Fluid, Electrolyte, & Acid-Base Balance Nursing Practice (NUR 3414)

Characteristics of Body Fluids
o       Fluid: water that contains dissolved/suspended substances such as glucose, mineral salts, &
proteins
o       Volume: fluid amount
o       Osmolality: fluid concentration; # of particles per kg of water
o       Fluid composition: electrolyte concentration
o       pH: degree of acidity

Scientific Knowledge Base: Location & Movement of Water & Electrolytes
o       Intracellular fluid (ICF): fluids w/in cells
•           2/3 of total body water
o       Extracellular fluid (ECF): fluid outside
of cells
•           1/3 of total body water
•           Three divisions:
•               Interstitial: fluid between
the cells & the outside of the blood vessels
•               Intravascular: liquid portion in our blood vessels (plasma)
•               Transcellular: fluid in the CSF, peritoneal, synovial

Electrolytes & Ions
o       Electrolytes: mineral salts; compounds that separate into ions (charged particles) when
they dissolve in water
o       Ions: charged particles
•           Cation: positively charged
•           Anion: negatively charged

Movement of Water & Electrolytes
o       Active transport: movement of ions against osmotic pressure to an area of higher pressure;
requires energy
•           Example: sodium-
potassium pump
o       Diffusion: passive movement of electrolytes or other particles down the concentration
gradient (from higher to lower concentration)
o       Osmosis: movement of water (or other solute) from an area of lesser to 1 of greater
concentration
