|
|
|
Lab value for Magnesium (Mg++), ICF

|
|
|
ISF interstitial fluid
|
does not contain proteins, to big to pass through capillary walls. ISF is part of the ECF (extracelluar fluid). Surrounds each cell of the body; even bone cells are bathed in it.
|
|
|
Intravascular fluid (ECF), Extracellur fluid.
|
is the blood plasma, the liquid component of blood. It surrounds red blood cells and accounts for most of the blood volume.
|
|
|
The bodys fluid 2 major compartments
|
Inside the cells and outside the cells, the inside the cell fluid is ICF, consisting of 55% of total body fluid, and the rest is outside the cell (ECF), extracelluar fluid. Normally the distribution of fluids is constant.
|
|
|
ECF's 2 forms
|
Interstitial fluid and Intravascular fluid.
|
|
|
Interstitial fluid (ISF)
|
surrounds each cell of the body, even bone cells are bathed in it.
|
|
|
Intravascular Fluid
|
is blood plasma, the liquid component of blood, it surrounds red blood cells and accounts for most of the blood volume.
|
|
|
Transcellular Fluid
|
includes the cerebrospinal fluid and lymph. Contains secretions from salivary glands, pancreas, liver and sweat glands.
|
|
|
2 hormones that regulate fluid volume and concentration?
|
ADH - Antidiuretic, and aldosterone. ADH, is referred to as the water conserving hormone, affects fluid volume and concentration by regulating water retention. Aldosterone, acts to retain sodium and water.
|
|
|
The major intracelluar electrolytes are?
|
Potassium (K+) - 3.5 to 5.0 mEq/l and phosphous (P) - 2.5 to 4.5 mg/dl.
|
|
|
The major extracelluar electrolytes are?
|
Sodium (Na+) - 135 to 145 mEq/l and chloride (Cl-) - 96 to 106 mEq/l.
|
|
|
The movement solutes travel by?
|
Diffusion (passive transport) and active transport.
|
|
|
Passive transport (diffusion)
|
is a descender, molecules descent the contration gradient. Movement is from higher concentration to lower concentration.
|
|
|
Active transport
|
Molecules ascend against the gradient, movement is from lower concentration to higher concentration.
|
|
|
The pump that balances sodium and potassium?
|
Sodium - Potassium pump. In active transport, molecules are moved by physiologic pumps.This is one active transport pump.
|
|
|
Capillary filtration
|
is the movement of substances from an area of high hydostatic pressure, to an area of lower hydrostatic pressure.
|
|
|
Capillary reabsorption
|
Keeps filtration in check. During filtration, albumin (a protein that cant pass through capillary walls) remains behind in the diminishing volume of water. As the albumin concentration inside the capillaries increases, the albumin begins to draw water back in by osmosis. Water is thus reabsorbed by capillaries.
|
|
|
Hypertonic solutions are used for?
|
reducing the risk of edema, stabilizes blood pressure, and regulates urine.
|
|
|
A hypotonic solution causes fluid to?
|
Shift out of the blood vessels and into the cells and interstitial spaces.
|
|
|
The 3 basic methods for delivering IV therapy?
|
Continous infusion, intermittent infusion, and direct injection.
