WK4: Key Terms Flashcards
Altered Fluid, Electrolyte & Acid-Base Balance
Anuria
Absent urine output
cirrhosis
An end-stage liver disease marked by interference of blood flow to the liver
and widespread hepatocyte (liver cell) damage
diuretics
Drugs that increase urine production
electrolytes
Ionizable substances in solutions; conduct electricity in solution
hypertonic
Solutions having a greater osmolality than the intracellular fluid
hypervolemia
Excessive increase of fluid in the extracellular compartment
hypotonic
Solutions having a lower osmolality than the intercellular fluid
hypovolemia
A decrease vascular volume
isotonic
Solutions with same osmolality as the intracellular fluid
lymphedema
- swelling in your soft tissues due to fluid build-up in your lymphatic system
Obstructed lymph flow with movement of fluid into the interstitium
oliguria
Reduced urine output
osmolality
Osmolar concentration in 1kg of water (mOsm/kg of H2O) ; used to describe fluid within the body
osmolarity
Osmolar concentration in 1L of solution ( mOsm/L); used when referring to fluids outside the body
osmoreceptor
Sensory neuron in the hypothalamus that promotes thirst
osmosis
Movement of water across a concentration gradient;
water movement to an area of higher concentration of particles ( less water content) from an area of lower concentration of particles ( more water content)
paracentesis
Insertion of a cannula into the peritoneal cavity for removal of ascetic fluid
turgor
Fullness; evaluation made on skin to determine hydration status
