Fluid, Electrolytes, and Acid-Base Balance Important Terms Flashcards
acidosis
blood too acidic
alkolosis
blood too basic
anion gap
difference between concentrations of serum cations and anions
determined by measuring concentrations of sodium cations and chloride and bicarbonate anions
autologous transfusion
procedure in which blood is removed from a donor and stored for a variable period before it is returned to the donor’s own circulation
buffers
substance(s) that can absorb or release hydrogen ions to correct an acid-base imbalance
colloid osmotic pressure
abnormal condition of the kidney caused by the pressure of concentrations of large particles such as protein molecules that will pass through a membrane
crystalloids
salt solutions used for fluid replacement
extracellular fluid (ECF)
portion of body fluids composed of interstitial fluid and blood plasma
extravasation
when an IV becomes dislodged and IV fluid that contains additives that damage tissue enters subcutaneous tissue around the venipuncture site
filtration
the movement of fluid into and out of capillaries
hydrostatic pressure
pressure caused by a liquid
hypercalcemia
greater-than-normal amount of calcium in the blood
hyperkalemia
greater-than-normal amount of potassium in the blood
hypermagnesium
greater-than-normal amount of magnesium in the blood
hypernatremia
greater-than-normal amount of sodium in the blood
hypertonic
one solution has greater amount of solute than another, so solvent moves from second to first solution
hypotonic
one solution has a lesser amount of solute than another, so solvent moves from first to second solution
hypovolemia
abnormally low circulation of blood volume
infilitration
dislodging of IV from a vein into subcutaneous space
interstitial fluid
fluid that fills the spaces between most cells in the body
intracellular fluid (ICF)
liquid within the cell membrane
intravascular fluid
fluid circulating within the blood vessels of the body
isotonic
two solutions have the same concentration of solute so no movement happens
metabolic acidosis
abnormal condition of high hydrogen ion concentration in the extracellular fluid caused by increase in hydrogen ions or decrease in bicarbonate
metabolic alkalosis
abnormal condition characterized by the significant loss of acid from the body or increased levels of bicarbonate
oncotic pressure
total influence of the protein on the osmotic activity of the the plasma fluid
osmolarity
concentration or osmotic pressure of a solution expressed in osmoles or milliosmoles per kilogram of water
phlebitis
inflammation of a vein
respiratory acidosis
abnormal condition characterized by increased arterial carbon dioxide concentration, excess carbonic acid, and increased hydrogen ion concentration
respiratory alkalosis
abnormal condition characterized by decreased arterial carbon dioxide concentration and hydrogen ion concentration
transfusion reaction
systemic response by the body to the administration of blood incompatible with that of the recipient
venipuncture
technique in which a vein is punctured transcutaneously by a sharp rigid stylet (ie.: butterfly needle), a cannula (ie.: an angiocatheter that contains flexible plastic catheter), or a needle attached to a syringe
