QUESTIONS WITH VERIFIED & REVISED
ANSWERS (NEW) 2026.
intracellular space

the space within a cell or cells.

extracellular space

space outside the cell

interstitial space

spaces between individual cells in the tissues

intravascular space

a space that includes the blood vessels and the heart

fluid tonicity

isotonic, hypotonic, and hypertonic

isotonic

when the concentration of two solutions is the same

fluid does not move

isotonic fluids

0.9% NS

LR

,Ringers Solution

D5W

hypotonic

there is less concentration of particles compared to another solution

the fluid moves toward where there is a higher concentration

cells swell and burst

fluid shifts out of the intravascular space

hypotonic fluids

0.45% NS

2.5% Dextrose in Water

hypertonic

there is a higher concentration of particles compared to another solution

the fluid moves into the intravascular space

cells in a hypertonic solution lose fluid and shrink

hypertonic fluids

3% NS

D5 .45% NS

D5 0.9% NS

D5 LR

D10 W

, D20 W

D50 W

colloids

contain molecules that are too large to pass through semipermeable membranes

expand intravascular volume by drawing fluid from the interstitial space into the intravascular

space

crystalloids

pass through semipermeable membranes
