NURS 5315 ADVANCED PATHO FLUID AND ELECTROLYTE EXAM
QUESTIONS AND ANSWERS A+ GRADED
Intravascular Fluid Compartment
8% of TBW
It's the Blood Plasma
Pattern of Fluid Shifts: blood pressure, vascular resistance
Interstitial Fluid Compartment
25% of TBW
It's the: fluid between cells, lymph, GI, spinal, eye/synovial fluids
Pattern of Fluid Shift: between plasma and interstitial: 4 starling forces
Intracellular Fluid Compartment
67% of TBW
Its inside the cells
Water moves freely across PM through aquaporin:ions trhough channel or transporter
What are reasons someone's TBW might not be 60%?
a. OB
b. Women about 50%
c. age (young children have high and old people have less like 40%)
Osmolality
the number of solute particles per 1 kg of solvent
Hydrostatic Pressure
pressure trying to create equilibrium: fluid moving to whatever happens in the
intravascular space (fluid moves out into interstitial space)
Oncotic Pressure
Fluid moves from interstitial to vascular. think of albumin
osmosis
water moving from low to high concentrations to create balance
Diffusion
freely movement follow concentration gradient (high to low concentration)
Active Transport
the energy it takes to move electrolytes across the cell membrane. Low to high
concentration
Isotonic Solution
the same number of solutes
hypotonic solution
it has less solutes and lower osmotic pressure so the fluid shifts from inside cell to
outside
hypertonic solution
has higher solutes/osmotic pressure therefore fluid shifts in to the cellular space
Sodium Homeostasis
it maintains homeostasis in the extracellular space and its maintained through osmosis
Potassium Homeostatis
It maintains homeostasis inside the cell and moves via active transport
