Ch 40 Fluid Electrolyte And Acid Base Balance Flashcards
Acid
Substance containing a hydrogen ion can be liberated or released
Acidosis
Condition characterized by a proportional excess of hydrogen ions in the extracellular fluid, in which the pH falls below 7.35
Active transport
Movement of ions or molecules across the cell membranes, usually against the pressure gradient and with the expenditure of metabolic energy
Alkalosis
Condition, characterized by proportionate lack of hydrogen ions in the extra cellular fluid concentration in which the pH exceeds 7.45
Anions
Ion that carries a negative electric charge
Antibody
Immunoglobulin produced by the body in response to a specific antigen
Antigen
Foreign material capable of inducing a specific immune response
Autologous transfusion
Occurs when a patient donates one’s own blood for a transfusion
Base
Substance that can accept or trap a hydrogen ion
Blood typing
The laboratory examination to determine a persons blood type
Buffer
Substance that prevents body fluids from becoming overly acid or alkaline
Capillary filtration
Passage of fluid across the wall of the capillary results from the force of blood pushing against the walls of the capillary
Cation
Ion that carries a positive electric charge
Colloid osmotic pressure
Pressure exerted by plasma proteins on permeable membranes in the body; synonym for oncotic pressure
Pulls fluid into the capillaries and/or prevents fluid from leaving
Cross matching
Act of determining the compatibility of two blood specimens
Dehydration
Decreased water volume in body tissue
Diffusion
Tendency of salutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration and tall equilibrium is established
Edema
Accumulation of fluid and extra cellular spaces
Electrolytes
Substance capable of breaking into ions and developing an electric charge when dissolved in solution
Extra cellular fluid ECF
Fluid outside the cells; includes intravascular and interstitial fluids
1/3 of adult body fluid
Na, Ca, Ch, bicarbonate
Most important in homeostasis
Hydrostatic pressure
Force exerted by a fluid against the container wall
In capillaries increases filtration by pushing fluid and solute out of the capillaries
Hypercalcemia
Excessive calcium in the extra cellular fluid
Hyperchloremia
Excess of chloride and the extra cellular fluid
Hyperkalemia
Excess of potassium in the extra cellular fluid
Hypermagnesemia
Excess of magnesium in the extra cellular fluid
Hypernatremia
Excess of sodium in the extra cellular fluid
Hyperphosphatemia
Above normal serum concentration of inorganic phosphorus
Hypertonic
Have a greater concentration than the solution with which it is being compared
Greater concentration of particles than plasma
Hypervolemia
Excess of plasma
Both water and Na are retained
Hypocalcemia
Insufficient amount of calcium in the extra cellular fluid
