found - CORRECT-ANSWERS2/3 of
body weight-fluid inside of cells
o What is ECF - CORRECT-ANSWERS1/3 of body weight-fluid outside of cells
o What are the 3 components of the ECF - CORRECT-ANSWERSInterstitial,
Intravascular, Transcellular
o What is the interstitial space - CORRECT-ANSWERSFluid between the cells and outside
of blood vessels (contains lymph)
o How does adipose tissue and fat relate to a persons water quantity - CORRECT-
ANSWERSThe more adipose tissue and fat you 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
o What areas in the body have the highest amount of water - CORRECT-
ANSWERSMuscle, skin and blood
o What is the intravascular compartment - CORRECT-ANSWERSBlood plasma within the
vein
o What is the transcellular compartment - CORRECT-ANSWERSCSF, sweat, peritoneal,
synovial and pleural "protective component"
o What does the blood volume represent - CORRECT-ANSWERSWhat is inside the
intravascular space
, o What is the electrolyte unit of measurement - CORRECT-ANSWERSmEq
o What are 3 ways we intake water - CORRECT-ANSWERSDrinking, ingesting food and
oxidation of food during metabolic processes (500mL/day)
o What is Cl- "married" to---following each other - CORRECT-ANSWERSsodium
o What two electrolytes use mg/dL - CORRECT-ANSWERSCa++ and PO4-
o In acid base balance are we talking about arterial or venous side? - CORRECT-
ANSWERSArterial
o In fluid and electrolyte shifts are we talking about arterial or venous side? - CORRECT-
ANSWERSVenous
o What is the number one indicator for whether or not the patient has adequate fluid
balance and they are shifting their fluids properly - CORRECT-ANSWERSUrine output
o What is osmosis - CORRECT-ANSWERSmovement of FLUID from a LESSER solute
concentration to an area of GREATER solute concentration to equalize
o What is osmotic pressure - CORRECT-ANSWERSThe drawing power. If there is a high
solute concentration there is a high osmotic pressure that draws water into itself (ex.
intercranial pressure-diuretic pulling pressure off of the brain)
o What is osmolarity - CORRECT-ANSWERSTells us the amount of water in comparison
to the solutes
o What do hypertonic solutions have in them - CORRECT-ANSWERSMore molecules,
electrolytes and ions in them
o What do hypertonic solutions do to the cell - CORRECT-ANSWERSShrink it
o Why would you want to shrink a cell using hypertonic solutions - CORRECT-
ANSWERSHave too much ICF and the cell is too big and the intravacular space (blood
