Insensible fluid losses
Fluid losses from the skin & lungs
Sensible fluid losses
Fluid losses from urination, defecation, wounds etc & can be measured
List the 3 basic fluid compartments
Intracellular & Extracellular (composed of Interstitial & Intravascular)
Normal saline solution is considered ___tonic, because the concentration of Na in the solution nearly equals the concentration of Na in the blood.
Isotonic
A solution of dextrose 5% in normal saline solution is considered ___tonic, because the concentration of solutes in the solution is greater than the concentration of solutes in the blood.
Hypertonic
Half normal saline solution is considered ___tonic, because the concentration of Na in the solution is lower than the concentration of Na in the blood.
Hypotonic
If a hypotonic fluid is given to a patient, it may cause too much fluid to move from the ___ into the ___, causing ____.
it may cause too much fluid to move from the veins to into the cells, causing the cells to swell.
If a hypertonic solution is given to a patient, it may cause too much fluid to be pulled ___ cells into the ___, causing ___.
it may cause too much fluid to be pulled from cells into the bloodstream, causing the cells to shrink.
Diffusion
solutes move from an area of higher concentration to an area of lower concentration, which eventually results in an equal distribution of solutes within the two areas.
Osmosis
passive movement of fluid across a membrane from an area of lower solute concentration and comparatively more fluid into an area of higher solute concentration and comparatively less fluid.
Capillary filtration
Movement of fluids through capillaries
Hydrostatic pressure
blood pushes against the capillary walls causing pressure which forces fluid & solutes through capillary wall.
Albumin
A large protein molecule that remains behind when fluid filters through capillary walls. As it's concentration inside the capillary increases, it acts as a magnet to attract water back into the capillary.
plasma colloid osmotic pressure
the osmotic/pulling force of albumin in the intravascular space. Avg: 25mm Hg
ADH
Antidiurectic Hormone - produced by the hypothalamus & stored & released by the posterior pituitary gland
