Therapeutic Nutritional, Fluid, and Electrolyte Replacements Flashcards
Buffer
A substance that decreases the change in pH when an acid or base is added.
Colloid
A chemical system composed of a continuous medium throughout which small particles are distributed and do not settle out under the influence of gravity.
Dissociation
The act of separating into ionic compounds.
Electrolyte
A substance that dissociates into ions when placed in solution, becoming capable of conducting electricity.
Empirical
Based on observation and personal experience.
Hyperkalemia
An excess of potassium in the blood.
Hypernatremia
An excess of sodium in the blood.
Hypertonic solutions
Having an osmolality higher than 300 mOsm/L.
Hypokalemia
Abnormally low potassium concentration in the blood.
Hyponatremia
A deficiency of sodium in the blood.
Hypotonic solutions
Having an osmolality less than 300 mOsm/L.
Hypovolemia
Decreased volume of circulating blood.
Isotonic solutions
Having an osmolality equal to 300 mOsm/L.
Metabolic acidosis
Decreased body pH caused by excess hydrogen ions in the extracellular fluid.
Metabolic alkalosis
Increased body pH caused by excess bicarbonate in the extracellular fluid.
